InterWiki links support

[daniel]

It'd be sweet to have support for InterWiki links in wiki pages.

I just added support for InterWiki links to my local Trac state, of a kind. In trac.ini, I added a section:

[interwiki]
trac = http://foo.com/projects/$page/trac.cgi/wiki

I then fiddled Wiki.py around to check those options when it encountered an unknown module link, changed the url regexps to match modules as well as other URLs (and also to limit the character set more rigidly), and removed the obsoleted modulehref regexp. Upshot is, with the above setting, the following section renders correctly:

[trac:foo An InterWiki link][[BR]]
trac:foo[[BR]]
http://foo.com[[BR]]
Apache::Session[[BR]]
source:/trunk/README[[BR]]

In current trac, this renders as:

An InterWiki link
trac:foo[[BR]] http://foo.com[[BR]] Apache::Session
source:/trunk/README[[BR]]

I'll attach a patch, but my local copy of Wiki.py is very heavily modified, since we use a TWiki in other contexts and sharing the syntax was desirable. (It's going to get even more heavily modified, since TWiki syntax more or less requires you to examine context around a match, and Trac's approach means anything in that context cannot be used in other Wiki markup ...)

Patch against 0.7.1 to support InterWiki links

[cboos]

I've updated the InterTrac page to include a specification for InterWiki support.

[cboos]

The support for InterWiki links has been implemented in the InterTrac branch.

You can check it out, at revision r1912:

svn co http://svn.edgewall.com/repos/trac/branches/cboos-dev/intertrac-branch

[cboos]

This will be post-poned to 1.0.

The InterTrac branch will be actively maintained meanwhile, and a patch for each released 0.9 version will be attached to ticket #234.

[cboos]

In fact, I created a special purpose ticket for the branch integration: #2041. You can find the patches against 0.9.x there.

[cboos]

InterWiki links are now part of the mainstream Trac, since r2839.
