Hi,
I've just upgraded to 13.1.3 from ELPA. I'm on Emacs 27.1.
When I open a LaTeX file, it opens in something called Fundamental mode. But I
do actually get font-locking and the basic AUCTeX menus, but none of my
customizations seem to have loaded. C-c C-c asks for the master file, even
though TeX-master is set in the file-local variables. M-x describe-mode tells
me:
Fundamental mode defined in `tex-mode.el':
This function has :override advice: `TeX-latex-mode'.
I use use-package to load AUCTeX:
(use-package tex
:ensure auctex
:defer t
:mode ("\\.tex\\'" . LaTeX-mode)
[...]
When I try to change the mode of the file by M-x LaTeX-mode, I get an error:
Cannot open load file: No such file or directory, tex-buf
My setup has worked without any problems before the upgrade. It seems
use-package does not load AUCTeX properly, although this is the way recommended
in the manual. I should also say I have a cryptic comment in my init file:
:ensure auctex ;FIXME: cannot be installed automatically
But I can't remember what problem I was trying to fix.
Does anyone who uses use-package have any advice on how to get AUCTeX working
again?
All the best,
Greg
