User-defined trac links using same colon syntax as reports, tickets etc

[walter.nicholls@…]

Add ability to map TracLink -style prefixes to URLs. For example define somewhere that text with a "case:" prefix, eg:

  case:123

.. is mapped to the hyperlink

  http://mycrmserver/viewcase.php?case_number=123

This should also support long text descriptions as described in #185, ie

  [case:123 Request from Allied Widgets inc for this report]

This can be done in a clumsy way now with a WikiMacro, but this does not work inside subversion change comments, which is where I would find it most useful.

Possible implementation: could be defined in trac.ini like so:

  [linktranslation]
   case = http://remedy.foocorp.com/case/#1 

This would require changes to the Wiki parser to build the regular expressions more dynamically than currently.

The output of this could be rendered as an external link, even better would be if this was configurable.

Also, would be nice if we could override the standard ones, etc make "ticket:" point to our own trouble ticket system, outside of Trac.

Though the plan is certainly to support TracLinks extensions with modules once we have pluggable modules, I nevertheless think that the lightweight TracLinks you suggested are worth implementing.

I'm currently refactoring the WikiFormatter.py to make it a little bit more modular, in source:branches/cboos-dev/intertrac-branch/trac/WikiFormatter.py (though I haven't commited anything there, as of this writting)

With my changes, it will be esay to implement this enhancement request.

E.g: mantis:0000542 should be replaced by http://dmachine/mantis/bug_view_page.php?bug_id=0000542 if I have:

[linktranslation]
   mantis = http://dmachine/mantis/bug_view_page.php?bug_id=$1 

(#1 might be a valid part of the URL, whereas $ is seldom used in URLs, right?)

[1856] adds a TracPluggableModules extension for allowing components to provide their Wiki link syntax.

I'll leave this open for the suggested configurable formats in the TracIni.

[cboos]

This feature has been implemented in r1908 in the InterTrac branch, as an extension to traditional InterWiki links.

[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]

TODO also use the arguments in the description, e.g.

{{{
...
TracDev http://thread.gmane.org/gmane.comp.version-control.subversion.trac.devel/%1         # Mail [%1] in Trac-Dev mailing List
...
}}}

Why high priority? It should already be possible to do this with a plugin.

[cboos]

… because it's already there in the InterTrac branch, and I see no need to ask users to get a plugin for this when it can easily be part of the core InterWiki functionality.

Actually, those plugins wouldn't even exist if the InterTrac branch had been merged earlier, as this is working for more than half a year already.

[cboos]

This feature is now availabe for trunk (r2839), as part of the InterWiki. See InterMapTxt for the documentation.
