Subject: bug#70807: Resetting *-local variables before parsing
Date: Mon, 06 May 2024 21:10:05 +0200

Hi all,

please save this small file on your HD and call it 'minimal-test.tex'.

--8<---------------cut here---------------start------------->8---
\documentclass{article}

\begin{document}
text body.
\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

Now set `TeX-parse-self' to t and open the file, hit 'C-c C-n' and the
parsed file 'minimal-test.el' should look like this:

--8<---------------cut here---------------start------------->8---
;; -*- lexical-binding: t; -*-

(TeX-add-style-hook
 "minimal-test"
 (lambda ()
   (TeX-run-style-hooks
    "latex2e"
    "article"
    "art10"))
 :latex)
--8<---------------cut here---------------end--------------->8---

Now move point into preamble and do

   C-c C-m usepackage RET hyperref RET RET C-c C-n

minimal-test.el should look like this now:

--8<---------------cut here---------------start------------->8---
;; -*- lexical-binding: t; -*-

(TeX-add-style-hook
 "minimal-test"
 (lambda ()
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "href")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "hyperimage")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "hyperbaseurl")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "nolinkurl")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "url")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "path")
   (add-to-list 'LaTeX-verbatim-macros-with-delims-local "path")
   (TeX-run-style-hooks
    "latex2e"
    "article"
    "art10"
    "hyperref"))
 :latex)
--8<---------------cut here---------------end--------------->8---

Now comment out the \usepackage{hyperref} and again 'C-c C-n', the
file looks like this:

--8<---------------cut here---------------start------------->8---
;; -*- lexical-binding: t; -*-

(TeX-add-style-hook
 "minimal-test"
 (lambda ()
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "path")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "url")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "nolinkurl")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "hyperbaseurl")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "hyperimage")
   (add-to-list 'LaTeX-verbatim-macros-with-braces-local "href")
   (add-to-list 'LaTeX-verbatim-macros-with-delims-local "path")
   (TeX-run-style-hooks
    "latex2e"
    "article"
    "art10"))
 :latex)
--8<---------------cut here---------------end--------------->8---

Note how the entry for "hyperref" is gone, but not the add-to-list
forms; the value of LaTeX-verbatim-* are not reset.  This probably
applies for `LaTeX-verbatim-environments-local', but I didn't check.

For me, the value of the -local version should be reset somewhere before
parsing and running the style hooks again, but I couldn't find an
appropriate place.  Does this approach make sense?  And if yes, any idea
where to put the reset?  Any comments welcome.

Best, Arash
