Makes wikilinks clickable in the output window; contributed to the public domain by IceKarma on April 22, 2005.

Installation:

  1. Copy the code below into a file called wikilinks.js somewhere convenient (download raw source).
  2. Add it to Auto-load scripts on the Startup tab under Global Settings.
  3. If using Chatzilla on an XP box, place the file in %APPDATA%\Mozilla\Firefox\Profiles\????????.default\chatzilla\scripts. Then navigate to Chatzilla --> Preferences --> Global Settings --> Startup. Under Auto-load scripts, press the Add button and enter scripts/wikilinks.js. Press OK twice and restart Chatzilla. According to http://docs.dal.net/docs/chatzillaen.html, you can type /pref profilePath at a chat window to reveal your profile location.
  1. To install the script while ChatZilla is running, use the "/load file://" command in one of the views.

//***********************************************
// IceKarma's WikiLinks script for ChatZilla
// Version 1.2
//   1.2 by James Ross: fix the normal links by shunting the
//       word-hyphenator as well.
// Version 2.0
//   2.0 By Glen Mailer:
//        - Converted to new plugin API
//        - Ripped out a whole load of unused stuff
//        - Also Made to fit chatzilla coding pedantics
//   2.1 By Alphax:
//        - Added basic template linking functionality
//   2.2 By Alphax:
//        - subst: and pipes now handled correctly in templates
//   2.3 by Pathoschild:
//        - reverted to 2.2 (2.3 broke all links with non-interlanguage prefixes)
//        - fixed mailto: wikilink glitch (based on 2.3 code by Stigmj)
//   2.4 By Stigmj:
//        - added support for handling mirc-colors.
//   2.5 By GeorgeMoney:
//        - fixed for change in API

//        - fix broken interwiki prefix ([[w:foo]]);
//        - add support for namespace template syntax;
//        - fix modifiers msg, msgnw, raw; correct int (points to "mediawiki:foo", not "template:int:foo");
//        - don't link parameters: (([[template:foo|foo]]|bar)).
//   2.7 By Pathoschild:
//        - added support for external link syntax.
