Thanks for taking the trouble to report this. The following patch should fix this bug. After applying the patch (in .../emacs-24.5/lisp), byte-compile the file with: $ emacs -Q -batch -f batch-byte-compile newcomment.el on the command line. If you then load the file (with M-x load-file) it should then work. However, the complication is that newcomment.el is a built-in part of Emacs rather than being a file loaded at runtime. So you then have the choice of either putting "(load newcomment.elc)" into your .emacs, or rebuilding Emacs entirely (which isn't that time-consuming or difficult). To do this, in directory .../emacs-24.5, do: $ make . If there are still problems with the fix, please report these to the bug mailing list at 22369@debbugs.gnu.org. > For better comprehension check out this > http://stackoverflow.com/questions/34710840/c-comment-in-emacs-linux-kernel-style-v2 > May I suggest the addition of a new comment-style option that does like this? > /* void main() > * { > * int i; > * int b; > * printf("format string"); > * } > */ OK, because of this feature request, I'll leave the bug open.

I don't think there was any more discussion about this. To be exact, the feature request was to have another option for comment-style called something like bottom-extra which would add an extra comment line at the bottom of a group, but not one at the top. Four years on, I'm not convinced the feature is worth implementing, even if it wouldn't be difficult. It would involve extending the spec of comment-styles such that each entry would have EXTRA-TOP and EXTRA-BOTTOM in place of the current EXTRA. Backward compatibility could be had at the cost of counting the number of elements in each entry. One quirk the OP, Geyslan, pointed out was a possibly obtrusive space when an empty line gets commented in comment-style extra-line, something like: /* * foo(); * <=========== possibly obtrusive space. * bar(); */ I'm not sure whether or not this is a bug or a feature. If a bug, it wouldn't be difficult to fix.

This was a year ago, and there weren't any further input here, so I'm guessing we're going with "it's a feature", and I'm therefore closing this bug report.

This space isn't needed by c-indent-new-comment-line (M-j), so I think that it could be an issue too, since it's deliberately doing that. > > Bug report left open, due to a feature request in it. > > -- > Alan Mackenzie (Nuremberg, Germany). > > > In article <mailman.2326.1452736388.843.bug-gnu-emacs@gnu.org> you wrote: >> (setq c-basic-offset 8 >> tab-width 8 >> indent-tabs-mode t >> comment-style 'extra-line) >> (c-set-style "linux") > >> Using the above settings the comment-dwim (with region active) indent >> the second and last lines with spaces instead of tabs. > >> /* >> * void main() >> * { >> * int i; >> * int b; >> * printf("format string"); >> * } >> */ > >> For better comprehension check out this >> http://stackoverflow.com/questions/34710840/c-comment-in-emacs-linux-kernel-style-v2 > >> May I suggest the addition of a new comment-style option that does like this? > >> /* void main() >> * { >> * int i; >> * int b; >> * printf("format string"); >> * } >> */ > > > >> In GNU Emacs 24.5.