(c-maybe-re-mark-raw-string): Give a backward search limit to an operation which was needlessly lacking one. * cc-mode.el (c-doc-fl-decl-start, c-doc-fl-decl-end): Check a certain regexp is valid before performing the (somewhat expensive) actions of these functions. (c-fl-decl-start): In the search for a C++ lambda capture list, replace (slow) calculation of c-parse-state by a (less slow) c-go-up-list-backward. 2019-05-06 Alan Mackenzie c-beginning-of-statement-1: Handle syntactic WS macros properly. * cc-engine.el (c-beginning-of-statement-1): The variable before-sws-pos should record the position of a closing paren/brace/bracket before moving backwards over a sexp. When there is a syntactic WS macro between the starting point and the closing p/b/b, setq before-sws-pos again after moving backward over the macro. 2019-05-02 Alan Mackenzie Fix fontification of first item in CC Mode macro without parentheses * cc-engine.el (c-find-decl-prefix-search): Handle the new matching possibility (of a #define construct) in the new c-decl-prefix-or-start-re.

In particulr, handle multiline block comments whose newlines are not escaped. There is an example of this in #define EXTRA_CONTEXT_FIELDS in editfns.c. * cc-engine.el (c-beginning-of-macro, c-end-of-macro): Enclose the loops scanning escaped newlines with outer loops which check heuristically for, respectively, a block comment ender and a block comment starter on the lines we end up on. (A rigorous syntactic check would be too slow, here.) * cc-langs.el (c-last-c-comment-end-on-line-re) (c-last-open-c-comment-start-on-line-re): New language constants/variables. 2019-04-30 Alan Mackenzie CC Mode: in certain font lock loops, check point is not beyond limit. * cc-fonts.el (c-font-lock-enum-body, autodoc-font-lock-line-markup): As part of the `while' condition, check that the previous iteration of the loop hasn't moved point past `limit', thus obviating "wrong side of point" errors in re-search-forward, etc. 2019-04-27 Alan Mackenzie Fix slow scrolling in C++ buffers with lots of template delimiters. * cc-engine.el (c-update-brace-stack): bind c-parse-and-markup-<>-arglists and c-restricted-<>-arglists to t around the call to c-forward-<>-arglist, to force the marking of template delimiters with syntax-table text properties. 2019-04-26 Alan Mackenzie Fix the formatting of '\' (including apostrophes) in CC Mode. In particular, the second apostrophe must also get font-lock-warning-face. * cc-mode.el (c-parse-quotes-before-change, c-parse-quotes-after-change): Add cond arms to recognize and handle the anomalous construct '\'.

(c-before-change-check-raw-strings): Use new variable. (c-after-change-unmark-raw-strings): When typing into an opening delimiter or altering its close delimiter causes the opening delimiter to match a later closing delimiter, clear all syntax-table char properties from the opening delimiter onwards, and set c-new-END to point max. Also, when changing a closing delimiter, check whether its new value matches a previously open opening delimiter earlier in the buffer, and amend the syntax-table text properties appropriately. 2019-04-23 Alan Mackenzie Optimize for typing characters into long C++ raw strings. * cc-fonts.el (c-font-lock-complex-decl-prepare, c-font-lock-objc-methods) (c-font-lock-declarations, c-font-lock-enum-tail) (c-font-lock-cut-off-declarators, c-font-lock-enclosing-decls): If the chunk been fontified consists entirely of comments and strings, don't attempt to perform the function's action. * cc-mode.el (c-before-change-check-unbalanced-strings): Don't expand (c-new-BEG c-new-END) unnecessarily to the entire raw string being fontified. (c-fl-decl-start, c-fl-decl-end): When in a (raw or otherwise) string, don't return a position outside of the string (which used to cause unneeded fontification). 2019-04-20 Alan Mackenzie Fix Pike Mode's autodoc doc comments style's continued lines. * cc-engine.el (c-forward-sws, c-backward-sws): Recognize matches of c-doc-line-join-re as syntactic whitespace. (c-find-decl-prefix-search): Recognize and move over matches of c-doc-line-join-re as whitespace. (c-find-decl-spots): Before moving backward a char, check (bobp).

When this variable has a nil value, return nil as the value of the function. On encountering a } when scanning backwards, recognise this as the end of a previous construct and stop the scan. * decls-47.{cc,res}: New test files. 2019-03-30 Alan Mackenzie Allow a CC Mode derived mode to have strings delimited by single quotes. Also fix the bug where the delimiters of '\033', etc. got the error face. * cc-langs.el (c-single-quotes-quote-strings): Enhance the doc string. (c-string-delims): Change doc string to doc comment. * cc-mode.el (c-before-change-check-unbalanced-strings): In searches and comparisons, take account of the string delimiters possibly being '.

(c-guess-basic-syntax): Just before CASE 9C, move back to the previous brace list entry in the block, rather than to the first one. * bracelist-1.res, bracelist-11.res, bracelist-19.res, bracelist-2.res, bracelist-25.res, bracelist-26.res, bracelist-27.res, bracelist-3.res, bracelist-31.res, bracelist-4.res, bracelist-8.res, class-5.res, enum-2.res, enum-3.res, enum-6.res, enum-8.res, nested-1.res, whitesmith-1.res: Regenerate. 2018-06-08 Alan Mackenzie CC Mode: Fontify unbalanced quotes in unconstrained multiline strings, etc. ("Unconstrained" meaning that every string is multiline, without needing such special marking as used by Pike Mode.) * cc-mode.el (c-pps-to-string-delim): Don't process the char before BOB. (c-multiline-string-check-final-quote): New function. (c-bc-changed-stringiness): New variable. (c-before-change-check-unbalanced-strings): Add handling for unconstrained multiline strings. (c-after-change-re-mark-unbalanced-strings): Add handling for unconstrained multiline strings. Handle escaped double quotes more accurately. 2018-05-31 Alan Mackenzie Fix some bugs in c-before-change-check-unbalanced-strings. E.g. handle the last line having three quotes and no \n. * cc-mode.el (c-before-change-check-unbalanced-strings): Should we encounter a double quote marked with a string-fence syntax-table text property at the end of the last line, remove that property. 2018-05-25 Alan Mackenzie Amend c-before-change-check-unbalanced-strings to handle a quote at EOB. * cc-mode.el (c-before-change-check-unbalanced-strings): Before going back a sexp from the \n marked with a string-fence syntax-table text property, check that it is indeed a \n. If not, simply delete that text property from the isolated quote, not the quote and the \n which otherwise delimit an unterminated string. 2018-05-20 Alan Mackenzie Enhance CC Mode's fontification, etc., of unterminated strings. String delimiters, including escaped new lines, of correctly terminated strings are left in font-lock-string-face. All others get font-lock-warning-face. The latter get syntax-table text properties on the opening string delim and the "terminating EOL". Correct two miscellaneous bugs: the handling of text properties on Java Mode's generic delimiters; the handling of c-just-done-before-change. * cc-defs.el (c-point): New position 'eoll "end of logical line". (c-characterp): New macro. * cc-fonts.el (c-font-lock-invalid-string): Removed. (c-basic-matchers-before): Use a simple matcher in place of the form around c-font-lock-invalid-string. * cc-langs.el (c-get-state-before-change-functions): Add c-before-change-check-unbalanced-strings to the value for all modes except AWK Mode. Also add c-before-change-check-<>-operators to Java Mode, correcting an error in that mode's handling of generic delimiters. (c-before-font-lock-functions): Add c-after-change-re-mark-unbalanced-strings to the value for all modes except AWK Mode. (c-single-quotes-quote-strings, c-string-delims): New lang variables for future enhancements. (c-string-innards-re-alist): New lang variable. * cc-mode.el (c-just-done-before-change): Do not set this variable when a change is the alteration of text properties. (c-basic-common-init): Set parse-sexp-lookup-properties (and the XEmacs equivalent) also for Pike Mode. (c-neutralize-CPP-line): No longer neutralize unbalanced quotes here. (c-unescaped-nls-in-string-p, c-multiline-string-start-is-being-detached) (c-pps-to-string-delim, c-before-change-check-unbalanced-strings) (c-after-change-re-mark-unbalanced-strings): New functions. (c-after-change): Fix a bug with the handling of c-just-done-before-change. * string-2.{c,face}: Enhance to cover a new error situation. Recalculate the .face file. * string-1.face, string-3.face: Recalculate these files. 2018-04-19 Alan Mackenzie Amend c-colon-type-list-re also to handle compound identifiers * cc-langs.el (c-colong-type-list-re): Amend to recognize and skip over "::" in C++ and "." in Java. * inher-11.{cc,face}: New test files. 2018-04-07 Alan Mackenzie Purge obsolete file and tidy up Makefile. * cc-fix.el: Remove * cc-defs.el: Remove page which tested for various former conditions which used to need cc-fix to fix them. * Makefile: Remove all references to cc-compat.el, cc-lobotomy.el and cc-fix.el. 2018-04-02 Alan Mackenzie CC Mode: comment the use of "a\\`" as a regexp which will never match 2018-04-02 Alan Mackenzie Optimize c-syntactic-skip-backward, c-determine-limit for large comment blocks * cc-engine.el (c-ssb-lit-begin): Remove. (c-syntactic-skip-backward): Remove the surrounding c-self-bind-state-cache. Use the standard function c-literal-start in place of the special purpose c-ssb-lit-begin. With a suitable skip-chars argument (the usual case), optimize by invoking c-backward-syntactic-ws to move back over comment blocks. (c-determine-limit-get-base): Inovke an early c-backward-syntactic-ws. (c-determine-limit): Use c-forward-comment whilst moving forward. Cope with an empty position stack whilst looking for non-literals (bug fix). In the recursive call, double try-size to prevent Lisp stack overflow. 2018-03-28 Alan Mackenzie Handle C++17's constexpr keyword in if statements * cc-engine.el (c-after-conditional): Test for matches to c-block-stmt-hangon-key. * cc-langs.el (c-block-stmt-hangon-kwds): New lang const. (c-block-stmt-hangon-key): New lang const/var matching any element of the above. * if-10.{cc,res,face}: New test files. 2018-03-28 Alan Mackenzie Replace faulty non-matching regexp "\\<\\>" with "a\\`" The regexp "\\<\\>", which is supposed never to match, actually matches, for instance, where a Chinese character is directly followed by an ASCII letter. So, replace it with "a\\`". * cc-defs.el (cc-fix, c-make-keywords-re) * cc-engine.el (c-beginning-of-statement-1, c-forward-<>-arglist-recur) (c-forward-decl-or-cast-1, c-looking-at-decl-block) * cc-fix.el (top-level) * cc-langs.el (c-assignment-op-regexp, c-block-comment-ender-regexp) (c-block-comment-start-regexp, c-line-comment-start-regexp) (c-doc-comment-start-regexp, c-decl-start-colon-kwd-re) (c-type-decl-prefix-key, c-type-decl-operator-prefix-key) (c-pre-id-bracelist-key, c-enum-clause-introduction-re) (c-nonlabel-token-2-key) * cc-vars.el (c-noise-macro-with-parens-name-re, c-make-noise-macro-regexps): Replace "\\<\\>" by "a\\`". 2018-03-20 Alan Mackenzie * cc-engine.el (c-looking-at-or-maybe-in-bracelist): Remove pessimization 2018-02-02 Alan Mackenzie CC Mode: Fix an enum intro being parsed as defun-block-intro * cc-engine.el (c-inside-bracelist-p): Return a bufpos rather than t for the enum case. (c-add-stmt-syntax, c-guess-continued-construct): Replace c-looking-at-or-maybe-in-bracelist by c-inside-bracelist-p, since the former does not recognize enum brace lists, but the latter does. * cc-fonts.el (c-get-fontification-context): Replace c-looking-at-or-maybe-in-bracelist by c-inside-bracelist-p. * bracelist-31.{c,res}: New test files. 2018-01-30 Alan Mackenzie Fix @examples in cc-mode.info, where lines were getting glued together. This happened because of false @c's in macro lines. * cc-mode.texi (Line-up Functions): Remove the unneeded @c from macros sssTBasicOffset, sssTsssTBasicOffset, and hereFn. 2018-01-28 Alan Mackenzie Fix some errors in c-display-defun-name when the type is "struct {..}", etc. Also fix some errors with c-display-defun-name when there are nested classes. * cc-cmds.el (c-in-function-trailer-p): Deal with a struct {..} being merely the type of a function. (c-where-wrt-brace-construct): Deal with a struct {..} being merely the type of a function. Rearrange the order of some Lisp forms. Insert a check for c-protection-key ("private", etc.) alongside the checking for a label. (c-defun-name-1): New function extracted form c-defun-name, which works within the existing restriction. Don't regard 'at-function-end as being within the defun any more. Recognize "struct", etc., with the new c-defun-type-name-decl-key rather than c-type-prefix-key. Make the recognition of a normal function more accurate. (c-defun-name): Part left after extracting the above function. It now just widens and calls c-defun-name-1. (c-declaration-limits-1): New function extracted from c-declaration-limits, which works within the existing restriction. Move LIM back one block to account for the possibility of struct {..} as a function type. Check we're not inside a declaration without braces. (c-declaration-limits): Part left after extracting the above function. It now just narrows to an enclosing decl block and calls c-declaration-limits-1. (c-defun-name-and-limits): New function which identifies the name and limits of the most nested enclosing declaration or macro. (c-display-defun-name): Use c-defun-name-and-limits rather than two separate functions (which didn't always agree on which function). * cc-engine.el (c-beginning-of-statement-1): If we have struct {..} as the type of a function, go back over this, too. * cc-langs.el (c-defun-type-name-decl-kwds, c-defun-type-name-decl-key): New lang const/var. 2018-01-21 Alan Mackenzie Handle C99 Compound Literals in return statements and argument lists. * cc-engine.el (c-looking-at-or-maybe-in-bracelist): Recognize a brace list when preceded by "return" or inside parentheses, either immediately after the "(" or following a comma. (c-looking-at-inexpr-block): Test c-has-compound-literals rather than hard coded C++ Mode. (c-guess-basic-syntax, CASE 7B): Test additionally for not being just inside a parenthesis or being at a Java "new" keyword. CASE 9: Remove the simple minded test on the contents of a block to determine a brace list. * cc-langs.el (c-has-compound-literals): New lang const and lang var. * bracelist-30.{c,res}: New test files. 2018-01-16 Alan Mackenzie C++ Mode: Fontify correctly uniform initialisation with inner parentheses. E.g.: someStruct x ( (nullptr != y) ? 3 : 4 ) Also fontify declarations of function pointers correctly. * cc-engine.el (c-forward-decl-or-cast-1): While testing for a typeless declaration, additionally test the variable `got-prefix' to recognize a function pointer in parentheses. Allow c-fdoc-shift-type-backward to be invoked when we have nested parens. * decls-43.{cc,face}, knr-6.face: New test files. 2017-12-19 Alan Mackenzie Fontify a CPP construct correctly when a comment follows without spaces Do this by removing a broken optimization in the state cache which put category text properties on a character between the end of the CPP construct and the beginning of the comment. This can't work when there's no such character. * cc-defs.el (c-cpp-delimiter, c-set-cpp-delimiters, c-clear-cpp-delimiters) (c-comment-out-cpps, c-with-cpps-commented-out) (c-with-all-but-one-cpps-commented-out): Remove. * cc-engine.el (c-no-comment-end-of-macro): Return the comment start position rather than one character before it. (c-invalidate-state-cache, c-parse-state): Remove the invocations of c-with-all-but-one-cpps-commented-out and c-with-cpps-commented-out. * cc-mode.el (c-neutralize-syntax-in-and-mark-CPP): Rename to c-neutralize-syntax-in-CPP and remove the bits which applied category properties. * cc-langs.el (c-before-font-lock-functions): Incorporate the new name of the function c-neutralize-syntax-in-CPP. * macro-30.{cc,face}: New test files. 2017-12-19 Alan Mackenzie Fix loss of documentation face in certain CC Mode doc comment situations * cc-fonts.el (c-font-lock-doc-comments): Take into account the possibility of font-lock-comment-delimiter-face. Test rigorously for "/**" (etc.) being itself inside a literal, rather than just depending on the face of the previous character. 2017-12-14 Alan Mackenzie Fix fontification of first declaration within a C++ lambda form. * cc-engine.el (c-looking-at-or-maybe-in-bracelist): Cease spuriously recognizing the braces of a lambda form as a brace list when there is an "=" preceding the introductory brackets. * lambda-4.{cc,face}: New test files. 2017-12-14 Alan Mackenzie Fix misfontification of C++ member initialization list after "throw" * cc-engine.el (c-forward-type): Stop recognizing a "type" starting with "throw", by using c-opt-type-modifier-prefix-key. * cc-langs.el (c-type-modifier-prefix-kwds): New lang const which, in C++, doesn't contain "throw", otherwise like c-type-modifier-kwds. (c-opt-type-modifier-prefix-key): New lang const and var, a regexp matching any keyword in the previous lang const. * constructor-2.{cc,face}: New test files. 2017-12-13 Alan Mackenzie Don't misfontify "foo ()" inside C++ initialization parentheses as a type Also recognize and handle function names introduced by "extern" inside a function. * cc-engine.el (c-forward-decl-or-cast-1): Add a new element to the result list which is t when our declaration is, or is to be treated as, being at top level. * cc-fonts.el (c-get-fontification-context): Detect being inside a C++ uniform initialization and return (not-decl nil) for this case. (c-font-lock-declarations): Use the new element 4 of the result of c-forward-decl-or-cast-1. * cc-langs.el (c-make-top-level-kwds, c-make-top-level-key): New lang consts/vars. * statement-26.{cc,face}: New test files. * templates-12.face: Recalculate this face file. 2017-11-21 Alan Mackenzie Make c-defun-name analyze more thoroughly a function type which is a struct This fixes bug #29293. * cc-cmds.el (c-defun-name): When a struct (etc.) type is encountered, check whether it is the return type of a function rather than a declaration of the struct itself. Similarly adapt the cond arm which deals with functions properly to recognize struct return types. 2017-11-12 Alan Mackenzie CC Mode: Fix defun-open being recognized as brace-list-open at EOB. * cc-engine.el (c-looking-at-statement-block): Add handling for an open brace at EOB and nested braces inside an unclosed brace block. * bracelist-29.{c,res}: New test files. 2017-11-10 Alan Mackenzie Correct the indentation of C99's compound literals. * cc-engine.el (c-looking-at-statement-block): Amend so that if there is only syntactic whitespace in a brace block, it is regarded as a statement block. Also, if there is no semicolon or comma delimiter, treat as a statement block when there is a keyword. (c-guess-basic-syntax): CASE 9 test: Regard a brace as starting a brace block when its contents indicate a brace block. * bracelist-28.{c,res}: New test files. * constants-3.face: Correct this facefile after amendments unrelated to the above. 2017-11-09 Alan Mackenzie Correctly indent C++14 brace lists which are a second argument to a function. In particular, don't indent contained brace lists in "staircase" fashion. This fixes bug #28623. * cc-engine.el (c-looking-at-or-maybe-in-bracelist): When testing for being enclosed in parens, recognise also a brace directly following a comma, as well as a brace being the first thing inside the paren. Enhance the return value, by indicating when we're directly inside an open paren. (c-inside-bracelist-p): Add an extra argument ACCEPT-IN-PARAM which indicates whether we will accept a bracelist directly inside an open parenthesis. Simplify the manipulation of PAREN-STATE by dispensing with variable LIM and using c-pull-open-brace. Enhance the return value, respecting the new argument. (c-guess-basic-syntax): Save a copy of the initial parse-state in the new variable STATE-CACHE. Use this variable in place of C-STATE-CACHE throughout the function. At CASE 7B, call c-inside-bracelist-p with extra argument nil. At CASE 9, call that function with extra argument t. * bracelist-2.res. Reflect the now more accurate parsing available. * bracelist-25.{cc,res,face}. Re-indent a brace list, and recalculate the .res and .face files. * bracelist-26.{cc,res}. New test files. * bracelist-27.{cc,res}. New test files. 2017-11-03 Alan Mackenzie Introduce a function to CC Mode which displays the current function name Remove an erroneous interactive specification from two functions. * cc-cmds.el (c-display-defun-name): New command. (c-defun-name, c-cpp-define-name): Remove interactive specification. * cc-mode.el (c-mode-base-map): Add binding C-c C-z for the new command. * cc-mode.texi (Other Commands): Add documentation for the new command. 2017-10-30 Alan Mackenzie Fix "Args out of range" error in c-determine-limit. * cc-engine.el (c-determine-limit-get-base): If the candidate position for BASE is below point-min, scan forward to the end of the current literal. (c-determine-limit): Add an extra arm to the final cond form, testing for BASE being at point-min. 2017-10-26 Alan Mackenzie Fix another "wrong side of point" error in CC Mode. This fixes (a follow-up to) bug #28850. A internal generated form for scanning text to fontify had a LIMIT parameter. It also locally bound LIMIT to a value possibly beyond the original LIMIT, allowing point to move beyond the original LIMIT, and to create the wrong side error. Fix it by checking point is not beyond LIMIT in the outer context before using it. * cc-fonts.el (c-make-font-lock-search-form): Add a new parameter CHECK-POINT which, when non-nil, directs the function to generate a check on point. (c-make-font-lock-context-search-function): Invoke the above function with new argument value t. 2017-10-25 Alan Mackenzie Fix a "wrong side of point" error in CC Mode. Fixes bug #28850. The cause was a scanning over a bracket pair taking us beyond the supplied LIMIT parameter in c-forward-declarator. * cc-engine.el (c-forward-declarator): Add three checks (< (point) limit) whilst dealing with tokens after the declared identifier. * cc-fonts.el (c-font-lock-declarators): Don't supply a LIMIT argument to `c-forward-declarator' (twice), since we want to fontify up till the end of a declarator, not an arbitrary jit-lock chunk end. 2017-10-22 Alan Mackenzie Refactor c-forward-token-2 with new function c-forward-over-token-and-ws. Use the new function directly in several places where c-forward-token-2 wouldn't move over the last token in the buffer. This caused an infinite loop in c-restore-<>-properties. * cc-engine.el (c-forward-over-token-and-ws): New function, extracted from c-forward-token-2. (c-forward-token-2): Refactor, calling the new function. (c-restore-<>-properties): Fix infinite loop. (c-forward-<>-arglist-recur, c-in-knr-argdecl) (c-looking-at-or-maybe-in-bracelist): Call the new function directly in place of c-forward-token-2. * cc-cmds.el (c-defun-name) Call the new function directly in place of c-forward-token-2. * cc-fonts.el (c-font-lock-enclosing-decls): Call the new function directly in place of c-forward-token-2. 2017-10-04 Alan Mackenzie Fontify untyped function declarations in C Mode correctly. Also correct two bugs where deleting WS at a BOL could leave an untyped function declaration unfontified. * cc-engine.el (c-find-decl-spots): Don't set the flag "top-level" when we're in a macro. (c-forward-decl-or-cast-1): Recognize top-level "foo(bar)" or "foo()" in C Mode as a implicitly typed function declaration. (c-just-after-func-arglist-p): Don't get confused by "defined (foo)" inside a macro. It's not a function plus arglist. * cc-langs.el (c-cpp-expr-functions-key): New defconst and defvar. * cc-mode.el (c-fl-decl-end): After c-forward-declarator, move over any following parenthesis expression (i.e. parameter list). (c-change-expand-fl-region): When c-new-END is at a BOL, include that line in the returned region, to cope with deletions at column 0. * decls-19.{c,face}, knr-5.{c,face}: Fix for the new correct recognition of typeless functions. * macro-17.face, toplevel-label-1.face: Regenerate to cope with changed handling of invalid constructs. 2017-10-02 Alan Mackenzie Fix a CC Mode brace stack cache bug. * cc-engine.el (c-update-brace-stack): Call c-beginning-of-current-token after a failing search operation, to ensure we don't cache a point inside a token. 2017-09-18 Alan Mackenzie Fix irregularities with CC Mode fontification, particularly with "known types" * cc-fonts.el (c-font-lock-declarators): Introduce a new optional parameter, template-class. In "class ", fontify "Y" as a type. (c-font-lock-single-decl): New variable template-class, set to non-nil when we have a construct like the above. Pass this as argument to c-font-lock-declarators. (c-font-lock-cut-off-declarators): Check more rigorously that a declaration being processed starts before the function's starting position. (c-complex-decl-matchers): Remove the redundant clause which fontified "types preceded by, e.g., "struct"". * cc-langs.el (c-template-typename-kwds, c-template-typename-key): New lang defconsts and defvar. 2017-09-15 Alan Mackenzie Cope better with C++ and Objective-C protection keywords in class declarations This fix fixes the fontification of method inside a class at the time it is typed, when there is a protection keyword clause preceding it. * cc-engine.el (c-forward-keyword-clause): Handle protection keywords. (c-looking-at-decl-block): Avoid scanning forward over protection keyword clauses too eagerly. * cc-langs.el (c-protection-key c-post-protection-token): New lang defconsts and defvars. * cc-mode.el (c-fl-decl-start): When we encounter a protection keyword following a semicolon or brace, move forward over it before attempting to parse a type. 2017-09-12 Alan Mackenzie Don't match C++ template delims starting within a token. FIxes bug #28418. * cc-engine.el (c-restore-<>-properties): After failing an attempted match from the start of a token (in particular, "<<"), move to the next token rather than the nex character before searching for the next "<". 2017-09-03 Alan Mackenzie Correct the fontification of quote marks after buffer changes in CC Mode. * cc-mode.el (c-parse-quotes-before-change, c-parse-quotes-after-change): Rewrite the functions, simplifying considerably, and removing unnecessary optimisations. Invalidate two caches after manipulating text properties. 2017-09-03 Alan Mackenzie Fix fontification of "operator~" in C++ Mode. * cc-langs.el (c-ambiguous-overloadable-or-identifier-prefices) (c-ambiguous-overloadable-or-identifier-prefix-re): New c-lang-defconsts/vars. * cc-engine.el (c-forward-name): Do not try to parse "~" (and two other symbols) as a cast without good evidence. Prefer an overloaded operator in ambiguous cases. * operator-3.{cc,face}: New test files. 2017-08-31 Alan Mackenzie Fix a glitch in CC Mode's syntactic whitespace cache. * cc-engine.el (c-forward-sws): Deal correctly with a block comment close at the end of a macro. 2017-08-31 Alan Mackenzie Correct the fontification of C++ Mode enclosed declarations. * cc-fonts.el (c-font-lock-enclosing-decls): abolish the spurious check that the character before the start of an enclosed declaration must be ; or }. It might also be {. * operator-3.{cc,face}: New test files. 2017-08-27 Alan Mackenzie Amend the CC Mode macro cache to cope with changes at the macro start Fixes bug #28233. * cc-engine.el (c-invalidate-macro-cache): Fix an off-by-1 error. 2017-08-22 Alan Mackenzie When looking for the end of a declarator, prevent macros fouling up the search The practical implication of this bug was a random jit-lock chunk remaining entirely unfontified. * cc-mode (c-fl-decl-end): If point starts inside a macro, restrict two forward searches to the end of that macro. 2017-07-27 Alan Mackenzie Fix C++ class initializers not always being fontified at mode start. The problem here happened when an "outer list" of declarations moved beyond an "inner list" containing class initializers. These weren't being checked for by the code. Also, fix places in c-get-fontification-context where point is undefined. * cc-fonts.el (c-get-fontification-context): when argument not-front-decl is set, test for class initializers. Also, anchor point in places where it is moved and is otherwise undefined. 2017-07-27 Alan Mackenzie Fix variables in C++ "for" statement not always being fontified. The error happened when there was a comma inside template delimiters. * cc-fonts.el (c-get-fontification-context): In "for" statements, recognise template delimiters containing "," and "&". 2017-07-27 Alan Mackenzie CC Mode: Fix declarator being cut off from terminator by end of jit-lock chunk If a declarator is so cut off, extend the fontification chunk to include it. * cc-mode.el (c-fl-decl-end): New function. (c-change-expand-fl-region, c-context-expand-fl-region): Use the new function. 2017-07-23 Alan Mackenzie Convert CC Mode's c-found-types from an obarray to a hash table. * cc-engine.el (c-clear-found-types): create a hash table rather than an obarray. (c-copy-found-types): Remove. (c-add-type, c-unfind-type, c-check-type, c-list-found-types): Amend to use the new hash table. (c-forward-<>-arglist): Use copy-hash-table rather than c-copy-found-types. 2017-07-13 Alan Mackenzie C++ Mode. Fix anomaly occurring when a ">" is deleted then reinserted. This fontification anomaly happened because after deleting the ">", c-forward-<>-arglist parses the preceding identifier as a putative type but stores it in c-found-types before it becomes clear it is not an unambiguous type. c-forward-<>-arglist fails, leaving the spurious type id in c-found-types. Fix this by "binding" c-found-types "to itself" in c-forward-<>-arglist, and restoring the original value when that function call fails. * cc-engine.el (c-copy-found-types): New function. (c-forward-<>-arglist): Record the original value of c-found-types at the beginning of the function, and restore it at the end on failure. * cc-mode.el (c-unfind-coalesced-tokens): Rewrite more accurately. 2017-07-12 Alan Mackenzie Fix some bugs in c-defun-name. This fixes bug #25623. * cc-cmds.el (c-defun-name): Fix some bugs to do with structs, etc. * cc-mode.el (c-common-init): Set `add-log-current-defun-function'. 2017-07-12 Alan Mackenzie Make prog-mode-map the parent of c-mode-base-map. Fixes bug #26658. * cc-mode.el (top level): Make prog-mode-map the parent of c-mode-base-map if possible. Patch by Vasilij Schneidermann . 2017-07-06 Alan Mackenzie CC Mode: create and use c-set-keymap-parent. * cc-defs.el (c-set-keymap-parent): New macro. * cc-mode.el (top-level): Remove cc-bytecomp-defun for set-keymap-parents. (c-make-inherited-keymap): Use c-set-keymap-parent in place of inline code. 2017-07-02 Alan Mackenzie Fix bug in yesterday's CC Mode commit. * cc-mode.el (c-quoted-number-head-before-point): Check a search has succeded before using the match data. (c-quoted-number-head-before-point, c-quoted-number-head-after-point): Specify that the position of the extremity of the head or tail is in the match data. 2017-07-01 Alan Mackenzie Make C++ digit separators work. Amend the handling of single quotes generally Single quotes, even in strings and comments, are now marked with the "punctuation" syntax-table property, except where they are validly bounding a character literal. They are font locked with font-lock-warning-face except where they are valid. This is done in C, C++, ObjC, and Java Modes. * cc-defs.el (c-clear-char-property-with-value-on-char-function) (c-clear-char-property-with-value-on-char, c-put-char-properties-on-char): New functions/macros. * cc-fonts.el (c-font-lock-invalid-single-quotes): New function. (c-basic-matchers-before): invoke c-font-lock-invalid-single-quotes. * cc-langs.el (c-get-state-before-change-functions): Remove c-before-after-change-digit-quote from wherever it occurs. Insert c-parse-quotes-before-change into the entries for the languages where it is needed. (c-before-font-lock-functions): Remove c-before-after-change-digit-quote from wherever it occurs. Insert c-parse-quotes-after-change into the entries for the languages which need it. (c-has-quoted-numbers): New lang-defconst/-defvar. * cc-mode.el (c-before-after-change-digit-quote): Remove. (c-maybe-quoted-number-head, c-maybe-quoted-number-tail) (c-maybe-quoted-number): New defconsts.

(c--cl-library): New variable. (Top level): Amend the form which requires library cl or cl-lib. (c--mapcan, c--set-difference, c--intersection, c--macroexpand-all) (c--delete-duplicate): Amend to use c--cl-library instead of c--mapcan-status. * cc-engine.el (c-syntactic-skip-backward, c-back-over-compound-identifier): Remove unused local variables. * cc-fonts.el (c-font-lock-declarations): Remove an unused local variable. * cc-langs.el (Top level): Amend to use c--cl-library instead of c--mapcan-status. * cc-styles.el (Top level): Add a cc-bytecomp-defun to try to silence a compiler warning. * 000tests.el (c--string-to-int): New defalias. (cc-test-convert-to-rel-offsets, cc-test-convert-to-abs-offsets): Use c--string-to-int. * comments-6.c: Add emacs-26 into the list of "don't test" versions. 2017-06-16 Alan Mackenzie Ensure C++ initializer lists don't get fontified. * cc-cmds.el (c-block-comment-flag): Move declaration to solve compiler warning. * cc-fonts.el (c-get-fontification-context): Add an extra clause to handle C++ member initialization lists. (c-font-lock-single-decl): New function, extracted from c-font-lock-declarations. (c-font-lock-declarations): Call c-font-lock-single-decl in place of inline code. (c-font-lock-cut-off-declarators): Make more rigorous by calling c-get-fontification-context, c-forward-decl-or-cast-1, and c-font-lock-single-decl in place of rather approximate code. * member-14.{cc,face}: New test files. 2017-06-16 Alan Mackenzie Fix hang in CC Mode when ":" is typed after identifier at EOB. * cc-engine.el (c-forward-declarator): Fix coding error confusing ":" and EOB. 2017-06-15 Alan Mackenzie Create a toggle between block and line comments in CC Mode.

(c-toggle-comment-style): New function. * cc-langs.el (c-block-comment-starter, c-line-comment-starter): Make them c-lang-defvars. (c-block-comment-is-default): New c-lang-defvar. (comment-start, comment-end): Make the default values dependent on c-block-comment-is-default. * cc-mode.el (c-mode-base-map): Define C-c C-k in this map. (c-basic-common-init): Initialize c-block-comment-flag. (c-mode-map, c++-mode-map, objc-mode-map, java-mode-map, idl-mode-map) (pike-mode-map, awk-mode-map): Make entries in these key maps each time the mode is loaded rather than just once per Emacs session. * cc-mode.texi (Comment Commands): Introduce the notion of comment style. (Minor Modes): Define comment style. Describe how comment style influences the information displayed on the modeline. Document c-toggle-comment-style. (FAQ): Add a question about toggling the comment style. 2017-05-30 Alan Mackenzie c-defun-name: Return fully qualified method names when wanted in C++, etc. * cc-cmds.el (c-defun-name): Use c-back-over-compound-identifier in place of c-backward-token-2 near the end of the function. 2017-05-12 Alan Mackenzie Correct earlier change: insert missing `and' form in `c-forward-declarator' * cc-engine (c-forward-declarator): Insert missing `and' form inside a `save-excursion'. 2017-05-12 Alan Mackenzie Fontify C++ for loop variable as variable, even when followed by parentheses In the following: "for (auto *Friend : Class->friends()) {", "Friend" was getting fontified as a function, due to insufficient checking of the tokens between it and "()". * cc-langs.el (c-:-op-cont-tokens, c-:-op-cont-regexp): New lang-consts/vars. * cc-engine.el (c-forward-declarator): After finding a putative declarator's identifier, check for a ":" token inside a for's parentheses, and abort the search for "(" if this is found. * forloop-7.{cc,face}: New test files. 2017-05-07 Alan Mackenzie CC Mode internal cache: Handle a cache pos being inside a two-char construct. Cache c-state-semi-nonlit-pos-cache was failing when a cache position was, e.g., between the two characters of an opening comment "/*", and additionally there were an odd number of quote marks (apostrophes) in the comment. This happened in .../src/xdisp.c in the Emacs master branch around 2017-05-02 at buffer position 615001. * cc-defs.el (c-emacs-features): Repurpose symbol pps-extended-state to mean that there are at least 11 elements in the parser state. * cc-engine.el (c-cache-to-parse-ps-state, c-parse-ps-state-to-cache): Rewrite these to use enhanced cache element list types which indicate potentially being inside two-char constructs. (c-parse-ps-state-below): Rewrite to use the new versions of the above two functions. 2017-04-22 Alan Mackenzie Fix fontification of C++ declaration with type FOO::FOO. * cc-engine.el (c-find-decl-spots): Initialize cfd-top-level properly. (c-forward-decl-or-cast-1): On finding FOO::FOO, check it is followed by "(" before deciding it is a constructor. * cc-fonts.el (c-font-lock-complex-decl-prepare): Negate the result of the c-bs-at-toplevel-p call passed to c-font-lock-declarators (simple bug fix). 2017-04-10 Alan Mackenzie Fix a loop in C Mode caused by inadequate analysis of comments. After M-;, and the insertion of the opening "/*", the CC Mode after-change function got confused, since the new comment opener matched the end of a subsequent comment, but moving back over that comment did not come back to the starting point. Fix this. * cc-engine.el (c-end-of-macro): Add a limit parameter, where point is left if no end-of-macro is found before it. (c-forward-sws): Change the `safe-start' mechanism. Now `safe-start' is non-nil except where we have an unclosed block comment at the end of a macro. This enables us to populate the cache more fully, at the cost of some run time. 2017-03-30 Alan Mackenzie Fix C++ fontification problems 500 bytes after typing a space, and other bugs Also implement the "asymmetric space" rule for fontifying otherwise ambiguous declarations/expressions. * cc-engine.el (c-before-change-check-<>-operators): Don't set c-new-BEG or c-new-END when there is no need. (c-forward-decl-or-cast-1): Add "CASE 17.5" to implement the "asymmetric space" rule. * cc-fonts.el (c-get-fontification-context): New function, extracted from c-font-lock-declarations. Add to this function processing to make `context' 'decl for lines contained within parens when these are also declarations. (c-font-lock-declarations): Call the newly extracted function above in place of inline code. * cc-mode.el (c-fl-decl-start): Set point before calling c-literal-start. * cc-vars.el (c-asymmetry-fontification-flag): New user option. * cc-mode.texi (Misc Font Locking): New node documenting the new "asymmetric fontification" rule, including the variable c-asymmetric-fontification-flag. * decls-10.{cc,face}, decls-13.face, decls-19.face: Edit decls-10.cc to add comment to otherwise puzzling fontifications. Regenerate the three face files to reflect the enhanced fontification this change gives. 2017-03-19 Alan Mackenzie Fix chaotic indentation of C++ lambda. Enhance documentation thereof * cc-engine.el (c-looking-at-inexpr-block): qualify an invocation of c-on-identifier with a check we're not at the _end_ of an identifier. * cc-mode.texi: (Tex title page): Remove @subtitlefont because the perl versions of texi2dvi haven't implemented it. (Syntactic Symbols): Note that `inlambda' is also used in C++ Mode, not just in Pike Mode. (Statement Block Symbols): Add a section illustrating a C++ lambda function. (FAQ): Add a question about "excessive" indentation of the contents of a C++ lambda function, and how to get rid of it. 2017-02-25 Alan Mackenzie Allow for the :: operator in C++ "enum class" declarations. * cc-engine.el (c-backward-typed-enum-colon): Check for "::" * cc-enum-12.{cc,res}: New test files. 2017-02-18 Alan Mackenzie Fix edebug-spec on c-lang-defvar. This allows c-lang-defvars with the symbol 'dont-doc in the place of the optional documentation to be instrumented for edebug. * cc-langs.el (top-level): Amend the edebug-spec for c-lang-defvar. (c-opt-identifier-concat-key, c-decl-prefix-or-start-re): remove redundant 'dont-doc. 2017-02-01 Alan Mackenzie Allow C++ nested brace-list-entries to be better indented. This fixes bug #24431. The key change of this bug fix is correctly analyzing nested brace lists when the opening element stands on the same line as both its introductory brace and an enclosing parameter list parenthesis. * cc-align.el (c-lineup-under-anchor): New line-up function. * cc-engine.el (c-looking-at-or-maybe-in-bracelist): Accept the presence of exactly an identifier between an open parenthesis and an open brace as evidence of the brace starting a brace list. (c-looking-at-statement-block): New function, extracted from c-looking-at-inexpr-block. Enhance it to analyze inner blocks recursively when needed. (c-looking-at-inexpr-block): Extract new function (see above) and call it. (c-add-stmt-syntax): Enhance, with new &optional parameter, to supply the prime syntactic symbol with a fixed anchor point. When this is used, restrict all added syntactic symbols to those having an anchor point on the same line. Add, in addition to the current additional symbols, c-brace-list-entry when needed; use c-looking-at-statement-block to determine the latter. (c-guess-basic-syntax, CASE 9D): Use c-add-stmt-syntax rather than just c-add-syntax, to assemble the syntactic context of a 'brace-list-entry, thus getting, possibly, several accompanying syntactic entries. * cc-styles.el (c-style-alist, "gnu" style): New entry for 'brace-list-intro, namely c-lineup-arglist-intro-after-paren. * cc-vars.el (c-offsets-alist): Change the factory default offset for 'brace-list-entry from 0 to c-lineup-under-anchor. * cc-mode.texi (Syntactic Symbols): Amend the definition of brace-list-intro. (Brace List Symbols): Amend the example to show the new analysis of brace lists when the first element comes on the same line as the opening brace. (Misc Line-Up): Document the new line-up function c-lineup-under-anchor. * 000tests.el (cc-test-teststyle): Change the offset for 'brace-list-entry from 0 to c-lineup-under-anchor. * bracelist-2.res, bracelist-25.res, bracelist-8.res, bracelist-9.res, class-21.res: regenerate to incorporate new analysis of brace lists. 2017-01-21 Alan Mackenzie Fix low-level handling of (big) C macros. In particular, ensure that a comment detected by its syntax is not a CPP construct marked with generic comment delimiter syntax-table text properties. * cc-engine.el (c-beginning-of-macro, c-end-of-macro): Set c-macro-cache-syntactic to nil when the cached macro changes. (c-syntactic-end-of-macro, c-no-comment-end-of-macro) (c-state-semi-pp-to-literal, c-state-full-pp-to-literal) (c-state-pp-to-literal, c-parse-ps-state-to-cache) (c-state-cache-non-literal-place, c-literal-limits, c-literal-start) (c-determine-limit): When checking a parse syntax for a comment, check that we're not in a CPP construct marked by syntax-table generic comment delimiter text property. (c-state-pp-to-literal): Change from a defsubst to a defun. * cc-mode.el (c-neutralize-syntax-in-and-mark-CPP): Check a parse syntax as described above under cc-engine.el. 2017-01-14 Alan Mackenzie Correct c-parse-state-get-strategy for moving HERE backward into a macro. * cc-engine.el (c-parse-state-get-strategy): When HERE is below its previous value, we chose strategy 'forward, and the new HERE is in a (different) macro, ensure the returned START-POINT is not above the start of the macro. 2017-01-10 Alan Mackenzie Handle syntactic WS cache properties more accurately at buffer changes. This fixes bug #25362. * cc-engine.el (c-sws-lit-type, c-sws-lit-limits) (c-invalidate-sws-region-before, c-invalidate-sws-region-after-del) (c-invalidate-sws-region-after-ins): New variables and functions. (c-invalidate-sws-region-after): Change from a defsubst to a defun. Also pass it the standard OLD-LEN argument. Call both c-invalidate-sws-region-after-{ins,del} to check for "dangerous" WS cache properties. * cc-langs.el (c-block-comment-ender-regexp): New language variable. * cc-mode.el (c-before-change): Call c-invalidate-sws-region-before. (c-after-change): Pass old-len to c-invalidate-sws-region-after. 2016-12-31 Alan Mackenzie Fix edebug spec for cc-eval-when-compile to allow for instrumenting defuns * cc-defs.el: Correct the edebug spec for cc-eval-when-compile from t to (&rest def-form) so that it will insert an edebug-enter into the instrumented form, thus allowing functions containing it to be debugged without the instrumentation throwing errors. 2016-12-30 Alan Mackenzie CC Mode: Fix the fontification of a spuriously recognised enum member. The "enum" was in an argument list, but triggered the fontification of a following identifier in the function block as though it were in an enum declaration. * cc-fonts.el (c-font-lock-enum-body): New function. (c-basic-matchers-after): Replace the inline stanza for enum elements with a call to c-font-lock-enum-body. * cc-langs.el (c-enum-clause-introduction-re): New language variable. * enum-11.{c,face}: New test files. 2016-12-29 Alan Mackenzie Partially correct fontification of "(b*3)", and the like, in C++ Mode This problem is caused by the fundamental ambiguity in C++ between argument declarations and initialisation clauses. * cc-fonts.el (c-font-lock-declarations): If we have an open paren preceded by an arithmetic operator, we give this the context nil, not 'arglist. * cc-langs.el (c-arithmetic-operators, c-arithmetic-op-regexp): New lang consts and vars. * decls-42.{cc,face}: New test files. 2016-10-09 Alan Mackenzie CC Mode manual: remove reference to former Emacs variable last-command-char * cc-mode.texi (Hanging Semicolons and Commas): Replace reference to variable last-command-char by one to macro c-last-command-char. 2016-09-22 Alan Mackenzie * cc-engine.el (c-forward-decl-or-cast-1): Fix coding error 2016-09-16 Alan Mackenzie C Mode: Fix mis-fontification of macro invocation as function declaration This happened with a macro invocation which was followed by a statement block in braces. * cc-engine.el (c-forward-decl-or-cast-1): CASE 11: distinguish between contexts nil and top, being less permissive in the former case. (c-just-after-func-arglist-p): call c-forward-decl-or-cast-1 with context top. * decls-41.{c,face}: New test files. 2016-09-11 Alan Mackenzie Correctly fontify C++ direct initializations with parens inside functions Or, more clearly, when something looks like a function declaration and it's inside a function, fontify it as a direct initialization. For this purpose, introduce a "brace stack" for each buffer, where an entry on the brace stack states how deeply nested a particular position is inside braces inside a "top level", which includes classes and namespaces. Also introduce a new "context", "top", with which c-font-lock-declarations signals to c-forward-decl-or-cast-1 that point is at the top level. * cc-langs.el (c-get-state-before-change-functions): add c-truncate-bs-cache. (c-flat-decl-block-kwds, c-brace-stack-thing-key, c-brace-stack-no-semi-key) (c-type-decl-operator-prefix-key): new language constants/variables. * cc-engine.el (c-bs-interval, c-bs-cache, c-bs-cache-limit, c-bs-prev-pos) (c-bs-prev-stack): New mostly local variables for the brace stack cache. (c-init-bs-cache, c-truncate-bs-cache, c-truncate-bs-cache, c-brace-stack-at) (c-bs-at-toplevel-p): New functions which manipulate the brace stack (cache). (c-find-decl-prefix-search): Keep track of whether we're at top level. (c-find-decl-spots): New local variable cfd-top-level which records what it says. On calling cfd-fun, pass cfd-top-level as an additional argument. (c-forward-declarator): Add new element DECORATED to the result list. Set it to non-nil when a match for c-type-decl-operator-prefix-key is found. (c-forward-decl-or-cast-1): Handle the newly introduced context "top". Introduce "CASE 9.5", which recognizes direct initializations. * cc-fonts.el (c-font-lock-complex-decl-prepare, c-font-lock-enum-tail) (c-font-lock-cut-off-declarators, c-font-lock-enclosing-decls) (c-simple-decl-matchers, c-basic-matchers-after): Add appropriate `not-top' argument to calls to c-font-lock-declarators. (c-font-lock-declarators): Additional parameter `not-top'. Use not-top to participate in the decision whether to fontify an identifier as a function or a variable. (c-font-lock-declarations): The internal lambda function takes an additional argument `toplev' from c-find-decl-spots, which it uses in determining the "context" of a declaration. Add appropriate `not-top' argument to calls to c-font-lock-declarators. (c-font-lock-objc-methods): Add extra parameter to internal lambda function, like for c-font-lock-declarators. * cc-mode.el (c-basic-common-init): Initialize the brace stack cache. * decls-28.face, templates-12.face: Regenerate for changed fontification. * decls-38.{cc,face}, decls-39.{cc,face}, decls-40.{cc-face}: New test files. 2016-09-06 Alan Mackenzie * cc-engine.el (c-syntactic-re-search-forward): Fix coding error 2016-09-06 Alan Mackenzie New options for handling of literals in c-syntactic-re-search-forward * cc-engine.el (c-syntactic-re-search-forward): `noerror' can be given the values `before-literal' and `after-literal', so that when a search fails, and the `bound' is inside a literal, point is left respectively before or after that literal. 2016-09-01 Alan Mackenzie Fix c-declaration-limits to return correct limits in all cases. This function is the guts of c-indent-defun and c-mark-function. In particular, when c-defun-tactic is nil, return a correct value rather than always nil, and when it's 'go-outward, go through an intricate algorithm to determine the requisite narrowing before the "top-level" defuns go to work. * cc-cmds.el (c-narrow-to-most-enclosing-decl-block): Enhance to take additional optional parameter LEVEL, saying how many enclosing levels of decl-block to narrow to. (c-declaration-limits): Introduce algorithm to determine narrowing. Use c-where-wrt-to-brace-block to determine whether to go back to BOD to determine lower bound. 2016-08-30 Alan Mackenzie Correctly analyze C++ list initialization in member init areas. * cc-engine.el (c-back-over-list-of-member-inits): Remove a superfluous call to c-backward-syntactic-ws. (c-looking-at-or-maybe-in-bracelist): Change calling convention, so that it reports encountering the Java "new" keyword. Add, as an alternative, a check that we can move back over member initializations, and handle this as finding a brace block. (c-looking-at-special-brace-list, c-guess-continued-construct): Adapt to the new calling convention of c-looking-at-or-maybe-in-bracelist. (c-guess-basic-syntax, CASE 5A.3): Replace lots of inline ad-hoc code with calls to c-backward-over-enum-header and c-looking-at-or-maybe-in-bracelist, using the extra info from the value of that function to generate a topmost-into-cont element where needed (in Java). * cc-fonts.el (c-font-lock-declarations): Adapt to the new calling convention of c-looking-at-or-maybe-in-bracelist. * cc-mode.el (c-fl-decl-start): Adapt to the new calling convention of c-looking-at-or-maybe-in-bracelist. * bracelist-25.res. Newly generated for the newly correct analysis. * enum-7.res. Newly generated for the newly correct analysis. 2016-08-27 Alan Mackenzie Handle the C++ "identifiers" "final" and "override" correctly. This fixes bug #24319, allowing destructors affixed with these identifiers to be correctly fontified. * cc-engine.el (c-forward-type, c-forward-decl-or-cast-1): After reaching the "end" of a type expression, skip over any occurrences of c-type-decl-suffix-ws-ids-key. * cc-langs.el (c-type-modifier-kwds): Remove "override" and "final" from the C++ value. (c-type-decl-suffix-ws-ids-kwds, c-type-decl-suffix-ws-ids-key): New lang constants/variables for "final" and "override". * class-34.{cc,face}: New test files. 2016-08-27 Alan Mackenzie Handle template delimiters in C++ member init constructs. * cc-engine.el (c-back-over-list-of-member-inits): Add handling for "<....>"s. * class-33.{cc,res}: New test files. 2016-08-26 Alan Mackenzie Make minor amendments after release 5.33 * cc-mode.texi: Update version number to 5.33. * changes-533.php: Amend the address to download from. * compat.php: Amend the list of compatible versions of [X]Emacs. * hgaccess.php: Update version number to 5.33. 2016-08-25 Alan Mackenzie * Release 5.33 * cc-*.el, cc-mode.texi: Update copyright statements. * cc-defs.el (c-version): Update to 5.33 * ANNOUNCEMENT, README: Update to version 5.33. * MANIFEST: Removal two obsolete .el files from the list. * NEWS: Insert a summary of new 5.33 features. * ChangeLog: Add entries for all changes since release 5.32.5. * Changelinks.h: Add a line for changes-533.php. * changes-533.php: New file, web version of new information in NEWS. * compat.php: Update to the [X]Emacs versions compatible with release 5.33. * index.php, release.php: Update version numbers. * links.h: Update version numbers. Remove the obsolete references to CVS stuff. 2016-08-25 Alan Mackenzie Fix an infinite loop in C++ Mode when we have "{ .... [ .... }" * cc-fonts.el (c-font-lock-c++-lambda-captures): In the inner `while' form's condition, check for "\\s)" rather than merely "\\]", so that the loop won't hang at a "terminating" paren of a different type (due to the c-syntactic-re-search-forward at the end of the loop stopping at such characters). 2016-08-24 Alan Mackenzie Analyze and fontify correctly a C++ `enum' with colon, but lacking a tag. * cc-engine.el (c-backward-typed-enum-colon): Check for "enum" directly preceding the colon, and handle it. * enum-10.{cc,res,face}: New test files. 2016-08-21 Alan Mackenzie Adapt CC Mode for C++11 uniform initialization. For fontification, introduce a new "context", 'non-decl, to be used for brace lists; also a new value for the property 'c-type, called 'c-not-decl. * cc-engine.el (c-back-over-compound-identifier): Check that an ostensible symbol we're going to move over isn't a keyword. (c-forward-decl-or-cast-1): CASE 1: Where we have two consecutive identifiers (hence a declaration), and an unmatched open paren, perform c-fdoc-shift-type-backwards to recognize the partial construct correctly. Whilst checking a type decl expression, check for and handle C++11's "copy initialization", where we have (). Recognize (... (where the paren is unclosed) as a declaration. (c-looking-at-or-maybe-in-bracelist): New function, extracted from c-inside-bracelist-p. Recognize as bracelists "{"s which are preceded by valid tokens other than "=". Recognize a bracelist when preceded by a template declaration. (c-inside-bracelist-p): Call c-looking-at-or-maybe-in-bracelist in place of much inline code. (c-looking-at-inexpr-block): Amend so that it won't wrongly recognise an initialization starting "({" as an in-expression block, by checking for semicolons, as opposed to commas, separating elements inside it. (c-guess-continued-construct): (CASE B-2): Recognize a brace-list-open by calling c-looking-at-or-maybe-in-bracelist rather than checking for a preceding "=". (CASE B-5): New code to recognize new construct "return { ...}". (c-guess-basic-syntax): (CASE 5A.3): Additionally recognize a "{" preceded by "return", or "{" preceded by as a bracelist. * cc-fonts.el (c-font-lock-declarations): Recognize brace lists, giving them `context' 'non-decl. Pass over elements of one by regexp search for "," rather than calling c-forward-decl-or-cast-1. * cc-langs.el (c-return-kwds, c-return-key): New lang constants/variables to recognize "return". (c-pre-id-bracelist-key): New lang constant/variable to recognize tokens which, when preceding an identifier followed by a brace, signify the brace as a bracelist. * cc-mode.el (c-fl-decl-start): When searching outwards for the start of a "local" declaration, move out from an enclosing brace when that is the start of a brace list. * bracelist-25.{cc,face,res}: New test files. 2016-08-20 Alan Mackenzie * cc-defs.el (c-safe-scan-lists): Resolve overelaborate "nil" 2016-08-20 Alan Mackenzie In c-\(go-\)?-\(up-\|down-\)?list-\(forward\|backward\) check limit isn't nil Check the limit both at macro expansion time (for a hard coded nil) and at run time in the generated code. Tidy up these macros generally. * cc-defs.el (c-safe-scan-lists): Check `limit' is present and not identically nil before generating a narrow-to-region call. Generate code to check `limit' is not nil at run time. (c-go-list-forward, c-go-list-backward): Remove the generation of redundant narrow-to-region, instead calling c-safe-scan-lists directly. (c-go-up-list-forward, c-go-up-list-backward, c-go-down-list-forward) (c-go-down-list-backward): Invoke the corresponding macros without the "go-" to determine the destination position instead of generating a redundant narrow-to-region. 2016-08-17 Alan Mackenzie Fontify constructs following "::" in C++ argument lists correctly - part 2.

