From: Ikumi Keita <ikumi <at> ikumi.que.jp> To: bug-gnu-emacs <at> gnu.org Subject: 28.2; Feature request; facility for dispatch type major mode Date: Wed, 01 Feb 2023 21:28:07 +0900
I'd like to discuss dispatch functions or "superficial" major modes. AUCTeX has the following major mode functions: context-en-mode, context-nl-mode, japanese-latex-mode, japanese-plain-tex-mode They only do language-specific set-ups and turn into context-mode, latex-mode or plain-tex-mode eventually. In some aspects, they are similar with dispatch functions `tex--guess-mode' and `TeX-tex-mode' (AUCTeX) which guess a proper major mode and call it: - They can be specified as `mode' tag of file local variable and entry of `auto-mode-alist'. - They never hold their own `major-mode' value. - When called, they eventually turn into another proper major mode. For these reasons, they can be called "superficial" major modes. Note that it isn't enough to define them like (define-derived-mode japanese-latex-mode latex-mode "LaTeX" ... (setq major-mode 'latex-mode) ...) because it doesn't respond to directory local variable entry of the form ((japanese-latex-mode ...)) in that case. So I hope emacs to have facility to handle such superficial major modes in a clean way.
