Description (last modified by )
Inside a wiki page [wiki: blah] works to link to the top level of the wiki; however, [trac:wiki: blah] doesn't work (I get a '"wiki:" is not a TracLinks' error).
If I turn intertrac compat mode, then the link works (because the originating Trac instance formats the link).

Same change than the inlined diff, plus some tests and a cosmetic change for the link title when there's no target.

I'm having this same exact problem in .11rc1 (windows). The most recent download at this time
was there a regression?
the exact error I get is:
Internal Error "wiki:" is not a TracLinks

What is currently implemented is the suggestion presented in comment:1, i.e. [<intertrac-prefix>:wiki].
However, I agree that [<intertrac-prefix>:wiki:] could be normalized to the same target.
I use this opportunity to add a reminder about another problem with InterTrac links:
[trac:SpamFilter SpamFilter], [trac:SpamFilter the SpamFilter]
renders as:
(while the second works as expected, the first also shows the trac: prefix when it shouldn't)

trac:prefix when it shouldn't)
That would be me in [6417], and it only occurs when the target and label are identical. Problem is that the _make_link() code does not know the differenence as the _lhref_formatter() sets label to target if no label is set before passing on to rendering.
The reason for wanting the prefix was to treat intertrac/wiki links like any other external link like http:// and similar. The default behaviour without label should include the external target.
I haven't looked into what that match argument passed in to _make_link() actually contains, but if that allows me to identify 'no label' it would just be a matter of changing if label == target: to something looking into the match object instead (formatter.py).

Seems match contains the full wiki link text. Using some string trickery, it should then be possible to detect if there is no actual label set when the strings are identical. This works when testing your examples:
-
trac/wiki/formatter.py
390 390 else: 391 391 return olabel or otarget 392 392 else: 393 if label == target: 393 if label == target \ 394 and match[match.find(label):].rstrip(']') == label: 394 395 # add ns for Inter* links when nothing is set 395 396 label = ns+':'+label 396 397 return self._make_intertrac_link(ns, target, label) or \

What about passing the fullmatch object to _make_link and look for the 'label'group? If present, then always use it, otherwise use ns:label because it will be either a shref or a lhref with no label set. That would be cleaner I think.

_make_link…
Yup. Makes more sense than trying to reparse it again. Committed in [7238:7239] for 0.11 and trunk.
That concludes the detour from the main ticket topic, I guess.

I'd like to renegotiate comment:6 ;-)
e.g. [trachacks:ThatPlugin] displaying the same as trachacks:ThatPlugin, i.e. trachacks:ThatPlugin instead of ThatPlugin.
Your reasoning was that trachacks: prefix should be shown always, like we do for [http://...], but I think that Inter* prefixes are more like realm prefixes and that we should hide them when seen inside [] brackets.
http: is special cased because of the target.startswith('//') test, for detecting whether the ns prefix is a communication protocol or not, obviously not the case here.
After all, one can always write a plain trachacks:ThatPlugin string when one wants to see that Inter* prefix.
With the current r6417 / r7239 behavior, we have no way of hiding the prefix (except from the heavy handed [trachacks:ThatPlugin ThatPlugin]).
So I'd like to revert this, especially now that the hack I suggested to you in comment:8 now gets in my way for reusing Formatter._make_link in another regexp …
Suggesting:
trac:wikior[trac:wiki]for linking to the Wiki module[trac:]for linking to the toplevel (#4314)Which can be implemented by removing a few checks in the intertrac module:
trac/wiki/intertrac.py
if not link:raise TracError('No TracLinks given')if href:req.redirect(href)aise TracError('"%s" is not a TracLinks' % link)Invalid InterTrac links will instead trigger a "No handler matched request to <link>" error.
