Re: font-lock with functions

[wael-zwaiter]

The following works well, but I am concerned that "my-font-lock"
is a bit of a hack and could do with improvement

(defconst my-font-lock
  (append
      nil
      '( (my-match
          (1 (my-bigfont (match-beginning 0)) append))) )
  "Description.")

(defun bigfont-enable ()
  "Enables a typeface for displaying tex commands."
  (setq supinf-signal t)
  (font-lock-add-keywords nil my-font-lock t))

(add-hook 'my-mode-hook #'bigfont-enable)
