Editing InterWiki

= 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. 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 {{{ <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 or 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 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 ...
