I like to use highlighting when working with emacs. But I don't like some of the default settings. I recently installed emacs 24.4 on my iMac. I really don't like all the highlighting of math expressions such as
$5$
I used to do something like
(fset 'tex-font-lock-syntactice-face-function 'ignore)
or
(fset 'tex-math-face 'ignore)
but that no longer works.
How can I disable highlight for math expressions but keep most everything else?
You can change the highlighting using set-face-foreground (or more generally set-face-attribute. $..$ seems to be highlighted with font-latex-math-face, so to set the foreground to whatever the default is we can use (set-face-foreground 'font-latex-math-face nil). It's still "highlighted" but it will look identical to the surrounding text.
In the following I assume that you are using auctex.
Remove the syntax descriptor for ?$ from font-latex-syntax-alist after loading "font-latex" to avoid fontification of inline formulas delimited by $.
(eval-when '(compile)
(require 'cl))
(eval-after-load "font-latex"
'(setq font-latex-syntax-alist (cl-delete-if (lambda (pair) (eq (car pair) ?$)) font-latex-syntax-alist)))
tex-mode.eland I commented out(,(concat "\\$\\$?\\(?:[^$\\{}]\\|\\\\.\\|{" (funcall inbraces-re (concat "{" (funcall inbraces-re "{[^}]*}") "*}")) "*}\\)+\\$?\\$") (0 tex-math-face))in my own personal custom version because I don't use math. If you don't want to comment out the source, then you might be interested in coping the current setting oftex-font-lock-keywords-1, and commenting out that section and setting the new portion -- e.g.,(setq tex-font-lock-keywords-1 [EVERYTHING EXCEPT WHAT SHOULD BE STRICKEN])If you are using AUCTeX, I don't know.tex-mode.elMost people treat the source code as sacred and use things like(setq . . .instead of touching the source. I like to create my own libraries for things I use every day (like writing documents for business, etc.), starting by copying the source code, and then I modify the daylights out of the source.C-h mand see whether the mode is defined intex-site(AUCTeX) ortex-mode(basic).) Do you want to turn off highlighting just for$…$or for everything such as math environments?
