when I use "use-package" macro in emacs lisp, I found that the argument is highlighted.
but argument of my own macro is not highlighted by emacs.
How to write a macro with highlighted arguments?
use-package
uses font-lock-add-keywords
to mark the argument with font-lock-constant-face
. Replacing "use-package" with "test_macro" in the the code would colorize your argument similarly
(defconst my-font-lock-keywords
'(("(\\(test_macro\\)\\_>[ \t']*\\(\\(?:\\sw\\|\\s_\\)+\\)?"
(1 font-lock-keyword-face)
(2 font-lock-constant-face nil t))))
(font-lock-add-keywords 'emacs-lisp-mode my-font-lock-keywords)
