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

• Enter ExternalSite:Page to create a link that points to the Page on the ExternalSite server.
  • If Page contains spaces, it can be enclosed in single or double quotes. Example: MySite:'My Photo.jpg'. Special characters contained within the quotes are URL encoded.
• Enter [[ExternalSite:Page][any label]] to specify a custom label.
• 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 fromatting tokens; the token gets expanded to the page name.

For Foswiki and TWiki sites, both the web and the topic have to be specified: Foswiki:Webname/SomePage

Foswiki:Extensions/InterwikiPlugin or Foswiki:Extensions.InterwikiPlugin

For links with paranthesis you will need to write as [[Wikipedia:Fork_(software_development)]], or quoted, as Wikipedia:'Fork_(software_development)' as we assume that the closing paranthesis is not part of the link. For example, Wikipedia:Fork_(software_development) .

InterwikiPlugin Settings

You can override the default settings using preferences. These preferences can be set in your SitePreferences, or in WebPreferences, or in individual topics.

Preference	Use to	Default
INTERWIKIPLUGIN_RULESTOPIC	The topic(s) containing the inter-wiki rules. Can be a comma separated list. See InterWikis#AddingYourOwn for more details	InterWikis
INTERWIKIPLUGIN_INTERLINKFORMAT	Set the interlink format	<a class="interwikiLink" href="$url" title="$tooltip" class="interwikiLink"><noautolink>$label</noautolink></a>

The INTERWIKIPLUGIN_INTERLINKFORMAT supports a number of formatting tokens:

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