[Zope3-Users] test() in TALES in Zope3

[Frank Burkhardt]

Hi,

in Zope2 there's a test() method that can be used in TAL (*). Is there something
comparable in Zope3?

I know how to write such a method but how to make it available in the
namespace of TALES-"python:"-expressions? I would like to write expressions
like this:

<div tal:attributes="class python: 'foo' + test(condition == True,' bar','')" />

Is this possible?

Regards,

Frank
