My actual scenario involves using latex-mode-hook to load some libraries that require json-mode.
I replicated my issue in a MWE:
I have a LaTeX file:
\documentclass{article}
\usepackage{mwe}
\begin{document}
\blindtext
\noindent
\includegraphics[width=.4\textwidth]{example-image-a}\hfill
\includegraphics[width=.4\textwidth]{example-image-b}
\blindtext
\end{document}
If I load it like this:
emacs -Q test.tex
I get this "correct" latex-mode fontification:
I have also a config file (I simplified it to obtain the feature):
(add-hook 'latex-mode-hook
#'(lambda ()
(package-initialize)
(require 'json-mode)))
If I load my .tex file like this:
emacs -Q --eval "(load-file \"/tmp/config.el\")" test.tex
I lose latex-mode fontification:
- In the last case, to restore correct
latex-modefontification I need to doM-x latex-mode - This problem does not happen with other packages or custom libraries but, in my experience, it happens only for the
json-modepackage. - If I load
json-mode"before"latex-modeI have no problem. E.g. if I modify theconfig.elfile this way:
(package-initialize)
(require 'json-mode)
and I do:
emacs -Q --eval "(load-file \"/tmp/config.el\")" test.tex
I get the correct latex-mode fontification.
Am I doing something wrong or is it some kind of bug in json-mode or in Emacs?
Important note. This didn't happen with previous versions of Emacs. Before upgrading to version 29.2, I was using version 27 and never encountered this issue prior to the upgrade.
