Interwiki Plugin

The InterwikiPlugin links ExternalSite:Page text to external sites based on aliases defined in the InterWikis topic. This plugin is inspired by UseMod Wiki's inter-wiki links, http://www.usemod.com/cgi-bin/wiki.pl?InterWiki.

Syntax Rules

• All ExternalSite aliases are defined in the InterWikis topic.
• Add and edit aliases in InterWikis.
• Each entry must be of format:
  | External site alias | URL | Tooltip help text |.
• Site aliases must start with an upper case letter and may contain alphanumeric letters.
• The URL and Tooltip Text may contain optional $page variables; the variable gets expanded to the page name.
• For TWiki sites, both the web and the topic have to be specified: TWikisite:Webname/SomePage
  • TWiki:Plugins/InterwikiPlugin or TWiki:Plugins.InterwikiPlugin
