Hi Arash, I noticed that emacs 27.1 fails with the current AUCTeX master. When I open circ.tex with emacs 27.1, it signals error with "(wrong-type-argument number-or-marker-p nil)" in `TeX-auto-parse'. The local values of `TeX-auto-parse-length' and `TeX-auto-x-parse-length' are both nil in the circ.tex buffer.
It seems that it is due to introduction of :local keyword in defcustom: ,---- | 77a02f837a0d32e2f7b47764d6e7f64ad76001ba | Author: Arash Esbati <ar...@gnu.org> | AuthorDate: Thu Jan 18 22:55:12 2024 +0100 | Commit: Arash Esbati <ar...@gnu.org> | CommitDate: Thu Jan 18 22:55:12 2024 +0100 | | Mark options as buffer-local with the :local keyword `---- As far as I can see, it is a bug of emacs 27.1. The function `custom-declare-variable', which is the essential part of `defcustom', puts the `make-variable-buffer-local' declaration _before_ the actual `defvar', thus ending up with inconsistent local values. Hence we have to refrain from using :local in `defcustom' until we drop support for emacs 27 :-( Regards, Ikumi Keita #StandWithUkraine #StopWarInUkraine #Gaza #StopMassiveKilling #CeasefireNOW
