Support for InterWiki links

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.

InterWiki prefixes can even be used to introduce links to new protocols, such as tsvn: used by TortoiseSvn.

Link Syntax

<target_wiki>(:<identifier>)+

The link is composed by the targeted Wiki (or system) name, followed by a colon, eg 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 the [interwiki] section of TracIni and in the InterMapTxt wiki page, modeled after MeatBall:InterMapTxt. If a prefix is defined in both the [interwiki] section and InterMapTxt, the [interwiki] section takes precedence.

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.

[interwiki]

Every option in the [interwiki] section in TracIni defines one InterWiki prefix. The option name defines the prefix. The option value defines the URL, optionally followed by a description separated from the URL by whitespace. Parametric URLs are supported as well.

Example:

[interwiki]
MeatBall = http://www.usemod.com/cgi-bin/mb.pl?
PEP = http://www.python.org/peps/pep-$1.html Python Enhancement Proposal $1
tsvn = tsvn: Interact with TortoiseSvn

Examples

For the following 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 will be rendered as MoinMoin:InterWikiMap and the title for that link will be "InterWikiMap in MoinMoin".
  • Trac-ML:4346 will be rendered as Trac-ML:4346 and the title for that link will be "Message 4346 in Trac Mailing List".
