Support for InterWiki links

(since 0.10)

Definition

An InterWiki link can be used for referring to a Wiki page located in another Wiki system, and by extension, to any object located in any other Web application, provided a simple URL mapping can be done.

Link Syntax

<target_wiki>(:<identifier>)+

The link is composed by the targeted Wiki (or system) name, followed by a column (e.g. MeatBall:), followed by a page specification in the target. Note that, as for InterTrac prefixes, InterWiki prefixes are case insensitive.

The target Wiki URL is looked up in a the InterMapTxt wiki page, modelled after MeatBall:InterMapTxt.

In addition to traditional InterWiki links, where the target is simply appended to the URL, Trac supports parametric InterWiki URLs: identifiers $1, $2, ... in the URL will be replaced by corresponding arguments. The argument list is formed by splitting the page identifier using the ":" separator.

Examples

If the following is an excerpt of the InterMapTxt page:

= InterMapTxt =
== This is the place for defining InterWiki prefixes ==

Currently active prefixes: [[InterWiki]]

This page is modelled after the MeatBall:InterMapTxt page.
In addition, an optional comment is allowed after the mapping.

Then,

  • MoinMoin:InterWikiMap should be rendered as MoinMoin:InterWikiMap and the title for that link would be "InterWikiMap in MoinMoin"
  • TracML:4346 should be rendered as TracML:4346 and the title for that link would be "Message 4346 in Trac Mailing List"