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.16.6) >> of 2015-09-09 on foutrelis >> Windowing system distributor `The X.Org Foundation', version 11.0.11800000 >> System Description: Arch Linux > >> Configured using: >> `configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/lib >> --localstatedir=/var --with-x-toolkit=gtk3 --with-xft >> 'CFLAGS=-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong >> --param=ssp-buffer-size=4' CPPFLAGS=-D_FORTIFY_SOURCE=2 >> LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro' > >> Important settings: >> value of $LC_CTYPE: pt_BR.UTF-8 >> value of $LC_MONETARY: pt_BR.UTF-8 >> value of $LC_NUMERIC: pt_BR.UTF-8 >> value of $LC_TIME: pt_BR.UTF-8 >> value of $LANG: en_US.UTF-8 >> value of $XMODIFIERS: @im=ibus >> locale-coding-system: utf-8-unix > >> Major mode: Emacs-Lisp > >> Minor modes in effect: >> tooltip-mode: t >> electric-indent-mode: t >> mouse-wheel-mode: t >> tool-bar-mode: t >> menu-bar-mode: t >> file-name-shadow-mode: t >> global-font-lock-mode: t >> font-lock-mode: t >> blink-cursor-mode: t >> auto-composition-mode: t >> auto-encryption-mode: t >> auto-compression-mode: t >> line-number-mode: t >> transient-mark-mode: t > >> Recent messages: > > >> Load-path shadows: >> /home/geyslan/.emacs.d/elpa/helm-20151106.2158/helm-multi-match hides >> /home/geyslan/.emacs.d/elpa/helm-core-20151104.0/helm-multi-match > >> Features: >> (shadow sort gnus-util mail-extr emacsbug message idna format-spec >> rfc822 mml mml-sec mm-decode mm-bodies mm-encode mail-parse rfc2231 >> mailabbrev gmm-utils mailheader sendmail rfc2047 rfc2045 ietf-drums >> mm-util mail-prsvr mail-utils jka-compr find-func help-fns sregex >> re-builder debug tabify cc-langs cc-mode cc-fonts cc-guess cc-menus >> cc-cmds cc-styles cc-align cc-engine cc-vars cc-defs help-mode >> go-mode-autoloads info easymenu package epg-config edmacro kmacro >> cl-loaddefs cl-lib time-date tooltip electric uniquify ediff-hook >> vc-hooks lisp-float-type mwheel x-win x-dnd tool-bar dnd fontset image >> regexp-opt fringe tabulated-list newcomment lisp-mode prog-mode register >> page menu-bar rfn-eshadow timer select scroll-bar mouse jit-lock >> font-lock syntax facemenu font-core frame cham georgian utf-8-lang >> misc-lang vietnamese tibetan thai tai-viet lao korean japanese hebrew >> greek romanian slovak czech european ethiopic indian cyrillic chinese >> case-table epa-hook jka-cmpr-hook help simple abbrev minibuffer nadvice >> loaddefs button faces cus-face macroexp files text-properties overlay >> sha1 md5 base64 format env code-pages mule custom widget >> hashtable-print-readable backquote make-network-process dbusbind >> gfilenotify dynamic-setting system-font-setting font-render-setting >> move-toolbar gtk x-toolkit x multi-tty emacs) > >> Memory information: >> ((conses 16 132515 7051) >> (symbols 48 21866 0) >> (miscs 40 226 747) >> (strings 32 23818 4361) >> (string-bytes 1 883190) >> (vectors 16 12839) >> (vector-slots 8 428611 6669) >> (floats 8 75 442) >> (intervals 56 799 191) >> (buffers 960 17) >> (heap 1024 45432 1517)) > > > -- Regards, Geyslan G.

I managed it for my C style (/*, * and */) using (save-excursion ;; Cleaning only trailing spaces inserted by comment-region. ;; Existing ones are not touched. (replace-regexp "\\(/+\\|^\\s-+\\)\\(\\*\\)\\(\\s-+$\\)" "\\1\\2" nil beg end)) Maybe an optional parameter (trim-trailing-spaces) would be a good call for comment-region function. > >> This space isn't needed by >> c-indent-new-comment-line (M-j), so I think that it could be an issue >> too, since it's deliberately doing that. >> >> > >> > Bug report left open, due to a feature request in it. >> > >> > -- >> > Alan Mackenzie (Nuremberg, Germany). >> > >> > >> > In article <mailman.2326.1452736388.843.bug-gnu-emacs@gnu.org> you >> > wrote: >> >> (setq c-basic-offset 8 >> >> tab-width 8 >> >> indent-tabs-mode t >> >> comment-style 'extra-line) >> >> (c-set-style "linux") >> > >> >> Using the above settings the comment-dwim (with region active) indent >> >> the second and last lines with spaces instead of tabs. >> > >> >> /* >> >> * void main() >> >> * { >> >> * int i; >> >> * int b; >> >> * printf("format string"); >> >> * } >> >> */ >> > >> >> For better comprehension check out this >> >> >> >> http://stackoverflow.com/questions/34710840/c-comment-in-emacs-linux-kernel-style-v2 >> > >> >> May I suggest the addition of a new comment-style option that does like >> >> this? >> > >> >> /* void main() >> >> * { >> >> * int i; >> >> * int b; >> >> * printf("format string"); >> >> * } >> >> */ >> > >> > >> > >> >> In GNU Emacs 24.5.