| 24 | ;; Hilit19.el is a customizable highlighting package for Emacs19. It supports |
| 25 | ;; not only source code highlighting, but also Info, RMAIL, VM, gnus... |
| 26 | ;; Hilit19 knows (or thinks it knows) how to highlight emacs buffers in |
| 27 | ;; about 25 different modes. |

| 51 | ;; GENERAL OVERVIEW |
| 52 | ;; |
| 53 | ;; This package installs numerous hooks to colorfully highlight your |
| 54 | ;; source code buffers as well as mail and news buffers. Most |
| 55 | ;; programming languages have predefined highlighting patterns. |
| 56 | ;; Just load hilit19 and files will be automatically highlighted as |
| 57 | ;; they're loaded. |
| 58 | ;; |
| 59 | ;; Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L). |
| 60 | ;; |
| 61 | ;; If, when you edit the buffer, the coloring gets messed up, just |
| 62 | ;; redraw and the coloring will be adjusted. If automatic highlighting |
| 63 | ;; in the current buffer has been turned off, then typing C-u C-S-l will |
| 64 | ;; force a rehighlight of the entire buffer. |
| 65 | ;; |
| 66 | ;; Hilit19 can build faces by examining the names that you give to them |
| 67 | ;; For example, green/black-bold-italic-underline would be created as |
| 68 | ;; a face with a green foreground, and a black background, using a |
| 69 | ;; bold-italic font...with underlining for good measure. |
| 70 | ;; |
| 71 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; |
| 72 | ;; |
| 73 | ;; SETUP -- In your .emacs: |
| 74 | ;; |
| 75 | ;; |
| 76 | ;; (cond (window-system |
| 77 | ;; (setq hilit-mode-enable-list '(not text-mode) |
| 78 | ;; hilit-background-mode 'light |
| 79 | ;; hilit-inhibit-hooks nil |
| 80 | ;; hilit-inhibit-rebinding nil) |
| 81 | ;; |
| 82 | ;; (require 'hilit19) |
| 83 | ;; )) |
| 84 | ;; |
| 85 | ;; If you like font-lock-mode and want to use both packages, then you can |
| 86 | ;; disable hilit for the modes in which you want to use font-lock by listing |
| 87 | ;; said modes in hilit-mode-enable-list. |
| 88 | ;; |
| 89 | ;; (hilit-translate type 'RoyalBlue ; enable highlighting in C/C++ |
| 90 | ;; string nil) ; disable string highlighting |
| 91 | ;; |
| 92 | ;; To get 100% of the utility of hilit19, you may also have to apply the |
| 93 | ;; patches below for info.el and vm5.33L_19/vm-summary.el |
| 94 | ;; |
| 95 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; |
| 96 | ;; |
| 97 | ;; SETUP -- Are you using the right font for Emacs? |
| 98 | ;; |
| 99 | ;; Emacs cannot properly find bold and italic fonts unless you specify a |
| 100 | ;; verbose X11 font name. If you specify a font for emacs in your |
| 101 | ;; .Xdefaults, it *MUST* be specified using the long form of the font name. |
| 102 | ;; Here's a good font menu: |
| 103 | ;; |

| 133 | ;; KNOWN BUGS/TO DO LIST/HELP WANTED/APPLY WITHIN |
| 134 | ;; |
| 135 | ;; * unbalanced, unescaped double quote characters can confuse hilit19. |
| 136 | ;; This will be fixed someday, so don't bug me about it. |
| 137 | ;; |
| 138 | ;; * ALTHOUGH HILIT19 IS FASTER THAN FONT-LOCK-MODE... |
| 139 | ;; For various reasons, the speed of the package could still stand to be |
| 140 | ;; improved. If you care to do a little profiling and make things tighter... |
| 141 | ;; |
| 142 | ;; * hilit-toggle-highlight is flaky when auto-rehighlight is neither t nor nil. |
| 143 | ;; Does anyone actually USE this? I think I might just remove it. |
| 144 | ;; |
| 145 | ;; PROJECTS THAT YOU CAN TAKE OVER BECAUSE I DON'T MUCH CARE ABOUT THEM... |
| 146 | ;; |
| 147 | ;; * Moved hilit-wysiwyg-replace here from my version of man.el, this is not |
| 148 | ;; a bug. The bug is that I don't have a reverse operation yet...just a |
| 149 | ;; stub Wysiwyg-anything really belongs in a package of it's own. |

| 1515 | ;; lines, if terminated by a dash and continued with initial blanks, like |
| 1516 | ;; this: |
