Thanks Crawford, very quick turn-around!

Please follow-up in the new TWiki:Codev/SearchWithTWikiQueryLanguage topic.

See QuerySearch for the working syntax.

Waiting for release (well feedback as well, but if there is none it'll go as it is)

See Item4165: stringent IF syntax breaks templates

Now I am totally unclear on what syntax I need to use.

If I use %IF{ "defined USERLAYOUTURL" I get an error that no context is found.
If I use %IF{ "'$ USERLAYOUTURL = ''" I get this generated HTML: IF{ "'$ USERLAYOUTURL = ''" then="@import url('');" }: Syntax error in ''$ USERLAYOUTURL = ''' at '''

Also in the login template I cannot get the ERROR variable evaluated 'not empty'.

%IF{"'$ ERROR' != ''" then="%BR% _Error: %ERROR%_"}%

gives me the message with empty ERROR.

Also the "context" identifier leads to confusion. Is it correct that I need to write:

%IF{ "'context TablePluginEnabled'"

with additional single quotes? I get an error otherwise. But the doc is not clear on this.

Thanks for highlighting this Arthur; it's possible that all you need to do is svn up - please try that first.

You are supposed to be able to use all the expressions you wrote above. Specifically the 'defined', 'context' and '$' operators are all supposed to accept an unquoted argument.

I will investigate; can you provide me with an example (which template breaks).

Thanks

NOTE: please track this in Item4165
