changeset: 4435:1e2fc51563a598c293a47edbd50b1ff58caa308f tag: tip user: Didier Verna <didier(a)xemacs.org&gt; date: Wed Mar 05 18:01:37 2008 +0100 files: lisp/ChangeLog lisp/newcomment.el description: Fix auto-formatting of comments in auto-fill-mode This patch makes auto-fill-mode properly format comments (when lines are automatically broken). It looks strangely similar to that of: | 1999-06-24 Bob Weiner <weiner(a)beopen.com&gt; | | * simple.el (indent-new-comment-line): Locally bound | `block-comment-start' to `comstart' or else when this is called | from do-auto-fill, e.g. in Lisp mode, it will insert any non-nil | `block-comment-start' value, ignoring any existing spacing after a | comment prefix in the previous line and producing ugly comments. diff -r 7f3d065a56a176d7567899561d6cb5df5a251e41 -r 1e2fc51563a598c293a47edbd50b1ff58caa308f lisp/ChangeLog --- a/lisp/ChangeLog Wed Mar 05 10:41:54 2008 +0100 +++ b/lisp/ChangeLog Wed Mar 05 18:01:37 2008 +0100 ＠＠ -1,3 +1,12 ＠＠ 2008-03-05 Didier Verna <didier＠xemacs +2008-03-05 Didier Verna <didier(a)xemacs.org&gt; + + Fix auto-formatting of comments in auto-fill-mode. + + * newcomment.el (comment-indent): Don't insert a space at bol. + * newcomment.el (comment-indent-new-line): Bind + block-comment-start to comment-start in order to preserve the + formatting of previous comment lines. + 2008-03-05 Didier Verna <didier(a)xemacs.org&gt; Ease customization of face(s) under point. diff -r 7f3d065a56a176d7567899561d6cb5df5a251e41 -r 1e2fc51563a598c293a47edbd50b1ff58caa308f lisp/newcomment.el --- a/lisp/newcomment.el Wed Mar 05 10:41:54 2008 +0100 +++ b/lisp/newcomment.el Wed Mar 05 18:01:37 2008 +0100 ＠＠ -240,7 +240,7 ＠＠ This is obsolete because you might as we (substring comment-start 1))) ;; Hasn't been necessary yet. ;; (unless (string-match comment-start-skip comment-continue) - ;; (kill-local-variable 'comment-continue)) + ;; (kill-local-variable 'comment-continue)) ) ;; comment-skip regexps (unless (and comment-start-skip ＠＠ -443,12 +443,12 ＠＠ Point is assumed to be just at the end o ; (save-excursion ; (beginning-of-line) ; (let ((eol (save-excursion (end-of-line) (point)))) -; (and comment-start-skip -; (re-search-forward comment-start-skip eol t) -; (setq eol (match-beginning 0))) -; (goto-char eol) -; (skip-chars-backward " \t") -; (max comment-column (1+ (current-column)))))) +; (and comment-start-skip +; (re-search-forward comment-start-skip eol t) +; (setq eol (match-beginning 0))) +; (goto-char eol) +; (skip-chars-backward " \t") +; (max comment-column (1+ (current-column)))))) ; "Function to compute desired indentation for a comment. ; This function is called with no args with point at the beginning of ; the comment's starting delimiter.") ＠＠ -498,7 +498,8 ＠＠ Comments starting in column 0 are not mo (setq begpos (point)) ;; Ensure there's a space before the comment for things ;; like sh where it matters (as well as being neater). - (unless (eq ?\ (char-syntax (char-before))) + ;; ... but unless we're at the beginning of a line -- dvl + (unless (or (bolp) (eq ?\ (char-syntax (char-before)))) (insert ?\ )) (insert starter) (setq cpos (point-marker)) ＠＠ -516,8 +517,8 ＠＠ Comments starting in column 0 are not mo (+ (current-column) (- (or comment-fill-column fill-column) (save-excursion (end-of-line) (current-column))))))) - ;; XEmacs change: Preserve indentation of comments starting in - ;; column 0, as documented. + ;; XEmacs change: Preserve indentation of comments starting in + ;; column 0, as documented.
