Support for Inter Wiki links

(since 0.10)


An Inter Wiki 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.

At the extreme, Inter Wiki prefixes can even be used to simply introduce links to new protocols, such as tsvn: used by Tortoise Svn?.

Link Syntax


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

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

In addition to traditional Inter Wiki links, where the target is simply appended to the URL, Trac supports parametric Inter Wiki 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.


If the following is an excerpt of the Inter Map Txt 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.

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