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

53 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
55 ;; GENERAL OVERVIEW
57 ;; This package installs numerous hooks to colorfully highlight your
58 ;; source code buffers as well as mail and news buffers. Most
59 ;; programming languages have predefined highlighting patterns.
60 ;; Just load hilit19 and files will be automatically highlighted as
61 ;; they're loaded.
63 ;; Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L).
65 ;; If, when you edit the buffer, the coloring gets messed up, just
66 ;; redraw and the coloring will be adjusted. If automatic highlighting
67 ;; in the current buffer has been turned off, then typing C-u C-S-l will
68 ;; force a rehighlight of the entire buffer.
70 ;; Hilit19 can build faces by examining the names that you give to them
71 ;; For example, green/black-bold-italic-underline would be created as
72 ;; a face with a green foreground, and a black background, using a
73 ;; bold-italic font...with underlining for good measure.
75 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
77 ;; SETUP -- In your .emacs:
79 ;;
80 ;; (cond (window-system
81 ;; (setq hilit-mode-enable-list '(not text-mode)
82 ;; hilit-background-mode 'light
83 ;; hilit-inhibit-hooks nil
84 ;; hilit-inhibit-rebinding nil)
85 ;;
86 ;; (require 'hilit19)
87 ;; ))
88 ;;
89 ;; If you like font-lock-mode and want to use both packages, then you can
90 ;; disable hilit for the modes in which you want to use font-lock by listing
91 ;; said modes in hilit-mode-enable-list.
92 ;;
93 ;; (hilit-translate type 'RoyalBlue ; enable highlighting in C/C++
94 ;; string nil) ; disable string highlighting
96 ;; To get 100% of the utility of hilit19, you may also have to apply the
97 ;; patches below for info.el and vm5.33L_19/vm-summary.el
99 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
101 ;; SETUP -- Are you using the right font for Emacs?
103 ;; Emacs cannot properly find bold and italic fonts unless you specify a
104 ;; verbose X11 font name. If you specify a font for emacs in your
105 ;; .Xdefaults, it *MUST* be specified using the long form of the font name.
106 ;; Here's a good font menu:
108 ;; (setq
109 ;; x-fixed-font-alist
110 ;; '("Font Menu"
111 ;; ("Misc"

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

189 ;; bug fix for next-overlay-change and accompanying change to
190 ;; hilit-unhighlight-region

193 ;; minor change to fortran patterns

204 ;; Revision 2.12 1993/08/16 00:16:41 stig

208 ;; the pattern matcher now starts its searches from the end of the most
209 ;; recently highlighted region (which is not necessarily the end of the most
210 ;; recently matched regex).

215 ;; no longer use vm-summary-mode-hooks.
217 ;; some code moved from hilit-highlight-region to hilit-set-mode-patterns.

244 ;; added hilit-rehighlight-buffer-quietly to dired-after-readin-hook
246 ;; fixed bug in hilit-string-find that mishandled strings of the form: "\\"

259 ;; Revision 2.5 1993/07/28 05:02:56 stig
260 ;; improvements to makefile regular expressions
261 ;; removed about 130 lines just by compacting the big defconst for
262 ;; hilit-face-translation-table into a mapcar and defining a separate table
263 ;; of default faces.
265 ;; Revision 2.4 1993/07/27 14:09:05 stig
266 ;; documented another "known problem" to "head off gripe mail at the pass."
268 ;; Revision 2.3 1993/07/27 02:15:49 stig
269 ;; (hilit-lookup-face-create) incorporated patch which improves its behavior
270 ;; with more than one frame... Still can't have bold on the same face in two
271 ;; different fonts sizes at the same time...
273 ;; Revision 2.2 1993/07/27 02:02:59 stig
274 ;; vastly improved the makefile patterns
275 ;; added hook for mh-show-mode
277 ;; Revision 2.1 1993/07/24 17:46:21 stig
278 ;; Phasing out Info-select-hook... Version 19.18 will use Info-selection-hook.

286 ;; changed name of hilit-mode-alist to hilit-patterns-alist
287 ;; added hilit-message-quietly to mail-setup-hook
288 ;; added hilit-parser-alist which can be used to apply different patterns to
289 ;; different parts of a buffer. This could be integrated in a far more
290 ;; elegant manner, but it presently serves the purpose of not applying
291 ;; message header patterns to message bodies in mail-mode and its kin.

1491 ;; as you can see, I had two similar problems for Pascal and Icon. In
1492 ;; Pascal, strings are delimited with ' and an embedded quote is doubled,
1493 ;; thus string syntax would be extremely simple. However, if a string
1494 ;; occurs within a comment, the following text is considered a string.
1496 ;; In Icon, strings are similar to C ones, but there are also charsets,
1497 ;; delimited with simple quotes. I could not manage to use both regexps at
1498 ;; the same time.
1500 ;; The problem I have with my patterns for Icon is that this language has a
1501 ;; string similar constant to the C one (but a string can be cut on several
1502 ;; lines, if terminated by a dash and continued with initial blanks, like
1503 ;; this:
1504 ;; "This is a somewhat long -
1505 ;; string, written on three -
1506 ;; successive lines"
1507 ;; in order to insert a double quote in a string, you have to escape it
1508 ;; with a \), bu also a character set constant (named a charset), which
1509 ;; uses single quotes instead of double ones. It would seem intuitive to
1510 ;; highlight both constants in the same way.
