写代码时,经常会在注释中注明一些有待未来完成的事项.例如
┌────
│ # REFACTOR: Decouple and clean up this crap.
│
│ # crappy code omitted
└────
正常情况下,除非使用了类似[fic-mode]这样的mode,否则Emacs不会去高亮注释中
的REFACTOR这类关键字.
有一个简单的办法可以做到这一点:
┌────
│ (defun font-lock-comment-annotations ()
│ "Highlight a bunch of well known comment annotations.
│
│ This functions should be added to the hooks of major modes for programming."
│ (font-lock-add-keywords
│ nil '(("\\<\\(FIX\\(ME\\)?\\|TODO\\|OPTIMIZE\\|HACK\\|REFACTOR\\):"
│ 1 font-lock-warning-face t))))
│
│ (add-hook 'prog-mode-hook 'font-lock-comment-annotations)
└────
当然,这种方法并不完美,它会高亮这个代码中的关键字,而不仅仅是注释中的.
