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

52 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
54 ;; GENERAL OVERVIEW
56 ;; This package installs numerous hooks to colorfully highlight your
57 ;; source code buffers as well as mail and news buffers. Most
58 ;; programming languages have predefined highlighting patterns.
59 ;; Just load hilit19 and files will be automatically highlighted as
60 ;; they're loaded.
62 ;; Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L).
64 ;; If, when you edit the buffer, the coloring gets messed up, just
65 ;; redraw and the coloring will be adjusted. If automatic highlighting
66 ;; in the current buffer has been turned off, then typing C-u C-S-l will
67 ;; force a rehighlight of the entire buffer.
69 ;; Hilit19 can build faces by examining the names that you give to them
70 ;; For example, green/black-bold-italic-underline would be created as
71 ;; a face with a green foreground, and a black background, using a
72 ;; bold-italic font...with underlining for good measure.
74 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
76 ;; SETUP -- In your .emacs:
78 ;;
79 ;; (cond (window-system
80 ;; (setq hilit-mode-enable-list '(not text-mode)
81 ;; hilit-background-mode 'light
82 ;; hilit-inhibit-hooks nil
83 ;; hilit-inhibit-rebinding nil)
84 ;;
85 ;; (require 'hilit19)
86 ;; ))
87 ;;
88 ;; If you like font-lock-mode and want to use both packages, then you can
89 ;; disable hilit for the modes in which you want to use font-lock by listing
90 ;; said modes in hilit-mode-enable-list.
91 ;;
92 ;; (hilit-translate type 'RoyalBlue ; enable highlighting in C/C++
93 ;; string nil) ; disable string highlighting
95 ;; To get 100% of the utility of hilit19, you may also have to apply the
96 ;; patches below for info.el and vm5.33L_19/vm-summary.el
98 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
100 ;; SETUP -- Are you using the right font for Emacs?
102 ;; Emacs cannot properly find bold and italic fonts unless you specify a
103 ;; verbose X11 font name. If you specify a font for emacs in your
104 ;; .Xdefaults, it *MUST* be specified using the long form of the font name.
105 ;; Here's a good font menu:

108 ;; x-fixed-font-alist

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

187 ;; Revision 2.16 1993/08/22 19:46:00 stig
188 ;; bug fix for next-overlay-change and accompanying change to
189 ;; hilit-unhighlight-region

192 ;; minor change to fortran patterns
194 ;; Revision 2.14 1993/08/17 14:12:10 stig
195 ;; added default face mapping for 'formula' which is needed for new latex
196 ;; patterns.

203 ;; Revision 2.12 1993/08/16 00:16:41 stig
204 ;; changed references to default-bold-italic to just bold-italic because the
205 ;; font for that face is maintained by emacs.
207 ;; the pattern matcher now starts it's searches from the end of the most
208 ;; recently highlighted region (which is not necessarily the end of the most
209 ;; recently matched regex).
211 ;; multiple errors in pattern matcher now just give an error instead of lots of

234 ;; parameter is now stored in hilit-patterns-alist.
236 ;; Revision 2.8 1993/08/12 22:05:03 stig

239 ;; twiddled some of the color defaults for dark backgrounds
241 ;; always get 'mono color defaults if (not (x-display-color-p))
243 ;; added hilit-rehighlight-buffer-quietly to dired-after-readin-hook
245 ;; fixed bug in hilit-string-find that mishandled strings of the form: "\\"
247 ;; NEW FUNCTION: hilit-add-mode-pattern... kinda like add-hook for patterns

258 ;; Revision 2.5 1993/07/28 05:02:56 stig
259 ;; improvements to makefile regular expressions
260 ;; removed about 130 lines just by compacting the big defconst for
261 ;; hilit-face-translation-table into a mapcar and defining a separate table
262 ;; of default faces.
264 ;; Revision 2.4 1993/07/27 14:09:05 stig
265 ;; documented another "known problem" to "head off gripe mail at the pass."
267 ;; Revision 2.3 1993/07/27 02:15:49 stig
268 ;; (hilit-lookup-face-create) incorporated patch which improves it's behavior
269 ;; with more than one frame... Still can't have bold on the same face in two
270 ;; different fonts sizes at the same time...
272 ;; Revision 2.2 1993/07/27 02:02:59 stig
273 ;; vastly improved the makefile patterns
274 ;; added hook for mh-show-mode
276 ;; Revision 2.1 1993/07/24 17:46:21 stig
277 ;; Phasing out Info-select-hook... Version 19.18 will use Info-selection-hook.
279 ;; Revision 2.0 1993/07/24 13:50:10 stig
280 ;; better documentation and added the function hilit-submit-feedback.

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

1488 ;; as you can see, I had two similar problems for Pascal and Icon. In
1489 ;; Pascal, strings are delimited with ' and an embedded quote is doubled,
1490 ;; thus string syntax would be extremely simple. However, if a string
1491 ;; occurs within a comment, the following text is considered a string.
1493 ;; In Icon, strings are similar to C ones, but there are also charsets,
1494 ;; delimited with simple quotes. I could not manage to use both regexps at
1495 ;; the same time.
1497 ;; The problem I have with my patterns for Icon is that this language has a
1498 ;; string similar constant to the C one (but a string can be cut on several
1499 ;; lines, if terminated by a dash and continued with initial blanks, like
1500 ;; this:
1501 ;; "This is a somewhat long -
1502 ;; string, written on three -
1503 ;; successive lines"
1504 ;; in order to insert a double quote in a string, you have to escape it
1505 ;; with a \), bu also a character set constant (named a charset), which
1506 ;; uses single quotes instead of double ones. It would seem intuitive to
1507 ;; highlight both constants in the same way.
