How can I write emacs lisp code for adding new highlighting pattern?

I found that font-lock-add-keywords is the key but I cannot find how to add a pattern. For example, in clojure;

(defn a-function-name [argument vector]
  ...)

a-function-name is highlighted becuase it's after defn and before [argument vector]. How can I write a rule for this?

(font-lock-add-keywords 'lisp-mode XXXXX)

I cannot write XXXXX part for myself.

=======================

Thank you to all of you :-) Yes, I can find clue in docs and clojure-mode.el as of you said.

Here is what I do and it works well (at least for me)

(font-lock-add-keywords
 'lisp-mode
 '(("(\\(@defn\\)\\>[ \r\t\n]*\\(\\sw+\\)+\\>?"
    (2 'font-lock-function-name-face))))

Why I need this is that I define some macros and emacs does not highlight them properly.

Solution

  • To add to what @juanleon said: See the Elisp manual, node Search-Based Fontification for information about font-lock-keywords. That will help you "write the XXXXX part for yourself."

    Then, as @juanleon said, try something and ask for more help here if it doesn't work. Code tried gets help.