For AWK Mode. 2008-11-07 Alan Mackenzie * tests/000tests.el (cc-test-extend-faces): When two faces aren't distinct, display a `message' rather than throwing an `error', a barely understood kludge to allow interactive use of 000tests.el.

Also enhance the commenting significantly. 2008-04-17 Alan Mackenzie * cc-langs.el (c-type-decl-prefix-key): C++ bit: move "\(const\|throw\|volatile\)\>" nearer the start of the regexp, so that these keywords aren't wrongly matched as identifiers. * cc-fonts.el (c-font-lock-declarators): In (match-beginning 2), "2" -> "3", corresponding to the change in c-type-decl-prefix-key.

Do this by calling `hack-local-variables' a second time. * cc-vars.el: Add language specific customization widgets for AWK to c-doc-comment-style, c-require-final-newline and c-default-style. Add a defcustom for awk-mode-hook. Give c-syntactic-element and c-syntactic-context doc-strings by directly setting their `variable-documentation' propery.

Complete several cross references with their fifth parameter (the name of the printed manual). "Indentation Commands": Tidy up `c-indent-command', putting the variables `c-tab-always-indent' and `c-insert-tab-function' inside its description. Inserted some "printed manual names" into cross references where they were missing. Move description of `indent-for-comment' into ... "Comment Command": A new @section under "Commands"; it contains the description of `indent-for-comment'; this was taken out of "Indentation Commands".

Make sure there's a blank line at the top of each node. * cc-mode.texi: "Indentation Engine Basics": (i) Rearrange the paragraphs more logically; (ii) make @dfn's out of "syntactic symbol", "anchor position" and "offset(s)". (iii) Make an @enumeration out of the two-step indentation process. (iv) Add a paragraph motivating c-syntactic-indentation, complete with a reference to "Config Strategies". 2005-10-02 Alan Mackenzie * cc-mode.texi: "Custom Line-Up": (i) Increase the concision of the page. (ii) Comment out the example. (Maybe this should go into its own @subsection.) (iii) Specify precisely the conventions for a line-up function, in particular, that point may not be moved. (iv) Add in the suggestion that c-special-indent-hook may sometimes be a better idea than line-up functions. There are minor consequential changes on other pages. 2005-09-18 Alan Mackenzie * cc-mode.texi: (i) Partition the over-large @section "Line-Up Functions". (ii) Expand the description of c-special-indent-hook. (iii) Add cross references between "Other Indentation" and "Custom Line-up", emphasizing that c-special-indent-hook functions and line-up functions are alternatives. 2005-09-17 Alan Mackenzie * cc-styles.el: Amend the doc-string of c-set-style, in reponse to a report from Joseph Kiniry that it was difficult to understand. 2005-09-11 Martin Stjernholm * cc-engine.el (c-on-identifier): Fixed bug when at the first char of an identifier. * cc-engine.el (c-on-identifier): Handle the "operator +" syntax in C++. 2005-09-09 Alan Mackenzie * cc-mode.texi ("Syntactic Analysis"): Minor amendments. ("Syntactic Symbols"): Partition this monster into a section with thirteen subsections, each of which (more or less) illustrates a coherent grouping of symbols. Replace the spurious references to substatement-block-intro with statement-block-intro. Add @ssindex entries for those symbols missing them. 2005-09-08 Alan Mackenzie * cc-mode.texi: Some general tidying up and clarification. Also: (Hooks): mention c-special-indent-hook (FAQ): Commented out the question about M-[ae] going into blocks. 2005-08-29 Alan Mackenzie * cc-mode.texi: 55 Changes, great and small. Most of them are minor linguistic improvements, clarifications, adding xrefs, bug fixes, or the like, but there are also several more notable changes: (i) "Config Strategies": State which setting takes precedence when conflicting settings are made (e.g. both in a style and in a hook). (ii) "Config Strategies": Add a bit about "File Styles". (iii) "File Styles": Fleshed out this chapter quite a bit. (iv) "Mode Initialization": Removed this embryonic node (which was far from complete or useful) and all references to it. 2005-08-18 Alan Mackenzie * cc-cmds.el (c-mask-paragraph): correct, so that auto-fill doesn't split a c-comment's last word from a hanging "*/" when a space is typed between them after fill-column. cc-defs.el: New macro c-delete-and-extract-region. 2005-06-24 Alan Mackenzie * cc-styles.el (c-set-style, c-setup-paragraph-variables): Abort the command if we're not in a CC Mode buffer. 2005-06-13 Alan Mackenzie * cc-align.el (c-lineup-C-comments): Correct indentation with blank comment-prefix, and a blank line as the comment's second line. 2005-05-22 Martin Stjernholm * cc-fonts.el (c-cpp-matchers, c-basic-matchers-before): Incorporated the patterns added in the Emacs development branch for the new Emacs 22 face `font-lock-negation-char-face'. * cc-fonts.el (c-invalid-face-name): Use "red1" instead of "red" since it stands out better in xterms and DOS terminals. * cc-engine.el (c-literal-faces): Added `font-lock-comment-delimiter-face' which is new in Emacs 22. * cc-fonts.el (c-font-lock-declarators): Fixed bug where the point could go past the limit in decoration level 2, thereby causing errors during interactive fontification. 2005-05-08 Alan Mackenzie * cc-mode.texi: Add documention for the new electric minor mode and finish that for clean-up comment-close-slash. Tidy up the structure a bit, make some minor linguistic improvements. In detail: Change "Clean-ups" from being a section of "Custom auto-newlines) to being its own section, since it documents some stuff which is independent of auto-nelines. Change "Auto-newlines" and "Hungry WS Deletion" from being subsections of "Minor Modes" to their own sections, since they're to important to hide. Move "Electric Keys" alongside them, since it now bears the same relationship to "Minor Modes" as "Auto-newlines" and "Hungry WS .." do. "Indentation Commands": Add a convenience description of standard (X)Emacs C-j. "Minor Modes": (i) Document the new "electric minor mode" with toggle C-c C-l, and the coupling between it and c-toggle-auto-newline. (ii) Remove the description of the defunct `c-toggle-auto-hungry-state'. (iii) Update the description of the modeline flags. (iv) Recast the node considerably in the process. "Electric Keys and Keywords": (i) Add a note that electric minor mode needs to be enabled for (most of) the stuff here to work. (ii) Mention the new clean-up comment-close-slash. (iii) Note the electric actions which don't need electric minor mode to be enabled. "Sample .emacs File": Replace c-toggle-auto-hungry-state with c-toggle-\(auto-newline\|hungry-state\). "FAQ": Add an entry "How do I stop my code jumping all over the place when I type?". 2005-05-07 Alan Mackenzie * cc-cmds.el: Correct previous patch to c-toggle-auto-newline. * cc-mode.texi: Document the new clean-up `comment-close-slash'. * cc-cmds.el: Make C-c C-a (`c-toggle-auto-newline') forcibly enable c-electric-flag. 2005-05-06 Alan Mackenzie * cc-vars.el, cc-cmds.el: New clean-up `comment-close-slash' on c-electric-slash: if enabled, typing `/' just after the comment-prefix of a C-style comment will close that comment. 2005-05-05 Alan Mackenzie * cc-mode.texi: Sync with Lute Kamstra's patch from emacs-devel to prevent a superfluous cc-mode.ss index file being built with texi2dvi. 2005-05-01 Martin Stjernholm * cc-fonts.el (c-basic-matchers-before, c-complex-decl-matchers): Fixed the "not-arrow-prefix" regexp used in Pike. * cc-langs.el (c-other-op-syntax-tokens): Only C++ has digraphs. 2005-04-29 Alan Mackenzie * cc-mode.texi: Resolve some CVS conflict markers. * cc-mode.texi: Custom Filling and Breaking: State that c-comment-prefix regexp can be an association list. 2005-04-11 Martin Stjernholm * cc-fonts.el, cc-langs.el, cc-engine.el (c-cpp-message-directives, c-cpp-include-directives, c-opt-cpp-macro-define, c-opt-cpp-macro-define-start, c-cpp-expr-directives): Introduced new language constants to control cpp syntax in a cleaner way. (c-cpp-expr-functions): Renamed from c-cpp-defined-fns. (c-cpp-matchers, c-forward-to-cpp-define-body): Use them. 2005-04-10 Martin Stjernholm * cc-mode.el (c-make-inherited-keymap): Fixed cc-bytecomp bug when the file is evaluated interactively. * cc-langs.el, cc-fonts.el (c-string-escaped-newlines, c-multiline-string-start-char): New language constants and variables to specify how newlines in string literals work. (c-font-lock-invalid-string): Use them. * cc-mode.texi: Removed hint that the one-liner-defun cleanup only would be useful/relevant in AWK mode. * cc-cmds.el (c-try-one-liner): Robustness fix if an unbalanced close brace is entered. Optimization by avoiding going back over arbitrarily large blocks. Removed hints that this function only would be relevant/useful in AWK. (c-electric-brace): Indent syntactically after the cleanups since lineup functions might do it differently then. * cc-engine.el, cc-langs.el (c-opt-op-identifier-prefix): New language constant and variable. (c-just-after-func-arglist-p, c-after-special-operator-id, c-search-decl-header-end, c-inside-bracelist-p): Use it. 2005-02-14 Kevin Ryde : * cc-align.el (c-lineup-argcont): Ignore conses for {} pairs from c-parse-state, to avoid a lisp error (on bad code). 2005-04-09 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Handle operator declarations somewhat better in C++. * cc-align.el, cc-engine.el (c-after-special-operator-id): New helper to handle C++ operator identifiers. (c-lineup-topmost-intro-cont, c-just-after-func-arglist-p, c-guess-basic-syntax): Handle C++ operator identifiers in declarations. * cc-langs.el (c-assignment-operators): Added the trigraph version of ^= too. * cc-langs.el (c-assignment-operators): Added the trigraph version of |= in C++. 2005-04-08 Alan Mackenzie * cc-mode.texi: "Advanced Customizations": Finally remove the vestiges of this chapter. Resolve three other minor FIXMEs. 2005-04-03 Martin Stjernholm * cc-fonts.el (c-font-lock-declarators): Handle `c-decl-hangon-kwds' after the identifier name. * cc-engine.el (c-guess-basic-syntax): When deciding whether an arglist is "nonempty", ignore a comment after the open paren if it isn't followed by a non-comment token on the same line. * cc-engine.el (c-guess-basic-syntax): Case 4: Enable heuristics below the point to cope with classes inside special brace lists in Pike. 2005-04-03 Alan Mackenzie * cc-mode.texi: Correct a typo in the sourceforge CVS URL. * cc-mode.texi: Add a statement that the manual is GPL'd. Add a pointer to the manual's source at sourceforge. 2005-04-01 Alan Mackenzie * cc-cmds.el: Amend c-point-syntax to handle macros. 2005-03-29 Martin Stjernholm * cc-guess.el (cc-guess-install): New function to install an already guessed style in another buffer. 2005-02-14 Kevin Ryde * cc-mode.texi (File Styles): Cross reference emacs file local variables, correction to grammatical typo. 2005-03-20 Martin Stjernholm * cc-guess.el: Improvement contributed by Masatake YAMATO: Frequency is now taken into account to make a better guess. (cc-guess-region): Inverted the RESET argument to make it more convenient. The guessed style is also merged into `c-offsets-alist' right away. (cc-guess, cc-guess-view-style): New functions. 2005-03-19 Martin Stjernholm * cc-defs.el (c-tentative-buffer-changes): No longer sets `inhibit-read-only' - `c-save-buffer-state' should be used anyway if the change always is undone. 2005-03-12 Alan Mackenzie Implement togglable electricity: * cc-defs.el: Enhance c-save-buffer-state's doc-string, saying when it should be used. * cc-engine.el: Add the new buffer-local variable, c-electric-flag. * cc-langs.el: Change the name of c-toggle-auto-state to c-toggle-auto-newline. * cc-mode.el: Rename c-toggle-auto-state to c-toggle-auto-newline. Remove the binding for c-toggle-auto-hungry-state. Add the binding C-c C-l for the new c-toggle-electric-state. * cc-vars.el: Make c-syntactic-indentation buffer local. * cc-cmds.el: Add `c-bytecomp-defun's for c-\(forward\|backward\)-subword. (c-update-modeline): Add the new modeline flag `l' for `c-electric-flag'. Make the auto-newline flag `a' dependent on `l'. (c-toggle-auto-state): Rename it to `c-toggle-auto-newline'. Make the old name an alias of the new name. (c-toggle-auto-hungry-state): Removed. (c-toggle-electric-state): New function. c-electric-\(pound\|brace\|slash\|star\|semi&comma\|colon\|lt-gt\|paren\|continued-statement\): Adapt these functions to do electric things only when c-electric-flag is non-nil. (c-point-syntax, c-brace-newlines, c-try-oneliner): Extract these new functions from c-electric-brace. (c-point-syntax): Add a check for "virtual semicolons" in AWK mode, so that the tentative extra newline doesn't change the syntax of the following brace. (c-electric-brace): restructure by extracting the above functions. Tidy up the coding somewhat. (c-electric-semi&comma, c-electric-colon, c-electric-paren): restructure a bit. * cc-mode.texi: "Electric Keys": Amend description of `<' and `>': they are also electric when they are template brackets. "Other Commands": Add an entry for the standard Emacs command `comment-region' which has CC Mode binding C-c C-c. "Custom Filling and Breaking": Purge the description of `c-comment-prefix-regexp' of confusing gobbledygook. 2005-03-02 Alan Mackenzie * cc-mode.texi: "Filling and Breaking": Add a cross reference to "Custom Filling and Breaking". Several minor amendments. 2005-02-01 Alan Mackenzie * cc-mode.texi: Merge the changes made on branch texi-0-1 back to HEAD. 2005-01-31 Alan Mackenzie * cc-mode.texi: "Overview": Get rid of reference to "AWK" section; "Sample .emacs FILE": Put key bindings into c-initialization-hook; Move the c-add-style call from out of the c-mode-hook. 2004-12-19 Alan Mackenzie * cc-mode.texi: In the GNU/XEmacs conditional things, replace "X" by "XEMACS" for clarity. Rename the chapter "Indentation Engine" to "Indentation Engine Basics". "Indentation Commands": Add stuff about macros (taken from the old "Macro Handling" chapter). "Other Commands": Move the description of "c-backslash-region" into here. Rename "Macro Handling" to "Custom Macros", having moved the stuff other than customization to other chapters. * cc-vars.el: Remove the erroneous (doubly inserted) patch from yesterday. 2004-12-18 Martin Stjernholm * cc-cmds.el (c-show-syntactic-information): Show the anchor position(s) using faces. Thanks to Masatake YAMATO for the idea. * cc-mode.el, cc-cmds.el, cc-defs.el, cc-engine.el (c-submode-indicators): Changed name from `c-auto-hungry-string' since it's now used to track another submode. (c-update-modeline): Converted to function and extended to check `c-subword-move-mode'. (c-forward-into-nomenclature, c-backward-into-nomenclature): Converted to compat aliases for `c-forward-subword' and `c-backward-subword'. * cc-subword.el: New functions and minor mode to handle SillyCapsedStyleIndentifiers, contributed by Masatake YAMATO: (c-forward-subword, c-backward-subword, c-mark-subword, c-kill-subword, c-backward-kill-subword, c-transpose-subwords, c-capitalize-subword, c-downcase-subword, c-upcase-subword): Functions corresponding to the standard word handling functions. (c-subword-move-mode): Minor mode that replaces all the standard word handling functions with their subword equivalences. 2004-12-17 Alan Mackenzie * cc-vars.el (c-cleanup-list): Insert a customization entry for one-liner-defun. 2004-12-12 Alan Mackenzie * cc-defs.el: Give c-tentative-buffer-changes its own name in its def-edebug-spec. * cc-cmds.el (c-electric-brace): Make the one-liner-defun clean-up work with empty-defun-braces. o-l-d now compacts space before a comment, if this will make things fit on one line. 2004-12-05 Alan Mackenzie * cc-mode.texi: "AWK Mode Defuns": Removed this subsection, transferring its contents to "Movement Commands" "Movement Commands": Condensed the separate descriptions of complementary -backward-* and -forward-* commands into joint descriptions. 2004-12-04 Alan Mackenzie * cc-mode.texi: "Introduction": Integrated Alan more tightly into CC-Mode. ;-) "Overview": New chapter describing the structure of the manual. "Other Commands": Added a description of c-macro-expand. "Built-in Styles": Added a description of the new "awk" style. "Custom Braces" and "Hanging Semicolons and Commas": Specify the meaning of point in action functions, and that is must be preserved. "Clean-ups": Document the new clean-up one-liner-defun and associated variable c-max-one-liner-length. "Customizing Indentation" is now its own chapter rather than being a section of "Indentation Engine". "AWK Mode: Removed the entire chapter, moving the two remaining useful sections to "Font Locking" and "Movement Commands". Added/Moved lots of index entries. 2004-11-29 Alan Mackenzie * cc-mode.el: Add a fourth parameter `t' to the awk-mode autoload, so that it is interactive, hence can be found by M-x awk-mode whilst cc-mode is yet to be loaded. Reported by Glenn Morris . 2004-11-28 Alan Mackenzie Introduce an "awk" style, mainly for auto-newline and clean-ups. * cc-align.el: new function c-snug-1line-defun-close * cc-cmds.el: In c-electric-brace, add code for new clean-up one-liner-defun. * cc-styles.el: Add the new "awk" style. * cc-vars.el: Add description of one-liner-defun to c-cleanup-list's doc-string. New user options, c-max-one-liner-length. In c-default-style, set the default style for AWK to "awk". 2004-11-28 Martin Stjernholm * cc-mode.el, cc-styles.el (c-run-mode-hooks): New helper macro to make use of `run-mode-hooks' which has been added in Emacs 21.1. (c-mode, c++-mode, objc-mode, java-mode, idl-mode, pike-mode, awk-mode): Use it. (make-local-hook): Suppress warning about obsoleteness which has been added in Emacs 21.1. 2004-11-07 Martin Stjernholm * cc-engine.el (c-forward-label): Fixed fontification of macros inside labels. 2004-11-04 Alan Mackenzie * cc-mode.texi: (i) Some general tidying up, remove @ignore sections, etc. (ii) Firm up the mechanism for generating @xrefs to the Emacs/Xemacs manual and the Elisp/Lispref manual. There are now four macros, @emacsman{}, @lispref{}, @emacsmantitle{}, @lispreftitle{} which generate the filenames and titles (for the printed versions) of the manuals pertinent to Emacs or XEmacs, depending on whether the makeinfo variable `X' is defined or not. The titles were taken from the @settitle lines in the source files of the four manuals. In the process, the title "The Emacs Editor" has been amended to "GNU Emacs Manual". 2004-10-16 Alan Mackenzie * cc-mode.texi: Much general tidying up of the wording. "Auto-newlines" (i) Add a note that c-electric-* only do their stuff when last on line. (ii) State that a `before' auto-newline is never added if the `{' etc. is "already on a newline". (iii) Replace the statement of where auto-newlines go by default (it was wrong and oversimplified) by a statement that the style system does the configuration most of the time. "Custom Auto-newlines" (i) Make the page what it says it is, removing the stuff which is now in "Commands". (ii) Add a @dfn{} for "hang", and "hanging on the left/right". (iii) "Hanging Braces" (i) Insert an @enumerated section describing the algorithm. (ii) Insert a more robust description of c-hanging-braces-alist. (iii) "Hanging Colons" (i) Update this page to mirror "Hanging Braces". (ii) State that the default action (if no alist entry) is to add no newlines. "Custom Semis and Commas" (i) Add clarification that criteria functions don't themselves add newlines. (ii) State that NLs never get added _before_ a `;' or `,'. (iii) "Clean-ups" (i) Give an actual definition of "Clean-up" for the @dfn{}. ;-) Moved the @section "Custom Brace and Colon Hanging" away from "Advanced Customizations" to underneath "Hanging Braces", removing the spurious "and Colons" from its name. Moved the contents of the @section "Customizing Semicolons and Commas" away from "Advanced Customizations" and inserted them into "Hanging Semicolons and Commas" (which previously had only a pointer into the CSaC node). "Advanced Customization" is now almost content free. Add Experimental macros for "Emacs"/"XEmacs" and "Elisp"/"Lispref", in the hope they might enable a better XEmacs version of the manual. 2004-10-07 Martin Stjernholm * cc-cmds.el, cc-engine.el, cc-align.el (c-append-backslashes-forward, c-delete-backslashes-forward, c-find-decl-spots, c-semi&comma-no-newlines-before-nonblanks): Compensate for return value from `forward-line' when it has moved but not to a different line due to eob. 2004-10-01 Martin Stjernholm * cc-engine.el (c-looking-at-bos): Obsoleted in favor of `c-at-statement-start-p' and `c-at-expression-start-p'. * cc-defs.el (c-tnt-chng-record-state): Don't signal an error if the mark isn't set. * cc-engine.el (c-guess-basic-syntax): Fixed anchoring in `objc-method-intro' and `objc-method-args-cont'. * cc-engine.el (c-guess-continued-construct, c-guess-basic-syntax): Use `c-forward-decl-or-cast-1' to more accurately detect functions inside functions. 2004-09-30 Alan Mackenzie * cc-mode.texi: Reorder the chapters a bit on the principle "Most basic earliest": Move "Font locking" with contents to just after "Commands". Move "Indentation Engine" with contents to just after "Custom Filling and Breaking". Move "Custom Filling and Line Breaking" to before "Custom Auto-Newlines". 2004-09-26 Alan Mackenzie * cc-mode.texi: Add a "Mode Initialization" section (as yet, content free) to "Configuration Strategies". Move "Minor Modes" into the "Commands" chapter. Remove the configuration instructions from its submode "Auto-newlines". Outline the default configuration for auto-newlines here. Rename the old "Auto-newline insertion" to "Customizing Auto-newline Mode" and make it a @chapter in its own right, containing four sections. The content of this @chapter is yet to be adapted. Amend the descriptions in "Minor Modes" of the key sequences, using @table rather than an unbroken textual paragraph. Amend "Electric Keys", so that there is explicit reference to "Clean-ups" in the right places. All electric actions are now collected together in this section. Condense the description of '*' and '/' in Electric keys. In "Clean-ups" insert "@tie{}" where a critical space was getting lost in line wrap. Tidy up a lot of wording. Introduce an experimental facility which will build either a GNU Emacs or an XEmacs specific info file. 2004-09-26 Martin Stjernholm * cc-engine.el (c-at-expression-start-p): New function like `c-at-statement-start-p' that additionally recognizes commas and expression parentheses as delimiters. 2004-09-24 Alan Mackenzie * cc-awk.el: Add character classes (e.g. "[:alpha:]") into AWK Mode's regexps. 2004-09-19 Alan Mackenzie * cc-mode.texi: Move the page "Hungry WS Deletion" into the "Commands" chapter, and revise this node for (hopefull) increased clarity. 2004-09-18 Alan Mackenzie * cc-mode.texi: Reduce the length of many node names, (following suggestion on emacs-devel). Tidy up some of the wording. 2004-09-17 Alan Mackenzie * cc-mode.texi: Added ACM to the list of authors. Renamed "Other Electric Commands" to "Electric Keys and Keywords" In "Electric Keys and Keywords", added descriptions of {, }, :, ;, ,,, and tidied up the wording a bit. Tidied up the wording and presentation of "Configuration Strategies". In "Customizing Filling and Line Breaking", expanded the description of c-comment-prefix-regexp. 2004-08-20 Alan Mackenzie * cc-mode.texi: Moved the "Commands" chapter to near the start of the file. Moved "Other Electric Commands" into the "Commands" chapter. Split "Text Filling and Line Breaking" into the "Filling and Line Breaking Commands" (a section under "Commands"), and "Customizing Filling and Line Breaking". 2004-08-18 Alan Mackenzie * cc-mode.texi: Update the master menu for the file. * cc-mode.texi: This change is the first stage in the restructuring of cc-mode.texi. Added new chapter, "Configuration Strategies", and converted "Hooks" and "Styles" (together with the latter's sub-nodes) into sections of this new chapter. Converted "Syntactic Symbols" and "Customizing Indentation" (together with the latter's sub-nodes "Interactive C.." and "Permanent C..") into sections of "Indentation Engine". "Customizing Indentation" has acquired "Line-Up Functions", "Custom Line-up Functions" and "Other Special Indentations" as sub-nodes, but has lost "Hooks" and "Styles"). "Advanced Customization", formerly a sub-node of "Customizing Indentation" is now a chapter in its own right. It has lost "Custom Line-Up Functions" and "Other Indentations". 2004-06-29 Martin Stjernholm * cc-engine.el (c-looking-at-inexpr-block): Added flag to avoid heuristics that doesn't work for unclosed blocks. (c-at-statement-start-p): New function. 2004-06-19 Martin Stjernholm * cc-mode.texi: Added an FAQ item about the open-paren-in-column-zero issue. 2004-05-25 Martin Stjernholm * cc-defs.el, cc-vars.el (c-emacs-features): Moved from cc-vars to cc-defs for dependency reasons. Fixed the POSIX char class test to check that it works in `skip-chars-(forward|backward)' too. * cc-align.el (c-lineup-arglist): Fixed bug when the first argument starts with a special brace list. 2004-05-23 Martin Stjernholm * cc-engine.el (c-forward-type): Fixed promotion bug when `c-opt-type-concat-key' is used (i.e. in Pike). * cc-engine.el (c-looking-at-special-brace-list): Fixed bug when the inner char pair doesn't have paren syntax, i.e. "(< >)". 2004-04-28 Alan Mackenzie Amend doc(-strings) to say that doesn't insert WS into a CPP line. * cc-cmds.el, cc-vars.el (c-indent-command, c-tab-always-indent): Amend doc strings. * cc-mode.texi (@node Indentation Commands): Amend documentation of c-tab-always-indent. 2004-04-20 Martin Stjernholm * cc-align.el (c-lineup-multi-inher): Made it syntactic whitespace safe. 2004-04-19 Martin Stjernholm * cc-engine.el, cc-fonts.el: Fixes in handling of Objective-C directives, e.g. directives spanning lines should work reasonably well now. (c-put-c-type-property, c-clear-c-type-property): New helpers. (c-forward-objc-directive): New function to move over any ObjC directive. (c-just-after-func-arglist-p, c-guess-basic-syntax, c-basic-matchers-before): Use it. (c-font-lock-objc-iip-decl): Removed. * cc-engine.el (c-guess-basic-syntax): Some improvement in the template arglist recognition. 2004-04-17 Martin Stjernholm * cc-styles.el (c-style-alist): Fixed several inconsistencies in the Whitesmith style. * cc-mode.texi: Documented c-lineup-after-whitesmith-blocks. Some other fixes. * cc-align.el (c-lineup-after-whitesmith-blocks): New lineup function to get lines after Whitesmith style blocks correctly indented. (c-lineup-whitesmith-in-block): Backed out the compensation for opening parens since it's done using `add' lists in the style definition instead. Don't use the anchor position since it varies too much between the syntactic symbols. :P * cc-vars.el (c-valid-offset): Updated. * cc-mode.texi: Updated the doc for offset specifications on `c-offsets-alist'. * cc-engine.el (c-evaluate-offset): Extended to handle lists where the offsets are combined according to several different methods: `first', `min', `max', and `add'. Report offset evaluation errors with `c-benign-error' so that some kind of reindentation still is done. * cc-engine.el (c-guess-basic-syntax): Anchor `arglist-intro' the same way as `arglist-cont-nonempty' and `arglist-close'. * cc-engine.el (c-guess-basic-syntax): Fixed similar situations for `arglist-cont-nonempty' and `arglist-close'. 2004-04-16 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed anchor position for `arglist-intro' when there are two arglist open parens on the same line and there's nothing in front of the first. * cc-mode.texi: Updated the parts dealing with line-up functions. Fixed some terminology to use the same words everywhere. * cc-langs.el (c-opt-identifier-concat-key-depth): New constant. * cc-fonts.el (c-basic-matchers-before): Fixed font locking of qualified names in Java, which previously could fontify common indexing expressions in many cases. The standard Java naming conventions are used to tell them apart. 2004-04-12 Martin Stjernholm * cc-defs.el: Use `cc-bytecomp-fboundp' and cc-bytecomp-boundp' in a number of places. 2004-04-09 Martin Stjernholm * cc-align.el (c-lineup-whitesmith-in-block): Fixed inconsistency wrt opening parens on the first line inside a paren block. * cc-defs.el (c-langs-are-parametric): Made it known at compile time to avoid warnings. * cc-defs.el (c-langs-are-parametric): Must be known at compile time for the sake of `c-major-mode-is'. (c-mode-is-new-awk-p): Made it a macro to delay expansion of `c-major-mode-is' in the event that this is used inside a `c-lang-defconst'. 2004-04-04 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Fixed a macro related issue. 2004-04-03 Alan Mackenzie * cc-engine.el, cc-cmds.el, cc-awk.el: Remove (nearly all of) the cruft associated with AWK Mode's former concept of "virtual semicolons". * cc-styles.el, cc-vars.el, cc-engine.el, cc-cmds.el, cc-awk.el: 1. Add character classes (e.g. "[:alpha:]") into AWK Mode's regexps. 2. Adapt c-beginning-of-statement, c-end-of-statement (together with subfunctions) to use the new notion of "virtual semicolon" in place of the old awkward special handling for AWK. There remains much cruft in cc-awk.el, cc-cmds.el and cc-engine.el to clear out. * cc-awk.el: Change the terminology of regexps: A char list is now [asdf], a char class [:alpha:]. Include code for char classes. Set c-awk-NL-prop on lines ending in open strings. (Bug fix.) * cc-cmds.el: (c-ascertain-adjacent-literal): In the backwards direction, now recognises AWK regexp delimiters as string delimiters. (c-after-statement-terminator-p): Adapt for virtual semicolons; check more rigorously for "end of macro". (c-back-over-illiterals, c-forward-over-illiterals): Adapt for virtual semicolons; (c-beginning-of-statement): Adapt for virtual semicolons; Separate out the code for forward movement into ... (c-end-of-statement): Now contains the code for forward movement, adapted for virtual semicolons. * cc-engine.el: (c-ws*-string-limit-regexp): new regexp. (c-forward-single-comment, c-backward-single-comment): Comment out the (now redundant) "special" AWK stuff. * cc-styles.el, cc-vars.el: Change the settings of c-string-par-start, c-string-par-separate to be more like Text Mode than Fundamental Mode. 2004-03-27 Alan Mackenzie * cc-engine.el, cc-styles.el: Add in two checks for user errors, thus eliminating cryptic and unhelpful Emacs error messages. (1) Check the arg to `c-set-style' is a string. (2) Check that settings to `c-offsets-alist' are not spuriously quoted. 2004-03-26 Alan Mackenzie * cc-mode.texi: Synchronise with the 5.31 latest version, 5.197, in particular enhancing the documentation of `c-add-style'. 2004-03-26 Martin Stjernholm * cc-mode.texi: Enhanced the style doc somewhat more. 2004-03-25 Martin Stjernholm * cc-defs.el (c-major-mode-is): Fixed expansion inside `c-lang-defconst' so that it works better with fallback languages. * cc-defs.el (c-add-language): Fixed a typo that caused it to fail to record the base mode. 2004-03-23 Martin Stjernholm * cc-fonts.el (c-font-lock-declarations): Always narrow to the fontified region so that fontification doesn't occur outside it (could happen e.g. when fontifying a line with an unfinished declaration). 2004-03-18 Martin Stjernholm * cc-engine.el (c-syntactic-re-search-forward): Fixed bug so that it doesn't go past the closing paren when PAREN-LEVEL is used. Reordered the syntax checks to get more efficient skipping in some situations. 2004-03-18 Alan Mackenzie * cc-awk.el, cc-defs.el, cc-engine.el, cc-langs.el, cc-mode.el: Amend the concept of "virtual semicolons" (in the indentation engine) for languages like AWK, such that they are now conceptually attached to end of the last token of a statement, not the end of the line. (In AWK Mode, however, the pertinent text property is still physically set on the EOL.) Remove the specific tests for awk-mode, thus facilitating the introduction of other language modes where EOLs can end statements. (Note: The funtionality in cc-cmds.el, specifically c-beginning/end-of-statement has yet to be amended.) * cc-awk.el: Regexps for analysing AWK code have been moved to near the start of the file. ^L now separate sections of the file. New defconsts: c-awk-non-eol-esc-pair-re, c-awk-blank-or-comment-line-re, c-awk-one-line-possibly-open-string-re, c-awk-regexp-one-line-possibly-open-char-class-re, c-awk-one-line-possibly-open-regexp-re, c-awk-one-line-non-syn-ws*-re. New functions: c-awk-at-vsemi-p, c-awk-vsemi-status-unknown-p. * cc-defs.el: New macros c-at-vsemi-p, c-vsemi-status-unknown-p. * cc-langs.el: Added `#' into AWK Mode's value of c-stmt-delim-chars. New c-lang-defvars: c-at-vsemi-p-fn, c-vsemi-status-unknown-p-fn (in a new page). * cc-engine.el: In c-beginning-of-statement-1, c-crosses-statement-barrier-p, c-guess-basic-syntax, replace numerous awkward forms like (if (c-major-mode-is 'awk-mode) (c-awk-prev-line-incomplete-p)) with (c-at-vsemi-p). Fix a few typos. In c-guess-basic-syntax, new variable before-ws-ip, the place just after char-before-ip appears. * cc-mode.el: Fix what's almost a semantic ambiguity in a comment. 2004-03-02 Martin Stjernholm * cc-cmds.el (c-electric-brace): Cleaned up using `c-tentative-buffer-changes'. * cc-defs.el (c-region-is-active-p): Simplified and converted to macro to choose between Emacs and XEmacs at compile time. (c-set-region-active): New set counterpart to `c-region-is-active-p'. (c-tentative-buffer-changes): New macro to handle temporary buffer changes in a convenient way. (c-tnt-chng-record-state, c-tnt-chng-cleanup): Internal helpers for `c-tentative-buffer-changes'. * cc-cmds.el (c-electric-brace): Don't trip up on a line continuation which might precede the newly inserted '{'. 2004-03-01 Martin Stjernholm * cc-engine.el (c-syntactic-re-search-forward): Fixed cases where it could loop indefinitely. 2004-02-22 Martin Stjernholm * cc-engine.el (c-looking-at-inexpr-block): Tightened up the checks for paren sexps between the point and the keyword, to avoid some false alarms. * cc-engine.el, cc-langs.el (c-looking-at-inexpr-block): Fixed a situation where an error could be thrown for unbalanced parens. Changed to make use of c-keyword-member' to avoid some repeated regexp matches. (c-opt-lambda-key, c-opt-inexpr-block-key, c-opt-inexpr-class-key): These language variable are no longer necessary. (c-block-stmt-kwds): New language constant used by c-looking-at-inexpr-block'. (c-guess-basic-syntax): Removed an optional check that looked at the existence of the now removed language variables. * cc-engine.el (c-fdoc-shift-type-backward, c-forward-decl-or-cast-1): Fixed invalid recognition of C++ style object instantiation expressions as declarations in some contexts. This bug only affected languages where the declarator can't be enclosed in parentheses. 2004-02-21 Alan Mackenzie * cc-mode.texi (c-block-comment-prefix): State that it's default setting, "* " gets overridden by the default style, gnu. 2004-02-19 Martin Stjernholm * cc-styles.el (c-style-alist): Fixed the GNU style to insert newlines before and after substatement braces. 2004-02-16 Martin Stjernholm * cc-engine.el: Improved the heuristics for recognizing function declaration headers and the handling of C++ style member init lists. (c-just-after-func-arglist-p): Rewritten to use `c-forward-decl-or-cast-1'. Now behaves a bit differently too. (c-beginning-of-member-init-list): Removed since it isn't used anymore. (c-guess-basic-syntax): Case 5B adapted for the new `c-just-after-func-arglist-p'. Cases 5B.1 and 5B.3 merged. Cases 5D.1 and 5D.2 removed since they aren't trigged anymore (case 5B.1 covers all cases now). * cc-defs.el (c-point): Added 'bosws and 'eosws. 2004-02-15 Alan Mackenzie * cc-styles.el, cc-vars.el: Correct silly bug in previous commit. * cc-cmds.el, cc-styles.el, cc-vars.el: New variables c-string-par-start/separate c-sentence-end-with-esc-eol, initialised in c-setup-paragraph-variables, used in string scanning subroutines of c-beginning-of-statement. 2004-02-06 Alan Mackenzie * cc-cmds.el (c-electric-brace): don't delete a comment which precedes the newly inserted `{'. 2003-12-08 Martin Stjernholm * cc-fonts.el (c-font-lock-declarators): Handle array size specs correctly. Only fontify identifiers in front of '(' with as functions - don't accept any paren char. Tightened up initializer skipping to stop before function and class blocks. 2003-12-07 Martin Stjernholm * cc-engine.el, cc-langs.el: Rewrote the recognition function for declaration level blocks. It should now cope with templates better and also be a lot more comprehensible. (c-looking-at-decl-block): The new function. (c-search-uplist-for-classkey): The old one. It's now a wrapper for compatibility. (c-add-class-syntax, c-guess-continued-construct, c-guess-basic-syntax): Adapted for `c-looking-at-decl-block'. (c-decl-block-key): Changed to tell apart ambiguous and unambiguous keywords. Pike specials are now handled directly in the code instead. (c-block-prefix-disallowed-chars, c-block-prefix-charset): New language constants and variables to make the backward skip in `c-looking-at-decl-block' as tight as possible. (c-nonsymbol-token-char-list): New language constant. * cc-engine.el (c-backward-<>-arglist): New function to find balanced template arglists backwards. * cc-defs.el (c-make-bare-char-alt): New helper for making char classes for `c-syntactic-skip-backward'. * cc-engine.el (c-guess-basic-syntax): Simplified case 16D - can't be a class-close at that point. * cc-engine.el (c-guess-basic-syntax, c-add-class-syntax): Don't narrow out the enclosing declaration level. This makes everything a lot easier, and it was actually only four small places that needed it to work. Some places that previously did `widen' are removed now, which has the effect that `c-guess-basic-syntax' never will look at things outside the current narrowment now. The anchor position for `topmost-intro' is affected by this, but it was so bogus it was basically useless before, and now it's equally bogus but in a slightly different way. (c-narrow-out-enclosing-class): Gone. (c-most-enclosing-brace, c-least-enclosing-brace): Don't filter to the narrowed region. (c-least-enclosing-brace): Removed silly optional argument. * cc-engine.el (c-beginning-of-decl-1): Fixed bug where the point could be left directly after an open paren when finding the beginning of the first decl in the block. * cc-engine.el (c-parse-state): Don't use the syntax table when filtering out legitimate open parens to be recorded. This could cause cache inconsistencies when e.g. `c++-template-syntax-table' was temporarily in use. * cc-engine.el (c-beginning-of-decl-1): Fixed bug where the point could be left directly after an open paren when finding the beginning of the first decl in the block. 2003-12-06 Martin Stjernholm * cc-engine.el, cc-fonts.el (c-forward-keyword-clause): Specify which submatch to use. * cc-langs.el (c-symbol-start): Include '@' in ObjC. (c-decl-start-re): No no longer any need for special treatment of ObjC due to the above. (c-other-block-decl-kwds): Handle "extern" in ObjC too since it presumably follows C in that regard. * cc-langs.el (c-identifier-ops, c-after-id-concat-ops): New language constants to specify operator tokens inside identifiers in a more high level way. (c-opt-identifier-prefix-key): New internal language constant. (c-opt-identifier-concat-key, c-opt-after-id-concat-key, c-identifier-start, c-identifier-key): Now completely calculated from other constants. (c-identifier-last-sym-match): Decommissioned since it's no longer used. (c-operators): Use `c-identifier-ops'. Documented `postfix-if-paren'. * cc-engine.el (c-forward-name): Removed the optimization when c-identifier-key is equal to c-symbol-key since it doesn't work in byte compiled files. Don't record empty regions as identifiers. * cc-langs.el (c-filter-ops): New helper function to simplify access to `c-operators' and its likes. (c-operator-list, c-all-op-syntax-tokens, c-nonsymbol-token-regexp, c-<>-multichar-token-regexp, c-<-op-cont-regexp, c->-op-cont-regexp, c-expr-kwds, c-primary-expr-regexp, c-cast-parens): Use it. * cc-defs.el (c-lang-const): Fixes to allow use without an explicit language in functions. * cc-defs.el (c-make-keywords-re): Added an appendable variant of adornment. 2003-12-05 Martin Stjernholm * cc-langs.el (c-any-class-key): Removed unused language variable. (c-type-decl-prefix-key): Removed some now unnecessary cruft from the Pike value. * cc-engine.el (c-on-identifier, c-simple-skip-symbol-backward): Small fix for handling "-" correctly in `skip-chars-backward'. Affected the operator lfun syntax in Pike. (c-forward-label): Small fix for handling "-" correctly in `c-syntactic-skip-backward'. * cc-engine.el (c-on-identifier, c-simple-skip-symbol-backward): Small fix for handling "-" correctly in `skip-chars-backward'. Affected the operator lfun syntax in Pike. 2003-12-04 Martin Stjernholm * cc-langs.el (c-make-init-lang-vars-fun): Disabled the diagnostic message about precompiled language vars not being used. * cc-langs.el (c-paren-nontype-kwds): The GCC keyword "__attribute__" is followed by a parenthesis. (c-type-start-kwds, c-prefix-spec-kwds, c-prefix-spec-kwds-re, c-specifier-key, c-not-decl-init-keywords): Some cleanup using new language constants `c-type-start-kwds' and `c-prefix-spec-kwds'. 2003-11-30 Martin Stjernholm * cc-engine.el (c-invalidate-sws-region-after): Fixed bug that could cause an error from `after-change-functions' when the changed region is at bob. * cc-fonts.el, cc-langs.el, cc-engine.el: Internal cleanups to properly detect the declared identifiers in various declarations. (c-decl-start-kwds): New language constant to recognize declarations that can start anywhere. Used for class declarations in Pike. (c-specifier-key, c-not-decl-init-keywords, c-decl-prefix-or-start-re, c-find-decl-prefix-search, c-find-decl-spots): Implement `c-decl-start-kwds'. (c-other-decl-kwds, c-postfix-decl-spec-kwds, c-decl-hangon-kwds, c-decl-hangon-key, c-forward-decl-or-cast-1): Separated the handling of the compiler specific extension keywords into a new language constant `c-decl-hangon-kwds' that defines keyword clauses to be ignored in declarations. (c-forward-id-comma-list, c-forward-keyword-clause): Don't skip past unrecognized tokens when handling `c-colon-type-list-kwds'. Necessary to stop at the declared identifier in e.g. IDL valuetype declarations. (c-typedef-decl-kwds, c-typeless-decl-kwds, c-type-list-kwds, c-prefix-spec-kwds-re, c-postfix-spec-kwds, c-after-suffixed-type-decl-key, c-opt-postfix-decl-spec-key, c-forward-decl-or-cast-1): Recognize the declared identifier in class and enum declarations as such and not as part of the type. (c-forward-decl-or-cast-1, c-forward-label): Relaxed the interpretation of PRECEDING-TOKEN-END when there's no preceding token. (c-forward-decl-or-cast-1): Don't disregard sure signs of declarations when there's some syntax error later on. (c-complex-decl-matchers): Did away with a reference to `c-specifier-key'. 2003-11-23 Martin Stjernholm * cc-engine.el (c-maybe-labelp): Provide no default value - this variable is always dynamically bound. 2003-11-22 Martin Stjernholm * cc-engine.el, cc-fonts.el, cc-langs.el, cc-menus.el, cc-mode.el, cc-styles.el, cc-vars.el, cc-align.el, cc-awk.el, cc-cmds.el, cc-defs.el: Changed the policy for marking up functions that might do hidden buffer changes: All such internal functions are now marked instead of those that don't. (c-beginning-of-macro, c-end-of-macro, c-(forward|backward)-comments, c-(forward|backward)-single-comment, c-parse-state, c-on-identifier, c-(fast-|slow-|)in-literal, c-literal-limits, c-collect-line-comments, c-literal-type): Allow these functions to make hidden buffer changes, so that they are free to use text property caching later on. (c-electric-backspace, c-electric-delete-forward, c-electric-pound, c-electric-brace, c-electric-slash, c-electric-star, c-electric-semi&comma, c-electric-colon, c-electric-lt-gt, c-electric-paren, c-electric-continued-statement, c-indent-command, c-indent-region, c-mask-paragraph, c-indent-new-comment-line, c-context-line-break): Added `c-save-buffer-state' calls to comply with the changed semantics of the functions above. * cc-engine.el (c-beginning-of-statement-1): Fixed a bug when macros occur in obscure places. Optimized the sexp movement a bit. 2003-11-21 Alan Mackenzie * cc-awk.el, cc-cmds.el, cc-engine.el, cc-mode.el, cc-mode.texi: Enhancements for c-beginning-of-statement to work in AWK Mode: cc-awk.el: Supersede c-awk-NL-prop value `;' (completed statement) with `}' (statement completed by closing brace or semicolon) and `$' (statement completed by EOL). New functions: c-awk-virtual-semicolon-ends-prev-line-p, c-awk-virtual-semicolon-ends-line-p, c-awk-skip-semantic-ws-forward, c-awk-skip-semantic-ws-backward, c-awk-at-statement-end-p. cc-cmds.el: Simplify the structure of functions c-forward-over-illiterals, c-back-over-illiterals. Enhance these two functions and c-beginning-of-statement to handle AWK Mode. cc-engine.el: Enhance c-forward-single-comment, c-backward-single-comment for AWK mode. Attempt to clarify their doc-strings. cc-mode.el: Put M-a and M-e into awk-mode-map. cc-mode.texi: Document that M-a and M-e now work in AWK mode. Fix minor typos. 2003-11-21 Martin Stjernholm * cc-engine.el, cc-fonts.el, cc-langs.el: Cleaned up the label handling. Labels are now recognized in a uniform and more robust way, regardless of context. Text properties are put on all labels to recognize the following declarations better. Multiword labels are handled both in indentation and fontification for the benefit of language extensions like Qt. For consistency, keywords in labels are now fontified with the label face instead. That also applies to "case" and "default". (c-beginning-of-statement-1): Fixed some bugs in the label handling. Disregard `c-nonlabel-token-key' in labels that begin with `c-label-kwds'. (c-find-decl-spots): Support that the callback adds more `c-decl-end' spots to find. (c-forward-decl-or-cast-1): Don't treat a list of plain identifiers followed by a colon as a declaration. (c-forward-label): New function to recognize labels. (c-guess-basic-syntax): Replaced uses of `c-label-key' with `c-forward-label'. Moved the label recognition cases (14 and 15) earlier since they aren't so context sensitive now. Handle labels on the top level gracefully. Moved access label recognition to the generic label case (CASE 15) - removed CASE 5E. (c-font-lock-declarations): Added recognition of labels in the same round since we need to handle labels in parallell with other declarations to recognize both accurately. It should also improve speed. (c-simple-decl-matchers, c-basic-matchers-after): Moved `c-font-lock-labels' so that it only is used on decoration level 2 since `c-font-lock-declarations' handles it otherwise. (c-complex-decl-matchers): Removed the simplistic recognition of access labels. (c-decl-prefix-re): Removed the kludges that was necessary to cope with labels earlier. (c-decl-start-re): New language variable to make `c-font-lock-declarations' stop for the special protection labels in Objective-C that start with '@'. (c-label-key): Removed since it's no longer used. (c-recognize-colon-labels, c-label-prefix-re): New language constants to support recognition of generic colon-terminated labels. (c-type-decl-end-used): `c-decl-end' is now used whenever there are colon terminated labels. * cc-align.el (c-lineup-arglist): Fixed bug when the first argument starts with a special brace list. 2003-11-19 Martin Stjernholm * cc-engine.el, cc-fonts.el (c-forward-decl-or-cast-1, c-font-lock-declarations): Broke out the declaration and cast recognition from `c-font-lock-declarations' to a new function, so that it can be used in the indentation engine. 2003-11-16 Martin Stjernholm * cc-engine.el (c-guess-continued-construct, c-guess-basic-syntax): Check a little more carefully if it's an function declaration when an unknown construct followed by a block is found inside a statement context. This avoids macros followed by blocks to be taken as function declarations. (c-guess-continued-construct): Changed the analysis of a statement continuation with a brace open to `substatement-block', for consistency with recognized statements. (c-add-stmt-syntax): Don't continue to the surrounding sexp if the start is in a position so that `c-beginning-of-statement-1' jumped to the beginning of the same statement. * cc-engine.el (c-guess-continued-construct, c-guess-basic-syntax): Check a little more carefully if it's an function declaration when an unknown construct followed by a block is found inside a statement context. This avoids macros followed by blocks to be taken as function declarations. (c-guess-continued-construct): Changed the analysis of a statement continuation with a brace open to `substatement-block', for consistency with recognized statements. 2003-11-15 Martin Stjernholm * cc-fonts.el, cc-cmds.el, cc-engine.el (c-forward-<>-arglist-recur): Don't accept binary operators in the arglist if we're in a function call context, i.e. if `c-restricted-<>-arglists' is set. That avoids template recognition in cases like "if (a < b || c > d)". (c-restricted-<>-arglists): New more appropriate name for `c-disallow-comma-in-<>-arglists'. Accessing functions updated for the variable name change. 2003-11-07 Martin Stjernholm * cc-engine.el (c-find-decl-spots): Fixed bug in backing up to the start of the literal. Fixed bug with the point on the wrong side of the search limit that could happen when the start position is inside a literal. * cc-engine.el (c-parse-state, c-invalidate-state-cache): Modified the use of `c-state-cache-end' so that it's kept a little bit back to increase the hit rate. (c-parse-state): Changed the macro handling and fixed some glitches. Macro context is checked more often than necessary now, but otoh less garbage conses are generated. * cc-engine.el (c-parse-state, c-invalidate-state-cache): Cache the last position where `c-state-cache' applies. This can speed up refontification quite a bit in blocks where there are many non-brace parens before the point. (c-state-cache-end): New variable for this. (c-guess-basic-syntax, c-debug-parse-state): Adapted for the new cache variable. 2003-11-06 Martin Stjernholm * cc-engine.el (c-find-decl-spots): Take more care to get close initial continue positions when the start position is inside a literal or macro. Do not call the callback for spots before the start position (which can happen e.g. for `c-decl-end' spots inside comments). Optimize better in special cases when the region is a single line inside a literal or macro (typically when the current line is refontified). 2003-11-04 Martin Stjernholm * cc-engine.el (c-syntactic-re-search-forward): Fix bug where the match data could get clobbered if NOT-INSIDE-TOKEN is used. 2003-11-02 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Simplified calls to `c-add-stmt-syntax' - there's no need to explicitly whack off entries from the paren state. * cc-engine.el (c-add-stmt-syntax): Narrowed down the special case for "else if" clauses. 2003-11-01 Martin Stjernholm * cc-engine.el (c-looking-at-inexpr-block, c-add-stmt-syntax): Use `c-recognize-paren-inexpr-blocks'. * cc-langs.el (c-recognize-paren-inexpr-blocks): New language variable to recognize the gcc extension with statement blocks inside expressions. * cc-engine.el (c-add-stmt-syntax): Restructured to make it somewhat more comprehensible. The argument AT-BLOCK-START is no longer used and hence removed. (c-guess-continued-construct, c-guess-basic-syntax): Updated calls to `c-add-stmt-syntax'. * cc-engine.el (c-beginning-of-statement-1): Don't allow parens in labels. (c-backward-to-decl-anchor): Use `c-beginning-of-statement-1' instead of duplicating parts of it. This fixes bogus label recognition. * cc-engine.el (c-backward-to-decl-anchor): Use `c-beginning-of-statement-1' instead of duplicating parts of it. This fixes bogus label recognition. * cc-mode.texi: Extended the doc on c-label-minimum-indentation a little. * cc-align.el (c-gnu-impose-minimum): Reverted to the old method of checking the context in which to apply the minimum indentation, so that it isn't enforced in e.g. namespace blocks. * cc-vars.el (c-inside-block-syms): New constant used by `c-gnu-impose-minimum'. It's defined close to `c-offsets-alist' to somewhat reduce the risk of becoming stale. * cc-cmds.el, cc-engine.el (c-shift-line-indentation): Moved from cc-cmds to cc-engine to allow use from cc-align. 2003-10-29 Martin Stjernholm * cc-engine.el (c-beginning-of-inheritance-list): Cope with fully qualified identifiers containing "::". q 2003-10-26 Martin Stjernholm * cc-engine.el (c-add-type, c-check-type, c-forward-name, c-forward-type): Improved storage of template types in `c-found-types' so that they can be recognized better. (c-syntactic-content): Added option to skip past nested parens. * cc-engine.el (c-forward-name): Set `c-last-identifier-range' all the time. It's less work that way. Handle that there might not be an identifier to store in `c-last-identifier-range'. (c-forward-type): Handle that `c-last-identifier-range' might be nil from `c-forward-name'. * cc-defs.el: (c-safe-scan-lists, c-(go-)?(up|down)-list-(forward|backward)): Added limit arguments. * cc-defs.el (c-save-buffer-state): Use `unwind-protect' to work even if the form fails. * cc-defs.el (c-make-keywords-re): Added kludge for bug in `regexp-opt' in Emacs 20 and XEmacs when strings contain newlines. * cc-engine.el (c-parse-state): Speedup when moving far down in a large file in one go. (c-get-fallback-start-pos): New helper function for `c-parse-state'. 2003-10-25 Martin Stjernholm * cc-vars.el (c-emacs-features): Use a space in front of the name of the temporary buffer. That also avoids dumping problems in XEmacs due to undo info being left around after the buffer is killed. * cc-mode.texi: Document c-lineup-assignments and c-lineup-math. * cc-align.el (c-lineup-assignments): New lineup function which is like `c-lineup-math' but returns nil instead of `c-basic-offset' when it doesn't match. (c-lineup-math): Changed to use `c-lineup-assignments'. 2003-10-20 Alan Mackenzie * cc-cmds.el: Fix some bugs in subfunctions of c-beginning-of-statement. New subfunctions c-in-comment-line-prefix-p, c-narrow-to-comment-innards. 2003-10-14 Martin Stjernholm * cc-fonts.el, cc-langs.el: Use `c-simple-ws' instead of hardcoded char classes whereever possible. Changed a couple of places to use skip by syntax instead of skip by char class. * cc-langs.el (c-unterminated-block-comment-regexp): Fixed a bug in the regexp that caused extreme backtracking. 2003-10-13 Martin Stjernholm * cc-engine.el (c-in-knr-argdecl): Look closer at the function arglist to see if it's a K&R style declaration.

