The command uses treesit.el when available, otherwise falls back to using syntax-ppss and regexps. Treesit.el needs a new variable that is intended to be set by the major modes so that this and other future functions can know what kind of node we are looking at. * doc/emacs/programs.texi: Mention the new command. * etc/NEWS: Mention the new command. * lisp/progmodes/c-ts-mode.el (c++-ts-mode): Add regexp for the new variable. * lisp/progmodes/csharp-mode.el (csharp-ts-mode): Add regexp for the new variable. * lisp/progmodes/java-ts-mode.el (java-ts-mode): Add regexp for the new variable. * lisp/progmodes/js.el (js-ts-mode): Add regexp for the new variable. * list/progmodes/prog-mode.el (prog-mode-map): Bind the new command by default. (prog-fill-reindent-defun): New command. * lisp/progmodes/sh-script.el (bash-ts-mode): Add regexp for the new variable. * lisp/progmodes/typescript-ts-mode.el (typescript-ts-base-mode): Add regexp for the new variable. * lisp/treesit.el (treesit-text-type-regexp): New variable. --- doc/emacs/programs.texi | 8 +++++++ etc/NEWS | 7 ++++++ lisp/progmodes/c-ts-mode.el | 4 ++++ lisp/progmodes/csharp-mode.el | 5 ++++ lisp/progmodes/java-ts-mode.el | 5 ++++ lisp/progmodes/js.el | 5 ++++ lisp/progmodes/prog-mode.el | 35 ++++++++++++++++++++++++++-- lisp/progmodes/sh-script.el | 4 ++++ lisp/progmodes/typescript-ts-mode.el | 4 ++++ lisp/treesit.el | 9 +++++++ 10 files changed, 84 insertions(+), 2 deletions(-) diff --git a/doc/emacs/programs.texi b/doc/emacs/programs.texi index ba8475e86a..cc06a003e2 100644 --- a/doc/emacs/programs.texi +++ b/doc/emacs/programs.texi @@ -409,6 +409,14 @@ Multi-line Indent @table @kbd @item C-M-q Reindent all the lines within one parenthetical grouping. +@item M-q +Major modes that derive from @code{prog-mode} can reindent all the +lines within a defun around point using +@code{prog-mode-fill-reindent-defun}.
