I'm pretty sure that this is covered somewhere in the docs, but I was unable to find it, except for the rudimentary Linking Cases. I'm looking for a complete reference on what is auto-linked in the bug event text. I know of the following patterns:
links to cases
case XXX (site localized name for "case")
bug XXX
bugs ID: XXX
bugz ID: XXX
bugzid: XXX
link to wikis
WXXX
Article XXX (including localized names for "article")
Wiki XXX (link to wiki page XXX)
webpage urls
http://url (link to URL)
https://url (link to URL)
Are there more?
Edit: Still looking for documentation.
However, in the meantime, I asked the source - and I believe that there is a bug in FogBugz... in the static (!) constructor of CBugRelationList the patterns are apparently built for case/bug and wiki matching. However, in contrast to the wiki pattern which uses FB_*_ALL (containing a static list of localized entries), the case pattern uses FB_CASE which is a localizable entry which may change depending on the language of the current CLocalizer instance. However, since the pattern is static, it will not match other patterns anymore such as the German "Fall XXX", which used to get matched in FB6 AFAIR.