(c-block-comment-regexp, c-unterminated-block-comment-regexp): New language constants to break up things a bit. (c-simple-ws): New language constant for simple whitespace. * cc-defs.el (c-concat-separated): New convenience function. * cc-defs.el (c-make-keywords-re): Added kludge for bug in `regexp-opt' in Emacs 20 and XEmacs when strings contain newlines. Allow and ignore nil elements in the list. 2003-10-06 Alan Mackenzie * cc-cmds.el: Comment out a (n almost certainly superfluous) check, (eq here (point-max)) in c-beginning-of-statement. 2003-10-02 Alan Mackenzie * cc-cmds.el: Tidy up the comments in c-beginning-of-statement and subfunctions. 2003-10-01 Alan Mackenzie * cc-awk.el: Replace calls to put-text-property to the more flexible c-put-char-property and c-clear-char-properties. Add the author's email address. 2003-09-30 Alan Mackenzie * cc-langs.el: New variable, c-block-comment-start-regexp. 2003-09-29 Alan Mackenzie * cc-cmds.el: 1. Fix stupid error in previous commit. 2. Fix bug with M-e, when point is inside the closing "*/" of a block comment. * cc-cmds.el: Tidy c-beginning-of-sentence (and subfunctions) so that it works at BOB and EOB. * cc-cmds.el: Correct small inaccuracy in previous check-in. * cc-cmds.el, cc-vars.el: More updating of c-beginning-of-statement, including new variable c-block-comment-start-regexp. 2003-09-24 Martin Stjernholm * cc-engine.el (c-parse-state): Fixed bug that could cause errors when the state cache contains info on parts that have been narrowed out. 2003-09-22 Martin Stjernholm * cc-mode.texi, cc-vars.el (c-comment-prefix-regexp): Document that `c-setup-paragraph-variables' has to be used when this variable is changed; it doesn't work to reinitialize the mode since that typically clobbers the variable. * cc-styles.el (c-setup-paragraph-variables): Made it interactive. 2003-09-21 Martin Stjernholm * cc-langs.el (c-known-type-key): Optimize simple symbols from `*-font-lock-extra-types' so that there's no need to use `regexp-opt' on those lists. * cc-fonts.el (c-font-lock-declarations): Fixed recognition of constructors and destructors for classes whose names are matched by `*-font-lock-extra-types'. * cc-langs.el (c-type-list-kwds): If "operator" is followed by an identifier in C++ then it's a type. * cc-langs.el (c-type-decl-suffix-key): Fix when `c-type-modifier-kwds' is empty. 2003-09-19 Martin Stjernholm * cc-fonts.el (c-font-lock-invalid-string): Fix when there are several strings on the same line. * cc-engine.el (c-literal-limits): Removed the compatibility function for older emacsen. `c-literal-limits-fast' has now taken the place of this function. * cc-vars.el (c-emacs-features): Removed compatibility with older emacsen: We now require 'pps-extended-state. 2003-09-17 Martin Stjernholm * cc-fonts.el (c-font-lock-invalid-string): Fixed eob problem that primarily affected XEmacs. Don't use faces to find unterminated strings since Emacs and XEmacs fontify strings differently - this function should now work better in XEmacs. 2003-09-15 Alan Mackenzie * cc-cmds.el: New function c-beginning-of-sentence, which obviates the need to hack sentence-end. This now handles escaped newlines in strings correctly. Correct minor bugs in c-move-over-sentence and in c-beginning-of-statement. 2003-09-13 Alan Mackenzie * cc-cmds.el (c-beginning-of-statement (and subfunctions)): Adapt c-\(back\|forward\)-over-illiterals such that movement over macros and code are rigorously separated from eachother. Correct a few incidental bugs. 2003-09-08 Martin Stjernholm * cc-cmds.el (c-electric-brace): Fixed a bug in the `expand-abbrev' workaround which caused braces to disbehave inside macros. * cc-engine.el (c-forward-keyword-clause): Fixed error handling. This bug could cause interactive font locking to bail out. 2003-08-31 Martin Stjernholm * cc-engine.el (c-just-after-func-arglist-p): Handle paren-style types in Pike. Also fixed some cases of insufficient handling of unbalanced parens. 2003-08-29 Alan Mackenzie * cc-cmds.el: Restructure c-beginning-of-statement: Improve its doc-string. Improve the handling of certain specific cases. 2003-08-26 Martin Stjernholm * cc-cmds.el (c-electric-brace): Work around for a misfeature in `expand-abbrev' which caused electric keywords like "else" to disappear if an open brace was typed directly afterwards. 2003-08-24 Martin Stjernholm * cc-engine.el, cc-fonts.el, cc-langs.el (c-guess-basic-syntax): Changed the way class-level labels are recognized; they can now contain essentially any symbols. (c-opt-extra-label-key): New language variable to cope with the special protection label syntax in Objective-C. (c-opt-access-key): Removed; this is now handled better by `c-nonlabel-token-key' and `c-opt-extra-label-key'. (c-complex-decl-matchers): Update to handle that `c-opt-access-key' no longer exists. * cc-engine.el (c-guess-basic-syntax): Make use of the improved label recognition in `c-beginning-of-statement-1'. * cc-engine.el (c-beginning-of-member-init-list): Recognize bitfields better. * cc-engine.el (c-beginning-of-inheritance-list): Removed some cruft and fixed a bug that could cause it to go to a position further down. * cc-langs.el, cc-engine.el (c-beginning-of-statement-1): Improved detection of labels in declaration contexts. (c-beginning-of-decl-1): Use it. (c-nonlabel-token-key): New language constant and variable needed by `c-beginning-of-statement-1'. * cc-engine.el (c-guess-basic-syntax): Fixed bug that manifested itself due to the correction in `c-forward-sexp'. * cc-defs.el (c-forward-sexp, c-backward-sexp): Made these behave as documented when used at the buffer limits. * cc-mode.el, cc-engine.el, cc-langs.el (c-type-decl-end-used): Made this a language variable. * cc-mode.el (c-after-change): Widen the buffer to work correctly when `combine-after-change-calls' is used together with temporary narrowings. 2003-08-23 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Report labels correctly when the start point is immediately after the colon. 2003-08-22 Martin Stjernholm * cc-vars.el (c-extra-types-widget): The doc string is mandatory in `define-widget'. * cc-align.el, cc-langs.el (c-lineup-math): Don't align the operators "!=", "<=" and ">=" as assignment operators. (c-assignment-operators): New language constant that only contains the assignment operators. (c-assignment-op-regexp): New language variable used by `c-lineup-math'. 2003-08-21 Martin Stjernholm * cc-defs.el (c-parse-sexp-lookup-properties): Removed since it isn't used anymore. * cc-cmds.el (c-electric-lt-gt): Detect and mark angle bracket arglists such as template parens in C++. * cc-engine.el (c-syntactic-skip-backward): Fixed a bug in the last check-in. Some optimization. * cc-engine.el (c-syntactic-skip-backward): Fixed bug where it could stop at the same level in a preceding sexp when PAREN-LEVEL is set. * cc-mode.el (c-basic-common-init): Turn on syntax-table text property lookup only when it's needed. * cc-langs.el, cc-engine.el, cc-fonts.el, cc-mode.el: Changed the policy for paren marked angle brackets to be more persistent; once marked they remain marked even when they're found to be unbalanced in the searched region. This should keep the paren syntax around even when individual lines are refontified in multiline template arglists. (c-parse-and-markup-<>-arglists): New dynamically bound variable to control markup so that incorrect angle bracket arglists aren't marked in contexts where the correct value for `c-disallow-comma-in-<>-arglists' isn't known. (c-forward-<>-arglist, c-forward-<>-arglist-recur): The reparse argument has become `c-parse-and-markup-<>-arglists'. (c-remove-<>-arglist-properties): Removed - no longer used. (c-after-change-check-<>-operators): New function used on `after-change-functions' to avoid that "<" and ">" characters that are part of longer operators have paren syntax. (c-<>-multichar-token-regexp): New language variable used by `c-after-change-check-<>-operators'. (c-after-change): Call `c-after-change-check-<>-operators'. (c-font-lock-<>-arglists): Use the context properties set by `c-font-lock-declarations' to set `c-disallow-comma-in-<>-arglists' correctly to avoid doing invalid markup. (c-font-lock-declarations): Removed code that undoes the invalid markup done by `c-font-lock-<>-arglists'. (c-complex-decl-matchers): `c-font-lock-<>-arglists' now runs after `c-font-lock-declarations'. 2003-08-08 Martin Stjernholm * cc-engine.el (c-syntactic-skip-backward): Added paren-level feature. (c-guess-basic-syntax): Improved the anchor position for `template-args-cont' in nested template arglists. There's still much to be desired in this area, though. 2003-08-07 Martin Stjernholm * cc-engine.el (c-just-after-func-arglist-p): Safeguard against unbalanced sexps. 2003-08-03 Martin Stjernholm * cc-mode.el (c-init-language-vars-for): Add argument MODE. Renamed from c-init-c-language-vars'. (c-initialize-cc-mode): Change accordingly. (c-common-init): Ditto. (c-mode): Ditto. (c++-mode): Use function. (objc-mode): Ditto. (java-mode): Ditto. (idl-mode): Ditto. (pike-mode): Ditto. (awk-mode): Ditto. 2003-08-01 Martin Stjernholm * cc-engine.el (c-end-of-current-token): Return whether or not the point moved. (c-search-decl-header-end): Don't trip up on operator identifiers in C++ and operators like == in all languages. * cc-engine.el (c-backward-to-decl-anchor): Detect leading labels correctly. 2003-07-21 Alan Mackenzie * cc-cmds.el, cc-engine.el, cc-langs.el, cc-mode.texi, cc-vars.el: Make the "Text Filling and Line Breaking" commands work for AWK buffers. 2003-07-20 Martin Stjernholm * cc-mode.texi: Some updates due to the dropping of the support for older emacsen. * cc-defs.el, cc-engine.el (c-mode-is-new-awk-p): Removed; (c-major-mode-is 'awk-mode) can be used instead now. * cc-mode.el: Always set up AWK mode since emacsen where it doesn't work no longer are supported. * cc-mode.el, cc-styles.el, cc-vars.el, cc-defs.el, cc-engine.el, cc-fonts.el, cc-langs.el, cc-cmds.el: CC Mode now requires support for the syntax-table' text property, which rules out Emacs 19 and XEmacs < 21.4. Removed various compatibility cruft associated with those versions. * cc-defs.el, cc-fix.el: CC Mode now requires support for the `syntax-table' text property, which rules out Emacs 19 and XEmacs < 21.4. Removed various compatibility cruft associated with those versions. * cc-vars.el (c-emacs-features): CC Mode now requires support for the `syntax-table' text property. 2003-07-16 Martin Stjernholm * cc-fonts.el (c-nonbreakable-space-face): Remove the variable and use an extra quoted face name instead. All the emacsen flavors handle that correctly. * cc-defs.el (c-langelem-sym, c-langelem-pos, c-langelem-2nd-pos): Added accessor functions for syntactic elements. 2003-07-09 Martin Stjernholm * cc-engine.el (c-literal-faces): Declare as a variable since it might be modified. * cc-langs.el: (c++-make-template-syntax-table, c-syntactic-ws-start, c-syntactic-ws-end): Gave more consistent names to these language constants. 2003-07-08 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Do not do hidden buffer changes; there's third party code that calls this function directly. 2003-07-07 Martin Stjernholm * cc-fonts.el (javadoc-font-lock-keywords, autodoc-font-lock-keywords): Don't byte compile on font lock initialization when running from byte compiled files. 2003-07-06 Alan Mackenzie * cc-engine.el: Fix AWK mode indentation when previous statement ends with auto-increment "++". 2003-07-05 Martin Stjernholm * cc-langs.el, cc-styles.el (c-style-alist, c-lang-variable-inits, c-lang-variable-inits-tail): The values of these are changed, so declare them as variables and not constants. 2003-07-05 Martin Stjernholm * cc-langs.el, cc-styles.el (c-style-alist, c-lang-variable-inits, c-lang-variable-inits-tail): The values of these are changed, so declare them as variables and not constants. * cc-mode.el: Fixed some autoload problems: Try to ensure that the entry for ".c" extension comes before the one for ".C" on `auto-mode-alist', to behave better on case insensitive OS:es. Fixed incorrect entries that were added to `interpreter-mode-alist'. Moved the autoload directives for AWK to the top level since they aren't recognized anywhere else. Do not use the new AWK mode doc in the autoload form for the old AWK mode. 2003-07-03 Martin Stjernholm * cc-fonts.el (c-font-lock-complex-decl-prepare, c-font-lock-declarators, c-font-lock-declarations, c-complex-decl-matchers, c-basic-matchers-after): Use a text property to mark the items in in declarator lists to handle refontification inside multiline declarations better. 2003-07-02 Martin Stjernholm * cc-fonts.el (c-font-lock-declarations): Recognize a construct like "a * b = c;" as a declaration. * cc-menus.el (cc-imenu-init): Do not set `imenu-create-index-function' if the second argument is left out. This bug broke the imenu support in C, C++ and Java modes. 2003-06-19 Martin Stjernholm * Release 5.30. * cc-engine.el, cc-align.el (c-add-stmt-syntax, c-lineup-arglist, c-lineup-arglist-close-under-paren): Fixes to cope with special brace lists in Pike. 2003-06-19 Alan Mackenzie * cc-mode.el: awk-mode: Call c-awk-after-change to ensure syntax-table props at loading. * cc-fonts.el: Put (cc-require-when-compile 'cc-awk) to eliminate compile-time errors. 2003-06-18 Alan Mackenzie * cc-awk.el, cc-engine.el: Added code to analyze AWK top-level forms properly (c-guess-basic-syntax CASE 5P), c-awk-backward-syntactic-ws. 2003-06-17 Martin Stjernholm * cc-fix.el: cc-mode-19.el has been renamed to cc-fix.el since it now contains compatibility stuff for later versions than (X)Emacs 19. 2003-06-17 Martin Stjernholm * cc-langs.el (c-paren-nontype-kwds): New language constant. (c-other-decl-kwds, c-postfix-decl-spec-kwds): Added compiler specific declspec keywords: __attribute__ for gcc and __declspec for msvc. * cc-fonts.el (c-font-lock-declarations, c-complex-decl-matchers): Support specifiers in a couple more contexts to cope with msvc '__declspec'. * cc-engine.el (c-forward-keyword-clause): Support `c-paren-nontype-kwds'. 2003-06-16 Martin Stjernholm * cc-langs.el (c-primary-expr-regexp): Don't match a bare period as a float. 2003-06-16 Martin Stjernholm * cc-bytecomp.el (cc-bytecomp-setup-environment): Do not cover functions that have been bound. (cc-external-require): New macro to use for requiring external packages, to handle the environment correctly. * cc-defs.el, cc-fix.el, cc-fonts.el, cc-mode.el: Replaced external require's with `cc-external-require'. 2003-06-15 Martin Stjernholm * cc-engine.el (c-beginning-of-member-init-list, c-guess-basic-syntax): Fixes in handling of bitfields. 2003-06-13 Martin Stjernholm * cc-langs.el (comment-end): Put a space in front of the comment ender in C, as it was before the move from cc-mode.el. 2003-06-11 Alan Mackenzie * cc-fonts.el: Do not load cc-awk.elc or awk-font-lock-keywords unless there is an AWK Mode buffer. 2003-06-10 Alan Mackenzie * cc-awk.el: New file that implements AWK support, superseding the old separate derived mode in awk-mode.el. * cc-vars.el, cc-mode-19.el, cc-langs.el, cc-mode.el, cc-defs.el, cc-engine.el, cc-fonts.el: Changes for the new AWK support. 2003-06-05 Martin Stjernholm * cc-engine.el, cc-langs.el (c-decl-block-key, c-search-uplist-for-classkey): Check that the modifier is followed by "{" in Pike before considering it to start a class-like block. 2003-05-30 Martin Stjernholm * cc-mode.el (c-initialize-cc-mode): Added some compatibility to make this function behave somewhat more as documented for derived modes. It's still not enough to make the old AWK mode behave reasonably, but it's been like this a long time now so fixing it more might cause trouble elsewhere. :P 2003-05-29 Martin Stjernholm * cc-fonts.el (c-remove-font-lock-face): New macro to remove a font lock face properly (especially in XEmacs). * cc-bytecomp.el (cc-bytecomp-obsolete-fun): Added the same kludge as in `cc-bytecomp-obsolete-var' to avoid a confused compiler warning. * cc-engine.el (c-forward-type): Fixed a bug in the handling of concatenated types when the component types are known. * cc-fonts.el (c-constant-face-name): Added face name variable to avoid the use of `font-lock-constant-face' for constants in emacsen that doesn't have it. 2003-05-25 Martin Stjernholm * cc-styles.el, cc-vars.el, cc-cmds.el: Fixes for the syntactic symbols for module and composition blocks. 2003-05-17 Martin Stjernholm * cc-mode.el (c-basic-common-init): Use `open-paren-in-column-0-is-defun-start' if it exists and works. * cc-vars.el (c-emacs-features): Added `col-0-paren' to detect when `open-paren-in-column-0-is-defun-start' exists and actually works. 2003-05-07 Martin Stjernholm * cc-align.el (c-lineup-argcont, c-lineup-gcc-asm-reg): Don't quote nil in docstrings. 2003-04-14 Martin Stjernholm * cc-vars.el, cc-langs.el (c-primitive-type-kwds, c-font-lock-extra-types): "complex" and "imaginary" aren't keywords in C99, only macros that expand to the keywords "_Complex" and "_Imaginary", so make the former a bit less hardcoded by putting it on `c-font-lock-extra-types' instead. There are also "bool" and "_Bool" that work the same way. (c-constant-kwds): "false" and "true" are standard constant macros in C99. 2003-04-09 Martin Stjernholm * cc-menus.el, cc-langs.el, cc-engine.el, cc-fonts.el, cc-cmds.el: Fixed various regexps to use POSIX char classes when that is supported. * cc-defs.el (c-alpha, c-alnum, c-digit, c-upper, c-lower): New constants to make it easier to create regexps that use POSIX char classes in emacsen that support them. 2003-04-07 Martin Stjernholm * cc-vars.el (c-emacs-features): Detect in the regexp engine understands POSIX char classes. 2003-04-05 Martin Stjernholm * cc-mode.el (c-after-change): Added kludge for bug where this function sometimes gets positions outside the buffer range. 2003-03-30 Martin Stjernholm * cc-engine.el (c-beginning-of-member-init-list): Better handling of paretheses in unexpected places. * cc-engine.el (c-forward-<>-arglist-recur): Fixed a regexp match order problem that could cause empty template args on the form "<>" to be missed. 2003-03-23 Martin Stjernholm * cc-engine.el (c-parse-state): Added kludge to avoid an infinite loop when Emacs' open-paren-in-column-zero rule kicks in and causes the sexp functions to misbehave. 2003-03-06 Martin Stjernholm * cc-engine.el (c-beginning-of-member-init-list): Fixed bug when C++-like code is encountered in non-C++ mode. 2003-03-02 Martin Stjernholm * cc-defs.el (c-make-keywords-re): Added option to specify the language to look up `c-nonsymbol-key' in. 2003-02-24 Martin Stjernholm * cc-cmds.el, cc-engine.el (c-auto-newline-analysis): New dynamically bound variable to turn off the topmost-intro-cont/statement-cont kludge for brace lists during the analysis for the auto newline feature. This fixes some cases where the setting for `brace-list-open' on `c-hanging-braces-alist' didn't have any effect. 2003-02-23 Martin Stjernholm * cc-langs.el (c-literal-start-regexp): Yet another language variable. * cc-fonts.el (c-font-lock-doc-comments, c-find-invalid-doc-markup, javadoc-font-lock-keywords): Fixed fontification of the markup in Javadoc comments. * cc-engine.el: Fixes in face handling to cope with doc comments. (c-find-decl-spots): More failsafe skipping of comments and strings that only have been partially fontified. * cc-defs.el (c-got-face-at): New subst to test faces at positions easier. * cc-defs.el (c-safe-scan-lists): New wrapper macro to avoid the warnings with too many args to `scan-lists' in Emacs. 2003-02-22 Martin Stjernholm * cc-engine.el (c-syntactic-skip-backward): New function to make syntactic searches in the backward direction easier. (c-beginning-of-statement-1): Optimized skipping over large paren sexps somewhat. (c-safe-position): Removed the odd macro handling which was centered around the point instead of the passed position. 2003-02-16 Martin Stjernholm * cc-engine.el (c-in-knr-argdecl): Do not trip up on initialization expressions. * cc-align.el (c-lineup-arglist, c-lineup-close-paren, c-lineup-arglist-close-under-paren): Tuned the "macro block" heuristics to work better in nested arglist situations. 2003-02-10 Martin Stjernholm * cc-styles.el (c-set-offset): Don't find a default syntactic element through syntactic analysis if called outside a CC Mode buffer. 2003-02-09 Martin Stjernholm * cc-mode.el (c-basic-common-init): Install `c-fill-paragraph' on `fill-paragraph-function'. Although it's not the normal way to call it in a CC Mode buffer it makes a direct call to `fill-paragraph' work better. 2003-01-28 Martin Stjernholm * cc-vars.el, cc-mode.el (c-require-final-newline): Made this variable an alist to specify a value for each language. The default value causes `require-final-newline' to be set to t only in languages where the standard requires a final newline. 2003-01-25 Martin Stjernholm * cc-mode.el, cc-vars.el (c-require-final-newline): Added a variable to make the initialization of `require-final-newline' more configurable. * cc-vars.el (c-mode-common-hook): Do not change the format string to "CC Mode Common Hook" since that causes confusion (although it is a more accurate name). 2003-01-20 Martin Stjernholm * cc-fonts.el (javadoc-font-lock-keywords, autodoc-font-lock-keywords): Support for Javadoc and Pike Autodoc doc comments. * cc-vars.el (c-doc-comment-style): New variable to control the fontification of documentation comments on top of the normal mode font lock. 2003-01-14 Martin Stjernholm * cc-langs.el, cc-fonts.el (c-primary-expr-regexp, c-font-lock-declarations): Avoid false recognition of parens as casts when they are followed by an operator that is both prefix and infix. 2003-01-07 Martin Stjernholm * cc-cmds.el (c-guess-fill-prefix): Tuned the heuristics of when to use `c-block-comment-prefix' for an unclosed block comment. 2002-12-22 Martin Stjernholm * cc-engine.el, cc-langs.el (c-nonsymbol-sexp-kwds, c-forward-keyword-clause): Handle keywords like "extern" that can be followed by e.g. a string literal. * cc-defs.el (c-make-keywords-re): Make a regexp correctly with one submatch when adorn is set and the list is empty. 2002-12-14 Martin Stjernholm * cc-fonts.el (c-font-lock-declarations): Fixed a search that could go far past the relevant region and cause slowness. Do not limit the declaration detection to the fontified region since that can cause misfontification in multiline declarations. * cc-engine.el (c-find-decl-spots): Added limit argument to handle declarations spanning the fontification limit better. 2002-12-10 Martin Stjernholm * cc-engine.el (c-in-literal, c-literal-limits, c-literal-limits-fast, c-beginning-of-inheritance-list): Use the paren cache instead of the impaired ad hoc in `beginning-of-defun', so that these functions doesn't trip up on "{" in the first column inside strings or comments. 2002-12-06 Martin Stjernholm * cc-vars.el (c-hanging-braces-alist): Added `statement-cont' and made it auto newline free by default. * cc-cmds.el (c-electric-brace): Added `statement-cont' to the list of syntactic symbols to consider for auto newlines since it can be used for in-statement brace lists. * cc-vars.el (c-emacs-features): There's no need to have this constant autoloaded. 2002-12-04 Martin Stjernholm * cc-fonts.el (c-font-lock-declarations): Use `c-recognize-typeless-decls' to avoid fontifying some macro constructs as declarations in languages where a preceding type is mandatory. * cc-langs.el (c-recognize-typeless-decls): New language variable. 2002-11-30 Martin Stjernholm * cc-align.el (c-lineup-close-paren): Use `c-syntactic-eol' when checking if the open paren ends its line. * cc-langs.el (c-syntactic-eol): Handle a line continuation backslash. 2002-11-26 Martin Stjernholm * cc-align.el (c-snug-do-while): Compatibility fix for changed structure in `c-syntactic-context'. 2002-11-25 Martin Stjernholm * cc-engine.el (c-parse-state): Filter angle bracket arglist parens in a better way than disabling the syntax table properties completely. * cc-fonts.el (c-cpp-matchers): Handle line continuations in cpp expressions. Do not fontify symbols after #ifdef etc as variables since that isn't consistent with how the face is used elsewhere (i.e. only for the definition of the symbol). 2002-11-24 Martin Stjernholm * cc-mode.el: Added autoload directives for the interface functions in cc-langs. 2002-11-19 Martin Stjernholm * cc-fonts.el (c-font-lock-declarations): Added a property to handle refontication in multiline declaration arglists better. (c-font-lock-<>-arglists): Fix to handle recursive template arglists better. (As a side effect this will make fontification work better in older emacsen too.) * cc-engine.el (c-forward-<>-arglist, c-remove-<>-arglist-properties): Use a common text property `c-type' for all sorts of CC Mode char classification, to avoid cases when then same char is given conflicting types. (c-forward-<>-arglist): New reparse argument to control that aspect explicitly. (c-forward-name, c-forward-type): Changes in the handling of recursive template arglists. Fixes to cope with the new 'known type classification. 2002-11-16 Martin Stjernholm * cc-mode.el (c-basic-common-init): Added the new char property `c-type' to `text-property-default-nonsticky'. * cc-defs.el (c-put-char-property, c-get-char-property, c-clear-char-property, c-clear-char-properties): Generalized `c-put-char-syntax' and `c-get-char-syntax' to handle any property. * cc-bytecomp.el (cc-bytecomp-defun): Fixed bug that caused existing function definitions to be overridden by phonies when the bytecomp environment is restored. 2002-11-15 Martin Stjernholm * cc-cmds.el (c-mask-paragraph): Masking is necessary in normal code too to avoid getting a fill prefix from a nearby comment. Changed the name from `c-mask-comment' to a more accurate one. * cc-defs.el, cc-mode.el: Changed the auto-load-alist strategy to not add entries on package load, to be defensive in the case that autoloads are updated in older emacsen. The bug that would occur in that case would probably be rather nasty for the average user. 2002-11-14 Martin Stjernholm * cc-fonts.el (c-font-lock-declarations): Fine tuning of the decision tree that tells declarations from expressions to produce better results in some ambiguous cases. * cc-fonts.el (c-font-lock-syntactic-face-function): Removed since it doesn't give the control we want. (c-font-lock-invalid-string): Replacement for `c-font-lock-syntactic-face-function' that puts the error face on the string opener only, to avoid the annoying excessive use of the error face while a string literal is being written. (c-basic-matchers-before): Use `c-font-lock-invalid-string'. * cc-engine.el (c-string-syntax, c-string-limit-regexp): Added constants to use when handling string limits, since not all old emacsen react well to the "|" syntax class. (c-literal-limits, c-literal-limits-fast, c-literal-type): Use `c-string-syntax' and `c-string-limit-regexp'. Replaced some hardcoded comment start regexps with `c-comment-start-regexp'. 2002-11-08 Martin Stjernholm * cc-mode.el: Added an association for pike-mode on `intepreter-mode-alist'. 2002-11-04 Martin Stjernholm * cc-mode.el: Add the `auto-mode-alist' entries to the end instead of the start of the list, to avoid overriding user additions that are made before this file is loaded when the entries don't correspond to any already on `auto-mode-alist'. This is done through the third append argument to `auto-mode-alist'. That doesn't exist in older (X)Emacsen, so the function is adviced in cc-defs. However, that advice doesn't help if the autoloads are updated in an old (X)Emacs with this version of CC Mode, but I believe it's unlikely that anyone does that when CC Mode isn't distributed with with it. * cc-defs.el (add-to-list): Added advice to get the optional third append argument in older (X)Emacsen. * cc-langs.el (c-keywords-obarray): Kludge for strange bug in Emacs that gives so odd errors that I frankly don't even muster to begin trying to narrow it down. If someone is so inclined, restore the commented code, byte compile, and try to open a C++ file or something in font lock mode. 2002-11-03 Martin Stjernholm * cc-langs.el: Updated the IDL support from the specs. This also adds the keywords for the variants PSDL and CIDL. (This is mostly done from reading the grammars only; very lightly tested.) * cc-langs.el (c-type-list-kwds): Added "new" in Java. * cc-fonts.el: Made sure that `parse-sexp-lookup-properties' is properly insulated from clobbering by the font-lock package at all relevant entry points. 2002-11-01 Martin Stjernholm * cc-langs.el (c-opt-after-id-concat-key): New language constant to make the recognition of identifier qualifiers more flexible. Recognize the identifier before ".*" as a qualifier in Java. (c-identifier-key): Recognize "::*" inside identifiers in C++. Recognize identifiers ending with ".*" in Java for the sake of import directives. (c-type-list-kwds, c-ref-list-kwds): Recognize "import" and "package" declarations in Java. * cc-vars.el (c-doc-face, c-doc-marker-face, c-doc-markup-face): Removed since they aren't used (and probably won't be). * cc-langs.el (c-ref-list-kwds): New language constant to specify keywords followed by references. (c-last-identifier-range): New variable to avoid going back to search for the identifier to font lock after a call to `c-forward-name'. (c-type-prefix-kwds, c-type-list-kwds): Fixed classification of "@interface" etc in Objective-C. * cc-engine.el (c-forward-keyword-clause): Fixed handling of keyword prefixes in `c-type-list-kwds' and `c-colon-type-list-kwds' clauses. (c-keyword-sym, c-keyword-member): New functions to lookup and categorize keywords. (c-forward-keyword-clause): New function to move over a keyword and its associated clause according to `c-<>-arglist-kwds' etc. * cc-langs.el (c-typeless-decl-kwds, c-type-list-kwds, c-colon-type-list-kwds, c-colon-type-list-re, c-paren-type-kwds): New language constants and variables to generalize the recognition of various language constructs. (c-keywords): Did away with the list of `*-kwds' constants. It's now built through macro expansion. (c-keywords-obarray): New language variable which contains each keyword as a symbol, to make fast reverse lookup of keywords to the `*-kwds' lists they come from. 2002-10-31 Martin Stjernholm * cc-defs.el (c-lang-defconst-eval-immediately): Added macro to be able to do direct evaluation in `c-lang-defconst' forms. * cc-engine.el (c-syntactic-re-search-forward): Fixed a bug which could cause the point to end up outside the containing sexp if PAREN-LEVEL was used. * cc-engine.el, cc-fonts.el, cc-langs.el: Generalized the C++ template arglist support to handle angle bracket arglists in any language. (c-recognize-<>-arglists, c-<>-arglist-kwds, c-opt-<>-arglist-start): New language variables to control angle bracket arglists. (c-opt-type-suffix-key): Use `c-recognize-<>-arglists' in Objective-C instead of matching a protocol reference list as a type suffix. 2002-10-30 Martin Stjernholm * cc-align.el (c-gnu-impose-minimum): Fixed a missing `save-excursion' that caused the point to jump around. 2002-10-26 Martin Stjernholm * cc-mode.el, cc-menus.el (objc-mode, cc-imenu-init): Fixed initialization bug that has made the Objective-C support inoperational since 5.26. (cc-imenu-objc-generic-expression): Updated submatch indices due to changes in `cc-imenu-c++-generic-expression'. (cc-imenu-objc-function): Don't add an empty "C" menu since imenu doesn't like that. 2002-10-25 Martin Stjernholm * cc-align.el (c-lineup-arglist, c-lineup-arglist-close-under-paren, c-lineup-close-paren): Added DWIM to the functions that line up at or after the arglist open paren to avoid that if there are brace blocks inside, e.g. when a macro contains a code block. 2002-10-24 Martin Stjernholm * cc-vars.el (objc-font-lock-extra-types): Changed default to treat identifiers starting with capital letters as types, according to Objective-C naming conventions. The types previously on the list is part of the language and therefore on `c-primitive-type-kwds' instead. * cc-fonts.el: Fixed font locking in Objective-C. Be more careful about returning nil from functions used directly as font-lock matchers. * cc-mode.el (c-font-lock-init): Made the syntax table modification element of `font-lock-defaults' parameterized over the languages. * cc-langs.el: Updated the Objective-C constants according to the language spec. The "@" chars that start directives are now considered part of the keywords to make things easier. 2002-10-23 Martin Stjernholm * cc-defs.el: (c-(up|down)-list-(forward|backward)): Made the position optional and added docstrings. (c-go-(up|down)-list-(forward|backward)): Added variants of the above that move point and return successfulness instead. 2002-10-21 Martin Stjernholm * cc-fonts.el (c-font-lock-<>-arglists): New function to fontify all occurrences of template arglists in C++. * cc-engine.el (c-disallow-comma-in-<>-arglists): New variable to be able to avoid false recognition of template arglists in some cases. 2002-10-20 Martin Stjernholm * cc-fonts.el, cc-langs.el (c-decl-prefix-re, c-font-lock-declarations): Match template open brackets to get a declaration in the first template argument. (c-complex-decl-matchers): Fontify the second type in a "class X = Y" expression in C++. 2002-10-19 Martin Stjernholm * cc-engine.el (c-forward-<>-arglist): Broke out the recursive part to a new function to improve efficiency when a nested template arglist search turns out to be futile. 2002-10-13 Martin Stjernholm * cc-menus.el (cc-imenu-java-generic-expression): Improved to avoid false matches on e.g. "else if (foo)". 2002-10-11 Martin Stjernholm * cc-engine.el (c-forward-token-2, c-backward-token-2): New functions that work like the -1 variants but that handles multicharacter operator tokens. * cc-engine.el (c-inside-bracelist-p, c-guess-basic-syntax): Did away with the hardcoded regexps to recognize "typedef" declaration prefixes, "extern" and "namespace" blocks, "enum"-style brace list declarations and Java-style array initializers with "new". * cc-langs.el (c-brace-list-decl-kwds, c-brace-list-key, c-inexpr-brace-list-kwds, c-opt-inexpr-brace-list-key): New language constants and variables to parameterize some more of the hardcoded regexps in cc-engine. 2002-10-10 Martin Stjernholm * cc-align.el (c-lineup-cascaded-calls): Do not allow cascaded call lists containing both "->" and ".". 2002-10-09 Martin Stjernholm * cc-align.el, cc-cmds.el, cc-defs.el, cc-engine.el, cc-fonts.el, cc-langs.el, cc-mode.el, cc-styles.el: New language variable system to make it easier to set up optimized language variables and to extend them in third party derived modes. cc-langs is no longer required at runtime. * cc-mode.el (c-basic-common-init): No longer initializes the language variables. It's necessary that the caller does that directly since the evaluated values for them now get compiled in directly. (c-font-lock-init, c-common-init): Separated the font-lock initialization from `c-common-init'. * cc-mode.el (c-define-abbrev-table): Do not override an existing abbrev table. (c-Java-defun-prompt-regexp): Moved here from cc-langs since cc-langs isn't always loaded at runtime. * cc-langs.el (c-make-init-lang-vars-fun, c-init-language-vars): Changed to allow language variable initialization from derived modes. (c-mode-menu): New language variable for the mode menu. (c-make-mode-syntax-table, c-mode-syntax-table, make-c++-template-syntax-table): New language variables for syntax tables. The code that initializes them has been moved to cc-mode to make it possible to avoid loading cc-langs at runtime. * cc-engine.el, cc-langs.el (c-hungry-delete-key, c-auto-newline, c-auto-hungry-string): Moved these state variables from cc-langs to cc-engine to make it possible to avoid loading cc-langs at runtime. * cc-defs.el (c-lang-defconst, c-lang-const): Moved from cc-langs and rewritten to make the language constant system usable from derived modes. (c-add-language): New function intended for use from derived modes that add new C-like languages. * cc-defs.el, cc-vars.el (c-buffer-is-cc-mode): Moved from cc-vars to cc-defs to define it during compilation. * cc-bytecomp.el (cc-require-when-compile): New support macro for compile time `require's. 2002-10-08 Martin Stjernholm * cc-defs.el, cc-mode.el (c-version): Moved from cc-mode to cc-defs to make it accessible to the other components. * cc-engine.el (c-forward-token-1, c-backward-token-1): Compatibility fix for emacsen that doesn't understand generic string delimiters. * cc-vars.el (c-emacs-features): Added detection of generic string and comment delimiters. * cc-defs.el, cc-langs.el (c-make-keywords-re): Changed interface to make it more extensible. * cc-langs.el, cc-defs.el (c-regexp-opt, c-regexp-opt-depth, c-make-keywords-re): Moved from cc-langs to cc-defs since they are generally useful. * cc-bytecomp.el, cc-defs.el (cc-eval-when-compile): Moved from cc-bytecomp to cc-defs to allow use at runtime. 2002-10-04 Martin Stjernholm * cc-bytecomp.el (cc-eval-when-compile): Workaround for a bug with nested `eval-when-compile' in XEmacs 21. 2002-09-27 Martin Stjernholm * cc-mode.el: Added autoloaded forms to install the appropriate file suffixes on `auto-mode-alist'. Necessary in XEmacs 21.5, and it can be useful elsewhere too. 2002-09-23 Martin Stjernholm * cc-align.el (c-lineup-cascaded-calls): Handle "." too, for use in Java. * cc-engine.el (c-forward-sws, c-backward-sws): Do not handle cpp directives in languages that doesn't have any. 2002-09-22 Martin Stjernholm * cc-langs.el (c-operators): Added a high level description of all operators, along with their precedence and associativity. * cc-align.el (c-lineup-multi-inher): Fixed bug where the position of the point and not the beginning of the line was used to calculate the indentation. 2002-09-18 Martin Stjernholm * cc-defs.el, cc-engine.el (c-backward-single-comment, c-backward-comments): Added kludge for the bug in `forward-comment' in most (X)Emacs versions where it moves back over the "*/" of a block comment if there's no matching "/*". This has become more important now since it can cause incorrect caching by `c-backward-sws'. 2002-09-16 Martin Stjernholm * cc-cmds.el (c-hungry-backspace, c-hungry-delete-forward): New functions to do hungry deletion regardless of hungry-delete mode. Contributed by Kevin Ryde. * cc-engine.el (c-forward-sws, c-backward-sws, c-invalidate-sws-region): Use text properties to cache regions with complex syntactic whitespace. This helps a lot in improving responsiveness when there are lots of comments and cpp directives before point. 2002-09-14 Martin Stjernholm * cc-guess.el, cc-langs.el, cc-menus.el, cc-mode.el, cc-styles.el, cc-vars.el, cc-engine.el, cc-fonts.el, cc-cmds.el, cc-defs.el: Introduced a classification of functions into those that make "hidden buffer changes" and those who don't. This is prompted by the increasing use of text properties for various things, to correctly cover the silly buffer modifications that is caused by text property changes. (c-save-buffer-state): New macro that's put around any code that can manipulate text properties. 2002-09-13 Martin Stjernholm * cc-mode.el (c-basic-common-init): Setup `text-property-default-nonsticky' to avoid messing with the rear-nonsticky property on each character in Emacs 21. * cc-defs.el (c-clear-char-syntax, c-put-char-syntax): Macros that sets and removes the syntax-table property on a single character and makes the property nonsticky in both directions in a suitable way for each (X)Emacs flavor. * cc-vars.el, cc-defs.el, cc-engine.el, cc-mode.el: Use `lookup-syntax-properties' in XEmacs to control whether the syntax-table property has any effect or not. (c-parse-sexp-lookup-properties): New macro that expands to either `parse-sexp-lookup-properties' or `lookup-syntax-properties'. 2002-09-12 Martin Stjernholm * cc-defs.el, cc-engine.el, cc-fonts.el: Put the faces into the buffer in the same way as the font-lock package does. This fixes a compatibility problem with XEmacs which sets an extra font-lock property. * cc-fonts.el (c-put-font-lock-face): A macro that finds out the right way to put font lock faces at compile time. We're definitely not byte code portable between Emacs and XEmacs now. * cc-engine.el (c-forward-sws, c-backward-sws): Implemented a cache for the last large skipped over syntactic whitespace. This also has most effect after many macros. * cc-engine.el, cc-defs.el (c-forward-syntactic-ws, c-backward-syntactic-ws): Utilize the limit better when one is passed. These are now macros to avoid a little overhead when no limit is given. (c-forward-sws, c-backward-sws): New functions called by the macros above to do the unbounded search. * cc-fonts.el (c-font-lock-declarations): Implemented a cache for the first backward search for a preceding `c-decl-prefix-re' match. This typically speeds up interactive refontification a lot on the top level of macro heavy header files. 2002-09-10 Martin Stjernholm * cc-vars.el (c-emacs-features): Added check for syntax text properties. * cc-mode.el (c-basic-common-init): Turn on `parse-sexp-lookup-properties' if it's supported. Define the variable in any case since it's used at runtime to check on this. * cc-langs.el (c-identifier-key): Support C++ destructor names. (c-identifier-start, c-op-token-regexp, c-type-modifier-kwds, c-opt-type-modifier-key, c-opt-type-component-key, c-typedef-specifier-kwds, c-typedef-specifier-key, c-paren-stmt-kwds, c-paren-stmt-key, c-syntactic-ws-start): A bunch of new language constants and variables to support the improved handling of names and types. * cc-fonts.el (c-font-lock-declarators, c-font-lock-declarations): Handle C++ template declarations and template references. Fontify complex types and names more accurately by delegating it to `c-forward-type' and `c-forward-name'. Fontify the identifiers in typedef declarations as types. * cc-engine.el (c-forward-<>-arglist): New function to move forward over a C++ template arglist. It also marks the '<' and '>' chars with paren syntax using the syntax-table property, to speed up later calls in emacsen that support syntax text properties (Emacs >= 20 and (undocumented) XEmacs 21). This also has the very interesting effect that if font locking is used with decoration level 3 or higher in these emacsen then template arglists will behave just like paren sexps with the various sexp movement commands. (c-forward-name): New function to move over a name. Simple in most languages except C++ where a name can contain template arglists and therefore almost arbitrary expressions. (c-on-identifier): Fix for Pike operator identifiers. (c-simple-skip-symbol-backward, c-syntactic-content, c-remove-<>-paren-properties): New helper functions. * cc-defs.el: (c-clear-char-syntax, c-mark-paren-open, c-mark-paren-close): New support functions to handle syntactic properties on C++ template arglist brackets. (c-put-type-face, c-put-reference-face): Helpers to put faces on regions, since there are a bit of that inside `c-forward-name' etc in cc-engine.el. * cc-engine.el, cc-fonts.el, cc-langs.el: Fixed the names on a number of regexp language variables to conform to the nomenclature and shortened some names. * cc-align.el, cc-cmds.el, cc-fonts.el, cc-engine.el (c-syntactic-re-search-forward): Removed the COUNT argument since it's never used. Added an argument to tell which subexpression whose end should be tested for syntactic relevance. Using this also removes some optimizations, so that it's possible to use a look behind subexpression that matches the end of a literal or a close paren when PAREN-LEVEL is used. (c-guess-continued-construct): Don't match <<= or >>= for the stream-op syntactic element. * cc-defs.el (c-paren-re, c-identifier-re): Removed these helper macros since better and more correct tools are now available in cc-langs.el. 2002-09-07 Martin Stjernholm * cc-align.el (c-lineup-string-cont): New lineup function to line up string literals that will be concatenated. 2002-09-05 Martin Stjernholm * cc-langs.el (c-populate-syntax-table): XEmacs classifies the hard space character as a symbol character but it's better to let it be in the punctuation class so that it's always highlighted with the inverted invalid face. It can perhaps be argued that that character is allowed in identifiers in some languages (haven't checked), but using it would still be extremely confusing. 2002-09-04 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Fixed a case when a labeled substatement caused incorrect association of the following continuation clause. * cc-engine.el (c-syntactic-re-search-forward): Handle the case when the syntactic match position is in the middle of a comment starter. (c-guess-continued-construct): Analyze the "K&R region" of a function nested inside a function as func-decl-cont and not statement-cont. New case E. Also cleaned up case C (stream-op recognition) a bit. * cc-engine.el (c-parse-state, c-check-state-cache): Moved the check on `c-state-cache-start' from `c-check-state-cache' to `c-parse-state' so that the state cache isn't zapped if `c-check-state-cache' but not `c-parse-state' is called during a temporary narrowing. This fixes a performance problem that could occur when `fill-paragraph' is used in font lock mode on a comment at the end of a large class or function. (c-state-cache-start): Fixed buffer localness. 2002-09-03 Martin Stjernholm * cc-langs.el: Updates from the C99 standard (or actually from the latest web accessible draft of it). 2002-09-02 Martin Stjernholm * cc-langs.el: Updated the keywords and operator tokens from the latest C++ and Java standards. Some other multichar token corrections. 2002-09-01 Martin Stjernholm * cc-cmds.el, cc-engine.el, cc-vars.el (c-syntactic-context, c-syntactic-element): Do not bind any values to these variables globally since they should always be dynamically bound. This makes it much easier to debug cases when they've gotten global values somehow. 2002-08-31 Martin Stjernholm * cc-langs.el (c-regexp-opt): Fix to work around the non-greedy behavior that the regexp engine sometimes exposes. This bug only shows in (X)Emacs 19 where there's no regexp-opt package. * cc-engine.el (c-syntactic-re-search-forward): Added a feature to filter out matches in the middle of tokens. Changed the comment to a docstring since I consider this function generally useful. * cc-defs.el (c-mode-symbol): Broke out a part of `c-mode-var'. * cc-align.el (c-lineup-cascaded-calls, c-lineup-gcc-asm-reg): Cope with that `c-most-enclosing-brace' might return nil. 2002-08-30 Martin Stjernholm * cc-engine.el (c-found-types, c-clear-found-types, c-add-type, c-check-type, c-add-complex-type, c-list-found-types, c-forward-type): Added a sort of symbol table for types: If a name is recognized as a type in a declaration it's added in an obarray to be able to recognize it in other ambiguous declarations. (c-remove-ws): New helper function to canonicalize fully qualified identifiers for `c-found-types'. * cc-defs.el (c-mode-var): New defsubst to access mode prefixed variables uniformly. 2002-08-23 Martin Stjernholm * cc-align.el (c-lineup-arglist-close-under-paren): Work correctly with nested arglist-cont-nonempty symbols. (c-lineup-arglist-operators): New lineup function to line up infix operators under the open paren of the surrounding sexp. 2002-08-20 Martin Stjernholm * cc-engine.el (c-forward-syntactic-ws): Fixed a bug that could cause an infinite loop if something that looks like a macro begins in the middle of a line. (c-parse-state): Fixed a bug that could cause `c-state-cache' to contain two conses in sequence when there's an unbalanced open paren in a macro. 2002-08-16 Martin Stjernholm * cc-defs.el (c-face-name-p): A defsubst to recognize the name of a face in a way that works also in XEmacs. * cc-engine.el (c-forward-type): New function to move past a type spec. * cc-engine.el (c-syntactic-re-search-forward): Fixed behavior when the limit is reached inside a comment, string, or a macro. * cc-align.el, cc-cmds.el, cc-engine.el (c-forward-single-comment, c-forward-comments, c-backward-single-comment, c-backward-comments): New replacements for `c-forward-comment' that wraps `forward-comment' more efficiently in each of the four different cases it's actually used. These replacements also treats line continuations as whitespace. (c-forward-comment): Removed. The four different cases above are basically different, so it's better to make them into separate functions than choose between them at runtime using the argument. 2002-08-11 Martin Stjernholm * cc-align.el (c-gnu-impose-minimum): Fixed bug due to the new placement of cpp-macro and comment-intro in the syntactic context, as pointed out by Kevin Ryde. Changed the method that decides whether point is inside a top-level construct to one that doesn't depend on the set of syntactic elements so much. * cc-defs.el (c-point): Use the functions `line-beginning-position' and `line-end-position' in emacsen that have them (currently Emacs 20 and later). 2002-07-27 Martin Stjernholm * cc-cmds.el (c-mask-comment): Fixed a bug that sometimes caused code after a closed block comment to be taken into account when the fill prefix is calculated. 2002-07-25 Martin Stjernholm * cc-align.el (c-lineup-arglist, c-lineup-argcont, c-lineup-math, c-lineup-cascaded-calls, c-lineup-gcc-asm-reg): Fixes to cope correctly with nested arglists for the lineups that can be used with arglist-cont-nonempty. 2002-07-24 Martin Stjernholm * cc-engine.el (c-add-stmt-syntax, c-guess-basic-syntax): Changed the anchor position of arglist-cont-nonempty and arglist-close so that a relative indentation like + can be used with consistent results. Prior to this, the indentation engine more or less assumed that arglist-cont-nonempty always used `c-lineup-arglist'. Those two syntax symbols also get the opening paren as an extra position, to make it possible for `c-lineup-arglist' to continue to do a proper job. * cc-engine.el (c-get-syntactic-indentation): A vector with an absolute indentation column now only overrides the indentation for surrounding structures, i.e. those whose syntactic elements are earlier in the `c-syntactic-context' list, but not nested ones. This so that e.g. `c-lineup-arglist' can reliably line up with the first argument but still allow relative indentation changes for nested things, e.g. the arglist-close of a nested argument list. This change means that the order in `c-syntactic-context' has become more essential. (c-guess-basic-syntax): Changes to make the nesting order of the returned syntax list correct. Compatibility note: This change means that `c-lineup-dont-change' now (again) isn't absolutely sure to keep the current indentation. However, I believe that most people use it for comments, macros and string literals, and since those are nested innermost it won't matter. 2002-06-17 Martin Stjernholm * cc-align.el, cc-defs.el, cc-engine.el, cc-vars.el (c-guess-basic-syntax, c-calc-offset, c-get-syntactic-indentation, c-syntactic-context): Extended the representation of the syntactic context: Previously it was a list containing cons cells of the found syntactic symbols and their relpos values. Now each element is instead a list containing the syntactic symbol in the first element and the relpos (if any) in the second. After that there might be more elements, depending on the syntactic symbol. The line-up functions get these additional elements as extra arguments. This change is slightly incompatible. Although the calling convention for line-up functions is strictly extended, the format of the `c-syntactic-context' variable has changed slightly. It's believed that this incompatibility is minor, though; not a single line-up function distributed with CC Mode needed to be changed, for instance. 2002-06-08 Martin Stjernholm * cc-styles.el (c-set-style, c-set-style-1): Added another state for the `dont-override' flag where it only keeps globally set variables. 2002-06-07 Martin Stjernholm * cc-mode.el (c-postprocess-file-styles): Do nothing except in CC Mode modes. 2002-06-02 Martin Stjernholm * cc-vars.el, cc-fonts.el, cc-langs.el, cc-mode.el: Added font lock support. * cc-engine.el (c-beginning-of-syntax): New function to be used for font-lock-beginning-of-syntax-function. It uses the state cache to quickly find a good position. * cc-defs.el (c-major-mode-is): Allow a list of modes. Made it a macro ensure that it's optimized to either eq or memq for constant arguments. * cc-mode.el (c-common-init): Did away with the hardcoded setting of `comment-column'; it's a user variable that we have no business meddling with. Since the default value for it is 32 in all supported (X)Emacs versions, it's also safe from a compatibility perspective. * cc-mode.el (c-basic-common-init): New function that contains only the syntax and line breaking/filling initialization. It's intended for use by other modes that embed CC Mode. 2002-05-25 Martin Stjernholm * cc-engine.el (c-add-stmt-syntax): Fixed some cases of wrong anchoring, e.g. for else-if compounds. 2002-05-01 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed anchor position for defun-open in K&R style functions. * cc-engine.el (c-in-knr-argdecl): Don't trip up on macros. (c-search-decl-header-end): Handle C++ template arguments more correctly. (c-beginning-of-decl-1): Fix when the declaration is first in a macro. 2002-04-30 Martin Stjernholm * cc-engine.el (c-beginning-of-decl-1): Better way to handle protection labels, one which doesn't get confused by inherit colons. (c-end-of-decl-1): Don't treat functions that have "class" or "struct" in the return type as classes or structs. 2002-04-27 Martin Stjernholm * cc-langs.el (c-make-keywords-re): Fixed the keyword adornment so that it works when a keyword ends with "_". 2002-04-24 Martin Stjernholm * cc-cmds.el (c-mask-comment): More fixes when used from `c-do-auto-fill' and point is at or near the limit of the comment. Fixed bug when the prefix from `c-guess-fill-prefix' is longer than the text on the first line of the comment when it's masked. 2002-04-23 Martin Stjernholm * cc-cmds.el (c-mask-comment): Fixed bug where point was moved to the following line when it was at the first line of a block comment where comment-start-skip matched to eol. Mon Apr 22 2002 Martin Stjernholm * Release 5.29 (Test version; this is not a real release.) * cc-engine.el: Incorporated change made in Emacs: Don't assume point-min == 1 when counting lines. * cc-mode.el: Incorporated changes made in Emacs: (c-define-abbrev-table): New function to pass the SYSTEM-FLAG to `define-abbrev' in a way that works in emacsen that doesn't support it. (c-mode-abbrev-table, c++-mode-abbrev-table, objc-mode-abbrev-table, java-mode-abbrev-table, pike-mode-abbrev-table): Mark all the predefined abbrevs as "system" abbrevs. (c-submit-bug-report): Make sure that the arguments to `insert' are strings. Sun Apr 21 2002 Martin Stjernholm * cc-align.el, cc-engine.el, cc-styles.el, cc-vars.el (c-guess-basic-syntax, c-lineup-topmost-intro-cont): Find correct anchor for statement-cont in top level constructs. Analyze variable initializations in top level constructs as topmost-intro-cont instead of statement-cont. That is an incompatible change but it gives better consistency. The new lineup function c-lineup-topmost-intro-cont' compensates for it and is now put on topmost-intro-cont by default. * cc-align.el, cc-engine.el, cc-langs.el (c-lineup-argcont): Lineup function contributed by Kevin Ryde. (c-in-gcc-asm-p): Function to recognize asm statements. Contributed by Kevin Ryde. (c-opt-asm-stmt-key): New language variable to recognize the beginning of asm statements. Sat Apr 20 2002 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Detect variable declarations after class and struct declarations correctly. Fixed limit error when finding the anchor for template-args-cont and topmost-intro-cont. Fri Apr 05 2002 Martin Stjernholm * cc-cmds.el (c-beginning-of-defun, c-declaration-limits): Find the "line oriented" declaration start too, just like the "line oriented" end is found. Thu Apr 04 2002 Martin Stjernholm * cc-vars.el (c-offsets-alist): A more sane default for `inexpr-statement'. This is not compatible, though. I think the benefit of a good default style outweights that in this case. Besides, `inexpr-statement' is not very common. Mon Apr 01 2002 Martin Stjernholm * cc-cmds.el (c-electric-delete-forward): Fixed silly bug that caused it to delete backwards in hungry delete mode. (It's amazing that this bug hasn't been reported.) * cc-cmds.el (c-declaration-limits, c-mark-function): Extracted the code to get the declaration limits from `c-mark-function' to a new `c-declaration-limits'. (c-indent-defun): Use the same method to get the limits of the declaration or macro as `c-mark-function'. * cc-engine.el (c-beginning-of-decl-1): Handle brace list initializers correctly (but costly; it ought to be integrated into `c-beginning-of-statement-1'). Sun Mar 31 2002 Martin Stjernholm * cc-cmds.el, cc-engine.el (c-beginning-of-defun, c-end-of-defun, c-mark-function): Rewritten to detect the declaration limits better. Now handles K&R argdecls, class definitions followed by variables etc. (c-in-knr-argdecl): Broke out the K&R argdecl test in `c-beginning-of-decl-1' to this new function. (c-end-of-statement-1, c-end-of-decl-1): Replaced `c-end-of-statement-1' with `c-end-of-decl-1', which correctly handles declarations that continue after the block. * cc-engine.el (c-syntactic-re-search-forward): Added an option to restrict matching to the top level of the current paren sexp. * cc-langs.el (c-opt-block-decls-with-vars-key): New regexp to recognize declarations that continue after the block. (c-syntactic-eol): New regexp to match a "syntactic" eol. Sat Mar 30 2002 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed a bug that often caused the backward limit to be lost at the top level. This improves performance a bit. * cc-engine.el (c-syntactic-re-search-forward): New function that works like `re-search-forward' but only returns matches in syntactically significant text. * cc-engine.el: Fixed a faster and more accurate way to recognize K&R argdecls. (c-beginning-of-decl-1): New function that put point at the beginning of the declaration. It handles K&R argdecl blocks. (c-guess-basic-syntax): Replaced the `knr-argdecl' recognition code with one that doesn't depend on the current indentation. The anchor position for `knr-argdecl' has also changed, but in a way that is unlikely to cause compatibility problems. Mon Mar 25 2002 Martin Stjernholm * cc-defs.el, cc-engine.el (c-forward-comment): `forward-comment' in XEmacs skips over line continuations in the backward direction. Correct for that. Also made this a defun since it has grown too large now to be a defsubst. * cc-langs.el: More convenient and decentralized setup of the language specific variables. The regexp-opt mangling is also done at compile time now. Tue Mar 19 2002 Martin Stjernholm * cc-cmds.el (c-indent-line-or-region): Call `c-indent-line' directly instead of through `indent-according-to-mode' so that this function always indents syntactically. * cc-engine.el (c-guess-basic-syntax): Fixed a bug where a class beginning with a nested class could cause an infinite loop (the state outside the narrowed out class is never used now). Sun Mar 17 2002 Martin Stjernholm * cc-align.el, cc-cmds.el, cc-engine.el, cc-vars.el: Fixes so that the context sensitive analysis inside macros is restricted to the bodies of #define's; other things, like #if expressions, never have anything in common with their surroundings. The old `cpp-macro-cont' syntax is now used in situations where the syntactic analysis isn't applicable, and a new syntactic element `cpp-define-intro' is used to add indentation in #define bodies. (c-lineup-cpp-define): New name for `c-lineup-macro-cont' to better reflect its use. * cc-engine.el (c-guess-basic-syntax): Ignore line continuation backslashes in the detection of `arglist-cont-nonempty'. * cc-align.el: Use the vector form in the return value in all cases where lineup functions return absolute columns. Sat Mar 16 2002 Martin Stjernholm * cc-engine.el (c-add-stmt-syntax, c-guess-basic-syntax): Anchor `brace-list-intro' and `brace-list-close' better for brace lists nested inside expressions. * cc-engine.el, cc-langs.el, cc-mode.el, cc-styles.el: Cleaned up the various language specific variables and their initialization. The keyword regexps are now lists that are combined with regexp-opt. Some variables have changed names to fit better with the naming convention. * cc-defs.el, cc-vars.el (c-buffer-is-cc-mode): The value is the mode symbol of the original CC Mode mode. (c-major-mode-is): Compare against the buffer local variable `c-buffer-is-cc-mode', which is faster than using `derived-mode-class'. Sun Mar 10 2002 Martin Stjernholm * cc-engine.el (c-forward-syntactic-ws, c-backward-syntactic-ws, c-forward-token-1, c-backward-token-1, c-in-literal, c-literal-limits, c-collect-line-comments, c-literal-type, c-on-identifier, c-guess-basic-syntax): These functions are now considered part of the "CC Mode API" and may be used by other code. That's signified by making their documentation into docstrings. (c-whack-state, c-hack-state, c-skip-case-statement-forward): Removed these internal functions since they aren't used. (c-forward-to-cpp-expression): Classified this function as internal. Thu Mar 07 2002 Martin Stjernholm * cc-langs.el (c-ObjC-class-key, c-Java-class-key): Simplified these regexps; the class keywords they contain ought to be enough to avoid false matches, so checking for following identifiers etc is just unnecessary (and might also fail for oddly formatted code). Fri Feb 08 2002 Martin Stjernholm * cc-engine.el, cc-cmds.el (c-forward-comment-lc): New function that behaves like `c-forward-comment', with the exception that line continuations are treated as whitespace. (c-beginning-of-statement): Use `c-forward-comment-lc', to work correctly in macros and other places where line continuations should be treated as whitespace. * cc-engine.el (c-guess-basic-syntax): Analyze a normal label in a switch block as a case label, to get consistent lineup with the case labels. * cc-engine.el (c-backward-syntactic-ws): Fixed bug in skipping over a macro that ends with an empty line. * cc-styles.el: Require cc-align since styles added with `c-add-style' often contains references to functions defined there, and so the `c-valid-offset' check might otherwise complain on them. Sun Jan 20 2002 Martin Stjernholm * cc-align.el, cc-mode.texi, cc-vars.el: Added two new lineup functions: (c-lineup-knr-region-comment): A new lineup function to get (what most people think is) better indentation of comments in the "K&R region" between the function header and its body. (c-lineup-gcc-asm-reg): New lineup function for better indentation inside gcc asm blocks. Contributed by Kevin Ryde. (c-offsets-alist): Use `c-lineup-gcc-asm-reg' and `c-lineup-knr-region-comment' in the default offset configuration, since these two functions have little impact outside their intended use, and they generally do the right thing when they kick in. * cc-engine.el (c-guess-continued-construct, c-guess-basic-syntax): Handle nested functions in all languages, not just Pike. In C and C++ there's a gcc extension for this, and it also gives better treatment of macros that are followed by blocks. * cc-langs.el (c-symbol-key): Made this variable mode specific, to handle Pike special symbols like `== better. Sat Jan 19 2002 Martin Stjernholm * cc-cmds.el, cc-engine.el, cc-vars.el (c-report-syntactic-errors): A new variable to control the syntactic error messages. It defaults to off; since CC Mode ignores most syntactic errors it might as well ignore them all for the sake of consistency. Sat Jan 05 2002 Martin Stjernholm * cc-mode.texi: Updated the Limitations and Known Bugs section. Various small fixes. Thu Nov 29 2001 Martin Stjernholm * cc-engine.el (c-looking-at-inexpr-block): Optimization. Can give a noticeable speedup if there's a large preceding function or class body. Sun Nov 25 2001 Martin Stjernholm * cc-align.el, cc-cmds.el: Use more efficient and correct insertion functions in many places. Always inherit text properties correctly if the text is permanent. Also do it for speed in temporary insertions, since I figure it's less work to continue the surrounding text properties than to break them. * cc-styles.el (c-read-offset): Unbind SPC in the completion to make it easier to enter lists. Wed Nov 21 2001 Martin Stjernholm * cc-cmds.el (c-beginning-of-defun): Fixed bug where c-state-cache was clobbered. * cc-cmds.el, cc-engine.el (c-calculate-state): Moved from cc-cmds.el to cc-engine.el due to dependency. Mon Oct 22 2001 Martin Stjernholm * cc-engine.el (c-parse-state): Ignore unbalanced open parens in macros (if point isn't in the same one). Sat Oct 13 2001 Martin Stjernholm * cc-cmds.el (c-context-open-line): New function that is the `open-line' equivalent to `c-context-line-break'. * cc-mode.el (c-mode-base-map): Compatibility fix for Emacs 21 since `indent-new-comment-line' has been changed to `comment-indent-new-line' there. Sun Oct 07 2001 Martin Stjernholm * cc-engine.el, cc-langs.el (c-stmt-delim-chars, c-stmt-delim-chars-with-comma): New variables containing the character sets used to recognize statement/declaration boundaries. These variables might help to support languages like javascript and awk, where newlines sometimes delimits statements. (c-crosses-statement-barrier-p): Use `c-stmt-delim-chars' as the set of statement delimiting characters, to allow it to be changed dynamically and per-mode. Sat Oct 06 2001 Martin Stjernholm * cc-engine.el (c-looking-at-bos, c-looking-at-inexpr-block, c-add-stmt-syntax, c-guess-basic-syntax): Treat blocks directly inside function calls like "bare" statements inside function calls, and not like in-expression statements. This to make indentation of such blocks consistent with other statements inside macro calls. * cc-engine.el (c-guess-basic-syntax): Made arglist-cont anchor correctly in arglists that contain statements. * cc-engine.el (c-guess-basic-syntax): Fixed consistent anchoring of defun-block-intro in defuns in code blocks (can only occur in Pike). * cc-engine.el (c-looking-at-inexpr-block, c-looking-at-inexpr-block-backward): Changed the arguments to require containing sexps and paren state, for better efficiency. Fri Oct 05 2001 Martin Stjernholm * cc-cmds.el, cc-engine.el, cc-vars.el: Improved anchoring of statement and handling of labels in front of substatements. (c-guess-continued-construct, c-guess-basic-syntax): Improved and unified anchoring at statements. Statements beginning with comments or labels are now avoided, by going out of blocks and containing statements if necessary. This nesting handling also fixes the case when there's a statement after a block open brace. Added the syntactic symbol `substatement-label'. (c-electric-colon): Map the new `substatement-label' to `label' when consulting `c-hanging-colons-alist'. (c-offsets-alist): Added substatement-label. Updated the comments for the new anchoring positions at statements. * cc-engine.el (c-guess-basic-syntax): Use more sane anchor points for knr-argdecl-intro and access-label. They used to refer to some point on the same line, a bug which was neutralized by a kludge in `c-get-syntactic-indentation' which ignored such anchor points. (c-get-syntactic-indentation): Removed the kludge that was necessary due to buggy anchor points. * cc-engine.el (c-guess-basic-syntax): Do not check the absence of a comma before arglist-close (case 7A) in any language, since there's nothing better to do that case anyway. Added special case to make in-expression statements be recognized as normal arglist-cont if we're directly in a macro arglist, for consistency with other "bare" statements. * cc-engine.el (c-looking-at-bos): Added optional limit arg for backward searches. * cc-engine.el (c-looking-at-inexpr-block): Anchor gcc in-expression statements at the surrounding open parenthesis. Treat a class body as an in-expression class if it's used in an object clone expression in Pike. * cc-engine.el (c-get-offset, c-get-syntactic-indentation): Allow several anchor positions in the list of syntactic symbols. Only the first is used as the base for the offset calculation. Tue Oct 02 2001 Martin Stjernholm * cc-cmds.el (c-indent-defun): Indent the current macro if inside one at the top level. Do not throw an error if used at the top level outside a macro. * cc-cmds.el (c-backslash-region): Do tab width alignment only if the backslashes can't be aligned with surrounding backslashes. * cc-engine.el (c-end-of-macro): New function. * cc-engine.el (c-least-enclosing-brace): Rewritten to not be destructive. Sat Sep 29 2001 Martin Stjernholm * cc-cmds.el (c-context-line-break): Only do a macro line break when point is inside the content of it; if it's in the cpp keyword a normal line break is done. * cc-engine.el (c-guess-basic-syntax): Do not add cpp-macro-cont inside the argument list to a #define. Thu Sep 27 2001 Martin Stjernholm * cc-defs.el (c-forward-comment): Implemented a kludge to avoid the problem most forward-comment incarnations have with `\' together with comment parsing. Wed Sep 26 2001 Martin Stjernholm * cc-engine.el (c-check-state-cache): Fixed bug which could cause the state returned by `c-parse-state' to lack a closed paren element. That in turn could result in very long searches, since it's common that they start from the last preceding close brace. Tue Sep 25 2001 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Do not treat else-if as a single continuation, since that'd make it hard to get the right anchor point when there's a line break between the two keywords. This change causes else-clause to be anchored on the closest preceding else-if and not always on the starting if, but that doesn't affect the indentation for any reasonably sane style. Also introduced a noerror flag. (c-beginning-of-closest-statement): Removed; c-beginning-of-statement-1 now avoids the problem this one solved. * cc-engine.el (c-guess-continued-construct, c-guess-basic-syntax): Better and more uniform anchor points for 'statement-cont and 'substatement. The effect is noticeable mostly when there's a label on the same line as the beginning of the statement, or when there are more stuff before the start of the statement. * cc-engine.el (c-looking-at-inexpr-block): Added flag to disable looking at the type of the surrounding paren since that confuses c-beginning-of-statement-1 and a couple of other places. * cc-engine.el (c-guess-basic-syntax): Avoid stepping to the previous statement in case 18. Improvements in recognition of statement blocks on the top level. Sun Sep 23 2001 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1, c-crosses-statement-barrier-p): Rewritten to get a well defined and documented behavior. This fixes some tricky cases in recognition of do-while constructs. (c-backward-to-start-of-do, c-backward-to-start-of-if): Removed; use c-beginning-of-statement-1 instead. (c-guess-continued-construct, c-guess-basic-syntax): Various fixes to not depend on the bugs previously in c-beginning-of-statement-1. Cleanups in cases 18 and 17 to use the new behavior of c-beginning-of-statement-1 better. Fixed recognition of catch blocks inside macros. * cc-engine.el (c-backward-syntactic-ws): Fixed bug in skipping over a macro. * cc-langs.el (c-label-kwds): New variable to contain the appropriate c-*-label-kwds value. * cc-vars.el (defcustom-c-stylevar): Fixed value evaluation bug that caused the widget for c-block-comment-prefix to bug out. Fri Sep 21 2001 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Improved recognition of statements: They are now recognized in contexts where they normally can't occur, e.g. on the top level or in function call arguments. This is mainly useful to recognize statements in macros at the top level, and in arguments to macros. The cases has been moved around quite a bit, and case 10 has been copied to case 18. (The cases has not been renumbered because of this.) (c-guess-continued-construct): New function which has the rules which are common between cases 10 and 18. * cc-engine.el (c-beginning-of-statement-1, c-backward-to-start-of-do, c-backward-to-start-of-if): Fixes so that they really obey the passed limits. (c-safe-position): Return nil if the state doesn't contain a suitable position. (c-guess-basic-syntax): Fixes some too short limits in calls to c-beginning-of-statement-1. Some fixes for top level analysis in ObjC mode. * cc-engine.el (c-beginning-of-statement-1): Fixed bug in do-while statements where the body is not a block. * cc-styles.el (c-set-style): Reset c-special-indent-hook to its global value if in override mode. Fixes problem where functions on that hook remained after style switch. * cc-engine.el (c-evaluate-offset, c-get-offset): Use c-benign-error to report the c-strict-syntax-p error. Thu Sep 20 2001 Martin Stjernholm * cc-align.el, cc-defs.el, cc-cmds.el, cc-engine.el, cc-vars.el: Several fixes to treat macros as code and not literals and to handle line continuations transparently. (c-skip-ws-forward, c-skip-ws-backward): New macros to skip through whitespace and line continuations, but not comments and macros. (c-in-literal): No longer recognizes macros as literals by default. An extra flag argument is required to do that. (c-macro-start, c-query-macro-start, c-query-and-set-macro-start): Added a cache for the macro start position. (c-forward-syntactic-ws, c-backward-syntactic-ws): Fixes for more speed when limits are given. Workaround for bad behavior in forward-comment in some emacsen when it hits a buffer limit with a large repeat count. (c-lineup-macro-cont): Improved behavior when c-syntactic-indentation-in-macros is nil. (c-syntactic-indentation-in-macros, c-backslash-max-column, c-auto-align-backslashes): New customization variables to control macro handling. * cc-menus.el (cc-imenu-c++-generic-expression): Fixes to handle line continuations. * cc-defs.el, cc-styles.el (c-get-style-variables, c-set-offset): Report style errors with message and ding instead of error signal. This to avoid interrupted mode init if there's some style problem. (c-benign-error): New macro to report errors that doesn't need to interrupt the operation. * cc-defs.el (c-point): Added eonl and eopl positions. Tue Sep 18 2001 Martin Stjernholm * cc-cmds.el (c-electric-brace, c-indent-region): Removed most of the c-state-cache fiddling, since the global state cache now handles this. * cc-engine.el (c-guess-basic-syntax): Fixed bug when there's an open paren at the very first char of the visible buffer region. * cc-engine.el (c-parse-state, c-check-state-cache): Cache the state globally and invalidate it below every buffer change with the new after change function `c-check-state-cache'. This gives a considerable performance boost when editing large functions or classes. * cc-engine.el (c-whack-state-after): Slight optimization. Sun Sep 16 2001 Martin Stjernholm * cc-engine.el, cc-langs.el, cc-align.el: Improvements to syntactic analysis inside macros: (c-block-stmt-1-kwds, c-block-stmt-2-kwds): New variables used by `c-guess-basic-syntax'. (c-parse-state): Fixed bug with braces inside macros when using cached state info. (c-forward-to-cpp-expression): New function to aid in syntactic analysis inside macros. (c-beginning-of-statement-1, c-backward-syntactic-ws): Fixes to work better inside macros. (c-forward-syntactic-ws): Whitespace between the # and the command should be allowed in preprocessor directives. (c-lineup-macro-cont): New lineup function to get context sensitive indentation inside macros. (c-offsets-alist): Made `c-lineup-macro-cont' the default for cpp-macro-cont. Sat Sep 15 2001 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1, c-forward-syntactic-ws): Fixes to handle continued lines. (c-backward-to-start-of-if, c-guess-basic-syntax): Do syntactic analysis inside macros. Sat Sep 08 2001 Martin Stjernholm * cc-cmds.el (c-indent-region): Did a speedup made possible by the more flexible state cache. * cc-engine.el (c-parse-state, c-whack-state-before, c-whack-state-after, c-hack-state, c-narrow-out-enclosing-class, c-guess-basic-syntax): Improved the state cache system. It now can use partial info from an old cached state to calculate a new one at a different position. Removed some kludges to avoid the state cache. The new functions `c-whack-state-before' and `c-whack-state-after' replace the now obsolete `c-whack-state'. * cc-engine.el (c-beginning-of-statement-1): Optimized backing through a macro. This can speed things up quite a bit when there are long macros before point. (c-beginning-of-macro): Do not ignore the limit. Sun Sep 02 2001 Martin Stjernholm * cc-cmds.el (c-electric-continued-statement): Fixed a bug where the keyword wasn't reindented correctly if followed by another keyword or identifier. * cc-engine.el (c-parse-state): Ignore closed brace pairs that are in macros. Fixes some cases where e.g. the second of two "do { } while (0)" macros after each other indented differently. Fri Aug 31 2001 Martin Stjernholm * cc-engine.el (c-beginning-of-macro, c-forward-syntactic-ws): Recognize "#!" as a preprocessor directive when it begins a line, to allow for script interpreter lines like "#!/usr/bin/pike" at the beginning of the file. Thu Aug 30 2001 Martin Stjernholm * cc-engine.el (c-looking-at-inexpr-block): Recognize brace blocks inside a parenthesis expression as inexpr-statement. Useful when writing statements as macro arguments. Sat Aug 25 2001 Martin Stjernholm * cc-cmds.el (c-fill-paragraph, c-do-auto-fill, c-mask-comment): Broke out the comment masking code from `c-fill-paragraph' to a new function `c-mask-comment', to be able to do the same thing in `c-do-auto-fill'. This should make auto-fill-mode behave better. Mon Aug 20 2001 Martin Stjernholm * cc-cmds.el (c-electric-brace, c-electric-paren): Check `executing-macro' to avoid blinking parens when macros are executed. * cc-mode.el, cc-styles.el (c-setup-filladapt): Moved from cc-mode.el to cc-styles.el for consistency with `c-setup-paragraph-variables' (which was placed there due to the dependency from `c-set-style'). * cc-styles.el, cc-vars.el: Fixed bug with incomplete initialization from the style variable fallbacks if there already is a style called "user" defined when CC Mode starts up for the first time. Fri Aug 17 2001 Martin Stjernholm * cc-cmds.el, cc-vars.el (c-comment-indent, c-indent-comment-alist): Added new variable `c-indent-comment-alist' to allow better control over `c-comment-indent'. Tue Aug 14 2001 Martin Stjernholm * cc-align.el (c-lineup-C-comments): Try to match both `comment-start-skip' and the comment prefix on the current line with the comment starter, so that we line up comments which matches `c-comment-prefix-regexp' on the first line (after the `/') without the need to make `comment-start-skip' match whatever `c-comment-prefix-regexp' matches. * cc-mode.el, cc-styles.el (c-common-init, c-set-style-1, c-setup-paragraph-variables): Moved the variable initialization based on `c-comment-prefix-regexp' to a new function `c-setup-paragraph-variables', which is now used both at mode init and when a style that sets `c-comment-prefix-regexp' is activated. Sat Aug 11 2001 Martin Stjernholm * cc-engine.el (c-beginning-of-member-init-list): Better handling of C++ template args to avoid confusion with `<' and `>' used as operators in member init expressions. Wed Jul 25 2001 Martin Stjernholm * cc-engine.el (c-most-enclosing-brace, c-least-enclosing-brace): Added optional second arg to limit the search to before a certain point. * cc-engine.el (c-guess-basic-syntax): Fixed bug which could cause incorrect analysis if a cached state is used (usually only happens when an electric key reindents a line). Tue Jul 24 2001 Martin Stjernholm * cc-defs.el (c-forward-comment): More idiosyncrasy insulation. This time for XEmacs 21. * cc-engine.el, cc-langs.el: Improved handling of inheritance lists: (c-beginning-of-inheritance-list): Rewritten to use a more syntactically correct method that doesn't get confused by badly placed linebreaks and comments. (c-guess-basic-syntax): Several fixes to the handling of inheritance lists in combination with templates. 'inher-intro is now anchored on the start of the class declaration and not the indentation of the current line. Switched places on cases 5D.3 and 5D.4 and made them use more syntactically correct methods. (c-inher-key): Removed since the code in `c-guess-basic-syntax' now uses token-based search. * cc-cmds.el, cc-mode.el (c-mode-menu): Added a submenu to access some toggles. (c-toggle-syntactic-indentation): New function to toggle the variable `c-syntactic-indentation'. * cc-styles.el (c-set-style): Improved the error message for incorrect offsets a bit. Mon Jul 23 2001 Martin Stjernholm * cc-cmds.el (c-indent-exp): Don't require that the sexp follows point immediately, instead find the closest following open paren that ends on another line. Sat Jul 21 2001 Martin Stjernholm * cc-align.el (c-lineup-cascaded-calls): New indentation function. * cc-engine.el (c-beginning-of-macro): Bugfix for directives with whitespace between the '#' and the name. * cc-mode.texi: Rearranged the indentation functions in alphabetic order. Documented c-lineup-cascaded-calls. Fri Jul 20 2001 Martin Stjernholm * cc-engine.el (c-forward-syntactic-ws, c-backward-syntactic-ws): Handle line continuations as whitespace. Don't move past a macro if that'd take us past the limit. Wed Jul 11 2001 Martin Stjernholm * cc-engine.el (c-beginning-of-macro, c-forward-syntactic-ws): Multiline strings begin with `#"' in Pike, and that shouldn't be confused with a preprocessor directive. Mon Jul 09 2001 Martin Stjernholm * cc-cmds.el: Extended the kludge to interoperate with the delsel and pending-del packages wrt to the new function `c-electric-delete-forward'. Fri Jul 06 2001 Martin Stjernholm * cc-cmds.el (c-indent-exp): Keep the indentation of the block itself, i.e. only indent the contents in it. * cc-styles.el (c-set-style): Use the default argument to completing-read instead of initial-contents, if the function is recent enough to support it. Mon Jun 11 2001 Martin Stjernholm * cc-mode.el (c-mode-help-address): Removed bug-gnu-emacs@gnu.org from the receiver list for bug reports. I've almost never seen a bug reported this way that should go to that list, but it's rather common that the reports concern the combination CC Mode and XEmacs instead. Sun Jun 10 2001 Martin Stjernholm * cc-cmds.el (c-electric-paren): Fixed bug when both brace-elseif-brace and brace-catch-brace are active and there's a "else if"-block before the catch block. * cc-menus.el (cc-imenu-c++-generic-expression): Detect function headers that span lines. Sat May 12 2001 Martin Stjernholm * cc-cmds.el (c-electric-brace, c-electric-semi&comma, c-electric-colon, c-electric-paren): Check for last on line only for doing the auto-newline-mode stuff, not for the reindentation. * cc-cmds.el (c-electric-brace): Fixed bugs in the handling of c-syntactic-indentation: When it's nil, indent the new lines but don't reindent the current one. Reindent the line only when the inserted brace comes first on it, instead of last. * cc-cmds.el (c-electric-brace, c-electric-semi&comma): Fixed two places where c-syntactic-indentation wasn't heeded. * cc-cmds.el (c-electric-pound): Don't be electric inside a macro. * cc-engine.el (c-backward-to-start-of-if): Try a little harder to find a fallback position when an orphan else is found. Fixed case where an else following a do-while statement could be associated with an if inside the do-while. Fri May 11 2001 Martin Stjernholm * cc-cmds.el (c-guess-fill-prefix): Tuned the dwim for the fallback to add a single space after the comment prefix. * cc-cmds.el (c-indent-new-comment-line): Somewhat better behavior in some special cases, especially for single-line comments. Avoid breaking up a comment starter or ender. Sat May 05 2001 Martin Stjernholm * cc-cmds.el (c-outline-level): Applied patch from the Emacs sources to make this work in invisible text. * cc-langs.el (c-switch-label-key): Fixed regexp to not be confused by a later ':' on the same line as the label. Wed May 02 2001 Martin Stjernholm * cc-cmds.el, cc-mode.el (c-electric-delete, c-electric-delete-forward): Split `c-electric-delete' into two functions where `c-electric-delete-forward' always deletes forward and `c-electric-delete' only contains the code necessary for XEmacs to choose between backward and forward deletion. `c-electric-delete-forward' is now bound to C-d to get the electric behavior on that key too. * cc-mode.texi: Updated the doc for hungry-delete mode wrt the Backspace/Delete key handling. Also incorporated a small clarification from the Emacs people. Wed Mar 14 2001 Martin Stjernholm * cc-cmds.el (c-fill-paragraph): Fixed bogus direct use of c-comment-prefix-regexp, which caused an error when it's a list. Sun Feb 25 2001 Martin Stjernholm * Release 5.28 Sun Feb 25 2001 Martin Stjernholm * cc-mode.el, cc-vars.el (c-common-init, c-default-style): Removed the hardcoded switch to "java" style in Java mode. It's instead taken care of by the default value for c-default-style. * cc-mode.texi: Documented the electric keyword feature. Updated the mentions of the "java" style special case for Java mode. Sat Feb 24 2001 Martin Stjernholm * cc-align.el (c-lineup-math): Fix bug where lineup was triggered by equal signs in string literals. Sun Feb 25 2001 Martin Stjernholm * cc-mode.el, cc-vars.el (c-common-init, c-default-style): Removed the hardcoded switch to "java" style in Java mode. It's instead taken care of by the default value for c-default-style. * cc-mode.texi: Updated the mentions of the "java" style special case for Java mode. Sat Feb 24 2001 Martin Stjernholm * cc-align.el (c-lineup-math): Fix bug where lineup was triggered by equal signs in string literals. Wed Feb 21 2001 Martin Stjernholm * cc-cmds.el (c-fill-paragraph): Fixed bug in the paragraph limit detection when at the ends of the buffer. * cc-engine.el (c-guess-basic-syntax): Removed bogus check for "for" statement clause in case 7F; a better one is done earlier in case 7D anyway. Tue Feb 20 2001 Martin Stjernholm * cc-cmds.el (c-guess-fill-prefix): Improved the heuristics somewhat more and did a small optimization. Mon Feb 19 2001 Martin Stjernholm * cc-cmds.el (c-beginning-of-statement, c-end-of-statement): Use the limit argument only to limit the syntactic context search, not to limit the actual movement. * cc-cmds.el (c-beginning-of-statement): Move by sentence inside multiline strings, just like in comments. Also various fixes to the paragraph and comment prefix recognition, block comment ender handling etc. Sun Feb 18 2001 Martin Stjernholm * cc-cmds.el (c-fill-paragraph): Take more care to preserve the relative position of the point. * cc-cmds.el (c-electric-continued-statement): New function to use as abbrev hook to reindent for keywords such as "else" that continues an earlier statement. * cc-menus.el (cc-imenu-c++-generic-expression): Treat structs like classes. * cc-mode.el (c-mode, c++-mode, java-mode, objc-mode, pike-mode): Populate the default abbrev tables to reindent for keywords such as "else" that can continue earlier statements. Abbrev mode is therefore turned on by default now. (Note that this doesn't apply to idl-mode, since IDL afaik doesn't have statements at all.) Wed Feb 14 2001 Martin Stjernholm * cc-engine.el (c-inside-bracelist-p): Fix for handling bracelists where the declaration contains template arguments. Fri Feb 09 2001 Martin Stjernholm * cc-cmds.el (c-comment-indent): Use `c-get-syntactic-indentation' to correctly calculate the syntactic indentation. Fixes bug with lineup functions that return vectors. * cc-engine.el (c-get-syntactic-indentation): Split the indentation sum calculation from `c-indent-line' to a separate function. Mon Feb 05 2001 Martin Stjernholm * cc-cmds.el (c-beginning-of-statement, c-comment-indent): Fixed places where it was assumed that preprocessor directives have to start in column zero. * cc-engine.el (c-beginning-of-member-init-list): Handle C++ template arguments after a class identifier properly. * cc-engine.el (c-guess-basic-syntax): Treat initializer brace lists for `new Foo[]' constructs in Java as expressions and not top level definition brace lists on the top level, so that they'll get indented consistently with the same type of expression in a normal block. Sat Feb 03 2001 Martin Stjernholm * cc-cmds.el (c-fill-paragraph): The kludge that checks whether the adaptive filling package fails to keep the comment prefix is now kludged further to check for filladapt-mode which doesn't have that problem. This is really icky, but it's the only way that works with the current misfeatures/bugs in both adaptive-fill-mode and filladapt-mode. * cc-cmds.el (c-fill-paragraph): Made the way the paragraph around point is recognized more robust. Sun Jan 21 2001 Martin Stjernholm * cc-cmds.el, cc-engine.el, cc-lobotomy.el (c-state-cache, c-in-literal-cache, c-auto-fill-prefix, c-lit-limits, c-lit-type): Fixed all internal variables used dynamically so that they are always bound. * cc-cmds.el, cc-engine.el: Improved recovery of syntactic errors: (c-indent-region): Fixed reporting of syntactic errors so that the region is fully reindented even when an error occurs. The last syntactic error is printed afterwards. Also cleanup up a whole lot of code that tried to optimize indentation of whole sexps but in reality accomplishes nothing. (c-indent-sexp): Use c-indent-region. (c-parsing-error): Changed this variable to hold the message for any syntactic error that is discovered. (c-parse-state): Search backward from point instead of the bod position when the latter is invalid. This makes CC Mode recover faster when there are unbalanced close braces. (c-backward-to-start-of-if): Use c-parsing-error to report dangling "else" clauses instead of throwing an error, and fall back to a reasonable position. (c-indent-line): Added argument to avoid reporting syntactic errors. (c-show-syntactic-information): Don't report any syntactic errors. Wed Jan 17 2001 Martin Stjernholm * cc-cmds.el (c-beginning-of-statement): Fixed bugs with paragraph recognition when moving by sentence in literals. * cc-langs.el (c-Java-javadoc-paragraph-start): Modified paragraph start regexp for javadoc to recognize javadoc markup in general instead of a specific set of keywords, to be more future-safe. (c-Pike-pikedoc-paragraph-start, c-Pike-pikedoc-paragraph-separate): New regexps to recognize pikedoc markup. * cc-mode.el: Fixed initialization and use of c-current-comment-prefix. (pike-mode): Initialize paragraph settings pikedoc recognition. * cc-vars.el (c-default-style): Made a nicer Customize widget. (c-comment-prefix-regexp): Made it possible to use an association list on this to specify mode specific regexps. The default value now use a special regexp in Pike mode to recognize pikedoc markup. (c-current-comment-prefix): New variable containing the actual regexp from c-comment-prefix-regexp for the current buffer. Sun Jan 14 2001 Martin Stjernholm * cc-cmds.el (c-electric-brace): Fixed check for special brace lists: We can't look at the syntax, since a brace list can get recognized as a plain statement-cont. * cc-engine.el (c-guess-basic-syntax): Fixed bug where a special brace list opener broken over two lines got recognized as a statement on the second line. Case 9A changed. Mon Jan 08 2001 Martin Stjernholm * cc-cmds.el (c-electric-brace): Fixed bug in c-state-cache adjustment after line is reindented. Wed Dec 27 2000 Martin Stjernholm * cc-defs.el (c-point): Added optional argument for position to use instead of the current point. * cc-defs.el, cc-engine.el (c-add-class-syntax): Do not add the in-expression block symbols when the construct starts at boi, to avoid the extra level of indentation in that case. Cases 4, 16A and 17E affected. Sun Nov 26 2000 Martin Stjernholm * cc-cmds.el: Use `indent-according-to-mode' instead of direct calls to `c-indent-line', to adhere better to Emacs conventions. * cc-engine.el (c-indent-line): Use the syntax already bound to `c-syntactic-context', if there is any. Sun Nov 19 2000 Martin Stjernholm * cc-engine.el (c-get-offset): Fixed bug where the indentation wasn't added up correctly when a lineup function returned nil. Fri Nov 17 2000 Martin Stjernholm * cc-engine.el (c-collect-line-comments): Fixed bug where empty lines were ignored when collecting line comments backwards. Sun Oct 08 2000 Martin Stjernholm * cc-align.el (c-lineup-dont-change): Return an absolute indentation column to work correctly in the case when several syntactic elements are processed for the same line. * cc-engine.el, cc-styles.el, cc-vars.el (c-evaluate-offset, c-get-offset, c-indent-line, c-valid-offset, c-read-offset, c-set-offset): Added absolute indentation column settings by using the vector type. * cc-mode.texi: Documented the new vector setting for offsets. Mon Oct 02 2000 Martin Stjernholm * cc-cmds.el, cc-vars.el (c-electric-paren, c-cleanup-list): Implemented two new cleanups `space-before-funcall' and `compact-empty-funcall'. * cc-mode.texi: Documented the two new cleanups space-before-funcall and compact-empty-funcall on c-cleanup-list. Sun Oct 01 2000 Martin Stjernholm * cc-defs.el (c-paren-re, c-identifier-re): Two new macros for helping building regexps. * cc-engine.el (c-on-identifier): New function for detecting identifiers. It takes keywords into account. * cc-langs.el, cc-mode.el: Added regexps for complete keyword lists. `c-keywords' is set to a regexp matching all keywords in the current language. Tue Sep 26 2000 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Added '#' to the list of characters to skip backwards over at the beginning of a statement, since it can precede string literals in Pike. Thu Aug 31 2000 Martin Stjernholm * cc-cmds.el (c-guess-fill-prefix): Fixed bug with prefix recognition when standing on the last line in a C++ comment with nothing but whitespace after the prefix. * cc-engine.el (c-backward-to-start-of-if): Fixed bug when given no limit argument. Wed Aug 30 2000 Martin Stjernholm * cc-engine.el (c-inside-bracelist-p): Fixed brace list recognition for the `[]= operator symbol in Pike. Sat Aug 26 2000 Martin Stjernholm * cc-bytecomp.el (cc-eval-when-compile): New macro that works around a bug in `eval-when-compile' in the byte compiler. * cc-engine.el (c-forward-token-1): Fixed bug with return value when count is zero and there's no token start within the limit. (c-guess-basic-syntax): Don't add 'comment-intro to lines with "prefix comments", i.e. comments which are followed by code on the same line. * cc-mode-19.el: Fixes so that checks that must be done at compile time also are done then. Fri Aug 25 2000 Martin Stjernholm * cc-defs.el: Make sure cc-mode-19 is loaded both at compile time and at runtime, and only when it's needed. Sun Aug 20 2000 Martin Stjernholm * Major cleanup for less error prone and more warning free compilation, including some fixes for bugs due to different compilation orders. Thanks to Martin Buchholz for providing the basis for all this. cc-bytecomp.el: New file that provides some byte compilation features: It ensures that files always are loaded from the current source directory during compilation, and it provides a set of macros to turn off specific compiler warnings for specific symbols. (It's not CC Mode specific in any way.) Fixed a nearly acyclic dependency tree (both runtime and compile-time) between all files. cc-defs.el: Separated all macros before the inline functions, to ensure correct compilation. cc-defs.el, cc-engine.el: Moved c-beginning-of-macro to from cc-defs.el to cc-engine.el and made it a function instead. cc-mode-19.el: Patch the byte compiler in Emacs 19 not to warn about char-after. cc-vars.el: Cope even when there isn't a custom package containing defcustom available. cc-make.el: Removed since it's no longer necessary. README: Updated installation instructions. Mon Aug 14 2000 Martin Stjernholm * cc-cmds.el, cc-langs.el, cc-mode.el: Moved around things to improve the modularity: Moved all mode init stuff from cc-langs.el to cc-mode.el, including the keymap initialization; cc-langs now only contains the various variables for configuring the language syntax. * cc-engine.el, cc-styles.el (c-evaluate-offset, c-get-offset): Moved from cc-styles to cc-engine since file dependency analysis suggests they belong there (which also makes more sense). Thanks to Martin Buchholz for doing the analysis. Sat Aug 12 2000 Martin Stjernholm * cc-cmds.el (c-fn-region-is-active-p): New function that wraps the corresponding macro, for use in places that aren't compiled. Thanks to Martin Buchholz for pointing out this. * cc-langs.el (c-mode-menu): Use c-fn-region-is-active-p. * cc-mode.el (c-prepare-bug-report-hooks): Hook variable to add things to the bug report. Mon Aug 07 2000 Martin Stjernholm * cc-cmds.el (c-guess-fill-prefix): Fixed bug where the returned prefix could contain a newline when the search for a good prefix line failed. Sun Aug 06 2000 Martin Stjernholm * cc-cmds.el (c-toggle-auto-state, c-toggle-hungry-state, c-toggle-auto-hungry-state): Made the argument optional, as the documentation says it is. Sat Aug 05 2000 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Don't treat the Pike multiline string syntax, #"...", as a cpp macro. Mon Jul 10 2000 Martin Stjernholm * Release 5.27 Sun Jul 09 2000 Martin Stjernholm * cc-engine.el (c-looking-at-inexpr-block): Replaced a call to c-beginning-of-statement-1 that caused a bad case of recursion which could consume a lot of CPU in large classes in languages that have in-expression classes (i.e. Java and Pike). * cc-engine.el (c-guess-basic-syntax): Check for in-expression statements before top level constructs (i.e. case 6 is moved before case 5 and is now case 4) to catch in-expression classes in top level expressions correctly. Sun Jul 02 2000 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Less naive handling of objc-method-intro. Case 4 removed and case 5I added. * cc-langs.el (c-append-paragraph-start): New variable used by c-common-init to get paragraph-start correct. * cc-langs.el (c-common-init): Use c-append-paragraph-start to initialize paragraph-start to make it correct both with and without the javadoc special case. * cc-mode.el (java-mode): Use c-append-paragraph-start to initialize paragraph-start for javadoc markup. * cc-vars.el (c-style-variables-are-local-p): Incompatible change by defaulting this to t. It's motivated by the confusing behavior that otherwise arise from the style system when editing both java and non-java files at the same time (see the comments about style setting in c-common-init). Tue Jun 20 2000 Martin Stjernholm * cc-cmds.el (c-indent-new-comment-line): Added a kludge similar to the one in c-fill-paragraph to check the fill prefix from the adaptive fill function for sanity. Mon May 01 2000 Martin Stjernholm * cc-defs.el (c-end-of-defun-1): Fixed forward scanning into defun block. Sun Mar 19 2000 Martin Stjernholm * cc-mode.texi Documented the change of cpp-macro. Tue Mar 14 2000 Martin Stjernholm * cc-align.el (c-lineup-multi-inher): Handle lines with leading comma nicely. Extended to handle member initializers too. * cc-engine.el (c-beginning-of-inheritance-list, c-guess-basic-syntax): Fixed recognition of inheritance lists when the lines begins with a comma. * cc-mode.texi Updated doc for c-lineup-multi-inher. * cc-vars.el (c-offsets-alist): Changed default for member-init-cont to c-lineup-multi-inher since it now handles member initializers and indents better for leading commas. Sun Mar 12 2000 Martin Stjernholm * cc-cmds.el (c-electric-brace): Fixed some bugs in the state handling that caused class open lines to be recognized as statement-conts in some cases. * cc-cmds.el (c-indent-new-comment-line): Keep the fill prefix guessed by the adaptive fill function unless point is on the first line of a block comment. * cc-engine.el (c-forward-syntactic-ws): Fixed an infloop bug when the buffer ends with a macro continuation char. * cc-engine.el (c-guess-basic-syntax): Added support for function definitions as statements in Pike. The first statement in a lambda block is now labeled defun-block-intro instead of statement-block-intro. * cc-engine.el (c-narrow-out-enclosing-class): Whack the state so that the class surrounding point is selected, not the one innermost in the state. * cc-engine.el (c-guess-basic-syntax): Fixed bug in recognition of switch labels having hanging multiline statements. * cc-engine.el (c-beginning-of-member-init-list): Broke out some code in c-guess-basic-syntax to a separate function. * cc-engine.el (c-just-after-func-arglist-p): Fixed recognition of member inits with multiple line arglists. * cc-engine.el (c-guess-basic-syntax): New case 5B.3 to detect member-init-cont when the commas are in funny places. Thu Mar 09 2000 Martin Stjernholm * cc-defs.el (c-auto-newline): Removed this macro since it's not used anymore. * cc-engine.el (c-looking-at-bos): New helper function. * cc-engine.el (c-looking-at-inexpr-block): More tests to tell inexpr and toplevel classes apart in Pike. * cc-engine.el (c-guess-basic-syntax): Fixed bogus recognition of case 9A. * cc-langs.el, cc-mode.el (c-Pike-inexpr-class-key): New constant, since "class" can introduce an in-expression class in Pike nowadays. Sun Feb 06 2000 Martin Stjernholm * cc-align.el (c-gnu-impose-minimum): Don't impose minimum indentation on cpp-macro lines. * cc-engine.el (c-guess-basic-syntax): Made the cpp-macro a syntax modifier like comment-intro, to make it possible to get syntactic indentation for preprocessor directives. It's incompatible wrt to lineup functions on cpp-macro, but it has no observable effect in the 99.9% common case where cpp-macro is set to -1000. Sat Feb 05 2000 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed bug with missed member-init-cont when the preceding arglist is several lines.