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.16.6) >> >> of 2015-09-09 on foutrelis >> >> Windowing system distributor `The X.Org Foundation', version >> >> 11.0.11800000 >> >> System Description: Arch Linux >> > >> >> Configured using: >> >> `configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/lib >> >> --localstatedir=/var --with-x-toolkit=gtk3 --with-xft >> >> 'CFLAGS=-march=x86-64 -mtune=generic -O2 -pipe >> >> -fstack-protector-strong >> >> --param=ssp-buffer-size=4' CPPFLAGS=-D_FORTIFY_SOURCE=2 >> >> LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro' >> > >> >> Important settings: >> >> value of $LC_CTYPE: pt_BR.UTF-8 >> >> value of $LC_MONETARY: pt_BR.UTF-8 >> >> value of $LC_NUMERIC: pt_BR.UTF-8 >> >> value of $LC_TIME: pt_BR.UTF-8 >> >> value of $LANG: en_US.UTF-8 >> >> value of $XMODIFIERS: @im=ibus >> >> locale-coding-system: utf-8-unix >> > >> >> Major mode: Emacs-Lisp >> > >> >> Minor modes in effect: >> >> tooltip-mode: t >> >> electric-indent-mode: t >> >> mouse-wheel-mode: t >> >> tool-bar-mode: t >> >> menu-bar-mode: t >> >> file-name-shadow-mode: t >> >> global-font-lock-mode: t >> >> font-lock-mode: t >> >> blink-cursor-mode: t >> >> auto-composition-mode: t >> >> auto-encryption-mode: t >> >> auto-compression-mode: t >> >> line-number-mode: t >> >> transient-mark-mode: t >> > >> >> Recent messages: >> > >> > >> >> Load-path shadows: >> >> /home/geyslan/.emacs.d/elpa/helm-20151106.2158/helm-multi-match hides >> >> /home/geyslan/.emacs.d/elpa/helm-core-20151104.0/helm-multi-match >> > >> >> Features: >> >> (shadow sort gnus-util mail-extr emacsbug message idna format-spec >> >> rfc822 mml mml-sec mm-decode mm-bodies mm-encode mail-parse rfc2231 >> >> mailabbrev gmm-utils mailheader sendmail rfc2047 rfc2045 ietf-drums >> >> mm-util mail-prsvr mail-utils jka-compr find-func help-fns sregex >> >> re-builder debug tabify cc-langs cc-mode cc-fonts cc-guess cc-menus >> >> cc-cmds cc-styles cc-align cc-engine cc-vars cc-defs help-mode >> >> go-mode-autoloads info easymenu package epg-config edmacro kmacro >> >> cl-loaddefs cl-lib time-date tooltip electric uniquify ediff-hook >> >> vc-hooks lisp-float-type mwheel x-win x-dnd tool-bar dnd fontset image >> >> regexp-opt fringe tabulated-list newcomment lisp-mode prog-mode >> >> register >> >> page menu-bar rfn-eshadow timer select scroll-bar mouse jit-lock >> >> font-lock syntax facemenu font-core frame cham georgian utf-8-lang >> >> misc-lang vietnamese tibetan thai tai-viet lao korean japanese hebrew >> >> greek romanian slovak czech european ethiopic indian cyrillic chinese >> >> case-table epa-hook jka-cmpr-hook help simple abbrev minibuffer nadvice >> >> loaddefs button faces cus-face macroexp files text-properties overlay >> >> sha1 md5 base64 format env code-pages mule custom widget >> >> hashtable-print-readable backquote make-network-process dbusbind >> >> gfilenotify dynamic-setting system-font-setting font-render-setting >> >> move-toolbar gtk x-toolkit x multi-tty emacs) >> > >> >> Memory information: >> >> ((conses 16 132515 7051) >> >> (symbols 48 21866 0) >> >> (miscs 40 226 747) >> >> (strings 32 23818 4361) >> >> (string-bytes 1 883190) >> >> (vectors 16 12839) >> >> (vector-slots 8 428611 6669) >> >> (floats 8 75 442) >> >> (intervals 56 799 191) >> >> (buffers 960 17) >> >> (heap 1024 45432 1517)) >> > >> > >> > >> >> >> >> -- >> Regards, >> >> Geyslan G.
