|
||
|
||
;; Hilit19.el is a customizable highlighting package for Emacs19. It supports
|
||
;; not only source code highlighting, but also Info, RMAIL, VM, gnus...
|
||
;; Hilit19 knows (or thinks it knows) how to highlight emacs buffers in
|
||
;; about 25 different modes.

|
||
;; GENERAL OVERVIEW
|
||
;;
|
||
;; This package installs numerous hooks to colorfully highlight your
|
||
;; source code buffers as well as mail and news buffers. 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. If you specify a font for emacs in your
|
||
;; .Xdefaults, it *MUST* be specified using the long form of the font name.
|
||
;; Here's a good font menu:
|
||
;;
|
||
;; (setq
|
||
;; x-fixed-font-alist

;; KNOWN BUGS/TO DO LIST/HELP WANTED/APPLY WITHIN
|
||
;;
|
||
;; * unbalanced, unescaped double quote characters can confuse hilit19.
|
||
;; This will be fixed someday, so don't bug me about it.
|
||
;;
|
||
;; * ALTHOUGH HILIT19 IS FASTER THAN FONT-LOCK-MODE...
|
||
;; For various reasons, the speed of the package could still stand to be
|
||
;; improved. If you care to do a little profiling and make things tighter...
|
||
;;
|
||
;; * hilit-toggle-highlight is flaky when auto-rehighlight is neither t nor nil.
|
||
;; Does anyone actually USE this? I think I might just remove it.
|
||
;;
|
||
;; PROJECTS THAT YOU CAN TAKE OVER BECAUSE I DON'T MUCH CARE ABOUT THEM...
|
||
;;
|
||
;; * Moved hilit-wysiwyg-replace here from my version of man.el, this is not
|
||
;; a bug. The bug is that I don't have a reverse operation yet...just a
|
||
;; stub Wysiwyg-anything really belongs in a package of it's own.