Sun Jan 09 2000 Martin Stjernholm * cc-cmds.el (c-indent-command): Obey c-syntactic-indentation. * cc-cmds.el (c-electric-brace, c-electric-slash, c-electric-star, c-electric-semi&comma, c-electric-colon, c-electric-lt-gt, c-electric-paren): Don't reindent old lines when c-syntactic-indentation is nil. * cc-engine.el (c-beginning-of-statement-1): Fixed bug where we were left at comments preceding the first statement when reaching the beginning of the buffer. * cc-vars.el (c-syntactic-indentation): New variable to turn off all syntactic indentation. Tue Dec 28 1999 Martin Stjernholm * cc-cmds.el (c-fill-paragraph): Keep one or two spaces between the text and the block comment ender when it hangs, depending on how many there are before the fill. Sun Dec 19 1999 Martin Stjernholm * cc-engine.el (c-beginning-of-closest-statement): New helper function to go back to the closest preceding statement start, which could be inside a conditional statement. * cc-engine.el (c-guess-basic-syntax): Use c-beginning-of-closest-statement in cases 10B.2, 17B and 17C. * cc-engine.el (c-guess-basic-syntax): Better handling of arglist-intro, arglist-cont-nonempty and arglist-close when the arglist is nested inside parens. Cases 7A, 7C and 7F changed. * cc-langs.el (c-Java-javadoc-paragraph-start): Brought up-to-date with javadoc 1.2. Fri Dec 17 1999 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Fixed handling of multiline Pike type decls. Tue Dec 14 1999 Martin Stjernholm * cc-cmds.el (c-indent-new-comment-line): Always break multiline comments in multiline mode, regardless of comment-multi-line. Mon Dec 13 1999 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed bug with fully::qualified::names in C++ member init lists. Preamble in case 5D changed. Sat Dec 04 1999 Martin Stjernholm * cc-langs.el (c-common-init): Handling of obsolete variables moved to c-initialize-cc-mode. More compatible style override when using global style variables. * cc-mode.el (c-initialize-cc-mode): Handling of obsolete variables moved here. * cc-mode.texi Documented the special behavior of c-special-indent-hook as a style variable. Don't talk about doing (c-make-styles-buffer-local t) in a mode hook, since that's already too late to work right. * cc-styles.el (c-make-styles-buffer-local): Flag style variable localness in c-style-variables-are-local-p to make the compatibility measure in c-common-init work well. * cc-styles.el (c-set-style-1): c-special-indent-hook can no longer contain set-from-style. * cc-styles.el (c-initialize-builtin-style): Don't check for set-from-style on c-special-indent-hook. * cc-styles.el (c-copy-tree): Obsolete. The standard function copy-alist is sufficient now. * cc-styles.el (c-set-style, c-set-style-1, c-get-style-variables): Fixes to variable initialization so that duplicate entries in styles have the same effect regardless of DONT-OVERRIDE. * cc-styles.el (c-set-style-2): Fixed bug where the initialization of inheriting styles failed when the dont-override flag is set. * cc-vars.el (c-special-indent-hook): Don't use set-from-style on this. Mon Nov 22 1999 Martin Stjernholm * cc-defs.el (c-forward-comment): Removed the workaround introduced in 5.38 since it had worse side-effects. If a line contains the string "//\"", it regarded the // as a comment start since the \ temporarily doesn't have escape syntax. Sun Nov 21 1999 Martin Stjernholm * Release 5.26 Sun Nov 21 1999 Martin Stjernholm * cc-cmds.el (c-forward-conditional): Handle an arbitrary target depth. Optionally count #else lines as clause limits, as suggested by don provan . #elif handling fixed. * (c-up-conditional-with-else, c-down-conditional, c-down-conditional-with-else): New commands that uses the added functionality in `c-forward-conditional'. * cc-mode.texi: Documented the new up/down preprocessor conditional function varieties. Tue Nov 09 1999 Martin Stjernholm * cc-mode.texi: Updated for all the new features and proofread. Major changes: o All text filling and line breaking issues is collected in a new top-level chapter. The section on auto-fill mode interaction have been incorporated into this. o The list of the standard lineup functions is expanded with better explanations and examples. It's moved to a top-level chapter since it's hard to find under Customizing Indentation / Advanced Customizations / Custom Indentation Functions. o The sections on Permanent Customization and Styles are mostly rewritten due to the changes in the style system. The part about the mode hooks has gotten an own section. Tue Oct 26 1999 Martin Stjernholm * cc-align.el (c-lineup-comment): Preserve the alignment with a comment on the previous line instead of preserving the comment-column. Sun Sep 26 1999 Martin Stjernholm * Fixes to IDL mode after input from Eric Eide : * cc-engine.el (c-beginning-of-statement-1): Allow `c-conditional-key' to be nil, for the benefit of IDL mode. * cc-engine.el (c-guess-basic-syntax): Ditto. cc-langs.el (C-IDL-class-key): Fixed. Don't match `class' but do match CORBA 2.3 `valuetype'. * cc-langs.el (c-IDL-access-key): New defconst. Should be nil for IDL. * cc-langs.el (c-IDL-conditional-key): New defconst. Should be nil for IDL. * cc-langs.el (c-IDL-comment-start-regexp): New defconst. Like C++. * cc-mode.el (idl-mode): Use new `c-IDL-*' defconsts. Also, set `c-method-key' and `c-baseclass-key' to nil.

