= Support for InterWiki links = ''(since [milestone: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 == {{{ (:)+ }}} 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 [http://www.usemod.com/cgi-bin/mb.pl?InterMapTxt 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. ---- {{{ PEP http://www.python.org/peps/pep-$1.html # Python Enhancement Proposal $1 TracML http://thread.gmane.org/gmane.comp.version-control.subversion.trac.general/$1 # Message $1 in Trac Mailing List ...
