27 ;; Font-lock-mode is a minor mode that causes your comments to be
28 ;; displayed in one face, strings in another, reserved words in another,
29 ;; documentation strings in another, and so on.
31 ;; Comments will be displayed in `font-lock-comment-face'.
32 ;; Strings will be displayed in `font-lock-string-face'.
33 ;; Doc strings will be displayed in `font-lock-doc-string-face'.
34 ;; Function and variable names (in their defining forms) will be
35 ;; displayed in `font-lock-function-name-face'.
36 ;; Reserved words will be displayed in `font-lock-keyword-face'.
38 ;; To make the text you type be fontified, use M-x font-lock-mode.
39 ;; When this minor mode is on, the fonts of the current line are
40 ;; updated with every insertion or deletion.
42 ;; To define new reserved words or other patterns to highlight, use
43 ;; the `font-lock-keywords' variable. This should be mode-local.
45 ;; To turn this on automatically, add this to your .emacs file:
47 ;; (setq emacs-lisp-mode-hook '(lambda () (font-lock-mode 1)))
49 ;; On a Sparc2, the initial fontification takes about 12 seconds for a 120k
50 ;; file of C code, using the default configuration. You can speed this up
51 ;; substantially by removing some of the patterns that are highlighted by
52 ;; default. Fontifying Lisp code is significantly faster, because Lisp has a
53 ;; more regular syntax than C, so the expressions don't have to be as hairy.