Use c-comment-prefix-regexp and comment-start-skip instead of hardcoded regexps. Sat Aug 14 1999 Martin Stjernholm * cc-cmds.el (c-beginning-of-defun, c-end-of-defun): Fixed eob behavior and return value as documented. Sat Jul 31 1999 Martin Stjernholm * Changes for new style variable init system: * cc-langs.el (c-common-init): Dito. * cc-styles.el: c-offsets-alist moved to cc-vars.el since it's now customizable. * cc-vars.el: Style variables may now take a value 'set-from-style to make them take their value from the style system. This value is now the default on all these variables. * cc-vars.el (c-valid-offset): New function to verify a syntactic symbol offset setting. * cc-vars.el (c-offsets-alist): Variable moved from cc-styles.el since it's now customizable in a similar way to the other style variables. * cc-vars.el (c-old-style-variable-behavior): New variable to revert to the old style init behavior. * cc-vars.el (c-hanging-comment-starter-p, c-hanging-comment-ender-p): These variables are now obsolete and therefore removed. * cc-vars.el (c-file-style, c-file-offsets): Made always buffer local. * cc-menus.el (cc-imenu-c++-generic-expression): Don't match the throws clause that might follow the function prototype in C++. Sat Jul 24 1999 Martin Stjernholm * cc-defs.el (c-beginning-of-macro): Fixed bug where point could move forward for macros that doesn't start in column 0. Thu Jul 08 1999 Martin Stjernholm * cc-align.el (c-indent-multi-line-block, c-lineup-whitesmith-in-block): Two new lineup functions for use in whitesmith style. * cc-styles.el (c-style-alist): More fixes to whitesmith style. It should now handle all different braces uniformly in both hanging and non-hanging cases. Wed Jul 07 1999 Martin Stjernholm * cc-mode.texi: Documented the default behavior when a symbol doesn't exist on c-hanging-braces-alist. Mon Jul 05 1999 Martin Stjernholm * cc-cmds.el (c-indent-exp): Use a marker to save point to make it stay in the same position relative to the surrounding text. * cc-cmds.el (c-fill-paragraph): Force the line comment prefix when adaptive-fill-mode doesn't manage to get it correct. * cc-menus.el (cc-imenu-java-generic-expression): Handle types with dotted notation, e.g. foo.bar.Gnu. * cc-mode.el (c-initialize-cc-mode): Wrap all function calls within unwind-protect (previously only some were wrapped so it would be possible to register mode initialization when full initialization did not finish). * cc-styles.el (c-style-alist): Corrected the brace placement in the whitesmith style. Thanks to Sean Luke . Also extended the bsd and whitesmith styles with consistent brace placement for all constructs. Sun Jul 04 1999 Martin Stjernholm * cc-cmds.el (c-context-line-break): Continue C++ comments too when point is in the middle of them. * cc-cmds.el: Line breaking and paragraph filling code rewritten: (c-guess-fill-prefix): New function that uses various heuristics to guess the comment prefix. (c-fill-paragraph): Rewritten to use `c-guess-fill-prefix'. It now assumes adaptive filling is active to preserve the line prefix inside comments. (c-indent-new-comment-line): Replacement for the now obsolete `c-comment-line-break-function' that uses `c-guess-fill-prefix' when appropriate. It now observes the setting of `comment-multi-line', which has effect in C-style block comments. * cc-cmds.el (c-context-line-break): New function intended to be put on RET. It's essentially `newline-and-indent', but continues C block comments with the appropriate line prefix. * cc-cmds.el (c-do-auto-fill): New function put on `normal-auto-fill-function' to implement the `c-ignore-auto-fill' variable. * cc-cmds.el (c-beginning-of-statement): Use `c-comment-prefix-regexp' to avoid ending up inside the comment prefix. Better handling of comment starters and enders. Catch comments better when traversing code. Stop at preprocessor directives. * cc-defs.el (c-forward-comment): New subst to hide platform dependent quirks in `forward-comment'. * cc-engine.el (c-literal-limits): Added NOT-IN-DELIMITER argument. (c-literal-limits-fast): Implemented NEAR and NOT-IN-DELIMITER arguments. Activate this function by default when `parse-partial-sexp' supports it (currently Emacs 20.x). * cc-engine.el (c-guess-basic-syntax): Anchor the `c' syntax on the comment opener to make constants usable as lineup arguments. * cc-align.el (c-lineup-C-comments): Fixes to handle the changed anchor position in the `c' syntactic symbol. Handle more than stars in the comment prefix; use the new variable `c-comment-prefix-regexp'. Don't indent text not preceded by a comment prefix to the right of the comment opener if it's long. * cc-langs.el: Fixes to mode initialization for new line breaking and paragraph filling method. Adaptive fill mode is now activated at startup instead of deactivated. The variables used for adaptive filling and paragraph movement are also changed to incorporate the value of `c-comment-prefix-regexp'. `substitute-key-definition' is used to override some functions in the global map instead of overriding their default bindings. * cc-mode.el (java-mode): Modify `paragraph-start' for the javadoc markup at mode init. * cc-mode.el (c-setup-filladapt): A new convenience function to configure Kyle E. Jones' Filladapt mode for CC Mode. This function is intended to be used explicitly by the end user only. * cc-vars.el (c-comment-prefix-regexp): New variable used to recognize the comment fill prefix inside comments. (c-block-comment-prefix): New name for `c-comment-contiuation-stars', which is now obsolete. It's generalized to handle any character sequence. (c-ignore-auto-fill): New variable used to selectively disable Auto Fill mode in specific contexts. Tue Jun 29 1999 Martin Stjernholm * cc-cmds.el (c-comment-indent): Leave at least one space between the comment and the last nonblank character in the case where we look at the indentation of the comment on the previous line (case 4). * cc-engine.el (c-beginning-of-statement-1): Added ``' to the list of characters that may start a statement (it's a sort of prefix operator in Pike, and isn't used at all in any of the other languages). Tue Jun 15 1999 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Report brace list opens inside continued statements as statement-cont instead of brace-list-open. The reason is that one normally adjusts brace-list-open for brace lists as top-level constructs, and brace lists inside statements is a completely different context. Case 10B.2 changed. Also changed (the somewhat esoteric) case 9A to cope with this. Sat May 29 1999 Martin Stjernholm * cc-cmds.el (c-electric-brace): Added electric handling of the open brace for brace-elseif-brace. Thu May 27 1999 Martin Stjernholm * cc-defs.el (c-with-syntax-table): New macro to easily switch syntax tables temporarily. * cc-engine.el (c-guess-basic-syntax): Handle template and member init argument lists split over several lines.

Mon May 03 1999 Martin Stjernholm * cc-align.el (c-lineup-template-args): Handle nested template arglists. * cc-langs.el (c++-template-syntax-table): New syntax table that makes `<' and `>' parenthesis characters, which is useful to switch to temporarily when analyzing template arglists. * cc-styles.el: Changed default alignment of labels in the java style to conform to the examples in the Java Language Specification. * cc-styles.el (c-offsets-alist): Use `c-lineup-template-args' by default. Fri Mar 12 1999 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Pike allows a comma immediately before the closing paren in an arglist, so don't check that in Pike mode. Case 7A changed. Sat Mar 06 1999 Martin Stjernholm * cc-cmds.el (c-indent-region): Fixed bug where comment-only lines were ignored under certain conditions. Fri Mar 05 1999 Martin Stjernholm * cc-align.el (c-lineup-template-args): New function for aligning continued template argument lists. * cc-engine.el (c-guess-basic-syntax): Fix for member init lists containing function arglists split over several lines. Case 5D.1 changed. * cc-engine.el (c-guess-basic-syntax): Fixed bug where template-args-cont didn't get recognized when the first arglist opener line doesn't contain a template argument. New case 5K. Sat Feb 27 1999 Martin Stjernholm * cc-defs.el (c-point): Changed from subst to macro for efficiency. (c-beginning-of-defun-1, c-end-of-defun-1): New beginning-of-defun/end-of-defun wrappers separated from c-point. * cc-menus.el (imenu-generic-expression, imenu-case-fold-search, imenu-progress-message): Dummy definitions to avoid compiler warnings if imenu can't be loaded. * cc-menus.el (cc-imenu-init): New function called at mode init. * cc-mode.el (c-mode, c++-mode, objc-mode, java-mode): Moved imenu initializations to cc-imenu-init. Sun Feb 21 1999 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Slightly better check for lambda-intro-cont in Pike mode. Case 6 changed. * cc-engine.el (c-looking-at-inexpr-block): Fixed bug where anything following "new Foo()" was considered an anonymous class body in Java mode. Fri Feb 12 1999 Barry A. Warsaw * cc-cmds.el (c-comment-line-break-function): When breaking in a string, don't insert a new line. Sun Jan 31 1999 Barry A. Warsaw * cc-engine.el (c-at-toplevel-p): New interface function which returns information useful to add-on authors. It tells you whether you're at a toplevel statement or not. Tue Dec 22 1998 Barry A. Warsaw * cc-cmds.el (c-comment-line-break-function): It is possible that forward-line does not land us at the bol, say if we're on the last line in a file. In that case, do a back-to-indentation instead of a forward-comment -1. Fri Dec 11 1998 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Don't catch "default:" as normal label in case 4. Thu Dec 10 1998 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Use c-bitfield-key to recognize continued bitfield declarations. Case 5D.1 changed. * cc-langs.el: New variable c-bitfield-key. * cc-mode.el: New variable c-bitfield-key. Wed Dec 09 1998 Martin Stjernholm * cc-engine.el (c-inside-bracelist-p): Tighter test for Java anonymous array expressions (i.e. "new Foo[] {.. bracelist ..}"). Sun Dec 6 1998 Martin Stjernholm * Release 5.25 Mon Nov 18 1998 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed some bugs with comments with tricky contents in obscure places inside bracelists. Cases 5A.3 and 9C-D changed. Mon Nov 11 1998 Martin Stjernholm * cc-engine.el (c-inside-bracelist-p): Don't trip up on C++ "operator[]". Mon Oct 31 1998 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Fixed bug where point would end up further down afterwards. Recognize '@' as a prefix operator for Pike. Mon Oct 24 1998 Barry A. Warsaw * cc-defs.el (c-major-mode-is): New defsubst to encapsulate major-mode checking. * cc-cmds.el, cc-engine.el, cc-lang.el: All major-mode checking is now spelled (c-major-mode-is 'mode) Mon Oct 23 1998 Barry A. Warsaw * cc-cmds.el (c-comment-indent): CASE 3: the looking-at should match against c-comment-start-regexp instead of comment-start. * cc-engine.el (c-inside-bracelist-p): Further dekludgification. When in C++ mode and searching to see if we're in a template definition, don't get tripped up by #include syntax! * cc-mode.el (c-submit-bug-report): Add comment-column to list of variables reported. Mon Oct 20 1998 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1): Do not trip on whitespace when skipping backwards over characters that can start a statement.

Warsaw * cc-langs.el (c-common-init): Make adaptive-fill-mode a buffer local variable and set it to nil. Mon Oct 15 1998 Barry A. Warsaw * cc-langs.el (c-common-init): Implement the new semantics for c-default-style. * cc-mode.texi: Document the new semantics for c-default-style. * cc-vars.el (c-default-style): Slightly different default semantics when the value is an alist, and there's a new special symbol in the choices: `other'. This is used when the major-mode is not specifically listed. Wed Oct 14 22:34:50 1998 Barry A. Warsaw * Release 5.24 Thu Oct 08 1998 Martin Stjernholm * cc-cmds.el (c-electric-brace): Added inexpr-class-open and inexpr-class-close handling. * cc-vars.el (c-hanging-braces-alist): Added inexpr-class-open and inexpr-class-close and changed the default setting for those two. Wed Oct 07 1998 Barry Warsaw * cc-cmds.el (c-electric-delete): Use function delete-forward-p if it exists. This is the blessed XEmacs 21 way of checking for this condition. Wed Sep 16 1998 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): CASE 15: Handle labels at beginning of blocks with hanging braces. Tue Sep 08 1998 Barry Warsaw * Bug reporting address is now bug-cc-mode@gnu.org Mon Aug 31 1998 Barry Warsaw * cc-defs.el (c-region-is-active-p): New function which encapsulates region activeness determination in both XEmacs and Emacs, regardless of whether region highlighting (e.g. zmacs-regions / transient-mark-mode) is turned on. * cc-langs.el (c-mode-menu): Use c-region-is-active-p so appropriate menu entries are active correctly across all X/Emacsen. * cc-vars.el Added definition of `other' widget type, which allows any value other than t or nil, but doesn't let the user type in any old thing. This is used in c-tab-always-indent as per Per's recommendation. Fri Aug 28 1998 Barry Warsaw * cc-langs.el (c-use-java-style): Removed as obsolete. (c-common-init): Implement the new semantics for c-default-style. Should be backwards compatible with old behavior, but allow for per-major-mode setting of the default style. * cc-mode.el (java-mode): No longer hard code the style setting to "java" style. This is now all handled by the new semantics for c-default-style. * cc-styles.el (c-initialize-builtin-style): No longer call c-set-style to set the default style. This is all handled by the new semantics for c-default-style. * cc-vars.el (c-default-style): This variable can now take either a string or an association list, mapping major mode symbols to style names. Update the docstring to describe the new interface, and elaborate the Custom widget to accept either type. Thu Aug 27 1998 Barry Warsaw * cc-styles.el (c-offsets-alist): The offset for a syntactic symbol can now also be a list, which is recursively evaluated using the previous semantics. The first non-nil value succeeds. (c-get-offset, c-evaluate-offset): Function to implement recursive evaluation for when a symbol's offset is a list (the first one to return a non-nil value succeeds -- should this be a stricter check for an integer return value?). Factored out of c-get-offset. (c-set-offset, c-read-offset): Error message indicates value could be a list. In former function, add listp check. * cc-vars.el (c-strict-syntax-p): Describe addition responsibilities. Mon Aug 24 1998 Martin Stjernholm * cc-engine.el (c-inside-bracelist-p, c-guess-basic-syntax): In Java brace lists may follow the new operator. Do not recognize them as in-expression statements. Case 7B changed in c-guess-basic-syntax. Sun Jun 07 1998 Martin Stjernholm * cc-engine.el (c-beginning-of-statement-1, c-guess-basic-syntax): Fixed indentation of try-catch-finally blocks nested inside if-statements. New case 13 in c-guess-basic-syntax; cases 13-16 renamed for this. New syntactic symbol catch-clause. * cc-styles.el New syntactic symbol catch-clause. Changed the default to not alter the indentation of multiline strings in any way. Sat Jun 06 1998 Martin Stjernholm * cc-langs.el Added recognition of IDL specific top-level keywords. Tue May 19 1998 Martin Stjernholm * cc-engine.el (c-search-uplist-for-classkey, c-looking-at-inexpr-block, c-guess-basic-syntax): Fixed bug in recognizing anonymous Java classes. Cleanups in the code that handles in-expression brace constructs. Sun May 03 1998 Martin Stjernholm * cc-engine.el (c-inside-bracelist-p): Rewrote the `=' detection loop to make it more clear and in some cases a lot faster.

Mon Apr 13 1998 Martin Stjernholm * cc-engine.el (c-add-class-syntax): New function that handles all inclass and related symbols in one place. The anchor position of inclass has changed in some situations. Sun Apr 12 1998 Martin Stjernholm * cc-cmds.el (c-beginning-of-statement): Handle blocks inside expressions. Wed Apr 08 1998 Barry Warsaw * cc-cmds.el (c-mark-function): Much better implementation which catches all the expected cases. (c-end-of-defun): When called programmatically with no arguments, arg is nil, so set it to 1. * cc-defs.el (c-point): Added 'eod. Mon Apr 06 1998 Martin Stjernholm * cc-engine.el (c-search-uplist-for-classkey, c-inside-bracelist-p, c-looking-at-inexpr-block, c-guess-basic-syntax): Support for Java anonymous classes. New case 6D in c-guess-basic-syntax. * cc-langs.el, cc-mode.el, cc-styles.el: Support for Java anonymous classes. New syntactic element inexpr-class.

They're handled as `inexpr-statement' now. Changed cases: 6, 10, 15A, 16E. New case 7B; old 7B-F renumbered. Fri Apr 03 1998 Barry Warsaw * cc-cmds.el (c-electric-brace): Removed brace-list-entry from the list of symbols that can be electrified because all cases where brace-list-entry was used should now be brace-entry-open's. Add new brace-entry-open to list of braces which can be electrified. * cc-engine.el (c-guess-basic-syntax): CASE 9C: brace-list-open => brace-entry-open. * cc-styles.el (c-style-alist): In "linux" and "python" styles, add brace-entry-open to mimic brace-list-open. Added description and entry for brace-entry-open, a new syntactic symbol. * cc-vars.el (c-hanging-braces-alist): Added brace-entry-open to mimic brace-list-open in default value. Updated docstring and defcustom spec to describe brace-entry-open and remove brace-list-entry. Thu Apr 02 1998 Martin Stjernholm * cc-align.el (c-lineup-inexpr-stat): New lineup function used in Pike mode. * cc-langs.el: New variables c-lambda-key and c-special-brace-lists for Pike. * cc-styles.el: New syntactic symbols inlambda, lambda-intro-cont, and inexpr-statement for Pike. * cc-engine.el: Support for the Pike language. Handle Pike-style brace lists ('({ })', '([ ])', '(< >)') and in-expression statements. New case 6 in c-guess-basic-syntax; CASES >= 6 ARE RENAMED because of this. New functions: c-looking-at-special-brace-list, c-looking-at-inexpr-stat, c-looking-at-inexpr-stat-backward. * cc-mode.el (pike-mode): New function; support for the Pike language. Tue Mar 31 1998 Martin Stjernholm * cc-cmds.el (c-comment-line-break-function): Insert newline when in a string literal. Fri Mar 27 1998 Barry Warsaw * cc-defs.el (c-forward-sexp, c-backward-sexp): Implementations of replacement defsubst to insulate ourselves from changes to forward-sexp and backward-sexp user level command. * cc-styles.el (c-read-offset): A better prompt which includes the syntactic symbol being changed. Wed Mar 18 1998 Barry Warsaw * cc-cmds.el (c-indent-line-or-region): New command. Remove `*' from interactive spec. * cc-langs.el (c-mode-menu): Change "Indent Line" to "Indent Line or Region". Mon Mar 16 19:13:24 1998 Barry A. Warsaw * Release 5.22 Thu Mar 12 1998 Barry Warsaw * cc-menus.el (cc-imenu-c++-generic-expression): Fix to handle explicitly specialized template classes. * cc-mode.texi: Added a paragraph on signal-error-on-buffer-boundary in the Limitations and Known Bugs section. Wed Mar 11 1998 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixed bug with member inits on the same line as the function header. Case 5D.1 changed. Wed Mar 11 1998 Barry Warsaw * cc-mode.el (c-submit-bug-report): Add signal-error-on-buffer-boundary to the list of variables that get reported. This is a losing XEmacs variable that breaks many things and should never be set by the user. Fri Mar 6 00:25:29 1998 Barry A. Warsaw * Release 5.21 Sat Feb 28 1998 Martin Stjernholm * cc-mode.el (c-initialize-on-load): Variable removed. Sat Feb 28 1998 Barry Warsaw * cc-engine.el (c-inside-bracelist-p): Fix for enum test. Fri Feb 27 1998 Martin Stjernholm * cc-mode.el (c-initialize-cc-mode): Moved require's to top level. Wed Feb 25 1998 Martin Stjernholm * cc-cmds.el (c-fill-paragraph): Always keep point in the same relative position. Fill comment before point if there's nothing else on the same line. Fill block comments after code a little better. Try harder to find a good fill-prefix when point is on a block comment ender line. Use c-Java-javadoc-paragraph-start in block comments in Java mode. Leave block comment ender alone when c-hanging-comment-ender-p is nil and point is on that line. Detect paragraph-separate in multiparagraph comments. Fix for bug that may strip the `*' off `*/' if fill-prefix ends with `*' and c-hanging-comment-ender-p is t. Added filling of multiline string literals. Always return t to disable filling in any unhandled area, i.e. actual code where fill-paragraph only mess things up. Tue Feb 24 1998 Martin Stjernholm * cc-engine.el (c-collect-line-comments): Require same comment start column. * cc-langs.el Added c-Java-javadoc-paragraph-start for use in c-fill-paragraph. Tue Feb 24 1998 Barry Warsaw * cc-cmds.el (c-fill-paragraph): Bind fill-paragraph-function to nil when calling fill-paragraph to avoid bogus recursion which will signal an error. Sat Feb 21 1998 Martin Stjernholm * cc-engine.el (c-guess-basic-syntax): Fixes for nesting of and repeated defun-open's inside extern and namespace clauses. This is done by passing a relpos to 'inextern-lang and 'innamespace. Also, the relpos in 'defun-open is no longer always bol. It's always bol when on the top level, however. Changed cases: 5A.5, 5I, 14A. Thu Feb 19 1998 Martin Stjernholm * cc-engine.el (c-forward-token-1, c-backward-token-1): New functions to move by tokens. (c-guess-basic-syntax): Fixes for Java 1.1 array initialization brace lists. Tue Feb 17 1998 Martin Stjernholm * cc-mode-19.el: Only define the functions if they aren't defined already. Tue Feb 10 1998 Martin Stjernholm * cc-make.el: Require cc-mode-19 if needed before batch compile, because it contains macro definitions that must be defined during compilation. Sun Feb 8 15:30:43 1998 Barry A. Warsaw * Release 5.20 Wed Feb 04 1998 Barry Warsaw * cc-mode.el (c-mode, c++-mode, objc-mode, java-mode): set imenu-case-fold-search to nil. Tue Feb 03 1998 Barry Warsaw * cc-langs.el (c-postprocess-file-styles): If a file style or file offsets are set, make the variables local to the buffer (via make-local-variable). * cc-styles.el (c-make-styles-buffer-local): Take an optional argument which switches between make-variable-buffer-local and make-local-variable. Generalize. Mon Feb 02 1998 Martin Stjernholm * cc-align.el (c-lineup-close-paren, c-indent-one-line-block): New indentation functions. * cc-cmds.el (c-beginning-of-statement, c-end-of-statement): Do not move by sentence in strings. Doc fixes. * cc-mode.texi: Document new indentation functions. Sat Jan 24 1998 Barry Warsaw * cc-defs.el (c-point): In XEmacs, use scan-lists + buffer-syntactic-context-depth to radically speed up locating top-level defun opening brace in some situations. When the braces hang, this can make c-parse-state from between 3 to 60 times faster. When they don't hang, this may be a few percentage points slower (not noticeable to me though). The variable c-enable-xemacs-performance-kludge-p toggles the behavior. This change has no effect on Emacs, which lacks the built-in function buffer-syntactic-context-depth. * cc-mode.texi: Discuss c-enable-xemacs-performance-kludge-p in the section on performance. * cc-vars.el (c-enable-xemacs-performance-kludge-p): New variable. Fri Jan 23 1998 Barry Warsaw * cc-cmds.el cc-defs.el cc-engine.el (c-beginning-of-defun, c-indent-defun, c-parse-state): Use (c-point 'bod) instead of beginning-of-defun directly. Tue Jan 20 1998 Martin Stjernholm * cc-cmds.el (c-beginning-of-statement): Speedup; it's only necessary to call `c-literal-limits' once when the function is entered. Mon Jan 19 1998 Barry Warsaw * cc-align.el (c-semi&comma-no-newlines-before-nonblanks, c-semi&comma-no-newlines-for-oneline-inliners): New functions, appropriate for c-hanging-semi&comma-criteria, but not placed on that variable by default. * cc-langs.el (c-mode-base-map): Comment out c-beginning-of-defun and c-end-of-defun bindings, since RMS doesn't want these to be the default. * cc-mode.texi: Describe c-beginning-of-defun and c-end-of-defun. Describe the new c-hanging-semi&comma-criteria functions. Sun Jan 18 1998 Martin Stjernholm * cc-cmds.el (c-beginning-of-statement): Handle multiple C++ line comments a little better. Almost completely rewritten. It's now more thorough when handling strings and comments and the transitions between them and the surrounding code. The statement parsing is also rewritten because `c-{beginning|end}-of-statement-1' does no longer do what we want in this function (e.g. c-b-o-s-1 doesn't go into blocks). It also works better for different counts and when sentence-flag is nil. * cc-engine.el (c-forward-syntactic-ws, c-backward-syntactic-ws): Removed the narrowings which doesn't seem to have much effect. Instead a simple check is made against the given limit. In `c-backward-syntactic-ws' this means that there's no need to search for bod, which helps up speed quite a lot in some areas. (c-collect-line-comments): New function that given the limits of one C++ style line comment returns the range for all adjacent line comments. This functionality is moved from the functions `c-literal-limits' and `c-literal-limits-fast'. (c-literal-limits): New function that finds the start and end pos of a comment or string surrounding point. This function is Emacs 19.34 compatible and it has a workaround for what seems to be a bug in `parse-partial-sexp' when we use an existing state to get the state for the very next character. (c-literal-limits-fast): A faster variant of `c-literal-limits' for newer Emacsen where the state returned from `parse-partial-sexp' contains the starting pos of the last literal. This does not contain the workaround described above. The function is not yet tested and therefore not in use for now. Note that these functions regard the position between the first and second char of a comment starter to be part of the comment. Although `parse-partial-sexp' (in Emacs 19 anyway) doesn't do this, it seems more intuitive to me. Maybe `c-in-literal' should do this too? Thu Jan 15 1998 Martin Stjernholm * cc-mode-19.el: Added `when' and `unless'. Thu Jan 15 1998 Barry Warsaw * cc-engine.el (c-guess-basic-syntax): Fixed a few byte compiler warnings. Wed Jan 14 1998 Barry Warsaw * cc-cmds.el (c-beginning-of-defun, c-end-of-defun): New commands which mimic the standard built-ins, but do a much better job of finding the open brace when it's hung on the right side (as is the case with the most common Java style). * cc-engine.el (c-backward-to-start-of-do): Break infloop for illegal code, e.g. when someone types while (TRUE) { at the top of a buffer, we shouldn't hang when the { is typed! Tue Jan 13 1998 Barry Warsaw * cc-cmds.el (c-beginning-of-statement): When moving forward by sentences, because we're either inside or at the start of a comment, be sure to limit movement to only within the extent of the comment. Sat Jan 10 1998 Barry Warsaw * cc-langs.el (c-java-method-key): I really don't remember why this was added, but it seems to do more harm than good. Besides, its value was clearly wrong, being inherited from Objective-C. * cc-mode.el (java-mode): Set c-method-key to nil. I don't think this is necessary for Java, and besides, the old value was inherited from Objective-C which was clearly not right. With this change, all regression tests pass and the example by Bengt Martensson also passes: class Baz { int blah() { return 1 + 2 + 3 + foobar() + 5 + 6; } } * cc-mode.texi Add some explanation to "gnu" style and "user" style, describing the relationship between these and user Customizations. * cc-vars.el (c-default-style): Change this back to "gnu" after (re-reading old) discussions with RMS. This may confuse users who set variables in the top-level of their .emacs files, or using the Custom interface, since those changes will get incorporated into the "user" style. RMS insists, however, that the default style be "gnu". Sun Jan 04 1998 Barry Warsaw * cc-cmds.el (c-electric-colon): Newlines should not be inserted before or after scope operators, regardless of the value of c-hanging-colons. * cc-engine.el (c-backward-to-start-of-if): Workaround a nasty to track down bug. If point is < lim, then this function can actually land you forward into the buffer. This can cause an infloop in c-beginning-of-statement-1. It is probably a bug that this function gets called with a lim > point, but that's even harder to figure out, so if that's the case when this function is called, it's simpler just to ignore lim and use bod. This breaks the infloop without causing broken indentation. Sat Jan 03 1998 Barry Warsaw * cc-align.el (c-lineup-dont-change): New lineup function that leaves the current line's indentation unchanged. Used for the new cpp-macro-cont syntactic symbol. * cc-cmds.el (c-electric-brace): namespace-open and namespace-close braces can hang. * cc-defs.el (c-emacs-features): Added autoload cookie which Steve Baur claims is necessary for XEmacs. * cc-engine.el (c-search-uplist-for-classkey): When searching up for a class key, instead of hardcoding the extended search for "extern", use the new variable c-extra-toplevel-key, which is language dependent. For C++, this variable includes the keyword "namespace" which will match C++ namespace introducing blocks. (c-guess-basic-syntax): Support for recognizing C++ namespace blocks, by elaborating on the mechanism used to find external language blocks. Searches which hardcoded "extern" now use c-extra-toplevel-key, a language dependent variable. Case clauses that were modified: CASE 5A.1, CASE 5A.4, CASE 5F, CASE 5I, CASE 14A. CASE 3: we can now determine whether we're at the beginning of a cpp macro definition, or inside the middle of one. Set syntax to 'cpp-macro in the former case, 'cpp-macro-cont in the latter. In both cases, the relpos is the beginning of the macro. (c-forward-syntactic-ws): Added code that skips forward over multi-line cpp macros. (c-beginning-of-macro): Moved, and made into a defsubst. This function can now actually find the beginning of a multi-line C preprocessor macro. (c-backward-syntactic-ws): Use c-beginning-of-macro to skip backwards over multi-line macro definitions. (c-in-literal, c-fast-in-literal): Use c-beginning-of-macro to find out whether we're in a multi-line macro definition. * cc-langs.el (c-C-extra-toplevel-key, c-C++-extra-toplevel-key, c-extra-toplevel-key): New variables which parameterize the search for additional top-level enclosing constructs. In all languages, extern lang blocks are supported (but maybe this should just be C and C++?). In C++, also namespace blocks are supported. * cc-menus.el Imenu patches by Masatake Yamato and Jan Dubois. * cc-mode.el (c++-mode): Set c-extra-toplevel-key to c-C++-extra-toplevel-key. (c-initialize-on-load): New variable, *not* customized. When set to t -- the default -- c-initialize-cc-mode is called when the cc-mode.el file is loaded, e.g. via (require 'cc-mode). This is backwards compatible with .emacs files that used CC Mode 4. I'm still not 100% sure this is the right thing to do. * cc-mode.texi: Added descriptions of the new C++ namespace syntactic symbols: namespace-open, namespace-close, innamespace. Added an example for this and also multi-line macros. Describe c-lineup-dont-change and the new cpp-macro-cont syntactic symbol. Remove the `known limitation' that multi-line macros aren't supported. * cc-styles.el (c-offsets-alist): Three new syntactic symbols: innamespace, namespace-open, namespace-close. These support C++ namespace blocks. Added new syntactic symbol cpp-macro-cont, by default bound to c-lineup-dont-change. This symbol is assigned to subsequent lines of a multi-line C preprocess macro definition. * cc-vars.el (c-default-style): Variable is user customizable so it's docstring should start with a `*'. Fri Jan 02 1998 Barry Warsaw * cc-engine.el (c-fast-in-literal): Function which should be faster than c-in-literal. This uses buffer-syntactic-context which is a speedy built-in that exists only in XEmacs. Make it's alias conditional on that built-in's existance. To be honest, the performance effects should be tested. Also c-fast-in-literal knows about multi-line cpp macros while c-in-literal does not. The latter should be taught about this, but this change will wait for a future mega-patch to handle multi-line macros. Thu Jan 01 1998 Barry Warsaw * cc-cmds.el (c-comment-line-break-function): When breaking a line-oriented comment, copy the comment leader from the previous line instead of hardcoding it to "// ". This ensures that whitespace between the slashes and the text is preserved. Tue Nov 18 1997 Barry Warsaw * cc-langs.el (c-mode-base-map): Bind c-mark-function using a portable representation of C-M-h that differentiates this from M-BS on both XEmacs and Emacs. Sat Nov 15 1997 Barry Warsaw * cc-cmds.el (c-electric-pound, c-electric-brace, c-electric-slash, c-electric-star, c-electric-semi&comma, c-electric-colon, c-electric-lt-gt, c-scope-operator, c-indent-command, c-indent-exp, c-indent-defun, c-backslash-region, c-fill-paragraph): Added "*" to interactive spec to barf-if-buffer-read-only. Fri Nov 14 1997 Barry Warsaw * cc-cmds.el (c-fill-paragraph): regexp-quote the fill-prefix when search forward for the end of line oriented comments. This is in case the fill-prefix contains regexp special characters (e.g. fill-prefix == " //* ") (c-backslash-region): Do not preserve the zmacs region (XEmacs). Wed Nov 12 1997 Barry Warsaw * cc-langs.el (c-mode-base-map): c-mark-function moved back to M-C-h. RMS says: "It ought to be on M-C-h, because that is the key to mark one function definition in whatever language you're using." I don't remember why it was moved in the first place. Tue Nov 04 1997 Barry Warsaw * cc-cmds.el (c-electric-backspace, c-electric-delete): Interactive spec should have a read-only *. Thu Oct 30 1997 Barry Warsaw * cc-styles.el (c-styles-alist): Merged "jdk" into "java" style and removed "jdk" style. Only differences now are inline-open and c-basic-offset. Wed Oct 29 1997 Barry Warsaw * cc-mode.texi Document "jdk" style. * cc-styles.el (c-style-alist): "jdk" style given by Martin Buchholz for conformance with Sun's JDK style. Fri Oct 10 1997 Barry Warsaw * cc-styles.el (c-set-style-2, c-initialize-builtin-style): Don't special case "cc-mode", it's a derived style. Fix setup of derived style "cc-mode". Introduce the new default style "user" which contains all user customizations. The style "cc-mode" is retained as an alias, but it's use is deprecated. The default style variable has been renamed c-default-style. * cc-vars.el (c-site-default-style): Renamed to c-default-style. Also, the default value is now "user". Mon Oct 6 19:12:51 1997 Barry A. Warsaw * Release 5.19 Mon Oct 6 19:09:17 1997 Barry A. Warsaw * cc-engine.el (c-guess-basic-syntax): CASE 5F: extern-lang-close relpos should be element 0 of inclass-p, not element 1. * cc-cmds.el (c-progress-init, c-progress-fini): Be slient if c-progress-interval is nil. * cc-vars.el (c-progress-interval): Document new semantics Fri Oct 3 23:10:04 1997 Barry A. Warsaw * cc-engine.el (c-beginning-of-statement-1): Watch out for keywords which have a preceding underscore. Fri Sep 26 23:30:58 1997 Barry A. Warsaw * cc-menus.el: Patches to Imenu support given by "Masatake (jet) YAMATO" . (Jan Dubois) jan.dubois@ibm.net * cc-cmds.el (c-comment-line-break-function): Fix for when comment starts at comment-column and there is non-whitespace preceding this on the current line. * cc-mode.el (c-submit-bug-report): Remove c-recognize-knr-p. Add c-comment-continuation-stars. Mon Sep 22 15:47:02 1997 Barry A. Warsaw * cc-styles.el (c-initialize-builtin-style): Only use copy-tree if it is funcall-able. This is the right patch, and was given by Erik Naggum Tue Sep 16 19:23:24 1997 Barry A. Warsaw * Release 5.18 Tue Sep 16 23:17:15 1997 Barry A. Warsaw * cc-menus.el (cc-imenu-c-prototype-macro-regexp): New variable. (cc-imenu-c++-generic-expression): Patches to better match C++ code. Given by jan.dubois@ibm.net (Jan Dubois) * cc-menus.el (cc-imenu-java-generic-expression): Removed test for declaration statements. Patch given by Ake Stenhoff , as forwarded to me by RMS. * cc-menus.el: Imenu support for Objective-C given by Masatake (jet) YAMATO. * cc-mode.el (objc-mode): Bind imenu-create-index-function to cc-imenu-objc-function to enable Imenu support for Objective-C. Contributed by Masatake (jet) YAMATO. Mon Sep 15 23:21:51 1997 Barry A. Warsaw * cc-styles.el (c-initialize-builtin-style): Use existing copy-tree if it's defined. copy-sequence doesn't work; the c-offsets-alist must be copied recursively. Use copy-tree solution given by Simon Marshall. Fri Sep 5 04:47:03 1997 Barry A. Warsaw * cc-cmds.el (c-beginning-of-statement): Fixes in sentence movement to properly handle M-e moving forward into a comment when looking at preceding whitespace, and M-a moving backward into comment when looking at following whitespace. Uncommented the looking-at call in the sentence-flag clause so that moving by forward-sentence when looking at the beginning of a comment works again. A previous log message in cc-mode.el indicates this was commented out "because c-beginning-of-statement-1 should do the right thing", but clearly it doesn't. I don't know if this breaks something else, because I can't figure out why it was commented out in the first place. * cc-langs.el: Define `/' in c-mode-base-map since all modes now support c-electric-slash. Define C-c C-e in mode-specific maps instead of c-mode-base-map since c-expand-macro is meaningless in Java and IDL. * cc-engine.el (c-end-of-statement-1): Wrap backward-up-list in a c-safe call so no error results when buffer contains only a comment and point is at eob. Fri Sep 5 00:50:41 1997 Barry A. Warsaw * Release 5.17 Fri Sep 5 04:47:03 1997 Barry A. Warsaw * cc-cmds.el (c-beginning-of-statement): Fixes in sentence movement to properly handle M-e moving forward into a comment when looking at preceding whitespace, and M-a moving backward into comment when looking at following whitespace. * cc-langs.el: Define `/' in c-mode-base-map since all modes now support c-electric-slash. Define C-c C-e in mode-specific maps instead of c-mode-base-map since c-expand-macro is meaningless in Java and IDL. * cc-engine.el (c-end-of-statement-1): Wrap backward-up-list in a c-safe call so no error results when buffer contains only a comment and point is at eob. * cc-cmds.el (c-beginning-of-statement): Uncommented the looking-at call in the sentence-flag clause so that moving by forward-sentence when looking at the beginning of a comment works again. A previous log message in cc-mode.el indicates this was commented out "because c-beginning-of-statement-1 should do the right thing", but clearly it doesn't. I don't know if this breaks something else, because I can't figure out why it was commented out in the first place. Tue Aug 26 22:31:55 1997 Barry A. Warsaw * cc-styles.el (c-style-alist): "python" style, knr-argdecl-intro == + Mon Aug 25 17:25:12 1997 Barry A. Warsaw * cc-engine.el (c-inside-bracelist-p): Add a test to the enum list test so that the following code won't erroneously recognize as inside a brace list: static PyObject ** unpack_sequence(v, argcnt, why) PyObject **v; int argcnt; enum *why_code; { int i; Otherwise, the `enum' in the K&R decl trips this code up. * cc-styles.el (c-style-alist): "python" style, fill-column = 78 Fri Aug 22 20:25:57 1997 Barry A. Warsaw * cc-cmds.el (c-comment-line-break-function): Don't break line in the middle of a string. Mon Aug 18 17:37:24 1997 Barry A.

Warsaw * cc-styles.el (c-style-alist): "python" style requires c-comment-continuation-stars to be "". Fri Aug 15 17:26:05 1997 Barry A. Warsaw * Release 5.16 Fri Aug 15 18:39:10 1997 Barry A. Warsaw * cc-styles.el (c-style-alist): "python" style requires c-comment-continuation-stars to be "". * cc-engine.el (c-end-of-statement-1): Eliminate false hits on important characters inside literals (strings, comments). Tue Aug 12 21:47:18 1997 Barry A. Warsaw * cc-cmds.el (c-comment-line-break-function): In this function, and the defadvice, call indent-new-comment-line if not in a comment. * cc-vars.el (c-buffer-is-cc-mode): Definition moved to cc-mode.el * cc-mode.el (c-buffer-is-cc-mode): Definition moved here from cc-vars.el. Also, put permanent-local property on variable so it's value won't get killed by kill-all-local-variables. This makes it easier for non-CC Mode derived modes to be initialized correctly. * cc-cmds.el (c-electric-brace): In preserve-p test, don't test char-before when at bobp. Open brace at bobp is illegal in most modes, but not awk-mode, which depends on CC Mode. Mon Aug 11 15:37:04 1997 Barry A. Warsaw * cc-mode.el (c++-mode, java-mode, objc-mode, idl-mode): Remove obsolete variable c-double-slash-is-comments-p. * cc-langs.el (c-double-slash-is-comments-p): Remove obsolete variable. * cc-cmds.el (c-fill-paragraph): Remove conditional on obsolete variable c-double-slash-is-comments-p. * cc-styles.el (c-style-alist): Conform comment settings to RMS's preferences. Thu Aug 7 19:21:32 1997 Barry A. Warsaw * cc-styles.el (c-set-offset): Added autoload cookie. Thu Aug 7 18:13:12 1997 Barry A. Warsaw * Release 5.15 Thu Aug 7 19:21:32 1997 Barry A. Warsaw * cc-styles.el (c-set-offset): Added autoload cookie. * cc-langs.el (c++-mode-syntax-table, java-mode-syntax-table, objc-mode-syntax-table, idl-mode-syntax-table): Added autoload cookies. c-mode-syntax-table already has one. Wed Aug 6 21:50:08 1997 Barry A. Warsaw * cc-mode.el (c-initialize-cc-mode): Check all cc-mode-19 interface requirements. Tue Aug 5 21:56:02 1997 Barry A. Warsaw * cc-align.el (c-lineup-java-throws): Change the `when' clause to an `if-progn' :-( * cc-langs.el (c-common-init): Make comment-line-break-function buffer local iff it's boundp. * cc-cmds.el: defadvice for indent-new-comment-line keys off of c-buffer-is-cc-mode instead of an explicit major-mode list. this means non-CC Mode derived modes will work properly * cc-mode.el (c-initialize-cc-mode): Set c-buffer-is-cc-mode to t. * cc-vars.el (c-buffer-is-cc-mode): New variable * cc-mode.texi: In FAQ section, document use of c-mode-base-map instead of c-mode-map. * cc-mode.el (c-initialize-cc-mode): Give in to the pressure. require 'cc-mode-19 if functionp is not bound. Too many novice errors without this. * cc-cmds.el: Added advice for indent-new-comment-line so older Emacsen work if they don't have the variable comment-line-break-function. Mon Aug 4 14:55:40 1997 Barry A. Warsaw * cc-langs.el (c-mode-base-map, c++-mode-map): Move `/' as an electric character from c++-mode-map to c-mode-base-map for all languages. * cc-cmds.el (c-electric-slash): Make this work as the final slash in a */ block oriented comment closing token. * cc-vars.el (c-comment-continuation-stars): Can take a nil value.

(c-comment-start-regexp): Initialize from c-C++-comment-start-regexp. (c-populate-syntax-table, c-setup-dual-comments): Merge both functions into c-populate-syntax-table. With the new 9X draft C standard, both line and block oriented comments are supported in all modes, so always set up the syntax tables to support both comment styles. (c-mode-syntax-table, c++-mode-syntax-table, java-mode-syntax-table, objc-mode-syntax-table, idl-mode-syntax-table): Use the new syntax table initialization idioms. (c-enable-//-in-c-mode): Obsolete. * cc-mode.el (c-mode): c-comment-start-regexp uses c-C++-comment-start-regexp to support line oriented comments. Wed Jul 30 00:01:45 1997 Barry A. Warsaw * cc-engine.el (c-guess-basic-syntax): CASE 5D.4: template argument continuation lines are now analyzed as template-args-cont. * cc-styles.el (c-offsets-alist): Added template-args-cont syntactic symbol * cc-mode.texi: Added description of template-args-cont syntactic symbol Sat Jul 26 16:03:33 1997 Barry A.

Warsaw * Release 5.14 Sat Jul 26 16:03:33 1997 Barry A. Warsaw * cc-styles.el (c-styles-alist): In "java" style, set c-hanging-comment-starter-p to nil to preserve Javadoc starter lines. Fri Jul 25 22:17:07 1997 Barry A. Warsaw * cc-engine.el (c-beginning-of-statement-1): When checking for bare semi, don't match on a semi following a close brace, otherwise the following legal code fails: void foo() { static struct Pattern nums = {1, 2, 3}; int j = 2; } This might break some bare semi idioms but those are probably more rare than static initializers. * cc-mode.texi: Describe support for idl-mode * cc-vars.el (idl-mode-hook): New variable. * cc-mode.el (idl-mode): Support for CORBA's IDL language. * idl-font-lock.el: Unsupported font-lock definitions for IDL. This should be merged in with font-lock.el * cc-mode.el (c-initialize-cc-mode): move the calling of c-make-styles-buffer-local into c-initialize-builtin-style. * cc-styles.el (c-set-style-2): Fixed broken implementation of inherited styles. * cc-mode.texi: Document c-initialization-hook.

