How to diff (La)TeX files

How to diff (La)TeX files

[Marcin Borkowski]

Hi all,

when I diff LaTeX files, I get "double font-lock" - both AucTeX's and
diff's.  How would I turn off AUCTeX's font-lock?

Note: I'm not sure whether it's mode-specific, Emacs does not do this in
JS2-mode, but the same happens in Org-mode.  Go figure.

TIA,

(setq TeX-install-font-lock 'ignore)

And then restart the major mode with "M-x latex-mode RET".

Thanks, but I'm afraid you misunderstood me.  I _do_ want font lock in
my AUCTeX buffers.  I don't want it when diffing LaTeX files (since they
become completely unreadable with all the colors then).

Bonus points if I could easily turn TeX font-lock on and off, leaving
the diff font-lock on all the time.

Best,

I think you want to customize `diff-font-lock-syntax`.

Thanks, I found that variable two hours ago;-).  (I didn't expect
a font-lock-related issue to be easily solvable by myself.)
