Most ;; programming languages have predefined highlighting patterns. ;; Just load hilit19 and files will be automatically highlighted as ;; they're loaded. ;; ;; Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L). ;; ;; If, when you edit the buffer, the coloring gets messed up, just ;; redraw and the coloring will be adjusted. If automatic highlighting ;; in the current buffer has been turned off, then typing C-u C-S-l will ;; force a rehighlight of the entire buffer. ;; ;; Hilit19 can build faces by examining the names that you give to them ;; For example, green/black-bold-italic-underline would be created as ;; a face with a green foreground, and a black background, using a ;; bold-italic font...with underlining for good measure. ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; ;; SETUP -- In your .emacs: ;; ;; (require 'hilit19) ; not intended to be autoloaded ;; ;; (setq hilit-mode-enable-list '(not text-mode)) ;; ;; (hilit-translate type 'RoyalBlue ; enable highlighting in C/C++ ;; string nil) ; disable string highlighting ;; ;; To get 100% of the utility of hilit19, you may also have to apply the ;; patches below for info.el and vm5.33L_19/vm-summary.el ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; ;; SETUP -- Are you using the right font for Emacs? ;; ;; Emacs cannot properly find bold and italic fonts unless you specify a ;; verbose X11 font name.

This could be integrated in a far more ;; elegant manner, but it presently serves the purpose of not applying ;; message header patterns to message bodies in mail-mode and it's kin. ;; hilit-set-mode-patterns now takes a list of modes and an optional parse-fn ;; V1.8 19-July-1993 Stig@netcom.com ;; changed hilit-translate to be a macro so that now it mirrors setq ;; now permit multiple layers of face-translation... ;; hilit-lookup-face-create now parses background colors ;; added code to check for face changes and recopy the fonts from 'default ;; when necessary. this can be disabled if you never change fonts. ;; you should be able to change fonts, redraw, and have all of your ;; bold & italic faces back to normal.