Thu Jul 17 03:36:22 1997 Barry A. Warsaw * cc-langs.el (c-symbol-key): first character must be a letter or underscore Wed Jul 16 23:56:58 1997 Barry A. Warsaw * Release 5.13. Thu Jul 17 03:36:22 1997 Barry A. Warsaw * cc-langs.el (c-symbol-key): first character must be a letter or underscore * cc-defs.el (c-load-all): Function deleted. * cc-mode.el (c-initialize-cc-mode): New function.

Warsaw * cc-styles.el (c-initialize-builtin-style): use copy-sequence instead of copy-tree so the cl module isn't necessary. * cc-cmds.el (c-electric-brace): fix ebola eradication consequence in the preserve-p test. Tue Jul 8 23:47:47 1997 Barry A. Warsaw * Release 5.12 Mon Jul 7 23:47:02 1997 Barry A. Warsaw * cc-styles.el, cc-mode.el, cc-menus.el, cc-langs.el, cc-engine.el, cc-compat.el, cc-cmds.el, cc-align.el: Reorganization to support byte-recompile-directory. * Release: Don't put release number in tar file Thu Jul 3 22:54:03 1997 Barry A. Warsaw * cc-langs.el (c-mode-base-map): Proper binding of c-electric-backspace and c-electric-delete, based on the policy of the various maintainers. Thank goodness for delete-key-deletes-forward! * cc-vars.el (c-tab-always-indent, c-hanging-braces-alist): Minor changes to the cutomize format. * cc-mode.texi: Fixed spelling of Texinfo * cc-mode-19.el: Initial revision * cc-menus.el, cc-engine.el, cc-compat.el, cc-cmds.el, cc-align.el: Major Ebola eradication. Wed Jul 2 21:33:04 1997 Barry A. Warsaw * cc-engine.el (c-crosses-statement-barrier-p, c-guess-basic-syntax): Ebola eradication. * cc-cmds.el (c-indent-region): Call c-echo-parsing-error to echo last parsing error that may have occurred. * cc-engine.el (c-echo-parsing-error): New function. * cc-engine.el (c-parsing-error): new variable (c-parse-state): When an unbalanced close brace is discovered, don't raise an error (prevents insertion of character). Insert the character, display a warning message, and set c-parsing-error so syntax echoing will be disabled. (c-show-syntactic-information, c-indent-line): Suppress syntax echoing if c-parsing-error is non-nil. * cc-styles.el: Added require of cl to pick up definition of copy-tree. Mon Jun 30 21:41:00 1997 Barry A. Warsaw * cc-langs.el, cc-mode.el (c-mode-map, c++-mode-map, objc-mode-map, java-mode-map): Moved defvars from cc-langs.el to cc-mode.el for use in c-mode, c++-mode, objc-mode, and java-mode docstrings. Actual population of these mode maps remains in cc-langs.el. * cc-mode.el: Require cc-langs at top level, so as to get the definitions for c-mode-map, et al. that are used in the *-mode docstrings. Fri Jun 27 17:33:32 1997 Barry A. Warsaw * cc-langs.el (c-mode-syntax-table): Added autoload cookie for gdb-mode. Thu Jun 26 21:12:56 1997 Barry A. Warsaw * cc-engine.el (c-guess-basic-syntax): CASE 5H: Whack one ebola infection (e.g. using memq with the results of following-char in XEmacs 20). * cc-styles.el: Added two require's that make autoload call of (c-set-style) work. Sun Jun 22 16:40:30 1997 Barry A. Warsaw * cc-cmds.el (c-electric-delete): Don't call c-electric-backspace interactively. Fri Jun 20 20:40:33 1997 Barry A. Warsaw * cc-mode.el (c-mode, c++-mode, objc-mode, java-mode): Make sure to call c-update-modeline after the hooks are run, so that the modeline accurately reflects auto-newline and delete-key minor modes if the hooks set c-hungry-delete-key or c-auto-newline directly. * cc-align.el (c-lineup-java-throws): Fixed some regressions. Fri Jun 20 19:55:55 1997 Barry A. Warsaw * Public Release 5.11 * cc-mode.texi: Describe changes to support separation of Backspace and Delete in XEmacs 20. * cc-vars.el (c-delete-function): renamed to c-backspace-function. (c-backspace-function): New variable. * cc-cmds.el (c-electric-backspace, c-electric-delete): Old X/Emacs 19 behavior typically bound to the backspace keysym is renamed to c-electric-backspace (which consults c-backspace-function). c-electric-delete (c-delete-function) is now bound to the delete keysym, which in XEmacs 20 is separated. * cc-langs.el (c-mode-base-map): No longer bind "\177" as a way to spell [delete] and [backspace]. Bind these two keys separate to support XEmacs 20's separation of forward deletion and backward deleteion. This means that in Emacs 19 and XEmacs 19, the backspace keysym is now bound to c-electric-backspace, but the functionality is the same (although the variable this consults is now called c-backspace-function). * cc-engine.el (c-show-syntactic-information): Minor optimization. Tue Jun 17 03:21:50 1997 Barry A. Warsaw * cc-align.el (c-lineup-multi-inher): Fixed small order dependency * cc-align.el (c-langelem-col): New defsubst. Convert all appropriate calls calculating the column of the langelem's relpos to use this function. * cc-align.el (c-lineup-java-throws): New function * cc-styles.el (c-style-alist): "java" style's func-decl-cont is associated with c-lineup-java-throws so long throws lines line up exceptions. * cc-styles.el (c-offsets-alist): Substituted RMS's description of func-decl-cont, with a minor change. * cc-mode.texi: Substituted RMS's description of func-decl-cont, with a minor change. Thu Jun 12 13:57:35 1997 Barry A. Warsaw * cc-styles.el (c-styles-alist): Changed topmost-intro-cont offset to + in Java style. This is closer to what people expect for default instance variable initializations. Wed Jun 11 18:20:59 1997 Barry A. Warsaw * cc-mode.texi: LFD => C-j RMS> I've decided to mostly stop using LFD as the name of an input RMS> character because PCs do not have a linefeed key. So please RMS> change the cc-mode manual to use @kbd{C-j} rather than @key{LFD}. Mon Jun 9 15:20:10 1997 Barry A. Warsaw * cc-styles.el (c-offsets-alist): A few minor changes to the docstring. Mon Jun 2 23:37:51 1997 Barry A. Warsaw * Beta Release 5.09 Sun Jun 1 16:23:11 1997 Barry A. Warsaw * cc-mode.el (c-load-all): cc-menus depends on cc-langs. * cc-langs.el (c-mode-base-map): New variable. All maps, including c-mode-map inherit from this map. This makes menu creation more straightforward for Emacs, although it is unnecessary for XEmacs. (c-make-inherited-keymap): Use c-mode-base-map as the parent map. Sat May 31 17:35:55 1997 Barry A. Warsaw * cc-langs.el (c-common-init): Conversion to the easymenu library for creation of popup and menubar menus. * cc-menus.el: Conversion to the easymenu library for creation of popup and menubar menus. * cc-mode.el (c-emacs-features): Make this work for Emacsen after 19.34. Fri May 30 15:38:09 1997 Barry A. Warsaw * cc-mode.el (c-emacs-features): Change the XEmacs 19 test from vectorp to arrayp, since we're using aref to access an element. Use this test also for Emacs 19, with a few key differences: the element returned in Emacs 19 is a cons cell. Also, arrayp doesn't return t for char-tables in Emacs 19.34, but will in Emacs 19.35. Tue May 27 21:23:51 1997 Barry A. Warsaw * cc-engine.el (c-guess-basic-syntax): CASE 5C.3: changing looking-at regexp to throws[ \t\n] CASE 15E: if we're in Java and looking at the throws clause that follows a method's parameter list, we need to go back to the beginning of the statement to find the start of the method. Fri May 23 14:58:30 1997 Barry A. Warsaw * Beta Release 5.07 * cc-vars.el: Added a require of the custom library, for Emacs 19.34 compatibility. Thu May 22 22:53:25 1997 Barry A. Warsaw * cc-mode.texi: Document the new default for c-style-variables-are-local-p. This variable is now nil by default. * cc-styles.el (c-make-styles-buffer-local): New function. By default all style variables are now global in value. Call this function to make them buffer local. This function is called automatically at load time if c-style-variables-are-local-p is non-nil. * cc-vars.el (c-style-variables-are-local-p): Default value is now nil. Tue May 20 23:59:19 1997 Barry A. Warsaw * cc-menus.el (c-popup-menu): Obsolete. (c-mode-menu): Optional argument to add " Mode Commands" to the title, in XEmacs only. * cc-langs.el (c-common-init): Get rid of the pre-XEmacs-19.10 way of doing popup menus. Make sure that in XEmacs, the menubar title is just the modename, but the popup has "MODENAME Mode Commands". Tue May 13 22:57:24 1997 Barry A. Warsaw * cc-align.el (c-lineup-C-comments): Fixes to handle all situations where the first line of a block comment has more stars on it than subsequent lines. This not only picks up the Javadoc style, but also /********************************************************************* * Routines formerly in objectPalette.c *********************************************************************/ * cc-engine.el (c-guess-basic-syntax): CASE 6A: Removed tests for ObjC & Java method closing parens since none of the test cases touched this code, and it broke close-paren on a separate line being recognized as arglist-close. * cc-langs.el: Removed most byte-compiler warnings by removing many obsolete variables. Fri May 9 21:54:27 1997 Barry A. Warsaw * cc-cmds.el (c-fill-paragraph): Included franl@world.std.com (Francis Litterio) patch that makes c-fill-paragraph preserve fill-prefix. * cc-engine.el (c-guess-basic-syntax): CASE 6C: when checking for a `for' statement, watch out for underscore separated symbols: for_each Tue May 6 23:18:13 1997 Barry A. Warsaw * Restructuring completed for version 5.xx Tue May 6 19:16:48 1997 Barry A. Warsaw * cc-mode.el (c-style-alist, c-set-style-1): Added support for inherited styles. * Restructuring began for version 5.00 Sat Mar 29 20:01:42 1997 Barry A. Warsaw * Public Release 4.389. Fri Mar 28 16:48:31 1997 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5C: watch out for Java abstract method definitions. These are distinguished from normal throws clauses since they cross statement boundaries. Tue Mar 25 03:19:17 1997 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5A.3: use boi instead of bol. Thu Mar 20 16:46:13 1997 Barry A. Warsaw * cc-mode.el (c-Java-comment-start-regexp): Recognize the three Java styles of comments: 1) traditional C block; 2) javadoc style /** ...; 3) C++ style. (java-mode): Set buffer local variable c-comment-start-regexp to c-Java-comment-start-regexp. (c-fill-paragraph): Use c-comment-start-regexp derived regular expression when checking for c-hanging-comment-starter-p, so javadoc styles are handled correctly in Java mode. * cc-mode.el (c-lineup-C-comments): Change the re-search-forward to a looking-at in the innermost test. This catches these styles of comments: /* Test for garbage collection. If the pool's free size is greater thaasds asdf asdf asdf asdf asdf asd fas fa asdf asf asdf asdf adf asdf asdf asdf asdf asdf glob chob stillp nasty toes winko stagilly frankly sut sut hoey */ =!= * cc-mode.el (c-add-syntax): Move macro definition to before it's first use. * cc-mode.el (c-submit-bug-report): capture buffer local variable values which are printed in the post-hook, while the current buffer is the CC Mode buffer we're interested in. reporter-submit-bug-report leaves the current buffer as the mail buffer, so buffer local variables will not get the proper value. Tue Mar 18 16:43:13 1997 Barry A. Warsaw * cc-mode.el (c-inher-key): Require the regexp group that contains the `:'. Previously it was optional, but that broke other code. Sun Mar 16 16:17:57 1997 Barry A. Warsaw * cc-mode.el (c-fill-paragraph): Do not set fill-prefix to "*" when looking-at "*/", otherwise the following example does not fill properly (the last start gets deleted). /* this is a comment */ Mon Mar 10 16:25:49 1997 Barry A. Warsaw * cc-mode.el (c-lineup-C-comments): Handle more cases, especially when comment lines aren't prefixed with stars. Sun Mar 9 20:09:16 1997 Barry A. Warsaw * Public Release 4.379. Mon Mar 10 01:04:38 1997 Barry A. Warsaw * cc-mode.el (c-lineup-C-comments): Handle more cases, especially when comment lines aren't prefixed with stars. Sat Mar 8 00:36:55 1997 Barry A. Warsaw * cc-mode.el (c-Java-class-key): optional space after protection key should be inside first paren group. Fri Feb 28 18:12:02 1997 Barry A. Warsaw * cc-mode.el (c-functionp, c-copy-tree): Better compatibility checks between XEmacs and Emacs. (c-mapcar-defun): Obsolete. Mon Feb 24 22:49:43 1997 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5B.1: watch out for throw() clauses which could follow a member init list in a constructor. Thu Feb 20 19:32:20 1997 Barry A. Warsaw * cc-mode.el (c-submit-bug-report): Display c-indentation-style, but not in the setq. * cc-mode.el (c-Java-special-key): New variable recognizes Java "implements", "extends", and "throws" keywords. (c-guess-basic-syntax): CASE 5C: recognize Java constructs "implements", "extends", and "throws"; CASE 5C.3: differentiate between "throws" == func-decl-cont, and "implements" or "extends" == inher-intro or inher-cont; CASE 5D.3: removed; CASE 5D.4 => 5D.3; CASE 5D.5 => CASE 5D.4; CASE 5D.6 => CASE 5D.5; CASE 5K: don't need to look for Java keywords. (c-lineup-java-inher): Better indentation calculation for Java inheritance constructs. Wed Feb 19 23:29:00 1997 Barry A. Warsaw * Beta Release 4.372. Thu Feb 20 04:07:11 1997 Barry A. Warsaw * cc-mode.el (c-Java-special-key, c-guess-basic-syntax, c-lineup-java-inher): Recognize Java "extends", "implements", and "throws" clauses and map them into 'inher-intro, 'inher-cont, and 'func-decl-cont syntactic symbols. Do the indentation as of Java inheritance lines better. Tue Feb 18 03:31:57 1997 Barry A. Warsaw * cc-mode.texi: Change documentation to reflect syntactic symbol change from 'ansi-funcdecl-cont to 'func-decl-cont. * cc-mode.el (c-offsets-alist): Changed the syntactic symbol 'ansi-funcdecl-cont to 'func-decl-cont. This symbol is useful in Java throws declarations. (c-lineup-java-inher): New function for lining up "implements" continuations (i.e. inheritance in Java). (c-style-alist): In "java" style, set 'inher-cont to c-lineup-java-inher. (c-Java-class-key): Optional c-protection-key can appear before the "class" keyword. Thu Feb 13 21:39:38 1997 Barry A. Warsaw * cc-mode.el (c-beginning-of-statement-1): First, check for bare semi-colon, which is a legal statement but not caught by the more intense loop later on. * cc-mode.el (c-style-alist): Fixes to "ellemtel" style given by Colin Rafferty . * cc-mode.el (c-beginning-of-statement): Don't use forward-sentence when looking at a C block comment start. c-beginning-of-statement-1 will do the right thing. Sun Feb 9 07:28:42 1997 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5C: watch for scope operators * cc-mode.el (c-lineup-C-comments): Watch out for no leading stars. Thu Feb 6 19:07:09 1997 Barry A. Warsaw * cc-mode.texi: Document that c-set-style is bound to `C-c .' * cc-mode.el (c-set-style): Add initial contents (the value of c-indentation-style), and history on the style name. (c-mode-map): Bind c-set-style on `C-c .' * cc-mode.el (c-read-offset, c-read-offset-history): Use completing-read, with REQUIRE-MATCH nil, so that offsets can be completed when they are function names. Also implement read history. * cc-mode.el (c-guess-basic-syntax): CASE 15D: fix infinite loop problem in while... clause looking for statement starting at boi, when using run-in statement styles. * cc-mode.el (cc-imenu-java-generic-expression): New variable for integration of java-mode with imenu. (java-mode): Use cc-imenu-java-generic-expression. * cc-mode.texi: Describe the use of c-hanging-comment-starter-p and c-hanging-comment-ender-p, as well as the fill-paragraph command. In the known bugs section, do not recommend using filladapt. Wed Feb 5 23:50:52 1997 Barry A. Warsaw * cc-mode.el (c-hanging-comment-starter-p): New variable, analogous to c-hanging-comment-ender-p. (c-fill-paragraph): Use c-hanging-comment-starter-p. Mon Feb 3 16:36:03 1997 Barry A. Warsaw * cc-mode.texi: Added a note about c-Java-defun-prompt-regexp in the section on performance. * cc-mode.el (java-mode): Do not set defun-prompt-regexp to c-Java-defun-prompt-regexp. In the following example, putting point on he brace that opens main() and hitting M-C-a will send both Emacs 19.34 and XEmacs 19.15 into tight CPU loops. -------------------- snip snip -------------------- import java.io.*; import java.lang.*; class foo { public static void main(String[] args) throws java.io.IOException, java.io.FileNotFoundException { FileInputStream bs = new FileInputStream("j.dat"); System.out.println(bs.readLine()); } } Sun Feb 2 18:11:17 1997 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 2: relpos for 'c and 'c++ is now boi. Mon Jan 27 18:55:02 1997 Barry A. Warsaw * Public Release 4.353 Mon Jan 27 16:25:57 1997 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 15D: do not assume that boi of previous statement is the beginning of a statement. Wed Jan 22 23:42:59 1997 Barry A. Warsaw * cc-mode.el: Removed the require of imenu. This currently breaks in XEmacs if you have imenu around (which hasn't been completely ported yet), and I think it's no longer necessary for Emacs. Tue Jan 21 20:47:23 1997 Barry A. Warsaw * cc-mode.el (c-cleanup-list, c-electric-brace): New clean-up option: brace-elseif-brace. * cc-mode.el (c-style-variables-are-local-p): New variable which controls whether indentation style variable are buffer local are not. By default, for backwards compatibility, this variable is t. Tue Jan 7 23:53:43 1997 Barry A. Warsaw * cc-mode.el (c-Java-access-key): set to nil since Java doesn't have C++-like access labels. Mon Jan 6 23:03:21 1997 Barry A. Warsaw * cc-mode.texi: Document new built-in styles. * cc-mode.el (c-style-alist): Added "python" style. Thu Jan 2 21:13:52 1997 Barry A.

