Emacs mode: how to specify that thing in square brackets should be colored

I write a simple emacs mode. How do I explicitly specify that all things in e.g. square brackets should be colored. Must be smth like that:

( (if thing is in square brackets) . font-lock-string-face)
Solution

  • I assume you're writing a major mode, but font-lock-add-keywords works also in minor modes. Check out its documentation with C-h f RET font-lock-add-keywords.

    (define-derived-mode my-mode text-mode "mymode"
  ;; some init code
  (font-lock-add-keywords nil '(("\\[\\(.*\\)\\]"
                                 1 font-lock-warning-face prepend)))
  ;; some more init code
)
