 v1 = Support for InterWiki links = ''(since [trac:milestone:0.10 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. At the extreme, InterWiki prefixes can even be used to simply introduce links to new protocols, such as tsvn: used by [trac:TortoiseSvn TortoiseSvn]. == 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 InterTrac prefixes, '''InterWiki prefixes are case insensitive'''. The target Wiki URL is looked up in 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. ---- {{{ PEP      http://www.python.org/peps/pep-$1.html # Python Enhancement Proposal$1 Trac-ML  http://thread.gmane.org/gmane.comp.version-control.subversion.trac.general/$1 # Message$1 in Trac Mailing List tsvn     tsvn:                                            # Interact with TortoiseSvn ...