Warsaw * cc-mode.el (c-lineup-C-comments): A much better implementation that handles all common star-prefixed block comment styles (see below). (c-block-comments-indent-p): obsolete and removed. int main() { /* * */ /* ** ** */ /** ** ** **/ /*** *** *** *** ***/ /** *** *** **/ } * cc-mode.el (c-indentation-style): take default value from c-site-default-style. Mon Dec 23 23:48:26 1996 Barry A. Warsaw * cc-mode.el (adaptive-fill-regexp): For all but XEmacs 19.13, the default should be nil. Thu Dec 19 21:10:35 1996 Barry A. Warsaw * cc-mode.el (c-emacs-features): detect Infodock. (c-common-init, c-mode-map): Don't install menus for Infodock. * cc-mode.el (c-indent-exp): fixed infinite loop when multi-line C comment is last thing in buffer. (c-guess-basic-offset): fixed error when K&R C-like macro is first non-syntactic whitespace in file. * cc-mode.el (c-C++-comment-start-regexp): use a more efficient representation. Tue Dec 10 20:32:21 1996 Barry A. Warsaw * cc-mode.el (c-buffer-style): New variable. Fri Oct 4 19:10:15 1996 Barry A. Warsaw * Public Release 4.322 Fri Oct 4 20:28:14 1996 Barry A. Warsaw * cc-mode.el (c-backslash-region): If a line ends at the end of the region, always delete backslash from it. Given by Richard Stallman 1996-08-31 (c-backslash-region): In XEmacs, keep region active. * cc-mode.el (c-mode-map): Install FSF mode menu into menubar using the name "CC-Mode" for all supported modes. (c++-mode-map, objc-mode-map, java-mode-map): Don't install an additional FSF menu. * cc-mode.el: Removed the following variables from the built-in "cc-mode" style: c-echo-syntactic-information-p c-string-syntax-p c-tab-always-indent c-inhibit-startup-warnings-p These control how the mode acts, not how code looks. Mon Sep 30 22:24:48 1996 Barry A. Warsaw * cc-mode.el (c-indent-command): Sync docstring with texinfo documentation, and actual behavior. Thu Sep 19 18:13:13 1996 Barry A. Warsaw * cc-mode.el (c-style-alist): Added "linux" style. Tue Aug 20 21:08:13 1996 Barry A. Warsaw * cc-mode.el (c-lineup-comment): preserve comment-column. Mon Aug 19 22:24:41 1996 Barry A. Warsaw * cc-mode.el (c-gnu-impose-minimum): Don't impose minimum on comment-only lines. Tue Aug 6 21:11:39 1996 Barry A. Warsaw * cc-mode.el (c-mark-function): Moved to C-c C-m (c-show-syntactic-information): Optional universal argument inserts analysis as a comment on the line. Fri Jul 5 23:57:19 1996 Barry A. Warsaw * cc-mode.el (c-insert-tab-function): New variable allowing tab-to-tab-stop to be used instead of insert-tab. (c-indent-command): Use c-insert-tab-function variable. Fri Jun 7 14:31:47 1996 Barry A. Warsaw * cc-mode.el (java-mode): Use (c-set-style "java"); i.e. lowercase. * cc-mode.el (c-functionp): Emacs 19.3x doesn't have functionp, so lift the version from XEmacs 19.13. (c-electric-brace, c-read-offset, c-set-offset, c-get-offset): Use c-functionp. Fri May 31 14:42:07 1996 Barry A. Warsaw * cc-mode.el (c-offsets-alist): New syntactic symbols: extern-lang-open, extern-lang-close, inextern-lang (c-hanging-braces-alist): Hang extern-lang-open by default. (c-electric-brace): Add extern-lang-open and extern-lang-close to list of symbols that can hang. (c-guess-basic-syntax): CASE 5A.4 => 5A.5; New CASE 5A.4 added to recognize extern-lang-open; CASE 14C => 14D; New CASE 14C added to recognize extern-lang-close (c-recognize-knr-p): defconst it. (c-search-uplist-for-classkey): When searching for c-class-key, concat "\\|extern[^_]". The logic for determining whether we are inclass-p and inextern-p is essentially the same so this seems to work very well in all test cases. (c-guess-basic-syntax): If inclass-p, do an additional check to see whether this is really inside an external language definition block or a class definition and set inextern-p accordingly (a boolean only). (c-guess-basic-syntax): CASE 5A.4 => 5A.1; 5A.1-5A.3 => 5A.2-5A.4; New CASE 5F to check for extern-lang-close; CASE 5F-5J => 5G-5K; CASE 5I: modifier could either be 'inclass or inextern-lang; CASE 14A: closing brace isn't an inline-close if we're inside an extern language block; CASE 14B: watch out for same. Thu May 30 14:42:07 1996 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5A.3: an inline-open brace should also be given inclass syntax. The problem is that this breaks indentation for brace that start inline-inclass functions inside a nested class since they will twice add the indentation of the inner class to the running total. The solution is to not give one of the two symbols a relpos. The decision was made to omit the relpos of the 'inline-open symbol. (c-mode-help-address): Added cc-mode-help@python.org as the new address. (c-recognize-knr-p, c++-mode, java-mode): Made into a non-user configurable variable. This variable is always t for C and Objective-C modes and nil for C++ and Java modes. (c-guess-basic-syntax): CASE 5G: Although we still test on c-recognize-knr-p, this is no longer user configurable, and no longer imposes potentially disasterous impact on performance. Adopt c-mode.el assumption that argdecls are indented at least one space and that function headers are not indented. This prevents us from potentially searching back to the top of the file when looking at a large number of top-level delarations. (c-gnu-impose-minimum): New function (c-label-minimum-indentation): New buffer-local variable (c-style-alist): In "gnu" style, add c-gnu-impose-minimum to c-special-indent-hook so case-label and label syntaxes will have a minimum indentation. (c-submit-bug-report): report on c-label-minimum-indentation (c-set-style-1): special case c-special-indent-hook make c-special-indent-hook buffer local Wed May 29 20:13:34 1996 Barry A. Warsaw * cc-mode.el (c-skip-conditional): `try' clauses in C++ skip only 1 sexp. Also take care of finally and synchronized statements. Fri May 24 15:30:27 1996 Barry A. Warsaw * cc-mode.el (c-lineup-arglist-close-under-parent): New function. (c-C-conditionals): New constant. (c-C-conditional-key, c-C++-conditional-key, c-Java-conditional-key): Use c-C-conditionals. (c-Java-conditional-key): Added support for "synchronized" keyword. Fri May 3 22:03:13 1996 Barry A. Warsaw * cc-mode.el (c-Java-conditional-key): New variable. (java-mode): Set buffer-local variable c-conditional-key to c-Java-conditional-key. Thu May 2 21:18:56 1996 Barry A. Warsaw * cc-mode.el (c-C++-access-key): Allow for whitespace between the protection key and the colon. Wed Apr 10 04:50:50 1996 Barry A. Warsaw * cc-mode.el (c-set-style): as a last resort, match exact case for stylename. Wed Apr 3 16:19:08 1996 Barry A. Warsaw * cc-mode.el (c-get-offset, c-read-offset, c-set-offset): Use functionp instead of fboundp to test for OFFSET being a function. This makes the documentation more accurate and allows for lambda expressions to be used as offsets, instead of allowing only symbols with function bindings. Mon Apr 1 16:12:27 1996 Barry A. Warsaw * Public Release 4.282 Tue Feb 6 22:35:36 1996 Barry Warsaw * cc-mode.el (c-common-init): typo Mon Feb 5 15:54:08 1996 Barry Warsaw * cc-mode.el (c++-mode-map, objc-mode-map, java-mode-map): In XEmacs, use set-keymap-parents if it is fboundp. * cc-mode.el (c-delete-backslash): Sync with old-c-mode.el. Given by Ben Wing . Mon Jan 22 23:25:21 1996 Barry Warsaw * cc-mode.el: Added back autoload cookies. * cc-mode.el (c-emacs-features): Determine which paragraph filling regexp suite to use based on the Emacs version number. (c-fill-paragraph): Use the paragraph filling regexp suite as determined in c-emacs-features. Fri Jan 19 18:57:01 1996 Barry Warsaw * cc-mode.el: imenu is required in Emacs 19, but doesn't exist in XEmacs * cc-mode.el (c-site-default-style): New variable. Thu Jan 18 23:51:17 1996 Barry Warsaw * cc-mode.el: (java-mode, java-syntax-table, java-mode-map, java-mode-abbrev-table): New in support of Java. Tue Jan 16 00:09:41 1996 Barry Warsaw * cc-mode.el (c-common-init): Make comment-multi-line a local variable. Mon Jan 15 23:56:06 1996 Barry Warsaw * cc-mode.el (c-set-style): Conditional up-casing of stylename for backwards compatibility. Fri Jan 12 02:07:54 1996 Barry Warsaw * cc-mode.el (c-backward-to-start-of-do): Eliminate infinite loop in perverse cases. * cc-mode.texi: Explain that style names are case insensitive. * cc-mode.el (c-style-alist, c-set-style, c-add-style): All style names are case insensitive, but default to lowercase. Sat Jan 6 01:08:45 1996 Barry Warsaw * cc-mode.el (cc-imenu-c++-generic-expression): New variable. Integrated w/ FSF changes. (cc-imenu-c-generic-expression): New variable. Integrated w/ FSF changes. (c++-mode): Set imenu-generic-expression. Integrated w/ FSF changes. (c-mode): Set imenu-generic-expression. Integrated w/ FSF changes. (c-common-init): Make imenu-generic-expression buffer local. * cc-mode.el (c-progress-fini): Integrate RMS change: Fix "done" message. * cc-mode.el (c-electric-lt-gt): New command. * cc-mode.el (c-mode-map): Only rebind M-q if fill-paragraph-function doesn't exist, as in pre-Emacs 19.30. Integrated with FSF changes. (c-common-init): Set fill-paragraph-function if it exists. Integrated with FSF changes. (c-fill-paragraph): Return t if did special filling. Otherwise return nil and don't change the buffer. Integrate with FSF changes for Emacs 19.30. * cc-mode.el: Switch to GNU style only the first time file is loaded. * cc-mode.el (c-guess-basic-syntax): CASE 5B.3: ansi-funcdecl-cont could include legal C++ `throw' declaration. (c-offsets-alist): ansi-funcdecl-cont => + Fri Jan 5 23:14:12 1996 Barry Warsaw * cc-mode.el (c-beginning-of-statement-1): Restore old CASE 3 logic -- checking for at a c-conditional-key. (c-guess-basic-syntax): CASE 5A.2: watch out for enum function return types. CASE 15D: check for landing on a brace that opens a nested function. Wed Nov 22 14:55:12 1995 Barry Warsaw * (c-beginning-of-statement-1): CASE 3, can't just return t at end of let clause since this will break arglist-cont-nonempty lines (see buggy line below). Doing a backward-up-list could be slow, but I don't see any other way of doing this. void C_entries (c_ext, inf) int c_ext; /* extension of C */ FILE *inf; /* input file */ { /* Consider token only if some complicated conditions... */ if ((definedef != dnone || (cblev == 0 && structdef != scolonseen) || (cblev == 1 && structdef == sinbody)) /* buggy line */ && typdef != tignore && definedef != dignorerest && funcdef != finlist) { } } Fri Nov 17 22:01:36 1995 Barry Warsaw * cc-mode.el (c-guess-basic-offset, c-beginning-of-statement-1): Do not check for c-conditional-key when skipping backwards over statements that look sort of like conditionals. This makes statements following nested functions indent correctly. CASE 9B.3 (unknown catchall) now gets triggered by the brace that opens a nested function. These will get indented moderately correctly, but they are not assigned the correct syntax. I'm not sure exactly what they *should* be assigned. Also, this changes the relpos for top-level defun-open braces, but that will be very hard to fix, and it may break backward compatibility. * cc-mode.el (c-guess-basic-offset): CASE 5H, inclass relpos should be relative to boi of the open brace, not the beginning of the class keyword. Thu Nov 16 00:20:59 1995 Barry Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5D.5, watch out for c-access-key set to nil, as in this case (in c-mode): typedef struct { unsigned count:24, age:6, dirty:1, reserved:1, }; Wed Nov 15 23:38:05 1995 Barry Warsaw * cc-mode.el (c-beginning-of-statement, c-end-of-statement): Watch out for c-end-of-statement being called interactively. Mon Aug 28 20:39:43 1995 Barry Warsaw * cc-guess.el (cc-guess-region): wrap relpos calculation in a save-excursion. Mon Aug 28 16:57:26 1995 Barry Warsaw * Version 4.241 released. Mon Aug 21 23:41:21 1995 Barry Warsaw * cc-mode.el (c-backslashify-current-line): Obsolete. (c-append-backslash, c-delete-backslash): Taken from XEmacs' old-c-mode.el (c-backslash-region): Use the version from XEmacs' old-c-mode.el since it does a better job of aligning the backslashes. * cc-mode.el (c-indent-defun): Watch out for point being on the first top-level open brace in the buffer. Tue Aug 1 22:14:32 1995 Barry Warsaw * cc-mode.el (c-copy-tree, c-mapcar-defun): Define functions only available in XEmacs 19.12, or Emacs 19 + lucid.el. Tue Jul 25 22:27:37 1995 Barry Warsaw * cc-mode.el (c-lineup-ObjC-method-call): New implementation better handles 1. indentation of arguments to keyword parameters, 2. multiline method calls. Fri Jul 21 22:08:04 1995 Barry Warsaw * cc-mode.texi (Customizing Indentation): Added a better explanation of the difference between setq and setq-default w.r.t. setting cc-mode indentation variables. Thu Jul 20 20:19:33 1995 Barry Warsaw * cc-mode.el (c-electric-brace): Fixed preservation of no-whitespace before brace. * cc-mode.el (c-guess-basic-syntax): CASE 5A.1: Watch out for c-state-cache; it may or may not be in place, but it should be ignored. * cc-mode.el (c-electric-colon): In call to c-lookup-lists, fixed incorrect quoting of symbols in the quoted list. Mon Jul 10 15:44:55 1995 Barry Warsaw * cc-mode.el (c-search-uplist-for-classkey): Watch out for embedded c-class-key keywords. Mon Jul 3 18:05:33 1995 Barry Warsaw * cc-mode.el (c-common-init): Make a deep copy of c-offsets-alist so that changing the buffer-local value in one buffer doesn't affect the global value, or other buffers. * cc-mode.el (c-snug-do-while): forward-sexp call could fail; wrap it in a c-safe. Fri Jun 30 21:42:23 1995 Barry Warsaw * cc-mode.el (c++-mode, objc-mode): comment-multi-line must be nil if // is the default comment style. Sun Jun 11 18:05:20 1995 Barry Warsaw * cc-mode-18.el (c-emacs18-bsws): Installed while loop patch given by "David P. Baker" to fix infinite loops when lim is reached while still inside whitespace. Sun Jun 11 16:58:39 1995 Barry A. Warsaw * Version 4.222 Released. Sun Jun 11 18:05:20 1995 Barry A. Warsaw * cc-mode-18.el (c-emacs18-bsws): installed while loop patch given by "David P. Baker" to fix infinite loops when lim is reached while still inside whitespace. Thu Jun 1 16:51:16 1995 Barry A. Warsaw * cc-mode.el (c-hack-state): watch out for null state with 'open brace. Tue May 30 23:11:57 1995 Barry A. Warsaw * cc-mode.el (c-outline-level): new function. (c-common-init): compatibility with outline-minor-mode. Given by Per Abrahamsen Fri May 19 00:15:06 1995 Barry A. Warsaw * cc-mode.el (c-electric-colon): when adding a newline for a non- `before' -hanging colon, watch out for when they already start on their own line. Thu May 18 23:49:51 1995 Barry A. Warsaw * cc-mode.el (paragraph-start, paragraph-separate): backed out of the 4.191 -> 4.192 change due to breakage in c-fill-paragraph and dabbrev-expand. Wed May 17 22:51:46 1995 Barry A. Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5C: more robust in searching for c-baseclass-key when not followed by a colon. * cc-mode.el (c-enable-//-in-c-mode, c-setup-dual-comments): new functions to allow users to optionally enable // as comment delimiters in c-mode. (c-C-comment-start, c-C++-comment-start): new variables. (c-mode, c++-mode, objc-mode): use new variables. * cc-mode.el (c-guess-basic-syntax): CASE 5D.4: watch out for <> characters in literals. CASE 5D.5: skip forward over any literals encountered after point. Mon May 8 23:11:35 1995 Barry A. Warsaw * cc-mode.el (c-set-style): Ignore case in completion. Use appropriate mode name in prompt string. * cc-mode.el (c-in-literal): Faster implementation for skipping over cpp macros, at the expense of prohibiting `#' characters as first non-whitespace char on a line inside another literal (i.e. string or block comment). Wed May 3 22:52:32 1995 Barry A. Warsaw * cc-mode.el (c-read-offset): change to have an interface consistent w/ switch-to-buffer Mon May 1 20:31:13 1995 Barry A. Warsaw * cc-mode.el (c-style-alist): fixed the 'label offset for GNU, K&R, BSD, Stroustrup, and Whitesmith. Sat Apr 29 00:46:53 1995 Barry A. Warsaw * cc-mode.el (c-mode-map): C-c C-v unbound since it conflicts with OOBR, which has a more useful binding. Mon Apr 17 16:48:06 1995 Barry A. Warsaw * cc-mode.el (c-lineup-ObjC-method-call): Installed Lele Gaifax patch as suggested by mccallum@cs.rochester.edu for Objective-C method call indentation styles. Wed Apr 12 21:02:46 1995 Barry A. Warsaw * cc-mode.el (paragraph-start, paragraph-separate): Installed the FSF's patch as explained below: Thu Mar 2 10:22:30 1995 Boris Goldowsky * ada.el (ada-mode): Remove "^" used as anchor from paragraph-start and paragraph-separate values, so that they will work with non-0 left-margin settings. [...] * cc-mode.el (c-common-init, c-fill-paragraph): Likewise. * cc-mode.el (c-hanging-semi&comma-criteria): new variable (c-semi&comma-inside-parenlist): new function (c-electric-semi&comma): use new variable c-hanging-semi&comma-criteria to determine if a newline should be added after a semicolon or comma, instead of hardcoding this logic in. Mon Apr 10 22:00:28 1995 Barry A. Warsaw * cc-mode.el (c-electric-brace): When hanging a close brace, add just-one-space if there was already whitespace before point. Fri Mar 31 01:15:07 1995 Barry A. Warsaw * cc-mode.el (c-offsets-alist, c-read-offset, c-set-offset, c-get-offset): added two new offset shortcuts, '* and '/ which stand for *0.5 and *-0.5 respectively. * cc-mode.el (c-beginning-of-statement-1): added a new CASE 4 to catch labels just above the current line. Thu Mar 30 19:00:02 1995 Barry A. Warsaw * cc-mode.el (c-protection-key, c-symbol-key): had to move these before c-baseclass-key which uses them. Wed Mar 29 23:11:57 1995 Barry A. Warsaw * cc-mode.el: (c-baseclass-key, c-mode, c++-mode, objc-mode, c-guess-basic-syntax): This can be nil in all modes other than c++-mode. Make this variable buffer local and it saves one looking-at call in the c-guess-basic-syntax tight loop. Mon Mar 27 23:18:30 1995 Barry A. Warsaw * cc-mode.el (c-recognize-knr-p): default value is nil for all modes. Wed Mar 22 16:45:53 1995 Barry Warsaw * cc-mode.el: CC-MODE style has to make a deeper copy of non-atomic lists * cc-mode.el: set "GNU" style just after creating the CC-MODE style * cc-mode.el: added c-recognize-knr-p and c-hanging-comment-ender-p variables to "CC-MODE". * cc-mode.el (c-C++-friend-key): new constant (c-guess-basic-syntax): use c-C++-friend-key to find friend declarations. Note that template class friends don't start with the word "friend". * cc-mode.el (c-indent-region): wrap a backward-sexp call in a c-safe to avoid bogus error conditions. Mon Mar 20 23:58:32 1995 Barry Warsaw * cc-mode.el: Only add the "CC-MODE" style and set the "GNU" style on the first load of cc-mode.el (not (featurep 'cc-mode)). (c-guess-basic-syntax): skip over case/default labels before skipping over other labels. * cc-mode.el (c-style-alist, c-set-style): "Default" style is renamed to "CC-MODE" style so as not to confuse matters (too much). * cc-mode.el (c-indent-comments-syntactically-p): new variable (c-comment-indent): use c-indent-comments-syntactically-p instead of comment-column==nil to control M-; acting like TAB. The latter behavior was too broken to work correctly. Mon Mar 13 22:09:46 1995 Barry Warsaw * cc-mode.el (c-mode): setq comment-multi-line to t. * cc-mode.el (c-common-init): (c-set-style "GNU") moved out of this defun and into the top level of cc-mode.el. This is pushed down towards the bottom of the file, to just after the calculation of the "Default" style. Also, the style variables are not made buffer local until after this call. Seems kludgy that its all order dependent, but it addresses the problem of setq-default at the .emacs top level not doing the expected thing. Thu Mar 9 21:31:28 1995 Barry Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5J: Watch out for c-beginning-of-statement-1 leaving us at bob with a following comment. * cc-mode.el (c-comment-indent): When comment-column is nil, indent according to c-offsets-alist, i.e. behavior is identical to hitting TAB. * cc-mode.el (c-guess-basic-offset): CASE 5D.5: skip over any access specifiers found if inclass-p. CASE 5D.1: looking at a hanging member init colon only if not attached to an access specifier. * cc-mode.el (c-guess-basic-syntax, c-lineup-comment): TAB should always indent comment-only lines according to c-offsets-alist. It should never pin comments appearing at comment-column. Use M-; for that. * cc-mode.el (c-common-init): Default mode is now GNU * cc-mode.el (c-styles-alist): Mention the Default style. * cc-mode.el (c-offsets-alist-default): obsolete (c-offsets-alist): now contains default values. These will always be captured in the "Default" style and all styles now inherit from "Default". (c-offsets-alist, c-basic-offset, c-comment-only-line-offset, c-block-comments-indent-p, c-cleanup-list c-hanging-braces-alist, c-hanging-colons-alist, c-hanging-comment-ender-p, c-backslash-column): All variables are now buffer-local. (c-set-style-1): new function (c-set-style): 1. removed &optional local argument -- use make-variable-buffer-local instead if buffer local style settings are desired; 2. Reset the style to "Default" before instituting the new style. This means all styles derive from the "Default" style. Sat Mar 4 00:41:01 1995 Barry Warsaw * cc-mode.el (c-comment-only-line-offset): Fixed the docstring to follow current semantics of the variable. (c-style-alist): Fixed GNU style for c-comment-only-line-offset to '(0 . 0) so that column zero comments will not anchor. * cc-mode.el: Moved the setup of the "Default" style to further down in the file. Also, this uses the new c-add-style API. * cc-mode.el (c-add-style): Added set-p flag for optional setting of the style. * cc-mode.el (c-conditional-key, c-class-key, c-comment-start-regexp): setq-default their values to the `C' values so that non-cc-mode-ized modes that rely on BOCM behavior still work (e.g. awk-mode). Wed Mar 1 21:30:56 1995 Barry Warsaw * cc-mode.el (c-add-style): New command. * cc-mode.el (c-backward-to-start-of-if): better error message for orphaned else error. It now prints the line number of the orphaned else. * cc-mode.el: added pending-delete and delete-selection properties for proper co-operation with pending-del and delsel modes. Thu Feb 16 01:38:27 1995 Barry Warsaw * cc-mode.el (c-hack-state): it is legal for cdr to be nil when 'close brace is encountered. Do we need the (consp car) test??? (c-guess-basic-syntax): CASE 5H: Removed the test for preceding-char = to ?:. This fixes two problems. First, in objc-mode, there is no colon after access specifiers. Also, some people might use macros for PRIVATE and PROTECTED, and these also don't have trailing colons. Wed Feb 15 15:38:37 1995 Barry Warsaw * cc-mode.el (c-electric-brace): when ACTION is a function, the second argument is the buffer position the brace was inserted, regardless of any implementation details (i.e. may not be the same as where the brace actually resides during the callout). (c-hanging-braces-alist): update docstring to new callout semantics. Tue Feb 14 19:54:50 1995 Barry Warsaw * cc-mode.el (c-beginning-of-statement-1): when looking for an else-if clause, watch out for #else gotchas. Mon Feb 13 23:14:51 1995 Barry Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 5D.3: syntactic symbol should be 'inher-cont instead of 'inher-cont-1. Wed Feb 8 22:52:15 1995 Barry Warsaw * cc-mode.el (c-electric-brace): In punt section, nil out the syntax cache too, since its out-of-date. Tue Feb 7 17:38:42 1995 Barry Warsaw * cc-mode.el (c-electric-brace): When hanging the brace, figure out when to punt and recalculate the entire state. Mon Feb 6 17:07:45 1995 Barry Warsaw * cc-mode.el (c-whack-state): New function. (c-electric-brace): use c-whack-state to adjust state when inserting hanging closing braces. Thu Feb 2 16:49:21 1995 Barry Warsaw * cc-mode.el (c-adjust-state): New function (c-electric-brace): make sure state is adjusted when preceding lines are re-indented via c-indent-line. Mon Jan 30 16:49:10 1995 Barry Warsaw * cc-mode.el (c-safe-position): takes a buffer position and a state list since it must determine a safe position farther up the buffer than the give buffer position. (c-electric-brace): use new c-safe-position call sequence (c-guess-basic-syntax): CASE 14: when finding relpos, and calling c-b-o-s-1, lim must be higher in buffer than containing-sexp, so call c-safe-position to find this position. Wed Jan 18 15:47:11 1995 Barry Warsaw * cc-mode.el (c-electric-brace): When c-auto-newline is nil, no newlines or re-indentation is performed. * cc-mode.el (c-guess-basic-syntax): CASE 9D: after-cond-placeholder can be nil, tripping up (max ...). Tue Jan 17 14:52:02 1995 Barry Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 15D: safepos should be c-most-enclosing-brace of fullstate. This could potentially be slower, but it is accurate. * cc-mode.el (c-guess-basic-syntax): CASE 15F: Watch out for lim == point. In that case, use (c-safe-position state) as the most enclosing known safe buffer position. Mon Jan 16 23:55:43 1995 Barry Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 9D: Kludged fix for c-beginning-of-statement-1 possibly leaving us at a buffer position before lim `after-cond-placeholder'. c-b-o-s-1 should be fixed, but I'm worried about side-effects at this point. It will be fixed in v5. * cc-mode.el (c-crosses-statement-barrier-p): Do not reset lim if, after skipping characters, point is inside a literal. Point in a literal, is not considered safe. Wed Jan 4 23:57:11 1995 Barry Warsaw * cc-mode.el (c-snug-do-while): Watch out for non-hanging open brace on `do'. * cc-mode.el (c-electric-brace): In (memq 'before newlines) clause, when updating the c-state-cache, point can be <= the (car of c-state-cache) for us to strip out the most enclosing brace. * cc-mode.el (c-electric-delete): Added delete-selection and pending-delete 'supersede properties for proper "delete-erases-current-selection" behavior. Wed Dec 28 16:05:02 1994 Barry Warsaw * cc-mode.el (c-indent-exp): Don't try to call c-progress-fini if c-progress-init was never called (i.e. due to error having been signaled). Wed Dec 21 00:28:24 1994 Barry Warsaw * cc-mode.el (c-electric-brace): If the temporary newline must be deleted (because it hangs), use delete-indentation instead of the delete-region hackery. * cc-mode.el (c-snug-do-while): New function. (c-hanging-braces-alist, c-cleanup-list, c-electric-semi&comma): To eliminate the newline between the brace that closes a `do' block and the following `while', make the c-hanging-braces-alist ACTION for 'block-close be 'c-snug-do-while by default. There is no more need for the 'snug-do-while cleanup. Tue Dec 20 23:51:52 1994 Barry Warsaw * cc-mode.el (c-electric-brace): In updating the cache during the 'before section, watch out for c-state-cache being nil. * cc-mode.el (c-electric-brace): Implement new semantics for c-hanging-braces-alist. Also, fix state cache during re-indentation of preceding line when 'before newline is added. Mon Dec 19 23:30:47 1994 Barry Warsaw * cc-mode.el (c-intersect-lists, c-lookup-lists): New functions. (c-electric-brace, c-electric-colon): Use the new functions to simplify the flow of logic in determining hanginess. * cc-mode.el (c-hack-state): When adding a close brace, watch out for balanced block sitting on list in car of cdr position. * cc-mode.el (c-electric-semi&comma): Some minimal efficiency additions by including a backscan limit. * cc-mode.el (c-electric-semi&comma, c-cleanup-list): Added a new clean-up: snug-do-while which will snuggle the `while' of a do-while up to after the closing brace. * cc-mode.el (c-lineup-objc-method-args, c-lineup-objc-method-call, c-offsets-alist-default, c-beginning-of-statement-1, c-guess-basic-syntax): Jumbo Lele Gaifax Objective-C patch. Fri Dec 16 15:41:05 1994 Barry Warsaw * cc-mode.el (c-guess-basic-syntax): CASE 10: watch out for false else clauses (e.g. else_thing). Wed Dec 14 23:11:59 1994 Barry Warsaw * cc-mode.el (c-postprocess-file-styles): Renamed from c-find-file-hook. Hang this off of hack-local-variables-hooks, which won't be supported until future Emacs 19's. Tue Dec 13 23:58:48 1994 Barry Warsaw * cc-mode.el (c-beginning-of-statement-1): Watch out for lim! * cc-mode.el (c-hack-state, c-safe-position): New functions. (c-electric-brace, c-parse-state, c-inside-brace-list-p, c-guess-basic-syntax): Implemented two major performance enhancements used both in general, but also specifically during brace insertion. First, call c-beginning-of-statement-1 directly instead of wasting time in the user-command version. Second, and most importantly, implement a c-parse-state cache so that the brace state for a particular line doesn't have to be completely recalculated 4 times for every brace insertion. Mon Dec 12 20:20:49 1994 Barry Warsaw * cc-mode.el (c-inside-bracelist-p): Fixed aggregate logic w.r.t. failures in forward-sexp. * cc-mode.el (c-inside-bracelist-p): Order of magnitude improvement in performance by eliminating often costly calls to c-backward-syntactic-ws. Fri Dec 9 23:39:31 1994 Barry Warsaw * cc-mode.el (c-inside-bracelist-p): Special case speed up for when most enclosing brace of brace-state is nil. Sat Sep 10 13:27:11 1994 Barry A. Warsaw (warsaw@anthem.nlm.nih.gov) * Public Release of 4.85. Wed Sep 7 18:41:29 1994 Barry A. Warsaw, ITB * cc-mode.el (c-mode-fsf-menu, c-mode-map, c++-mode-map, objc-mode-map): use a better feature test to figure out how to set the menu title string. Tue Sep 6 13:49:46 1994 Barry A. Warsaw, ITB * cc-mode.el (c-search-uplist-for-classkey): in `class' keyword verification section, only skip forward for ?> template char if a matching ?< char was found previous to search-start. This eliminates false match of template base classes. Thu Sep 1 22:30:23 1994 Barry A. Warsaw, ITB * cc-mode.el (c-submit-bug-report): updated var list * cc-mode.el (c-mode-fsf-menu, c-mode-map, c++-mode-map, objc-mode-map): do a better job of getting the menu title string appropriate for the mode being edited in. Bogus, but necessary. XEmacs is better in this respect. * cc-mode.el (c-search-uplist-for-classkey): Lele patch for objc-mode * cc-mode.el (c-search-uplist-for-classkey): avoid "invalid search bound" error * cc-mode.el (c-beginning-of-statement-1): skip special modifier chars in all cases, not just in "no balanced expr found" case. * cc-mode.el (c-guess-basic-syntax): CASE 9: generalize and collect common code for finding position after conditional statements, and check for `while' statement of a `do' loop. In that case, skip over the trailing semi. Wed Aug 31 22:20:47 1994 Barry A. Warsaw, ITB * cc-mode.el (c-progress-init, c-progress-update, c-progress-fini): use a marker for end (and be sure to free it!) so that as indentation occurs, % can't go above 100. * cc-mode.el (c-mode-map): check on feature (fboundp 'add-menu) for FSF 19 (which doesn't have it). * cc-mode.el (c-progress-info, c-progress-init, c-progress-update, c-progress-fini): new vars/defuns for better long indentation progress reporting (c-indent-exp, c-indent-region): use new progress reporting Tue Aug 30 21:57:37 1994 Barry A. Warsaw, ITB * cc-mode.el (c-guess-basic-syntax): CASE 6F, go forward 1 char from b-o-s of containing-sexp bufpos to find proper relpos of an arglist-cont. * cc-mode.el (c-offset-alist-default): statement-case-open default offset is zero (c-skip-case-statement-forward): new function (c-guess-basic-syntax): CASE 15: use c-skip-case-statement-forward in proper places to find the real relpos of statement's inside switch case/default bodies. CASE 15D: remove special handling when looking at c-conditional-key. * cc-mode.el (c-offsets-alist, c-cleanup-list, c-mode-menu, c-mode-map, c-symbol-key, c-indent-line, c-popup-menu): make sure ObjC is properly documented. * cc-mode.el (c-least-enclosing-brace): new function (c-enclosing-brace, c-guess-basic-syntax): renamed c-enclosing-brace to c-most-enclosing-brace (c-indent-defun): handle opening braces not in column 1 * cc-mode.el (c-beginning-of-statement-1): skip over statement mod characters that don't preceed an open paren. Fri Aug 26 17:42:24 1994 Barry A. Warsaw, ITB * cc-mode.el (c-guess-basic-syntax): be careful to check for c-access-key non-nil before calling (looking-at c-access-key). For C, this is nil. * cc-mode.el (c-beginning-of-statement-1): swapped CASE 3 and 4, so that conditional statements are picked up properly * cc-mode.el (c-guess-basic-syntax): CASE 15D, calculate relpos from boi of beginning of statement prior to indent-point, unless we're looking at a conditional key * cc-mode.el (c-mode-map, c++-mode-map, objc-mode-map): change test of 'FSF in c-emacs-features to an fboundp set-keymap-parent test Thu Aug 25 13:31:31 1994 Barry A. Warsaw, ITB * cc-mode.el (c-just-after-func-arglist-p, c-guess-basic-syntax, c-lineup-objc-method-args-2): more objc patches from Lele Wed Aug 24 21:06:05 1994 Barry A. Warsaw, ITB * cc-mode.el (c-indent-command): with optional arg, shift-amt had wrong sign * cc-mode.el (c-lineup-arglist): better handling of comments preceding arg lists * cc-mode.el (c-guess-basic-syntax): swapped CASE 6A and 6B so that empty arglists with close paren on separate line are properly recognized. * cc-mode.el (c-mode-menu, c-emacs-features, c-mode-map, c-common-init): remove dependency on string "Lucid" in emacs-version. Use features based means where such descrimination is necessary. Tue Aug 23 18:43:28 1994 Barry A. Warsaw, ITB * cc-mode.el (c-fill-paragraph): merge with c-mode.el uses fill-region-as-paragraph * cc-mode.el (c-offsets-alist-default, c-offsets-alist, c-hanging-braces-alist, c-electric-brace, c-guess-basic-syntax): added syntactic symbol statement-case-open for statement-case-intro's that contain an open brace. * cc-mode.el (c-lineup-math): watch for equal signs in literals * cc-mode.el (c-beginning-of-statement-1): CASE5 and CASE 6, better pick up of label's with potential embedded colons (scope operators). Mon Aug 22 22:28:03 1994 Barry A. Warsaw, ITB * cc-mode.el (c-hanging-comment-ender-p): new variable (c-fill-paragraph): looks at c-hanging-comment-ender-p to see if */ should be left on its own line. c-mode.el behavior is default value t, but there have been *many* requests for nil's behavior. Wed Aug 17 23:05:01 1994 Barry A. Warsaw, ITB * cc-mode.el (c-recognize-knr-p, c-common-init): fix the way this var is made buffer local Tue Aug 16 20:05:49 1994 Barry A. Warsaw, ITB * cc-mode.el (c-recognize-knr-p, c-mode, c++-mode, objc-mode): make it so c-recognize-knr-p is settable from c-mode-common-hook. Thu Aug 11 20:40:06 1994 Barry A. Warsaw, ITB * cc-mode.el (c-recognize-knr-p): new variable (c-offsets-alist-default, c-offsets-alist, c-guess-basic-syntax): changed syntactic symbol c++-funcdecl-cont to ansi-funcdecl-cont (c-mode, c++-mode, objc-mode): use new c-recognize-knr-p variable (c-guess-basic-syntax): use new c-recognize-knr-p variable; swap CASE 5B.2 and 5B.3. Wed Aug 10 17:54:53 1994 Barry A. Warsaw, ITB * cc-mode.el (c-offsets-alist, c-read-offset, c-set-offset): can accept variable symbols as offsets. (c-get-offset): can now accept ++ and -- symbols, which evaluate to 2* positive and negative c-basic-offset. Thu Aug 4 15:29:43 1994 Barry A. Warsaw, ITB * cc-mode.el (c-guess-basic-syntax): case 9C added small performance improvment to c-in-literal call Wed Aug 3 17:37:30 1994 Barry A. Warsaw, ITB * cc-mode.el (c-beginning-of-statement-1): use c-in-literal-cache, and limit backscanning in CASE 5 to known, non-literal position. * cc-mode.el (c-in-literal, c-guess-basic-syntax): caching of last literal result Tue Aug 2 20:18:10 1994 Barry A. Warsaw, ITB * cc-mode.el (c-guess-basic-syntax): CASE 15D, calculate 'statement relpos as the beginning-of-statement relative to indent-point. * cc-mode.el (c-beginning-of-statement-1): CASE 4, check for conditional keywords which could be followed by a balanced paren expr. I.e. while(foo) Tue Jul 26 15:55:21 1994 Barry A. Warsaw, ITB * cc-mode.el (c++-mode-syntax-table, objc-mode-syntax-table): give CR same syntax as newline, for selective-display. Fri Jul 22 18:42:38 1994 Barry A. Warsaw, ITB * cc-mode.el (c-electric-star): fixed indentation problem when a star is not preceded by a slash. * cc-mode.el (c-indent-defun): removed condition-case inside unwind-protect. All error conditions are properly handled at other levels of the code. Thu Jul 21 22:34:19 1994 Barry A. Warsaw, ITB * cc-mode.el (c-class-key, c-search-uplist-for-classkey): greatly simplified, this constant now contains a regexp that only matches valid `class' keywords, in the C++ sense. It now ignores any template, extern, static, etc. keywords. Tue Jul 19 09:53:37 1994 Barry A. Warsaw (warsaw@anthem.nlm.nih.gov) * Public Release of 4.35. Sun Jul 17 18:29:51 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-syntax): Lele Gaifax's patch to fix an Objc problem... "this patch, applied to 4.32, will correct a little bug in ObjC mode. Currently objc-mode fails to recognize a continued arglist, as it guesses every such construct is a continued method call." Fri Jul 15 13:48:39 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-search-uplist-for-classkey): don't get fooled by the following C construct: struct shmid_internal shmconv( register int s) { int foo = 1; } Tue Jul 12 14:36:10 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-parse-state): in body of `something bad happened' part, don't use beginning-of-defun to find "real" bod since based on some coding styles, this could loop us all the way back to bob. E.g.: int foo() { int a = 7; { foobar(); }} int foo() { int a = 7; { foobar(); }} Instead use scan-lists and be more robust about crossing unbalanced close braces. Now even antisocial coding styles like the above can be quickly parsed correctly. * cc-mode.el (c-parse-state): small but important fix in `something bad happened' test. make sure that placeholder close brace ends up before indent point, otherwise we didn't cross it. Thu Jul 7 13:56:08 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-parse-state): in `something bad' section, placeholder will always be just after any close brace so we need to 1- from it to check for ?}. Also, we probably don't need to check for placeholder-1 being nil. Thu Jun 30 21:03:55 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-switch-label-key): a paren can follow the `case' keyword without any intervening whitespace. * cc-mode.el (c-beginning-of-statement-1): when skipping over unary ops, remember that whitespace could be intermixed before the paren * cc-mode.el (c-electric-brace): added brace-list-intro and brace-list-entry to list of hangables (c-hanging-braces-alist): added docstring for b-l-i and b-l-e hangability * cc-mode.el (c-beginning-of-statement-1): CASE 6: be sure to ignore switch labels too. * cc-mode.el (c-lineup-arglist-intro-after-paren): new lineup function to conform to GNU style. (c-style-alist): for style GNU, arglist-intro set to c-lineup-arglist-intro-after-paren and arglist-close set to c-lineup-arglist to conform to BOCM GNU style. Wed Jun 29 00:48:56 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-syntax): installed this patch: In ObjC mode 4.6 the tests 6D and 6E in c-guess-basic-syntax need to be swapped. Otherwise what is a continued method call line will be recognized as a 'arglist-cont-nonempty. Swapping these test will not interfere with the normal behaviour of cc-mode, since the test for the method call is surrounded with a test on (eq major-mode 'objc-mode). Emanuele (lele) Gaifax | ...calling Emacs convenient, of course, is lele@nautilus.sublink.org | like calling oxygen useful -- Rens Troost * cc-mode.el (c-mark-function): new implementation based on c-parse-state. I think this should work much better for people. Tue Jun 28 23:57:42 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-just-after-func-arglist-p): partial fix for this bug: class foo { foo() : // member-init-intro a (0), // topmost-intro-cont??? b (0) // member-init-cont {} }; note that if there is a comment after foo(), its still broken. But that probably won't happen too often... * cc-mode.el (c-lineup-arglist): don't limit skippages forward over syntactic ws to eol. Mon Jun 27 18:25:42 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-parse-state): when looking to see if `something bad happened', and guaranteeing that the char-after placeholder is = to ?}, make sure that char-after placeholder is less than point-max (i.e. char-after placeholder returns non-nil). * cc-mode.el (c-electric-star): should not re-indent line if introducing a comment not on a comment-only line Thu Jun 23 17:54:49 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-inside-bracelist-p): when finding an enum, check to be sure its not a type descriptor on a return value of a func (i.e. skip-chars-forward for not semi or open paren). Wed Jun 22 19:23:43 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-parse-state): when trying to find out if "something bad happened" be sure to check for crossing a close *brace* and not a close paren or square bracket. Only crossing a close brace indicates badness. Mon Jun 20 00:32:46 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-set-offset): initial contents of prompt is the last syntactic symbol on the syntactic analysis list -- the most likely symbol that the user wants to change. Fri Jun 17 22:25:41 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-arglist): fixed problem of skipping too many close parens when finding the relpos of arglist-close. * cc-mode.el (c-guess-basic-syntax): CASE 6F fixed incorrect relpos * cc-mode.el (c-guess-basic-syntax): CASE 8B and CASE 8C: when an otherwise brace-list-entry or brace-list-intro is found to start with an open brace, the line is given brace-list-open syntax instead (c-inside-bracelist-p): fix small bug in recognizing open brace at brace-list-intro line, and infinite loop problem. * cc-mode.el (c-inside-bracelist-p): more accurate handling of nested aggregates. Now uses brace-state as provided by c-parse-state. Tue Jun 14 22:25:09 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-forward-conditional): break infinite loop when finding commented out conditionals Mon Jun 13 17:40:08 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-submit-bug-report): Use new interface for reporter.el 2.x Fri Jun 10 13:42:02 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-submit-bug-report): remove defun-prompt-regexp from the list of vars if it is not boundp (i.e. v18) Thu Jun 9 14:15:00 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-syntax): repaired all CASE numbers * cc-mode.el (c-offsets-alist-default): added syntactic symbols objc-method-intro objc-method-args-cont objc-method-call-cont. (c-offsets-alist): added descriptions for above new syntactic symbols (objc-mode-hook) (objc-mode-abbrev-table) (objc-mode-map) (objc-mode-syntax-table) (objc-mode): added for Objective-C support (c-objc-method-key): new regexp desribing an ObjC method intro. (c-electric-slash): objc-mode understands // comments (c-fill-paragraph): objc-mode understands // comments (c-beginning-of-statement-1): added CASE 7 for objc-mode (c-in-objc-method-def-p): checks to see if inside an Objective-C method definition. (c-just-after-func-arglist-p): check for Objective-C method def (c-guess-basic-syntax): many modifications to look for Objective-C syntactic symbols: CASE 3.5, CASE 4G, CASE 4I, CASE 5E. (c-lineup-objc-method-call) (c-lineup-objc-method-args): new custom lineup functions for Objective-C methods. (c-submit-bug-report): look for ObjC mode Mon Jun 6 19:47:19 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-style-alist): another fix to Ellemtel style. Since the style guide recommends braces around the body of all case statements, statement-case-intro should be 0, letting statement-block-intro of the following line pick up the proper indentation * cc-mode.el (c-style-alist): Ellemtel style should have c-hanging-braces-alist for substatement-open be before and after Thu Jun 2 23:09:16 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-strict-syntactics-p): changed to c-strict-syntax-p (c-guess-basic-syntactics): changed to c-guess-basic-syntax (c-add-syntactics): changed to c-add-syntax (various): use new function and variable names Wed Jun 1 15:46:19 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: bumping to version 4 in anticipation of objc-mode support Tue May 31 23:51:08 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-strict-semantics-p): changed to c-strict-syntactics-p (c-echo-semantic-information-p): changed to c-echo-syntactic-information-p (c-semantics): changed to c-syntactic-context (c-guess-basic-semantics): changed to c-guess-basic-syntactics (c-show-semantic-information): changed to c-show-syntactic-information (cc-mode.el): other internal changes to make terminology consistent * cc-mode.el (c-guess-basic-semantics): CASE 14.E, if defun opening brace is not at boi, its because its hung on right side so we need a different relpos * cc-mode.el (c-guess-basic-semantics): CASE5, various. Extend the notion of arglists to bracket lists, i.e. [...] * cc-mode.el (c-search-uplist-for-classkey): when skipping over commas after classkey's watch out for inheritance lists... * cc-mode.el (c-beginning-of-statement-1): ignore labels and access keys Tue May 24 22:04:15 1994 Barry A. Warsaw, ITB (warsaw@anthem) * Public Release 3.349 * cc-mode.el (c-search-uplist-for-classkey): break out of infinite loop when finding `struct' keyword in arglist Mon May 23 15:43:07 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-electric-brace): we need to recalculate semantics if, when re-indenting the preceding line, point changes. If this happens, the relpos for semantics is invalid. Thu May 19 22:27:55 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-style-alist): updated the various styles to set the correct values for substatement-open (c-style-alist): added dynamic setting of default style. The way this works may or may not be a feature? Wed May 18 22:07:15 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-backward-to-start-of-if): fix to correctly handle `else-if' clauses, which should be skipped when looking for the matching if. * cc-mode.el (c-search-uplist-for-classkey): don't get confused by a single struct type arg in a function's arglist * cc-mode.el (c-beginning-of-statement-1): on backward-sexp failure, skip over funny chars and whitespace only when just before a paren (c-search-uplist-for-classkey): watch out for comma ending struct arg declarations which doesn't leave us in a class definition. * cc-mode.el (c-mode-map): fix the setting of mode-popup-menu for Lemacs 19.10. Menu must have a title string. * cc-mode.el (c-style-alist): changes to Ellemtel style: substatement sets its offset to 3, substatement-open sets its offset to 0. Given by: Lars Lindberg. Tue May 17 22:46:22 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-beginning-of-statement-1): when backward-sexp fails and doing backward-up-list, and before skipping over noise characters, skip over any preceding syntactic whitespace: --------------V if ( ! backup_dev || sep1 != ':' || ) * cc-mode.el (c-beginning-of-statement-1): fixed small infinite loop in CASE5 test when barrier char is in literal. * cc-mode.el (c-guess-basic-semantics): CASE 13: don't limit the search backwards for the beginning of statement * cc-mode.el (c-beginning-of-statement-1): completely rewritten to properly account for cpp macros and statement barrier characters (e.g. { } ;) in literals. Mon May 16 20:21:12 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-inside-bracelist-p): must check that enum keyword truly introduces a bracelist and not that it is a type identifier for a declaration. I.e. match: enum foo { /* ... */ } but not: enum foo bar; Thu May 12 22:52:12 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): CASE 4A.2 watch out for enum keywords in K&R argdecl lists. These don't open enum definitions, but they are declarations instead. E.g.: ret_stat (rpt_stat, filename, pcode) enum xrpt_status_codes rpt_stat; char filename[]; enum xpippop_codes pcode; { * cc-mode.el: (c-C-conditional-key) (c-C++-conditional-key): new regexps which describe conditionals in the two supported languages. This is necessary because `try' and `catch' blocks are defined as substatements equivalent to `while', `for', etc., in C++ only (c-mode) (c++-mode): set c-conditional-key, which is now buffer-local, to either c-C-conditional-key or c-C++-conditional-key. * cc-mode.el (c-parse-state): when we discover that an open brace we thought specified the bod, actually isn't the bod, we backup and search for another potential bod. This is necessary so that open braces in column zero that aren't really defun opening braces don't trip us up. Our test for invalid bod is if we cross over an unbalanced close brace. * cc-mode.el (c-guess-basic-semantics): CASE 4G, in c-mode, fix recognition of the last line in the following construct: typedef int (*foobar) /* if I break this into 2 lines ...*/ (int foo, char *bar); extern foobar really; /* this is incorrectly indented */ Tue May 10 16:42:13 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-indent-region): fixed a bug where comment-only lines were being skipped. Wrapped an unwind-protect around mark copying so we can't leak marks. * cc-mode.el (c-emacs-feature): use variables emacs-major-version and emacs-minor-version if they exist Fri May 6 21:09:58 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-style-alist): small changes to the Ellemtel style: inline-open and topmost-intro-cont are changed to 0 offset. * cc-mode.el (c-hanging-braces-alist): added (substatement after) so that braces will hanging on substatement blocks Thu May 5 22:48:23 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-math): can now line up equals signs even if the equals isn't at boi. E.g., it can now handle: float a = 1.0, b = 7, c = 9; * cc-mode.el (c-comment-start-regexp): new buffer-local variable which describes how comments start. This improves generality for C-like modes with different comment intro styles. * cc-mode.el (c-indent-via-language-element): renamed to c-indent-line for better backwards compatibility, i.e. awk-mode Tue Apr 26 16:17:29 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-parse-state): make sure we ignore any bogus beginning-of-defun bufpos's when we're searching back 2 bods * cc-mode.el (c-search-uplist-for-classkey): after finding what looks like a class header, search for both a semi (denoting a fwd decl), and an equals (denoting a struct init). Thu Apr 21 21:12:26 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c-electric-brace) (c-electric-semi&comma) (c-electric-colon) (c-indent-command) (c-indent-exp) (c-indent-region) (c-indent-via-language-element): eliminated extraneous optional arguments, i.e. lim and bod * cc-mode.el (c-adaptive-block-open): obsolete (c-offsets-alist-default) (c-electric-brace): added substatement-open syntactic symbol (c-hanging-braces-alist): added ability to hang substatement-open braces. (c-style-alist): changed defaults of block-open to substatement-open * cc-mode.el (c-safe): use Dan LaLiberte's version impl. workaround for an FSF 19.22 bug Tue Apr 19 15:15:41 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-mode-map): put c-macro-expand on C-c C-e * cc-mode.el: (c-mode-map) (c-common-init): put in code to conform to Lucid 19.10's popup menu convention of using mode-popup-menu variable Fri Apr 15 23:09:59 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-indent-defun): handle buffer-read-only errors better * cc-mode.el (c-lineup-math): also lines up multi-line equal signs * cc-mode.el (c-guess-basic-semantics): replaced calculation of literal which must have gotten accidentally removed some time ago. * cc-mode.el (c-1bit-il): removed since it appears to be identical to c-in-literal, and thus obsolete. * cc-mode.el (c-search-uplist-for-classkey): programmatically ignore the `class' keyword inside template arg lists (c-enclosing-brace) (c-narrow-out-enclosing-class): new helper functions (c-guess-basic-semantics): fixed recognition of 'defun-open CASE 4A.4, CASE 13.A, 'block-close CASE 13.B, 'defun-block-intro CASE 14.E Thu Apr 14 18:42:00 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-parse-state): record containing paren, but not balanced paren sexps * cc-mode.el (c-guess-basic-semantics): fixed a regression problem in recognizing the difference between an inline-close and a nested class-close * cc-mode.el: (c-parse-state) (c-guess-basic-semantics) (c-search-uplist-for-classkey): massive rewrite of all parsing components. c-parse-state now uncovers the brace nesting level of the construct from (bod 2) to point and the other two defuns use this information to make scooting around brace levels much quicker and more accurate. Thu Apr 7 14:34:28 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-electric-brace): can now specify `hanginess' on close braces Thu Mar 31 15:10:09 1994 Barry A. Warsaw, ITB (warsaw@anthem) * Public release: 3.304 * cc-mode.el (c-search-uplist-for-classkey): class relpos should be at the 'boi of where c-class-key gives us a match. This is because its too hard to make c-class-key match the typedef keyword on: typedef struct Foo { so its easier to make this fix instead. Fri Mar 25 20:34:18 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c-forward-syntactic-ws) (c-backward-syntactic-ws): minor speed ups achieved by calling forward-comment with a huge number so we don't have to return to the lisp loop after just 1 comment. * cc-mode.el (c-search-uplist-for-classkey): added another speedup where syntactic whitespace is skipped before doing a re-search-forward. This requires however that the buffer be narrowed during the r-s-f because of the definition of c-class-key which matches \\` or empty-string-at-bod. It would be better to use \\`\\|\\= to match empty-string-at-point, but that's not defined for v18, and doesn't seem to work anyway, at least in Lemacs. (c-search-uplist-for-classkey): after finding a match for c-class-key, skip non-semicolons up to brace point. If a semi is found, we're looking at a forward declaration, not a class definition. Thu Mar 24 18:43:38 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): do not limit calls to c-search-uplist-for-classkey to just c++-mode since even in C we can have nested structs and unions. (c-search-uplist-for-classkey): now returns a vector instead of a cons cell (c-guess-basic-semantics): modifications for new c-s-u-f-c return value * cc-mode.el: (c-inside-bracelist-p) (c-guess-basic-semantics): when looking for an enum brace-list, c-beginning-of-statement could leave us at point-min, which could contain an intervening comment, so you need to call c-forward-syntactic-ws. Wed Mar 23 23:22:37 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-search-uplist-for-classkey): another fix for infinite loops that can occur when indenting inside the second of multiple nested classes. This should also speed things up by further limiting the region being searched. Tue Mar 22 23:12:58 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-mark-function): worked around call to backward-paragraph, which didn't work and wasn't the right semantics anyway. Movement should be by beginning-/end-of-defun. * cc-mode.el (c-indent-exp): restructure the unwind-protect call to ensure that the `end' marker is always removed on any error condition. (c-indent-exp): find any open brace that occurs after point, ignoring lexical whitespace, including newlines. * cc-mode.el (c-inside-bracelist-p): in the first goto-char, goto containing-sexp, not 1- c-s, otherwise, it will not properly recognize bracelists with comments on the end of the line. The following c-beginning-of-statement will properly consume any preceding whitespace. Mon Mar 21 22:01:25 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-search-uplist-for-classkey): must handle nil return value from scan-lists. * cc-mode.el (c-search-uplist-for-classkey): fix problem of infinite loops when there are balanced expressions between (bod 2) and the indent-point that aren't picked up by bod because they don't match defun-prompt-regexp. We skip over this noise with scan-lists. * cc-mode-18.el: don't hack c-emacs18-common-hook onto c-mode-common-hook anymore. tell users to put it on their c-mode-common-hook themselves. * cc-mode.el (c-search-uplist-for-classkey): end-of-defun can fail Fri Mar 18 21:38:31 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-search-uplist-for-classkey): new performance tuned version. Here are some numbers: hitting tab at the end of an 11k function, with an 8k function just before it was giving me 2.637sec for c-indent-command, and 1.784sec for c-s-u-f-c alone. Now I'm getting 0.972sec for c-i-c and 0.180sec for c-s-u-f-c. An order of magnitude improvement in c-s-u-f-c. These are un-bc'd times. Other bottlenecks must exist in c-i-c... * cc-mode.el: added an eval-when-compile to pick up the reporter-* symbols when byte-compiling. Thu Mar 17 20:56:04 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-electric-colon): do scope-operator clean up immediately after self-insert-command so that subsequent indentation and hanging calculations will be performed correctly Tue Mar 15 23:29:16 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-search-uplist-for-classkey): adjust for the fact that c-class-key now match 1 character before the `c' in "class". goto-char 1+ foundp to get to the proper character starting the class definition. * cc-mode.el (c-read-offset): new helper function for c-set-offset (c-set-offset): sanity check OFFSET argument both interactively and non-interactively. This seems to trip up many novices. * cc-mode.el (c++-mode-map): fixed binding for c-scope-operator. It is now on C-c : Fri Mar 11 23:45:51 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode-18.el (c-emacs18-il): applied patch contributed by SAKAI Kiyotaka(ksakai@mtl.t.u-tokyo.ac.jp) to fix infinite loop bug. * cc-mode.el (c-fill-paragraph): removed last 2 c-mode.el dependencies * cc-mode.el (c-guess-basic-semantics): CASE 8C: after moving to placeholder, which is bos, move over any conditional statments if looking at c-conditional-key. Otherwise the following code indents incorrectly: main() { while (cin >> float) cout << float << float; // This should not be this far over but beneath << } * cc-mode.el (c-indent-exp): put an unwind-protect around the sanity checks so that point is restored on error * cc-mode.el (c-class-key): another fix to recognize keyword `class' at beginning-of-buffer. (c-guess-basic-semantics): if class opening brace is not the last non-whitespace on a line, the narrow-to-region narrowing out of enclosing class will not have the proper begin point. Make sure the region does not contain the class opening brace. * cc-mode.el (c-indent-region): fixed error signal when indenting region not containing balanced sexp. e.g. at the top level: int i, j, k; * cc-mode.el (c-class-key): another fix to recognize nested class but not the word 'class' in a template declaration Thu Mar 10 23:32:37 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-beginning-of-statement-1): sped up about 8x by removing an unnecessary (I think) call to c-backward-syntactic-ws and a duplicate call to c-in-literal. By using elp, I think these were the real time hogs in c-b-o-s-1 which was the biggest hog in c-guess-basic-semantics. Wed Mar 9 22:15:26 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-arglist): added a (beginning-of-line) call before the (backward-up-list 1) call in the special case for arglist-intro and arglist-cont-nonempty. Without this, indentation would be different when point was at the beginning and end of line. E.g.: main() { if ((BuddyRec* buf = (BuddyRec*)(bufs[message_bufs++] = ::new unsigned char[MessageBufSize])) == 0) { } } On the "== 0) {" line. * cc-mode.el (c-indent-exp): try to be smarter about finding the beginning of the balanced expression to indent. Gives results closer to old indent-c-exp behavior. * cc-mode.el (c-submit-bug-report): moved the require of reporter to after the y-or-n-p question. Shortened the package name so it will fit on the Subject line better. Mon Mar 7 17:39:45 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-skip-conditional): new function. factorized duplicate code (c-guess-basic-semantics): fixed statement-cont relpos calculation in a continued statement following an else clause. CASE 8A and 8D changed to use c-skip-conditional. Mon Feb 28 18:23:36 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-conditional-key): not sufficient to wrap conditional keywords in \\<...\\> since this will false hit a keyword followed by an underscore, which technically isn't a keyword. An example is "do_table" which incorrectly gets marked as a `do' keyword. Fri Feb 25 23:01:45 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): swapped CASE 7A and 7B so that we properly indentify a brace-list-close of an empty brace list. * cc-mode.el (c-style-alist): added the "Ellemtel" style which implements the coding style defined in "Programming in C++, Rules and Recommendations, Erik Nyquist and Mats Henricson, Ellemtel, ftp from euagate.eua.ericsson.se". * cc-mode.el: (c-point) (c-indent-defun): only check the value of defun-prompt-regexp if it is boundp (so v18 doesn't break) Thu Feb 24 23:34:08 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-electric-brace): fixed bug in temporary newline insertion when auto-newline is off. If a temp newline was not inserted, don't try to delete it later on. * cc-mode.el (c-set-offset): changed the minibuffer prompt. "Langelem" => "Syntactic symbol", and put in a brief message so that people won't quote the symbol (as some novices have been doing). * cc-mode.el (c-guess-basic-semantics): CASE 4B.1, check for member init colon preceding point even after doing a forward-char -1. Need to skip over constructor parameter list that span multiple lines, with the member init colon hanging on the last of those line. CASE 4D.1. added a backward-sexp call to handle member-init-cont's which are paren-lists broken across multiple lines. * cc-mode.el (c-inhibit-startup-warnings-p): new variable, used in c-emacs-features (c-emacs-features): rewrote feature extraction logic to be based on version numbers. This more closely reflects the current state of affairs of the main Emacs flavors. There is sanity checking and warning messages built-in too, to help inform the user if there are known problems. Mon Feb 21 18:13:53 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): swap case 4A.2 and 4A.3 so that brace-lists are checked before inline-open's, otherwise enums inside of classes are not recognized properly. * cc-mode.el (c-backslashify-current-line): use kill-region instead of kill-line so we don't have to use the kill-lines-magic hack. * cc-mode.el (c-beginning-of-statement-1): do not register last-begin when looking at a case/default label, otherwise statement-cont lines after a case label will not be associated with the correct beginning-of-statement Fri Feb 18 16:13:27 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-arglist): must handle arglist-intro lines just like arglist-cont-nonempty lines in the calculation of containing-sexp in the let* statement. (c-lineup-arglist): do not hard-code offset to 2 if at the end, we are still looking at the eol. I don't know why that was there... * cc-mode.el (c-guess-basic-semantics): CASE 4I, topmost-intro-cont's relpos must be the boi of the beginning-of-statement, otherwise multiple t-i-c lines get marching indentation. Thu Feb 17 23:53:16 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-set-style): changed the sense of the optional argument. Now, style changes modify the global variables by default, except when a non-nil second argument is given. Only then are buffer-local versions of the variables made. * cc-mode.el (c-lineup-arglist): fixed calculation of containing-sexp for the following code: main() { if( someFunction(someArg, anotherArg) && someOtherFunction(someArg, anotherArg)) doThis(); } * cc-mode.el (c-class-key): fixed class recognizing regexp so that it doesn't falsely match the word `class' in a template function declaration, e.g.: template int A::foo( * cc-mode.el (c-mode-map): moved c-indent-defun to C-c C-q. This should be its final resting place (c-lineup-math): new optional custom indent function, not used by default. * cc-mode.el (c-mode-map): moved c-indent-defun from C-M-x to C-c C-i. RMS says C-M-x is reserved. Wed Feb 16 23:06:15 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-mode-syntax-table): change : back to default (. == punctuation) syntax class since c-label-key is busted when its (_ == symbol) * cc-mode.el (c-lineup-runin-statements): new lineup function for people who hang the first statement after the open brace. (c-offsets-alist-default): added comment about alternative indentation style for `statement' Mon Feb 14 15:53:30 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-point): when defun-prompt-regexp is non-nil, b-o-d doesn't leave us at the brace, so we need to skip it as noise. * cc-mode.el (c-indent-defun): if defun-prompt-regexp is non-nil, beginning-of-defun won't leave us at the open brace, so we must skip over defun-prompt-regexp... its noise. Fri Feb 11 20:49:19 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): CASE 14.C, when looking for a ?: construct, and checking for not looking at a :: scope operator, make sure we do this comparison at indent-point, instead of the first non-blank line in the block * cc-mode.el (c-guess-basic-semantics): CASE 8C: if first stream-op is on a separate line (i.e. not on the `cout' line), it should be indented like a statement-cont, not a stream-op. Relpos in this case is boi of the first preceding non-syntactic-ws line * cc-mode.el: (c-backward-to-start-of-if) (c-backward-to-start-of-do) (c-guess-basic-semantics): It is not enough to search test for looking-at "keyword\\b" since this will not catch "keyword_thing", which is a valid symbol and not a keyword. There is no equivalent of \\b that matches at the end of a word-or-symbol string. For now, I changed the looking-at's to "keyword\\b[^_]" which seems to work. There are probably instances of "keyword\\>" that are broken too, but we'll hit them as they occur, since I'm not sure they are broken. Thu Feb 10 23:30:11 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-populate-syntax-table): only put c-mode/c++-mode common syntax entries into syntax table. (c++-mode-syntax-table): colon (:) gets symbol class * cc-mode.el: (c-mode-hook) (c++-mode-hook) (c-mode-common-hook): added defvars for completeness. Wed Feb 9 17:48:21 1994 Barry A. Warsaw, ITB (warsaw@anthem) * Public release: 3.229 * cc-mode.el (c-electric-braces): when calculating the initial semantics of the open brace, we only need to insert a temporary newline if there is non-whitespace preceding the brace, on the same line. * cc-mode.el (c-guess-basic-semantics): CASE 4I, don't add `inclass' semantics to the list since the relpos already has any inclass offset added in. Otherwise we get inclass offsets added twice. * cc-mode.el (c-guess-basic-semantics): fixed small problem introduced in version 3.235. when skipping lexical whitespace, we must skip [ \t\n]. newline wasn't getting skipped. Tue Feb 8 22:05:48 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c-offsets-alist) (c-offsets-alist-default): added `friend' syntactic symbol for recognition of C++ friend declarations. Default offset is 0. (c-guess-basic-semantics): recognize C++ friend declarations, and add `friend' syntactic symbols as a modifier. * cc-mode.el (c-guess-basic-semantics): when narrowing out enclosing class, and calculating start of region to narrow to, do not skip all syntactic ws, just lexical whitespace (change c-forward-syntactic-ws call to skip-chars-forward). Otherwise, you could skip into the middle of a C comment block and not figure out that what you're looking at is a `c' syntactic symbol. * cc-mode.el: (c-offsets-alist) (c-offsets-alist-default) (c-guess-basic-semantics): added defun-block-intro syntactic symbol which controls indentation for the first line in a top-level defun, analogous to statement-block-intro. (CASE 14.E) * cc-mode.el (c-indent-defun): catch any errors that occur in c-indent-exp and make sure point is restored and the temporary mark is destroyed. * cc-mode.el: (c-untame-characters) (c-backscan-limit) (c-tame-insert) (c-tame-comments) (c-emacs18-fsws) (c-emacs18-bsws) (c-emacs18-il): moved these defuns and vars to cc-mode-18.el file. (c-mode-map): do not install Emacs 18-only bindings (c-populate-syntax-table): do not install Emacs 18-only syntax table entries (c-insert-and-tame): renamed to c-insert-special-chars and make this call only self-insert-command. Don't worry about Emacs 18 compatibility. (c-mark-function) (c-common-init): Don't worry about Emacs 18 compatibility. (c-emacs19-accurate-fsws): renamed to c-forward-syntactic-ws. Don't worry about Emacs 18 compatibility. (c-emacs19-accurate-bsws): renamed to c-backward-syntactic-ws. Don't worry about Emacs 18 compatibility. (c-8bit-il): renamed to c-in-literal. Don't worry about Emacs 18 compatibility. (c-submit-bug-report): remove reporting of c-backscan-limit and c-untame-characters since these are for Emacs 18 only. Wed Feb 2 00:00:40 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-arglist): add kludge for arglist-cont-nonempty to get correct indentation. (c-guess-basic-semantics): CASE 5D: arglist-cont-nonempty's relpos needs to be boi of containing-sexp paren. this is good for + offset, but bad for c-lineup-arglist, so add the kludge described above. Tue Feb 1 22:14:35 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-inside-bracelist-p): enum keyword could be preceded by a typedef keyword * cc-mode.el (c-comment-region): removed as obsolete, use comment-region instead. Put the new comment-region function in, but commented out. * cc-mode.el (c-default-macroize-column): changed to c-backslash-column. Default value changed to 48 from 78. This is merged from c-mode.el (c-macroize-region): changed to c-backslash-region for c-mode.el merge. Mon Jan 31 22:57:05 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): CASE 8B.3: instead of try-block-open, which is now gone, put statement-cont, block-open on semantics list. Eventually I may call a recognition hook, and/or exceptions probably fall through to here. * cc-mode.el (c-guess-basic-semantics): CASE 5E. go to beginning of statement before looking getting relpos, so that we properly pick up nested argument lists. * cc-mode.el (c-common-init): better setting up of Lucid menubar (use mode-name as menu bar title) (c-popup-menu): use mode-name in menu title * cc-mode.el (c-keep-region-active): shouldn't check for interactive-p in tests (c-submit-bug-report): don't keep region active. * cc-mode.el (c-keep-region-active): no-op for FSF 19 (c-set-style) (c-beginning-of-statement) (c-end-of-statement) (c-up-conditional) (c-backward-conditional) (c-forward-conditional) (c-popup-menu): added a call to c-keep-region-active (c-tame-comments) (c-indent-command) (c-indent-exp) (c-indent-defun) (c-indent-region) (c-macroize-region) (c-comment-region): removed call to c-keep-region-active Sun Jan 30 20:22:09 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-mode-map): remapped c-toggle-hungry-state to C-c C-d so it would not interfer with standard C-c C-h key prefix help mapping Fri Jan 28 22:16:29 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-switch-label-key): fixed what can occur between the `case' keyword and the colon. Its any amount of whitespace, followed by a single, non-whitespace character, followed by any number of other characters. Thu Jan 27 21:15:57 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-fill-paragraph): much better for C++ style comments. 1. does not munge up font-lock regions by inserting/deleting the intended fill-prefix. 2. does not assume that leading whitespace before // is spaces, *but* fill-prefix must be consistent for every line in the region. * cc-mode.el (c-mode-menu): moved this higher up in file * cc-mode.el (c-end-of-statement): simple paren mismatch in call to c-beginning-of-statement * cc-mode.el (c-guess-basic-semantics): CASE 2, skip over any preceding blank lines that can occur before the comment. This fixes comment indentation for the second and following paragraphs in a multi-paragraph C block comment region with no leading stars. (c-lineup-C-comment): don't assume relpos is at the beginning of the line (even though it usually is). * cc-mode.el (c-switch-label-key): simplify description of what can follow a 'case' tag * cc-mode.el: Use copy-alist instead of c-copy-sequence * cc-mode.el (c-common-init): fix the way c-mode-menu is added to the Lucid menubar so existing menubars aren't clobbered * cc-mode.el (c-copy-sequence): workaround for FSF 19.22 bug in copy-sequence Wed Jan 26 22:38:20 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-comment): renamed from c-indent-for-comment (c-lineup-comment): call c-comment-indent when a comment-only line's indentation is at or to the right of comment-column. (c-guess-basic-semantics): when a comment-only line's indentation is at or to the right of comment-column, only 'comment-intro is on the semantics list since the comment does not indent relative to a non-comment line would get indented. * cc-mode.el (c-lineup-arglist): now correctly handles arglist-close langelems (i.e. closing parens in an arglist) * cc-mode.el (c-offsets-alist-default): new constant containing unchanging default settings for langelems (c-offsets-alist): value is set as a distinct copy of c-offsets-alist-default. (c-set-style): if 'c-offsets-alist is found in style, first reset the value of this variable to c-offses-alist-default, then change only those langelems that differ. * cc-mode.el (c-style-alist): changed defconst to defvar. removed comments from c-mode merge * cc-mode.el (c-indent-region): minor format change * cc-mode.el (c-indent-region): merged in RMS's latest c-indent-region. Added a skip of blank lines before the current line is indented. Recalculate beginning-of-defun lim inside of top-level while loop so that back-parsing is further restricted properly, speeding indentation calculation. Tue Jan 25 18:01:01 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-fill-paragraph): small fix to RMS's paren level typo * cc-mode.el (c-fill-paragraph): fixed (hopefully) obvious parenthesis level typo * cc-mode.el (c-fill-paragraph): added RMS's new C++ aware version (c-mode-map): put back the binding of M-q to c-fill-paragraph Mon Jan 24 22:52:53 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-update-modeline): typo: use c-hungry-delete-key * cc-mode.el (c-auto-hungry-string): minor-mode-alist variable (c-common-init): auto-hungry designation string happens on minor-mode-alist now (c-update-modeline): sets the c-auto-hungry-string * cc-mode.el (c-electric-semi&comma): only re-indent line when c-auto-newline is non-nil * cc-mode.el (c-mode-menu): new Lucid menu variable for popup and menubar (c-popup-menu): command for popping up a menu in Lemacs (c-mode-map): FSF 19's menu initialization stuff is moved to here. Add binding for Lemacs to put c-popup-menu on button 3. (c-common-init): put c-mode-menu on buffer-local menubar for Lucid Fri Jan 21 22:36:03 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c-up-block) (c-down-block): removed. backward-up-list and down-list do the job already * cc-mode.el: (cc-mode.el) comment improvements (c-mode-map): a few merges from lemacs, but commented out for now. (c-insert-brackets) (c-insert-braces): taken from lemacs, but commented out for now (cc-mode.el): menus added from FSF emacs. Still need menus for lemacs. Fri Jan 14 18:59:57 1994 Barry A.

Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-mode.el): only v19 has the make-obsolete calls * cc-mode.el (c-guess-basic-semantics): CASE 8B.3 now returns a try-block-open, but exceptions aren't yet fully supported. * cc-mode.el (c-beginning-of-statement): when in a comment, or looking at the beginning of a comment, only call forward-sentence if not called interactively. Thus programmatically, this function always goes back to the real beginning-of-statement. * cc-mode.el (cc-mode.el): changes to comments at top of file * cc-mode.el: (c-common-init) (c-style-name) (c-set-style): removed c-style-name, and no longer put style name on minor mode list * cc-mode.el: (c-set-style) (c-style-alist): vastly verbosified docstrings Tue Jan 11 23:50:45 1994 Barry A.

Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-set-offset): conversion of offset to a number in the interactive list glom section was missing negative numbers due to the leading minus sign * cc-mode.el (c-beginning-of-statement-1): on error, skip backwards over +!~ in addition to other chars skipped Sat Jan 8 03:20:49 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-electric-pound): fixed after-functionality positioning when point is at bolp before # is installed * cc-mode.el (c-guess-basic-semantics): CASE 13, inline-close relpos should be boi of the beginning-of-statement relpos * cc-mode.el (c-beginning-of-statement-1): only do the skip-chars-backwards in the failure of the condition-case statement. also, add the `-' character to the list of skippage Fri Jan 7 23:27:20 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-beginning-of-statement-1): do not let backward scanning stop inside a literal. use c-in-literal to stop this, which really catches only preprocs * cc-mode.el (c-guess-basic-semantics): CASE 13, block-close relpos should be boi of relpos to catch "} else {" constructs * cc-mode.el: (c-forward-conditional) (c-indent-region) (c-beginning-of-inheritance-list) (c-backward-to-start-of-do) (c-backward-to-start-of-if): removed unused let-bound variables as per output of byte compiler * cc-mode.el: better messages about the necessary makunbounds Thu Jan 6 18:52:51 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-beginning-of-statement-1): recognize "else if" clauses (c-guess-basic-semantics): CASE 8A recognizes "else if" clauses Mon Jan 3 23:01:58 1994 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: upped the copyright notice date * cc-mode.el (c-beginning-of-statement-1): before calculating last-begin, skip over any bogus characters like *&:. for the following situations: if(::foo(), if(.0123, if(&blatz, if(*bar, * cc-mode.el (c-guess-basic-semantics): CASE 8A. do and else clauses aren't followed by a paren list, so we should only skip forward over 1 sexp in those cases. Wed Dec 29 18:06:12 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-lineup-multi-inher): skip syntactic ws if there is only a comment on the end of the line containing the opening colon * cc-mode.el (c-guess-basic-semantics): CASE 5C, don't check for c-conditional-statement, since only "for" can have multiple substatements * cc-mode.el (c-guess-basic-semantics): CASE 8: added colon to list of characters that don't continue a statement, all other cases will be caught later on (I hope). * cc-mode.el (c-guess-basic-semantics): rewrote and re-arranged CASE 5 subcases to correctly identifiy for-list substatements, etc. looks like paren-lists now work pretty well. Tue Dec 28 16:36:06 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): fixed CASE 5C to use new semantics for c-beginning-of-statement. * cc-mode.el (c-beginning-of-statement-1): make sure searching stops correctly at conditional statements (if/while,...etc) so that substatements are properly recognized * cc-mode.el (c-beginning-of-statement): make sure we're left at or after lim * cc-mode.el: (c-electric-brace) (c-electric-slash) (c-electric-star) (c-electric-semi&comma) (c-electric-colon): let-bind c-echo-semantic-information-p to nil to shut up information printing in inappropriate places * cc-mode.el (c-guess-basic-semantics): fixes to CASE 8 for new semantics of c-beginning-of-statement. Added a test of placeholder != containing-sexp in top-level test. CASE 8D, progn => save-excursion so correct statement start can be found * cc-mode.el: (c-beginning-of-statement) (c-end-of-statement): minor clean up. removed my old c-beginning-of-statement -- we'll go with FSF's and fix it as need bee Mon Dec 27 23:25:17 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c-beginning-of-statement) (c-end-of-statement): add another optional argument, lim (c-guess-basic-semantics): corrected to use new arg list for the above * cc-mode.el: (c-beginning-of-statement) (c-end-of-statement): check for argument == nil (optional arg not supplied) * cc-mode.el: (c-beginning-of-statement) (c-end-of-statement): make arg optional * cc-mode.el (c-beginning-of-statement, et al): try using BOCM's version to see if it works any better * cc-mode.el (c-set-style): put a space in front of c-style name (c-common-init): only hack on c-style-name once! * cc-mode.el: provide cc-mode, not c-mode * cc-mode.el (c-style-name): new variable, buffer local (c-common-init): hack on c-style-name to the minor-mode alist (c-set-style): set c-style-name variable for minor-mode * cc-mode.el (c-conditional-key): added "switch" (c-guess-basic-semantics): renumbered CASE 8 subcases, no substantive changes. (c-guess-basic-semantics): added dummy CASE 8B.3 to generate an error. I don't know what constructs fall through this case. * cc-mode.el (c-symbol-key): put this back in and fixed all the other -key's to use it * cc-mode.el (c-set-auto-hungry-state): small typo in check for force-mode-line-update * cc-mode.el: use force-mode-line-update where appropriate * cc-mode.el: added autoload directives Wed Dec 22 20:52:32 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-inside-bracelist-p): fixed a bug when no spaces were between the = char and open brace in an aggregate list * cc-mode.el (c-switch-label-key): fixed to recognize negative numbers * cc-mode.el: (c-forward-into-nomenclature) (c-backward-into-nomenclature): new commands, but as yet unbound * cc-mode.el (c-guess-basic-semantics): CASE 7C: look for block-open modifier Tue Dec 21 22:55:21 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): CASE 7 improved but nested brace-lists are still not perfect. Do I need to add another langelem??? blech. * cc-mode.el (c-inside-bracelist-p): new function to calculate whether we're inside a brace list or not (c-guess-basic-semantics): use c-inside-bracelist-p where appropriate * cc-mode.el (c-guess-basic-semantics): CASE 7B's (brace-list-close) relpos is not boi of bo-stmt, instead its boi of containing-sexp * cc-mode.el (c-offsets-alist): added brace-list-close, brace-list-intro, brace-list-entry (c-guess-basic-semantics): added logic to recognize brace-list-open new langelems * cc-mode.el (c-hanging-braces-alist): docstring addition: brace-list-open (c-offsets-alist): added brace-list-open (c-electric-brace): added logic to hang brace-list-open's (c-guess-basic-semantics): added logic to recognize brace-list-open's * cc-mode.el (c-mode-map): removed binding to undefined c-match-paren * cc-mode.el (c-semantics): new variable (c-indent-via-language-element): use globally advertised c-semantics variable now. (c-offsets-alist): better docstring, describes c-semantics * cc-mode.el (c-adaptive-block-open): new function, but block-open doesn't use it by default yet (c-guess-basic-semantics): moved M2 (block-open) test into body of defun instead of at the end -- to many special case tests Mon Dec 20 17:55:38 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-indent-command): guarantee that c-tab-always-indent == nil has the same semantics as in BOCM * cc-mode.el (cc-mode.el): pulled in bocm's beginning-of-statement, end-of-statement and related defuns, but I still need to make a pass through them. (c-up-conditional) (c-backward-conditional) (c-forward-conditional): yanked in verbatim from c-mode.el (c-backslash-region): fset from c-macroize-region. also, we're leaving c-backslash-column commented out. use c-default-macroize-column instead. * cc-mode.el (c-fill-paragraph): removed, use filladapt instead (c-comment-indent): adopted from c-mode.el, but fixed to handle C++ comments * cc-mode.el (c-mode.el): moved some defuns and defmacros around. no substantive changes * cc-mode.el (c-symbol-key): obsolete, use \\s_ syntax class instead (c-protection-key): new defconst (c-case-statement-key): renamed to c-switch-label-key * cc-mode.el (c-lineup-streamop): search for stream operator, be careful of singular less than, greater than symbol. Fri Dec 17 21:42:27 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed semantics for c-macroize-region and c-comment-region * cc-mode.el (c-guess-basic-semantics): don't put block-open on semantics list if other brace open symbols are already there Thu Dec 16 20:49:34 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-emacs-features): minor docstring change * cc-mode.el (c-set-offset): new optional add-p arg. when non-nil, require-match on completion is inhibited and new langelem symbols can be added to the c-offsets-alist. (c-guess-basic-semantics): CASE 7C has been extended to properly recognize conditional's substatements. CASE 7D now handles continued statements. CASE 7A now recognizes only func local class opening braces, which means 7C + M2 will catch substatement block-opens. (c-offsets-alist): added substatement langelem * cc-mode.el (c-strict-semantics-p): default value to nil for debugging purposes (c-guess-basic-semantics): block-open langelem is now a relpos-less langelem because it is really a modifier on the basic langelem of the line. Specifically: Case M2 added; CASE 7A.2 now places just a statement-cont langelem on semantics; CASE 13.B is completely removed. (c-offsets-alist): block-open default offset is now 0. Mon Dec 13 15:29:26 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): now it does the the test for c++-mode to save a potential funcall in c-mode. (c-search-uplist-for-class): fixed bug where c-in-literal test was testing end-point of parse-partial-sexp, not the classkey search begin point. Thu Dec 9 19:02:25 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-mode-map): fixed FSF call to set-keymap-parent * cc-mode.el (c++-mode-map): JWZ contributed a better way to share keymaps for v18 using nconc (c-populate-map): obsolete, move all define-keys into c-mode-map if statement * cc-mode.el (c-emacs-features): for Emacs 19's, add a flavor member to distinguish between FSF19 and Lucid19. (c++-mode-map): for Emacs 19's, inherit c++-mode-map from c-mode-map. Handle FSF/Lucid properly and handle GNU18 the hard way. Wed Dec 8 22:43:02 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-down-block): changed call of c-beginning-of-block to c-up-block * cc-mode.el: (c-populate-map) (c-populate-syntax-table): new funcs to consolatate setting these structures (c-mode-map) (c++-mode-map): get as close as we can with BOCM's mappings, but there are still some inconsistencies I need to clean up Tue Dec 7 23:52:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-set-style): added functionality (c-macro-expand): added autoload (documentation and docstrings): updated many places (c-set-offset): better interactive spec (c-fill-paragraph): stolen from c-mode, but not looked at yet (cc-mode.el): added fset compatibility with c-mode NOTE: THERE ARE STILL SOME FUNCTIONS I HAVEN'T MOVED HERE YET. Mon Dec 6 15:46:30 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c-guess-basic-semantics): CASE 5D is only a statement-cont if the beginning-of-statement is not bound by continued-sexp * cc-mode.el: fixed a coupble of cc-emacs-features to c-emacs-features Fri Dec 3 23:05:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-mode.el): changed all symbols from cc- to c-, except where both c- and c++- are needed: c++-mode-abbrev-table, c++-mode-map, c++-mode-syntax-table, (c-mode-common-hook): new common hook name (c-mode-map): don't add c-scope-operator. Thu Dec 2 00:59:34 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-guess-basic-semantics): CASE 7B, its possible that the line that placeholder points to does not contain the first streamop. This can be the case if the streamop line follows an `if' clause. Wed Dec 1 23:35:44 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-macroize-region): simplified so begin/end semantics are identical to cc-comment-region. (cc-backslashify-current-line): do not (forward-char -1) if eol == bol. Also, must let-bind kill-lines-magic to nil so that blank line, with only a \ on it will not consume the newline character Mon Nov 29 22:50:30 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-indent-region): only generate an error on non-open paren/brace when shutup-p is nil * cc-mode.el: (cc-uncomment-region) (cc-comment-region): combined into 1 function, bound to C-c C-c and behavior analogous to cc-macroize-region. (cc-up-block) (cc-down-block): new commands, bound to C-c C-u and C-c C-d respectively. * cc-mode.el (cc-indent-exp): don't indent line with cc-indent-via-language-element if line is blank * cc-mode.el (cc-electric-brace): use (boundp 'blink-paren-function) as emacs version test, not cc-emacs-features. The latter breaks on Emacs18's with the syntax patch * cc-mode.el (cc-guess-basic-semantics): fixed the comment-intro regexp to ignore newlines. (spaces and tabs only) Fri Nov 26 19:01:34 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-search-uplist-for-classkey): fixed two small bugs. first, the cdr of foundp should be cc-point boi to catch any template prefix on the class key (remember we're searching backwards now -- maybe we should search forward, eh?). Also, we have to set donep to (not foundp) so that the search ends when we haven't found any classkey * cc-mode.el (cc-guess-basic-semantics): CASE 13.D make sure we're not looking at a globally scoped function call * cc-mode.el (cc-guess-basic-semantics): arglist-close should relpos boi of containing-sexp (cc-change-semantic-symbol-offset): fixed setqcdr typo (cc-offsets-alist): arglist-close default is now + * cc-mode.el (cc-beginning-of-statement): fix problem when crossing a paren level (i.e. the cc-safe forward-sexp call fails). just move back a space and keep going. (cc-guess-basic-semantics): expand CASE 5C test and CASE 5E relpos calculation Wed Nov 24 22:54:31 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-safe): added this macro back in -- it seems to be useful (cc-beginning-of-statement): really improved this a lot. we only go back a sexp if we aren't already at the beginning of indentation. This is now a more generally useful function since it seems to do the right thing under all circumstances. (cc-guess-basic-semantics): lots of changes to use the new cc-b-o-s function. All known indentations after hanging braces are now fixed. This includes case 4D.5, CASE 7, CASE 12, and CASE 13.F. Are there others? * cc-mode.el (cc-offsets-alist): added knr-argdecl offset (cc-change-semantic-symbol-offset): allow addition of new langelem symbols with universal arg (cc-guess-basic-semantics): added recognition of subsequent knr-argdecl langelems in cc-c-mode only * cc-mode.el (cc-electric-brace): in brace-else-brace cleanup, I forgot to insert the new "} else {" string after deleting the old string! * cc-mode.el: (cc-back-block) (cc-safe-uplist) (cc-safe-downlist): obsolete (cc-search-uplist-for-classkey): completely rewritten for speed. it now uses re-search-backwards limited to two bod's back. Orders of magnitude faster when operating towards the end of a large file. In fact exec time is not buffer size dependent anymore (but like everything else, it is bod dependent of course). (cc-guess-basic-semantics): fixed cases 4, 7, and 12 to work with the new cc-search-uplist-for-classkey Tue Nov 23 22:41:41 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-guess-basic-semantics): fixed case 4F. if a class-close is found, it should indent relative to the class declaration, not the opening brace (i.e. the cdr of inclass-p, not the car) * cc-mode.el (cc-guess-basic-semantics): fix CASE 12's determination of the type of langelem that a brace closes. * cc-mode.el (cc-c++-mode-syntax-table): switched A/B comment styles as per Paul Smith's FSFmacs patch (cc-1bit-il): switched A/B comment styles as per Paul Smith's FSFmacs patch * cc-mode.el (cc-search-uplist-for-classkey): only search when in a C++ buffer. C buffers have no enclosing class! * cc-mode.el (cc-electric-pound): oops, forgot to prefix-numeric-value arg on the self-insert-command * cc-mode.el (cc-mark-function): must funcall the second call to push-mark since v18 only accepts 2 arguments, not the 3 of v19. (cc-electric-brace): fix the blink-paren-function/-hook mismatch for v18 vs. v19. (cc-point): added the (,@ nil) form as a workaround for v18's backquote bug. Doesn't seem to hurt us for v19 so I left it in for everyone. Mon Nov 22 23:29:19 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-guess-basic-semantics): CASE 12, always return boi of the line that containing-sexp is on, not just for block-close langelem * cc-mode.el (cc-search-uplist-for-classkey): make backward searching slightly more efficient by stopping when char under search-start is a close brace * cc-mode.el (cc-label-key): new constant, change all concat'd label regexps to use this new constant (cc-guess-basic-semantics): fix case 13.D to not accidentally code a statement that follows a label as a ?: construct * cc-mode.el (cc-indent-command): fixed behavior when cc-tab-always-indent was nil. should now be like old behavior (CASE 1) * cc-mode.el (cc-emacs-features): improve documentation * cc-mode.el (cc-point): retain quoted symbol semantics on argument but don't use dangerous `eval' to get an eq ready symbol * cc-mode.el (cc-indent-exp): better error messages so people don't get as confused * cc-mode.el (cc-beginning-of-statement): much more robust movement across balanced expressions now correctly finds the beginning of statements for very complex forloops and more. We now no longer assume that expressions begin and end on a single line. (cc-guess-basic-semantics): CASE 5C is expanded to correctly locate multi-line mathematical paren groupings. Also, CASE 5E now returns boi at the beginning-of-statement for any arglist-cont. * cc-mode.el: (cc-electric-brace) (cc-electric-slash) (cc-electric-star) (cc-electric-semi&comma) (cc-electric-colon) (cc-change-semantic-symbol-offset): changed docstrings to more accurately describe defuns' behavior * cc-mode.el (cc-indent-exp): calculate bod before doing the forward-sexp since unindented open parens in col0 lower down will mess this calculation up. Sat Nov 20 21:53:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-submit-bug-report): typo on cc-hanging-colons-alist * cc-mode.el: (cc-keep-region-active) (cc-make-region-active): split this into a macro (the former) and a defun (the latter). This way we can check for interactivity as expected, but still cut down on the number of bc warnings. * cc-mode.el: (cc-setup-comment-indent-variable) (cc-keep-region-active): make these defuns so that the .elc file won't be editor version specific. The trade off is that the byte compiler will complain * cc-mode.el (cc-lineup-C-comments): limit re-search-forward to eol, not eol-1... why did we do this? * cc-mode.el: (cc-electric-brace) (cc-electric-semi&comma) (cc-electric-colon): re-indent the line even if cc-auto-newline is nil, just don't add any newlines * cc-mode.el (cc-offsets-alist): multi-line strings should be shoved against the left side margin * cc-mode.el (cc-setup-comment-indent-variable): new macro to cut down on byte compiler warnings * cc-mode.el (cc-case-statement-key): should now recognize character constants as arguments to case statement * cc-mode.el (cc-keep-region-active): support for FSFmacs and don't lay down calls to variables that don't exist (cc-submit-bug-report): variable typos * cc-mode.el: fixed order of macro expansions. defmacro's must appear before their first use -- this is probably why cc-point was busted in compiled code Fri Nov 19 18:44:54 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-guess-basic-semantics): added some minimal recognition of template continuation lines. Probably not so great. (cc-guess-basic-semantics): fixed top-level decl continutation lines (cc-guess-basic-semantics): fixed ?: constructs * cc-mode.el: (cc-c++-mode) (cc-c-mode): setq'ing of comment-start/-end must happen *after* cc-common-init for those values to retain their proper settings (cc-indent-exp): add optional SHUTUP-P argument to suppress operational messages. (c++-indent-exp): removed this commented out function. I think the byte-compiled, simplified cc-indent-exp is fast enough! (cc-indent-region): stolen from c-mode and fixed. (cc-beginning-of-inheritance): backscanning must stop when we're looking at a cc-class-key (cc-guess-basic-semantics): inher-intro and inher-cont should not have inclass langelem added since their relpos offsets already contain any inclass offset Thu Nov 18 23:06:37 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (cc-change-semantic-symbol-offset): new command * cc-mode.el (cc-guess-basic-semantics): added recognition of 'block-open braces following a full statement (yup they are legal) * cc-mode.el (cc-lineup-C-comments): added to support old cc-C-block-comments-indent-p behavior * cc-mode.el: removed the multi-line preprocessor stuff. its just too much of a hack right now * cc-mode.el: some limited support for multi-line macros and such Wed Nov 17 23:29:41 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed all byte-compiler warnings. did a pass through the comments and docstrings. macro-ized a few more defuns * cc-mode.el (cc-indent-exp): a slow, but moderately useful interrim solution. * cc-mode.el (cc-point): another small fix to the macro to get byte compilation to work * cc-mode.el (cc-point): small fix to macro expansion. must eval position so that 'sym idiom still works * cc-mode.el: added cc-keep-region-active to all appropriate interactive defuns * cc-mode.el (cc-point): made this a macro so things should be much quicker when byte compiled * cc-mode.el (cc-electric-brace): insert any after-brace newlines after all cleanups have taken place * cc-mode.el (cc-electric-colon): semantic information can only be accurately retrieved on the line with colon for label, case-label, and access-key. member-init-intro and inher-intro must be gathered from the following line. * cc-mode.el: (cc-electric-start) (cc-electric-slash): use cc-indent-via-language-element instead of cc-indent-line Tue Nov 16 23:04:59 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-electric-colon): deleted * cc-mode.el (cc-electric-brace): inhibit blinking any close paren until we've done all our magic, then just call blink-paren-function manually * cc-mode.el (cc-guess-basic-semantics): CASE 4 was missing a call to cc-backward-syntactic-ws which broke arglist indentations * cc-mode.el (cc-beginning-of-statement): catch multi-line function calls by going backward over balanced () sexps * cc-mode.el: had to add all the lineup functions from c++-syntax.el * cc-mode.el: continued if/while/do/else/for statements now work again * cc-mode.el: 1. a good shot at cc-electric-colon 2. added cc-scope-operator bound onto C-c C-; * cc-mode.el: everything is rewritten and tested except c++-electric-colon and c++-indent-exp Thu Nov 11 21:24:06 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: got rid of glaring byte-compiler reported problems. * cc-mode.el: The bulk of the rename work has been done. The entire mode has been renamed CC-Mode. The file has been renamed cc-mode.el, and all symbols have changed from c++- to cc-. In addition, all known remaining c-mode dependencies have been eliminated. There is still much work to be done. Tue Nov 9 22:26:06 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: rough attempt at syntactic analysis. more to come Mon Nov 1 03:25:12 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-search-uplist-for-classkey): restore point if no enclosing class is found Sun Oct 31 19:14:59 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c++-narrow-out-enclosing-class) (c++-search-uplist-for-classkey): new defuns (c++-point): added 'boe and 'eoe positions Fri Oct 29 22:42:35 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: totally screwed up indentation. we're going to have to back out the last few mods. URG! * cc-mode.el (c++-indent-exp): special case of looking at ?{, should not add c-indent-level since this is only for C statements wrt containing block and not block opening paren * cc-mode.el (c++-calculate-indent): undid split from previous revision. now case 3A always returns 0. Any additional top-level brace offset gets applied in c++-indent-line and c++-indent-exp (although the later does not yet work). * cc-mode.el (c++-calculate-indent): needed to split case 3A into 2 parts since bobp does not get the same indent as a top-level opening paren Wed Oct 27 14:28:16 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-common-init): don't set the auto-hungry state here since the mode hook has not been run yet. (c++-mode) (c++-c-mode): set the auto-hungry state for the buffer after the mode hook has been run Wed Oct 20 18:46:53 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-mode-map): do NOT define C-m and C-j, so as to retain the standard default settings for these keybindings Mon Oct 11 16:32:02 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-calculate-indent): in CASE 3C, when checking for hanging member init colon, but not scope operator, we didin't check for double colons when looking at the preceding-char. Now look at char before point and char 2 before point. If both are colons, we're looking at a scope operator. Fri Oct 1 13:21:00 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-common-init): changed the test for comment-indent-function to checking for boundp of the variable instead of c++-emacs-features since Emacs 18 with syntax patches is (8bit v19) but does not have the variable bound. Wed Sep 29 21:08:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-backward-to-start-of-if): better error message for else with no if * cc-mode.el (c++-calculate-indent): test case 3H, when taking the current-column, must subtract out the inclass-shift so it doesn't get added twice. inclass-shift is implicit in current-column. Tue Sep 28 23:11:04 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-mode-syntax-table): don't be as harsh on FSF * cc-mode.el: (c++-cleanup-list) (c++-hanging-member-init-colon) (c++-auto-hungry-initial-state) (c++-auto-hungry-toggle) (c++-mode): use the terminology "valid" instead of "legal" to define acceptable values as per RMS's conventions. * cc-mode.el (c++-c-mode): improve the docstring re: running the hook * cc-mode.el (c++-indent-exp): use c++-cont-indent to calculate continued statement indentation amount. remove large part of hackery here so lets watch and see if anything got broken, but I think c++-c-i should do the trick for all constructs * cc-mode.el (c++-indent-defun): better, quicker implementation of this defun * cc-mode.el (c++-electric-pound): better implementation of previous patch * cc-mode.el (c++-electric-pound): only align pound to left column if there isn't one already there. This lets people enter ## as cpp concat command * cc-mode.el (c++-electric-semi): renamed c++-electric-semi&comma to implement }, and }; cleanups (c++-cleanup-list): added list-close-comma to allow cleanups of }, constructs. * cc-mode.el: cleaned up some comments * cc-mode.el (c++-common-init): new function to provide one entry point for all common initializations of the mode. (c++-mode) (c++-c-mode): use c++-common-init to do the common stuff, then do mode specific stuff. * cc-mode.el (c++-calculate-indent): complete fix for proper indentation of base classes in a multiple inheritance declaration. (c++-baseclass-key): new constant defining regexp for base class defs * cc-mode.el: partial fix for multi-inher lines Mon Sep 27 19:15:51 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-backward-to-start-of-if): give a more informative message if an unbalanced if/else was found * cc-mode.el (c++-compound-offset): fixed a bug when looking at "typedef enum", this wasn't registering as an enum start. (c++-indent-exp): fixed indentation of comma separated compound statements by using the function c++-compound-offset to calculate offset instead of just using the variable c-continued-statement-offset * cc-mode.el (c++-mode): compatibility with old style comment-indent-hook and new style comment-indent-function * cc-mode.el: (c++-indent-line) (c++-calculate-indent): improved calculate in let-body for open-paren and top-open-paren values, using car-safe and cdr-safe (c++-indent-line): fix typo bug when looking at open brace. (c++-indent-line): apply TOPLEVEL c-brace-offset when brace is at top level wrt class, or real top level. * cc-mode.el (c-brace-offset): moved here from c-mode.el (c++-mode): for vars c-brace-offset and c++-block-close-brace-offset, both can now take list values. describe these in the mode's docstring. (c++-indent-exp) (c++-indent-line) (c++-calculate-indent): when looking at an open brace, apply c-brace-offset depending on top-level-ness of the opening brace. Fri Sep 24 22:05:21 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-indent-exp): when inside a class definition, if we are looking at an open brace, we apply c-continued-brace-offset instead of just zero. this allows users to indent the opening brace of an inline function body. * cc-mode.el (c++-calculate-indent): when inside a class definition, if we are looking at an open brace, we apply c-continued-brace-offset instead of just zero. this allows users to indent the opening brace of an inline function body. * cc-mode.el (c++-calculate-indent): removed the commented out text which used to test for null state. we never hit null state from c++-parse-state anymore. * cc-mode.el (c++-emacs19-accurate-bsws): new function which skips syntactic whitespace w/o treating cpp macros as comments syntactically. (c++-emacs18-bsws): renamed from c++-backwards-syntactic-ws (c++-lemacs-pre19-8-bsws): renamed from c++-backwards-syntactic-ws-1 (c++-emacs18-il): renamed from c++-in-literal (c++-8bit-il): renamed from c++-in-literal-8-bit (c++-1bit-il): renamed from c++-in-literal-1-bit Changed the way compatibility is fset into the function symbols c++-backward-syntactic-ws and c++-in-literal. Tue Aug 10 16:44:26 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: minor cosmetic comment typo Thu Jul 29 00:18:00 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: consensus was to nuke c++-insert-header Mon Jul 12 20:37:27 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-mode.el): updated the comments at the top of the file * cc-mode.el (c++-calculate-indent): removed test for null state during initial parse from beginning-of-defun to indent-point. this is obsolete now. Fri Jul 2 22:42:03 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-mode-map): removed bindings to obsolete functions c++-beginning-of-defun and c++-end-of-defun. (c++-electric-terminator) (c++-in-literal) (c++-in-literal-8-bit) (c++-in-literal-1-bit) (c++-point) (c++-indent-defun): changed all references of obsolete functions c++-beginning-of-defun and c++-end-of-defun to beginning-of-defun and end-of-defun respectively. * cc-mode.el: (c++-match-header-strongly) (c++-defun-header-strong-struct-equivs) (c++-defun-header-strong) (c++-defun-header-weak) (c++-beginning-of-defun) (c++-end-of-defun): removed as obsolete. there are better and cheaper ways of accomplishing the same functionality. * cc-mode.el (c++-electric-brace): I missed a few calls to c++-indent-line. Added bod argument to remaining few. * cc-mode.el (c++-calculate-indent): removed logic dealing with (null state) and placed an error call there in anticipation of removal of header strong matching stuff. I want to be sure there's no way to get to this code (c++-electric-brace): added bod argument to calls to c++-indent-line so the correct bod is found, not the newly created one with the just inserted open brace. * cc-mode.el: (c++-indent-command) (c++-tab-always-indent) (c++-hanging-braces) (c++-mode): changed the not-nil-or-t language to read "other than nil or t" Thu Jul 1 17:40:53 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el (c++-backward-to-start-of-if): changed c++-backward-sexp call to backward-sexp now that parse-sexp-ignore-comments is handled correctly. Wed Jun 30 17:03:00 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c++-forward-sexp) (c++-backward-sexp): removed because these are obsoleted by the correct implementation for setting parse-sexp-ignore-comments. (c++-mode): improved idiom for setting up local vars Mon Jun 28 15:47:13 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: (c++-cleanup-list) (c++-mode) (c++-fast-backward-syntactic-ws-1) (c++-calculate-indent) (c++-in-literal) (c++-in-literal-8-bit) (c++-in-literal-1-bit) (c++-at-top-level-p) (c++-backward-to-start-of-do) (c++-backward-to-start-of-if) (c++-uncomment-region): install RMS's suggested doc string fixes based on last public release. Wed Jun 23 13:58:52 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: hacking on syntax entry must be mode specific in -ws functions. ie in c++-c-mode, hack c++-c-mode-syntax-table and for c++-mode hack only c++-mode-syntax-table. Mon Jun 21 21:40:15 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: should not skip-chars-backward in ws-2, let forward-comment handle that Fri Jun 18 21:31:24 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: another refinement to addition offset given to open brace lines in c++-indent-exp. Check for not at top level wrt class before adding c-indent-level. * cc-mode.el: another fix to c++-indent-exp for member init lists * cc-mode.el: fixed c++-indent-exp when comments follow a continued statement * cc-mode.el: a fix to c++-indent-exp where c-brace-offset is < 0 * cc-mode.el: fixed some comment spelling errors which were fixed (but *not* reported!) by FSF * cc-mode.el: fixed a problem where default_answer("boof: glorp"); was being incorrectly matched to a default: statement Thu Jun 17 21:52:21 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: update language to accurately reflect state of Lemacsen and FSFmacsen Wed Jun 16 22:27:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed indentation when base class declaration is on a separate line then the derived class intro header. * cc-mode.el: 1. cleaned up the way closing block braces are adjusted in c++-indent-line. 2. also extended c++-block-close-brace-offset to allow list value so the following style can be easily supported: foo(a) { if(a) { asasdfsdf; } } Previously, there was no way to adjust the closing brace into column zero. Tue Jun 15 22:04:43 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: use c-continued-statement-offset instead of c-indent-level to indent comma separated arg decl lists * cc-mode.el: bind C-m to newline-and-indent * cc-mode.el: much simplification on c++-fast-backward-syntactic-ws-2 to work with new forward-comment semantics * cc-mode.el: don't skip up past compound statement if we're in a member init list * cc-mode.el: fixed a bug in the translation of CASE 3 to cond stmt * cc-mode.el: 1. cleaned up the spaghetti if's in CASE3 of c++-calculate-indent, by converting all if's to a single cond statement -- I *hope* I got it right! 2. Added indentation, via c-indent-level of multi-line, comma-separated, compound statements/declarations, with correction for enum and static array inits. y Mon Jun 14 21:54:38 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: merged in submitted patch to fix a possible bug which rears its ugly head in FSFmacs19. I haven't verified it so the fix only happens in FSFmacs Thu Jun 3 22:42:44 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: try to conform to GNU cosmetic style Tue Jun 1 14:58:00 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: better to make a copy of the syntax table so we don't screw up text mode's syntax table! Fri May 28 22:20:57 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed the bug in c++-electric-brace where entering an open brace while point is at bol and c++-auto-newline is nil did not indent the brace. Tue May 25 18:37:21 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: some cosmetic differences to c++-emacs-features Mon May 24 23:23:05 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: take out bogus defun c++-emacs-features * cc-mode.el: be really really smart about figuring out c++-emacs-features * cc-mode.el: we must use a different c++-in-literal for GNU19's 1-bit solution Wed May 19 14:19:20 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: better c++-emacs-features deciphering Tue May 18 15:13:39 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: no c++-mode-maintainer Fri May 14 22:05:02 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: can't yet make c++-indent-exp work in weird situation (see bug reports) * cc-mode.el: make sure we check for default: in the same place we check for case: labels in CASE 4 of c++-calculate-indent Tue May 11 21:41:13 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: a little better documentation * cc-mode.el: fixed the compat cond when setting c++-backward-syntactic-ws * cc-mode.el: fixed the string-match call in c++-emacs-features Mon May 10 18:20:42 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: check for forward-comment first * cc-mode.el: fixed syntax errors in previous mod * cc-mode.el: attempt to port between all known flavors of emacsen Thu Apr 22 21:16:15 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: ask user if they want to submit a bug report before actually doing it * cc-mode.el: quick fix for when the ? part of a ?: construct is a negative number Wed Apr 21 19:53:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: use new interface to reporter.el Mon Apr 19 20:41:48 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: uuencode when sending to ftpmail * cc-mode.el: c++-mailer is obsolete now * cc-mode.el: modify c++-submit-bug-report to use reporter package, and require it. * cc-mode.el: updated some documentation about getting c++-mode Fri Apr 16 15:36:39 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: in c++-indent-exp, during the logic which evaluates special adjustments in the line's indentation, the sequential ifs should be a cond statement since the conditions should be mutually exclusive * cc-mode.el: updated mail-server (getting the mode) comments Fri Apr 2 15:35:10 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-backward-to-start-of-if wasn't taking into account "if" clauses in intervening comments. Needed to add a c++-backward-syntactic-ws Thu Apr 1 23:08:37 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: cleaned up (I hope) all docstrings related to auto-hungry features * cc-mode.el: modified c++-class-key to recognize typedef in addition to extern * cc-mode.el: fixed c++-electric-star handling of stars inside C block comments but not part of comment line head (i.e. stars embedded inside C block comment lines not at 'boi, don't re-indent line) Thu Mar 18 18:49:42 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fix infinite loop in c++-fast... in the following situation \n #define x \ -----------^ hit return here * cc-mode.el: wrap temporary binding of # to comment syntax in c++-fast-... in an unwind-protect to ensure that it gets reset on any exit Thu Mar 11 15:36:26 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed indentation of block comments after first /* line in c++-indent-exp Wed Mar 10 18:50:29 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-in-literal-quick wasn't checking for inside a string Fri Mar 5 20:00:17 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed regexps for case labels... I hope Thu Mar 4 23:00:30 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: updated copyright date * cc-mode.el: c++-c-mode uses c-mode-abbrev-table * cc-mode.el: in c++-fast-backward-syntactic-ws, check for lim=(point) 2. extended c++-class-key to include optional "extern" keyword * cc-mode.el: 1. extended c++-class-key to handle template definitions 2. made MI-regexp in c++-calculate-indent into the global constant c++-inher-key so it doesn't need to be concat'd every entry into the loop. * cc-mode.el: fixed small infinite loop introduced in previous patch * cc-mode.el: fixed c++-indent-exp when a multi-line C block comment caused calculation of state to be wrong. Now, when calculating line-end, we first check to see of eol is in a C comment, and if so, we scan forward until we find the end of the block comment. this algorithm might break if there is code on the same line, but after the closing */ of a comment. this is to bizarre to support * cc-mode.el: no longer rely on # being of syntax class comment for really patched emacses, except for convenience when in c++-fast-backward-syntactic-ws. Also, in this method, go into a loop checking for cpp directives since its possible that a directive has a comment on the end of the line: #include /* opening a block comment here * which isn't closed until here */ Finally, fix c++-in-literal-quick to handle new syntax class of # Mon Mar 1 23:32:40 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: no longer rely on # being of syntax class for really patched emacses * cc-mode.el: c++-macroize-region will now take any prefix arg instead of just a negative arg. Tue Feb 16 20:30:37 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: don't use _ as word constituent, instead fix regexps * cc-mode.el: give _ word constituent syntax class so indentation of case_ and like symbols will work properly. forward-word will gobble underscores in symbols so that's the trade off for taking the easy way out. Fri Feb 12 16:40:35 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-backward-to-start-of-if was necessitated because backward-sexp call was bombing out in new syntax, on single quote in preceding C++ comment line. use c++-backward-sexp to properly handle this and change all references of c-backward... to c++-backward. Thu Feb 11 18:33:50 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: should only bind parse-sexp-ignore-comments to t if c++-is-really-fixed-p Sat Feb 6 00:04:45 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: in c++-comment-indent, if previous line contains a comment only line that is to the left of comment-column, indent the line to comment-column Fri Feb 5 23:41:34 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed K&R C arg decl with keyword struct in line * cc-mode.el: fixed c++-indent-command to follow documentation. previous the following situation was broken: c++-tab-always-indent == nil and: ... { foo; ^------- point was here * cc-mode.el: use Ken Laprade's patch for format vs symbol-name print of c++-special-indent-hook * cc-mode.el: check for (not (c++-in-parens-p)) when deciding whether we're looking at a continuation line or not to avoid bad indentation of continued lines such as: if( !tnode->expanded_p() && docobj->hasChild_p() && docobj->tocLevel() < xmaxTocDepth ) * cc-mode.el: fixed anchor of comment only lines in c++-indent-exp * cc-mode.el: anchor comment only lines to (current-column) if the comment is at, or to the right of, comment-column. * cc-mode.el: c++-continued-member-init-offset works for line with just single colon line, where member inits follow on subsequent lines: ff::ff () : xxx (0), yyy (0) { * cc-mode.el: don't add c-continued-statement-offset if looking at a class's opening brace * cc-mode.el: fixed c++-indent-exp wrt stream ops * cc-mode.el: fixed another small problem with nested class indentation * cc-mode.el: another fix for nested class indentation when looking at the line after an access specifier. we needed to substract one level of indentation Tue Feb 2 21:27:52 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: modifications to better indent nested classes Fri Jan 29 22:31:07 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: in c++-forward/backward-sexp, only let bind parse-sexp-ignore-comments to t if emacs is fixed (not really fixed) Wed Jan 27 22:48:56 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: some previous fix (don't know when) broke MI continuation line indentation. This fixes that problem by making sure we're not looking at MI-regexp * cc-mode.el: commented out bogus part * cc-mode.el: commented out bogus top level continuation indentations Mon Jan 25 23:34:52 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed minor bug with c++-submit-bug-report which manifests only on unpatched emacses * cc-mode.el: fixed small bug in c++-submit-bug-report manifesting in unpatched emacses Thu Jan 21 23:38:34 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-indent-exp must let-bind parse-sexp-ignore-comments to t for the whole duration * cc-mode.el: hack for c++-indent-sexp continued statement offsets... are there repercussions??? * cc-mode.el: fixed c++-cont-indent free variable * cc-mode.el: partial fix of continuation lines at top level Wed Jan 20 23:39:40 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: 1. remove infinite loop from c++-in-literal 2. get rid of messages note that c++-in-literal-quick is broken wrt to old emacs patches Wed Jan 13 22:57:51 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-end-of-defun needed to let-bind parse-sexp-ignore-comments to t * cc-mode.el: better c++-in-literal-quick * cc-mode.el: 1. cosmetic cleanups of code 2. a pass through c++-mode docstring and all variables * cc-mode.el: another hack on the comments at the top of the file * cc-mode.el: a documentation pass * cc-mode.el: changed name of c++-backward-over-syntactic-ws to just c++-backward-syntactic-ws to more closely resemble new lemacs builtin function name. * cc-mode.el: fixed c++-syntax-mode-table to work with patched lemacs Sat Jan 9 05:08:25 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: put # back as a comment-style * cc-mode.el: comment about new bc and backward-syntactic-ws * cc-mode.el: better syntax specifications for new patched lemacs Thu Jan 7 22:22:53 1993 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added c++-backward-sexp and c++-forward-sexp which are bound to M-C-f and M-C-b and work better than their non-c++-mode counterparts since they let-bind parse-sexp-ignore-comments to t. Thu Dec 31 22:17:36 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: use the really, really, up-to-date syntax patch for Lemacs 19 Tue Dec 29 01:22:19 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: removed extraneous commented out code * cc-mode.el: need to ensure that c-mode is loaded in * cc-mode.el: fixed a problem inside member init lists, where the first member (on the colon line) has its args continued * cc-mode.el: fix bug when indenting a line at level zero which begins at the beginning of buffer Wed Dec 23 23:20:05 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fix for c++-indent-exp so that it properly indents c block comments Fri Dec 18 16:15:12 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: greater improvements on c++-b-o-w-s performance Thu Dec 17 23:29:18 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: another run at optimizing c++-backward-over-syntactic-ws based on information gleaned from calc.el experience * cc-mode.el: c++-backward-over-syntactic uses beginning-of-defun instead of point-min as minimum distance to scan back Wed Dec 16 21:52:41 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: check for brace insertion at not-quite-end-of-line (ie eol, ignoring any trailing ws) * cc-mode.el: allow c++-backscan-limit to be nil Fri Dec 11 16:26:05 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: in electric terminator, don't just check for eolp to determine if terminator should electrify. also look for hanging whitespace which may look like eolp, even though it isn't: fooo();......\n ^------^ undiscovered ws---| Thu Dec 10 22:59:25 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: simple fix in calculate indent so forward-char 1 at end of buffer won't throw an error Wed Dec 9 17:55:17 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: error in default value for c++-untame-characters. needed to negate the check for c++-emacs-is-fixed-p * cc-mode.el: fixed problems in electric-(star|slash) when inserting as first character in a buffer. * cc-mode.el: don't treat double-colon as member init when member defun is split across two lines at the scope operator. eg: HereIsAReallyLongClassName ::HereIsAReallyLongClassName( const WithALongConstructorArgument& ) : andItsFirstMemberInit( 7 ) {} * cc-mode.el: added some thanks to the documentation Tue Dec 8 23:57:27 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: better c++-submit-bug-report that works with all known mailers Mon Dec 7 16:26:51 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed calculation of multiple member-inits where double colons can appear inside initing parens * cc-mode.el: improved documentation for c++-special-indent-hook Sat Dec 5 02:52:04 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: handled member init lists with first embedded colon foo() : foo, foo, foo, foo, ^--- this should probably be indented to ^--- here (under colon) but that's really hard and of minimal use. * cc-mode.el: finally figured out that "questionable member init" indentation section. It occurs when you have the following style: foo(...) : foo(9), blat(10), clob(3) Note the colon hanging on the previous line. Steve Vinoski is correct, we should not subtract a level of indentation from the shift since inclass-shift takes care of it. * cc-mode.el: seems like a fix for some close parens not getting outdented when c++-paren-as-block-close-p is t. DOES ANYTHING ELSE BREAK???? Fri Dec 4 22:11:27 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed continued expression in a simple if statement where there is a comment between the if and the simple statement. Thu Dec 3 23:38:27 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: cleaned up some documentation * cc-mode.el: fixed c++-indent-exp for stream operators Tue Dec 1 18:01:45 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-backward-over-syntactic-ws should always be given a backlimit in c++-calculate-indent. * cc-mode.el: in previous fix for c++-c-i, it is possible that containing-sexp is nil, so use (goto-char (or containing-sexp bod)) * cc-mode.el: enhancements to c++-calculate-indent so that it doesn't assume that class opening brace starts in column zero. * cc-mode.el: c++-submit-bug-report now reports whether emacs is patched Mon Nov 30 23:39:13 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed K&R C arg decl indentations * cc-mode.el: cosmetic changes * cc-mode.el: removed old c++-bosw which was too slow anyway Fri Nov 27 20:18:12 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed comment indentation for new c++-comment-only-line-offset semantics, and also simplified electric-star and electric-slash. They no longer call c++-electric-terminator. Fri Nov 13 22:42:04 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: some documentation improvements * cc-mode.el: fixed erroneous newline insertion on member init colons when c++-auto-newline is off. * cc-mode.el: fixed buggy regexp which would fail on this situation: int foo( // foo int arg1, // arg1 int arg2 last line gets indented wrong because of the spaces b/w the foo( and the comment * cc-mode.el: 1. alphabetized varlist in c++-dump-state 2. improved portability of c++-submit-bug-report for mailers other than vm. * cc-mode.el: use comment-start-skip instead of hard-coded comment regexp * cc-mode.el: 1. added c++-emacs-is-fixed-p to check for a patched emacs 2. automatically set c++-untame-characters to nil if patched * cc-mode.el: fixed comment-line indent calculation. now c++-calculate-indent does no comment-line calculations, its all handled in c++-indent-line and c++-indent-sexp * cc-mode.el: slight documentation fixup * cc-mode.el: vastly improved c++-comment-only-line-offset to provide ability to determine column-zero offsets * cc-mode.el: attempt to speed up c++-backward-over-syntactic-ws Thu Nov 12 16:45:30 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: 1. some experimental performance enhancements (not working really great) 2. in c++-at-top-level-p, check for null containing-sexp before in-parens Tue Nov 3 20:46:19 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: removed the variable c++-class-member-indent and replaced all occurances with c-indent-level. it caused very bad things when c-indent-level != c++-class-member-indent * cc-mode.el: c++-match-paren must set parse-sexp-ignore-comments to t Fri Oct 2 22:31:14 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: perhaps optimization on skipping backwards over c++ literal comment Tue Sep 29 00:19:22 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: replaced code accidently removed during last bug fix Mon Sep 28 22:44:51 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed default[ \t]*: indentation bug * cc-mode.el: continuation indentation problem should now work correctly. c++-in-function-p search from containing-sexp or point * cc-mode.el: added c++-in-function-p defun to be used when checking if we're in a function. Continuations inside a function * cc-mode.el: fixed the LCD Archive Entry syntax * cc-mode.el: removed c++-fill-C-comment, function is unused anywhere Tue Sep 1 21:02:17 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: 1. compatibility code for loading into a patched emacs 2. also a *slightly* improved c++-backward-over-syntactic-ws. This function needs a drastic overhaul -- I bet its the main performance pig now that emacs is patched. Fri Aug 28 22:07:39 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: final cleansing before posting Thu Aug 27 16:41:30 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added GNU copyright info * cc-mode.el: standard header and many comment changes Wed Aug 26 23:40:46 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: cleaned up documentation * cc-mode.el: yet again, better documentation about untame characters * cc-mode.el: better documentation on c++-untame-characters * cc-mode.el: added some documentation to the front of the file to describe untame characters * cc-mode.el: default value for c++-untame-characters is now just single tick, the most troublesome character Thu Aug 20 19:29:00 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: only check for inside template spec if looking at c++-class-key * cc-mode.el: attempted to address keyword "class" appearing inside a template specification: template Foo& Bar::doit( void ){}; template Foo& Bar::doit( void ){}; Tue Aug 11 14:06:02 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: updated docstring for c++-at-top-level-p Mon Aug 10 22:19:52 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: c++-c-mode's mode-name is "C" * cc-mode.el: style 1-3 is default for c++-C-block-comments-indent-p Thu Aug 6 19:47:36 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed auto-indenting of C block comment style 3 Wed Aug 5 21:25:39 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: another patch to docstring * cc-mode.el: another docstring change * cc-mode.el: qualify doc string change of previous revision * cc-mode.el: improved (hopefully) the docstring for var c++-untame-characters * cc-mode.el: more optimizations by passing bod to c++-at-top-level-p * cc-mode.el: parameterized c++-class-key and c++-access-key the first is class\|struct\|union the second is public\|protected\|private * cc-mode.el: fixed (c++-at-top-level-p t) so it won't get fooled by struct declarations. * cc-mode.el: fixed c++-at-top-level-p so it won't get fooled by struct declarations Tue Aug 4 20:59:29 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed docstring for c++-tab-always-indent Wed Jul 29 14:50:46 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: this branch combines C and C++ modes for inclusion into emacs 19 Tue Jul 28 19:28:29 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed documentation for c++-C-block-comments-indent-p Mon Jul 27 15:13:36 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed indentation of member init list after a multiline member init call Thu Jul 23 19:59:45 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed c++-electric-pound when inserting # at beginning of buffer * cc-mode.el: simple fix for *some* sequence continuation lines Wed Jul 22 13:28:54 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed (c++-at-top-level-p t) so it wouldn't return non-nil if keyword class appears in arglist * cc-mode.el: added to c++-calculate-indent a check if we're at the bobp Tue Jul 21 21:59:27 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: new function c++-calculate-c-indent-within-comment used instead of calculate-c-indent-within-comment (from c-mode). Supports 4 styles of C block comments. Also, new variable c++-C-block-comments-indent-p to control which style(s) to use. * cc-mode.el: fixed c++-indent-exp to handle public/private/protected with friends * cc-mode.el: fixed indentation for the following style: class foo { friend class bar; public: foo(); private: }; Mon Jul 20 20:22:58 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: 1. added c++-paren-as-block-close-p to control whether a closing paren is treated as a closing brace. 2. also added c++-block-close-brace-offset to bug list of variables * cc-mode.el: added a c++-c-mode-syntax-table NOTE: patch in previous version DOES work * cc-mode.el: rewrite of c++-at-top-level-p for c mode (doesn't work) Fri Jul 17 20:14:30 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: change syntax table entry to support lemacs 19 syntax table extension WARNING: this may change Thu Jul 16 19:35:21 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed comment-only lines in c++-indent-exp * cc-mode.el: patch to c++-indent-exp to make it work consistently with manual tabbing * cc-mode.el: better c++-(un)comment-region functions as supplied by enami Wed Jul 15 18:07:13 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: C mode entry point, including a properly working c++-(un)comment-region * cc-mode.el: use c++-backward-over-syntactic-ws in another appropriate location in c++-calculate-indent Tue Jul 14 21:33:04 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: implemented Brian Kennedy's patches for { if style seems to be clean now * cc-mode.el: regexp to correctly pickup '\\' character constant * cc-mode.el: new regexp to match even number of backslashes followed by a quote for c++-in-literal matching of string terminators Mon Jul 13 18:25:21 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: better fix to c++-at-top-level-p for limiting backsearching of class/struct * cc-mode.el: another patch to c++-at-top-level-p, but now slower * cc-mode.el: Igor Metz's patch to fix c++-uncomment-region for Emacs 19 derivatives since zap-to-char now works differently Fri Jul 10 22:02:26 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: in c++-fill-C-comment, its cleaner to use let-bind fill-prefix itself instead of saving its value and later restoring it. * cc-mode.el: c++-at-top-level-p never returns non-nil if inside the parens of an arg decl list for a function. Also cleaned up c++-at-top-level-p's docstring for new functionality * cc-mode.el: 1. added usage notes to top of file 2. another fix for indentation of member init lists in nested classes * cc-mode.el: fixed member init continuation lines * cc-mode.el: fixed emtpy-defun-braces cleanup when at top level wrt enclosing class * cc-mode.el: fixed nested class member init list indentation Thu Jul 9 21:54:08 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added c++-class-member-indent to varlist in bug submission * cc-mode.el: nested classes! added a variable c++-class-member-indent to handle indentation of class members relative to their enclosing class * cc-mode.el: new c++-at-top-level-p function for nested class definitions (does not work though) * cc-mode.el: optimized by changing all references to c++-in-comment-p and c++-in-open-string-p to use memq and c++-in-literal. This should overall reduce the number of calls to c++-in-literal, a time consuming defun. * cc-mode.el: c++-electric-star will now re-indent the line when typed as the first character on a line of a C block style comment continuation * cc-mode.el: fix to c++-at-top-level-p to ignore struct/class declarations inside a defun which are not definitions: void foo() { struct blah; // we are not now (c++-at-top-level-p t) The function is still not perfect so we really need to rethink this algorithm. * cc-mode.el: collapse all c++-point-* commands into a single c++-point command with an argument Wed Jul 8 19:40:14 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed parse-start setq in c++-calculate-indent Tue Jul 7 22:03:41 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: pasing => parsing * cc-mode.el: grammer -> grammar in comment * cc-mode.el: implemented c++-backward-over-syntactic-ws with help of Tor Lillqvist and replaced all occurances of c++-backward-over-cpp-directives and c++-skip-backward-to-noncomment. Mon Jul 6 21:25:17 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: colon and semi-colon are no longer electric inside of literals * cc-mode.el: it is possible that c++-beginning-of-defun with c++-match-header-strong equal to nil will incorrectly find the beginning of defun. if this happens, c++-parse-state will return a null state so we can check for this and then let* bind c++-match-header-strongly to t. Then we re-calculate the beginning of the c++ defun. Seems to work around the (char-after ...) bug * cc-mode.el: swap back to another use of c++-parse-state * cc-mode.el: 1. don't inherit syntax table from c-mode. Initialize completely from in this file 2. wrote c++-parse-state to centralize parsing of syntactic context Tue Jun 30 21:39:23 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed a bug in brace-else-brace cleanup where insertion of new (non-else) brace could possibly go way back to clean up old else brace constructs. * cc-mode.el: use new c++-cleanup-list to replace c++-cleanup-brace-else-brace-p and c++-cleanup-empty-defun-braces-p, and to implement new cleanup on close semi. * cc-mode.el: fixed c++-electric-pound behavior for # directives in a level of nesting for alignleft behavior * cc-mode.el: c++-cleanup-empty-defun-braces-p only for defun braces (not for empty if braces for example) * cc-mode.el: only do the extra c++-indent-line in c++-electric-brace if hanging braces is turned off Wed Jun 24 20:07:00 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added a c++-indent-line in the c++-electric-brace to fix non-hanging brace error message. * cc-mode.el: added function c++-skip-backwards-over-cpp-directives for improved indentation around # lines. Tue Jun 23 19:35:27 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed stream op positioning when first >> or << is on the next continued line of the statement. * cc-mode.el: hacking the mode line should only occur in c++-mode defun, when the mode line is a list, otherwise, if people use the obsolete string-only form, their mode line will be made invalid. * cc-mode.el: fixed indentation of lines not at top level, which follow preprocessor directive lines. Fri Jun 19 21:46:58 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed bug when access specifier line has a comment at the end of it * cc-mode.el: simplified all point-marks to use (point-marker) Thu Jun 18 15:10:04 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed c++-electric-pound by using insert-before-markers * cc-mode.el: 1. added c++-electric-pound command and bound it to # 2. also added c++-electric-pound-behavior to control how # behaves. Currently only supported behavior is alignleft, but eventually I will support nested behavior as well. 3. changed the way c++-electric-delete and c++-insert-command work on # lines. delete is never hungry in the whitespace b/w # and directive, and tab only inserts in this area as well. * cc-mode.el: added c++-delete-function variable and made c++-electric-delete use this variable Wed Jun 17 22:29:12 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added c++-special-indent-hook and bug reporting of this variable * cc-mode.el: support for lining up >> and << * cc-mode.el: added c++-matching-paren as contrib'd by Gnanasekaran Swaminathan Mon Jun 15 21:07:29 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed c++-indent-command when looking at a blank line and c++-tab-always-indent is nil * cc-mode.el: another fix to c++-indent-command for c++-tab-always-indent == nil * cc-mode.el: made c++-indent-command behavior when c++-tab-always-indent is nil consistent with documentation Thu Jun 11 22:44:47 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added a test to see if c++-auto-newline actually inserts the newline doing the auto-fill Wed Jun 10 19:10:31 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed indentation of first member function after an access specifier inside a class definition Tue Jun 9 22:45:24 1992 Barry A.

Warsaw, ITB (warsaw@anthem) * cc-mode.el: complete replacement for c++-in-open-string-p and c++-in-comment-p Tue May 26 22:25:39 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added Warner Losh's addition of c++-relative-offset-p * cc-mode.el: patched c++-backward-to-start-of-do to ignore do/while constructs in comments * cc-mode.el: yet another patch to c++-in-comment-p Fri May 22 18:09:04 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added c++-access-specifier-offset for extra indentation for public, protected, and private keyword lines Thu May 21 19:18:31 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: cosmetic changes Wed May 20 22:53:43 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed typo with c++-always-arglist-indent-p * cc-mode.el: mode-line-format is now not completely overridden, but instead, the c++-isms are tacked onto the format after the mode-name symbol (if it exists). * cc-mode.el: installed Terry Glanfield's patch to c++-indent-exp * cc-mode.el: documented c++-always-arglist-indent, changed the name to c++-always-arglist-indent-p and added to bug report list. * cc-mode.el: installed Milo Chan's patch for addition of c++-always-arglist-indent * cc-mode.el: small patch to fix whitespace only line before top-level construct * cc-mode.el: rewrote c++-tame-comments to look at a list of characters to tame.

Warsaw, ITB (warsaw@anthem) * cc-mode.el: handle comment-only lines which continue from the previous line. Mon May 4 23:33:51 1992 Barry A.

Warsaw, ITB (warsaw@anthem) * cc-mode.el: beginnings of } else { cleanup, but not completely bugless yet * cc-mode.el: fixed indent-c++-exp. when setting this-indent as max of different values, max it with 0 not 1, otherwise some things won't ever end up in column zero. * cc-mode.el: I think I've extended calculate-c++-indent to properly handle switch/case statements (at least the style that I use). Thu Apr 30 22:21:51 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added c++-backward-to-start-of-do, which is analogous to c-backward-to-start-of-if and finds the corresponding preceding do for a do/while statement. made the necessary changes to calculate-c++-indent to handle nested do's * cc-mode.el: this version will now handle continued statements with no compound statements on ifs, elses, fors, dos, and whiles. * cc-mode.el: add tab-width to the list of variables to dump... Wed Apr 29 22:23:25 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: simplification of auto-hungry functions and mode-line updates with much thanks to Hallvard Furuseth. * cc-mode.el: copied c++-in-parens-p from c-mode's c-inside-parens-p. this is so we can play with trying to work around emacs' bogus syntax bugs. we'll see if the new behavior is any better * cc-mode.el: eliminate infinite loop bug in c++-indent-defun by using a marker. this is necessary since c++-indent-line could change the location of the marker and just saving its buffer position is not sufficient. * cc-mode.el: close parens act like close braces by indenting to c-indent-level plus value of c++-block-close-brace-offset. * cc-mode.el: fixed infinite loop problem in c++-indent-defun which was caused by substituting forward-line for next-line. * cc-mode.el: some changes to calculate-c++-indent defun 1. fixed unbalanced paren problem (emacs bug) in comment by adding a paren to the j.peck hack comment (probably should eventually clean up these comments) 2. applied Doug Moore's (dougm@cs.rice.edu) patch to fix continued function declarations of the form: int foo( int i, int j ); ^---- next line should only indent to here 3. cleaned up some comment sections * cc-mode.el: added the variable c++-block-close-brace-offset for modifying the offset of close braces for non-top level blocks (i.e. braces which don't close a function). * cc-mode.el: removed c++-delete-is-hungry-in-literals-p. Delete key is now, *never* hungry inside literals. Tue Apr 28 22:38:35 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed free variable problems in indent-c++-exp 1. innerloop-done was let'ed as inner-loop-done. changed all innerloop-done's to inner-loop-done in body of defun 2. last-depth wasn't let'ed * cc-mode.el: added c++-delete-is-hungry-in-literals-p to control whether hungry-delete consumes whitespace even in literals. * cc-mode.el: whoops, parse-start was a free variable in c++-at-top-level-p. I just added the local binding to the let statement in that defun. * cc-mode.el: changed c++-hanging-braces-p to c++-hanging-braces. this variable can now control whether hanging braces happen always, never, or only on non-top level open braces. * cc-mode.el: fixed comment-only line related bugs: 1. comment-only lines not in the first column, but at the top level were inserting all tab characters. 2. fixed #1, but this caused non-comment top-level lines which follow indented top-level comment-only lines to indent, which they shouldn't do. I think this fixes all repercussions of comment-only lines. * cc-mode.el: replaced all next-line's with forward-line's since next-line is really a user level function (and may be overloaded by the user). Mon Apr 27 16:03:29 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed enum entry bug reported by Rolf Schreiber by patching c++-backward-to-noncomment. it is possible that (max (point-bol) lim) is greater than point, which chokes the search-backward call. I now have a test for sblim being less than or equal to point. Fri Apr 24 22:02:47 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: 1. added documentation in c++-mode for auto-hungry states and related variables. 2. removed duplicated setq's in c++-mode buffer-local-variable setups * cc-mode.el: more header doc information Wed Apr 22 22:30:31 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: final clean up before posting * cc-mode.el: bumping to baseline rev number 2.0 Thu Apr 16 17:05:40 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added LCD Archive Entry and new file header format Wed Apr 15 19:44:38 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed column zero comment-only line indentation problem when inside a containing-sexp. * cc-mode.el: needed to add a trailing newline for proper unsharing Tue Apr 14 18:12:22 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: Bumping * cc-mode.el: added bug reporting information Fri Apr 10 17:48:46 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: cleaned up c++-mode doc string * cc-mode.el: 1. updated mode documentation string for c++-mode to include new variables. 2. changed c++-auto-hungry-toggle-p to c++-auto-hungry-toggle since it is not a binary valued variable. * cc-mode.el: changed ' syntax back to string quote instead of punctuation Thu Apr 9 22:26:00 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added a (goto-char (point-min)) in c++-dump-state * cc-mode.el: added c++-dump-state function for bug reporting Tue Mar 31 23:38:56 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: lots of toggling options, plus individual toggling for hungry-delete-key and auto-newline states. * cc-mode.el: added organization Fri Mar 27 23:19:32 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: major renovation on auto/hungry toggling Thu Mar 26 23:43:09 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: use better mode-line formatting instead of hacking mode-name Fri Mar 20 20:38:29 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: made buffer-local c++-auto-newline and c++-hungry-delete-key-p Thu Mar 19 19:16:14 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: bound c++-toggle-auto-newline function to C-cC-t and compacted info mode name * cc-mode.el: use better mode-line updating than (redraw-display) in c++-toggle-auto-newline Wed Mar 18 19:52:14 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed display of c++-toggle-auto-newline Tue Mar 17 21:01:05 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: test for c++-hungry-delete-key-p (typo) Mon Mar 16 22:14:18 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: added c++-hungry-delete-key-p * cc-mode.el: handles auto newline for member init list * cc-mode.el: replaced within-c++-string w/ c++-in-open-string-p * cc-mode.el: lots of fixes for: 1. column zero comments don't indent 2. made electric chars comment & open-string safe 3. made electric brace w/auto-fill work 4. made calculate-c++-indent work for while( foo ) style 5. added c++-hanging-braces-p for no auto-newline on left braces Sat Mar 14 07:01:14 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: fixed double-colon and various other problems with c-auto-newline also changed c-auto-newline to c++-auto-newline * cc-mode.el: fixed c-auto-newline for double colons and }; syntax * cc-mode.el: fixed autoindent of comments for hanging arithmetic Fri Mar 13 23:47:34 1992 Barry A. Warsaw, ITB (warsaw@anthem) * cc-mode.el: better documentation for electric-c++-slash * cc-mode.el: fixed c++-indent-line to work with electric-c++-slash and bind "/" to it * cc-mode.el: added c++-comment-only-line-offset * cc-mode.el: Initial revision Local Variables: add-log-mailing-address: "bug-cc-mode@gnu.org" End:
