Link ExternalSite:Page text to external sites based on aliases defined in a rules topic

Introduction

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

Enter ExternalSite:Page to create a link that points to the Page on the ExternalSite server. For example, type RFC:2397 to get RFC:2397.
Enter [[ExternalSite:Page][any label]] to specify a custom label.
All ExternalSite aliases are defined in the InterWikis topic.
Optionally, the Page can be enclosed in single quotes or double quotes. Use quotes if your Page contains spaces or other special characters. Links of quoted pages are URL encoded. Example: Photos:"San Francisco Trip 2011".
Add and edit aliases in InterWikis (or the one specified in the INTERWIKIPLUGIN_RULESTOPIC setting).
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

InterwikiPlugin Settings

This plugin can be configured with preferences settings in Main.TWikiPreferences (site level), a WebPreferences (web level) or in a topic (page level). Do not change the settings here, they are here only to illustrate the default values. To overload, copy the settings to one of the aforementioned topics.

Link rules topic name: (default is InterWikis)
- Set INTERWIKIPLUGIN_RULESTOPIC = InterWikis

Inter-link format, with variables:

$site	Site alias
$page	Page (part after colon)
$url	Site URL (might contain $page)
$label	Equal to $site:$page
$tooltip	Tooltip message

Set INTERWIKIPLUGIN_INTERLINKFORMAT = $label
