What is the easiest way to automatically link the pattern /r(\d+)/ to a URL like http://code.google.com/p/qubit-toolkit/source/detail?r=%5C1 wherever it appears in MediaWiki articles?
If you don't mind patching the MediaWiki core, a simple change to Parser::doMagicLinks() ought to do it. I can't offhand think of any particularly convenient way to do that from an extension, though; all the hooks I can see in the general vicinity are either a bit too early or a bit too late.
