I've posted two proposals:
http://dev.zope.org/Zope3/TALESPathExpressionAdapters
Proposes a mechanism for easily using adapters in TALES expressions.
http://dev.zope.org/Zope3/ZPTVariableNamespaces
proposes a mechanism for qualifying names defined in TAL and used in TALES expressions.
Based on initial comments, I've retracted ZPTVariableNamespaces and updated:
http://dev.zope.org/Zope3/TALESPathExpressionAdapters
I've thrown out a few more spellings for adapter use:
ob->adaptername context->dc/title
ob~adaptername context~dc/title
ob[adaptername] context[dc]/title
Of course, Steve suggested:
ob:adaptername context:dc/title
So far the cast syntax seems to be the most popular:
(adaptername)ob (dc)context/title
with one dissension. :)
One disadvantage I see with the cast notation is that it's a bit jarring in:
a/b/(adapter)c/d
as the adapter is applied to a/b/c. The order just doesn't seem quite right.
I'd love to get more feedback or suggestions for the syntax.
As far as in-template definition, I'd like to borrow from Evan's work and allow 'adapter' to be used like 'local' or 'global' in tal:define:
tal:define="adapter dc modules/zope.app.dublincore/IZopeDublinCore"
Thoughts?
Jim
P.S. Thanks for all the comments so far. :)
