  31 ;; not only source code highlighting, but also Info, RMAIL, VM, gnus...
  32 ;; Hilit19 knows (or thinks it knows) how to highlight emacs buffers in

  56 ;; GENERAL OVERVIEW
  57 ;;
  58 ;;      This package installs numerous hooks to colorfully highlight your
  59 ;;      source code buffers as well as mail and news buffers.  Most
  60 ;;      programming languages have predefined highlighting patterns.
  61 ;;      Just load hilit19 and files will be automatically highlighted as
  62 ;;      they're loaded.
  63 ;;
  64 ;;      Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L).
  65 ;;
  66 ;;      If, when you edit the buffer, the coloring gets messed up, just
  67 ;;      redraw and the coloring will be adjusted.  If automatic highlighting
  68 ;;      in the current buffer has been turned off, then typing C-u C-S-l will
  69 ;;      force a rehighlight of the entire buffer.
  70 ;;
  71 ;;      Hilit19 can build faces by examining the names that you give to them
  72 ;;      For example, green/black-bold-italic-underline would be created as
  73 ;;      a face with a green foreground, and a black background, using a
  74 ;;      bold-italic font...with underlining for good measure.
  75 ;;
  76 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
  77 ;;
  78 ;; SETUP -- In your .emacs:
  79 ;;
  80 ;;
  81 ;; (cond (window-system
  82 ;;        (setq hilit-mode-enable-list  '(not text-mode)
  83 ;;              hilit-background-mode   'light
  84 ;;              hilit-inhibit-hooks     nil
  85 ;;              hilit-inhibit-rebinding nil)
  86 ;;
  87 ;;        (require 'hilit19)
  88 ;;        ))
  89 ;;
  90 ;; If you like font-lock-mode and want to use both packages, then you can
  91 ;; disable hilit for the modes in which you want to use font-lock by listing
  92 ;; said modes in hilit-mode-enable-list.
  93 ;;
  94 ;;      (hilit-translate type     'RoyalBlue   ; enable highlighting in C/C++
  95 ;;                       string   nil)         ; disable string highlighting
  96 ;;
  97 ;; To get 100% of the utility of hilit19, you may also have to apply the
  98 ;; patches below for info.el and vm5.33L_19/vm-summary.el
  99 ;;
 100 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
 101 ;;
 102 ;; SETUP -- Are you using the right font for Emacs?
 103 ;;
 104 ;; Emacs cannot properly find bold and italic fonts unless you specify a
 105 ;; verbose X11 font name.  If you specify a font for emacs in your
 106 ;; .Xdefaults, it *MUST* be specified using the long form of the font name.
 107 ;; Here's a good font menu:
 108 ;;
 109 ;; (setq
 110 ;;  x-fixed-font-alist
 111 ;;  '("Font Menu"
 112 ;;    ("Misc"

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

1502 ;; as you can see, I had two similar problems for Pascal and Icon. In
1503 ;; Pascal, strings are delimited with ' and an embedded quote is doubled,
1504 ;; thus string syntax would be extremely simple. However, if a string
1505 ;; occurs within a comment, the following text is considered a string.
1506 ;;
1507 ;; In Icon, strings are similar to C ones, but there are also charsets,
1508 ;; delimited with simple quotes. I could not manage to use both regexps at
1509 ;; the same time.
1510
1511 ;; The problem I have with my patterns for Icon is that this language has a
1512 ;; string similar constant to the C one (but a string can be cut on several
1513 ;; lines, if terminated by a dash and continued with initial blanks, like
1514 ;; this:
1515 ;;         "This is a somewhat long -
1516 ;;          string, written on three -
1517 ;;          successive lines"
1518 ;; in order to insert a double quote in a string, you have to escape it
1519 ;; with a \), bu also a character set constant (named a charset), which
1520 ;; uses single quotes instead of double ones. It would seem intuitive to
1521 ;; highlight both constants in the same way.
