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

|
||||
