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. ---- {{{ 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 ... MeatBall http://www.usemod.com/cgi-bin/mb.pl? MetaWiki http://sunir.org/apps/meta.pl? MetaWikiPedia http://meta.wikipedia.org/wiki/ MoinMoin http://moinmoin.wikiwikiweb.de/ ... }}}
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".
