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: +;; +;; +;; (cond (window-system +;; (setq hilit-mode-enable-list '(not text-mode) +;; hilit-background-mode 'light +;; hilit-inhibit-hooks nil +;; hilit-inhibit-rebinding nil) +;; +;; (require 'hilit19) +;; )) +;; +;; If you like font-lock-mode and want to use both packages, then you can +;; disable hilit for the modes in which you want to use font-lock by listing +;; said modes in hilit-mode-enable-list. +;; +;; (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.
