;; Hilit19.el is a customizable highlighting package for Emacs 19. 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
;; '("Font Menu"
;; ("Misc"
;; ("6x12" "-misc-fixed-medium-r-semicondensed--12-110-75-75-c-60-*-1")

;; 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 its own.

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

;;
;; Revision 2.14 1993/08/17 14:12:10 stig

;;
;; twiddled the calendar-mode patterns a bit.
;;
;; Revision 2.13 1993/08/16 04:33:54 stig

;; font for that face is maintained by emacs.
;;
;; the pattern matcher now starts its searches from the end of the most

;; recently matched regex).
;;
;; multiple errors in pattern matcher now just give an error instead of lots of
;; annoying messages and dings.
;;
;; no longer use vm-summary-mode-hooks.
;;
;; some code moved from hilit-highlight-region to hilit-set-mode-patterns.

;; pattern changes to C/C++, latex, texinfo, fortran, nroff, etc.
;;
;; Revision 2.11 1993/08/13 12:12:37 stig

;; parameter is now stored in hilit-patterns-alist.
;;
;; Revision 2.8 1993/08/12 22:05:03 stig
;; fixed some typos in documentation
;;
;; twiddled some of the color defaults for dark backgrounds
;;
;; always get 'mono color defaults if (not (x-display-color-p))
;;
;; added hilit-rehighlight-buffer-quietly to dired-after-readin-hook
;;
;; fixed bug in hilit-string-find that mishandled strings of the form: "\\"
;;
;; NEW FUNCTION: hilit-add-mode-pattern... kinda like add-hook for patterns
;;
;; fixed minor pattern bugs for latex-mode and emacs-lisp-mode
;;
;; Revision 2.7 1993/07/30 02:43:01 stig
;; added const to the list of modifiers for C/C++ types
;;
;; Revision 2.6 1993/07/30 00:30:54 stig
;; now permit selection of arbitrary subexpressions for highlighting...
;; fixed keyword patterns for C/C++ using this technique.
;;
;; Revision 2.5 1993/07/28 05:02:56 stig
;; improvements to makefile regular expressions
;; removed about 130 lines just by compacting the big defconst for
;; hilit-face-translation-table into a mapcar and defining a separate table
;; of default faces.
;;
;; Revision 2.4 1993/07/27 14:09:05 stig
;; documented another "known problem" to "head off gripe mail at the pass."
;;
;; Revision 2.3 1993/07/27 02:15:49 stig
;; (hilit-lookup-face-create) incorporated patch which improves its behavior
;; with more than one frame... Still can't have bold on the same face in two
;; different fonts sizes at the same time...
;;
;; Revision 2.2 1993/07/27 02:02:59 stig
;; vastly improved the makefile patterns
;; added hook for mh-show-mode
;;
;; Revision 2.1 1993/07/24 17:46:21 stig
;; Phasing out Info-select-hook... Version 19.18 will use Info-selection-hook.
;;
;; Revision 2.0 1993/07/24 13:50:10 stig
;; better documentation and added the function hilit-submit-feedback.
;; C-S-l (control shift l) repaints the buffer. Other bindings are optional.
;; multi-line highlights no longer cause problems when
;; hilit-auto-rehighlight is 'visible
;; added hilit-predefined-face-list...
;; changed name of hilit-mode-alist to hilit-patterns-alist
;; added hilit-message-quietly to mail-setup-hook
;; added hilit-parser-alist which can be used to apply different patterns to
;; different parts of a buffer. 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 its kin.
;; hilit-set-mode-patterns now takes a list of modes and an optional parse-fn

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