Hi,
AUCTeX 14.x changed major-mode names from latex-mode to LaTeX-mode. As
indicated in the relevant changes file, the local variables added by
AUCTeX at the bottom of a file are now
%%% Local Variables:
%%% mode: LaTeX <-- not `latex'
%%% End:
However, it seems like this is not enough. It might be that a minor mode
calls hack-local-variables after AUCTeX is loaded; what will happen then
is that the regular latex-mode is activated, and AUCTeX vanishes!
The reason for that is that hack-local-variables eventually calls
hack-one-local-variable, which features this piece of code:
(defun hack-one-local-variable (var val)
"...DOCSTRING..."
(pcase var
('mode ; vvvvvvvv
(let ((mode (intern (concat (downcase (symbol-name val))
"-mode"))))
(unless (eq (indirect-function mode)
(indirect-function major-mode))
(funcall mode))))
…))
In other words, LaTeX-mode gets turned into latex-mode anyways.
Curiously, executing this does indeed drop one down into the built in
latex-mode—it seems that the settings in major-mode-remap-alist are
ignored somehow.
This is not a theoretical issue, and has happened with a particular
minor mode (that issue was fixed, but I reckon there are potentially
more modes out there that do something like this).
I'm not sure there to report this (Is this an Emacs bug with repect to
major-mode-remap-alist not being respected? or hack-one-local-variable
just downcasing the mode?) so I will try here first.
Thanks!
Tony
