For the most part, yes, but additional namespaces didn't occur to us when implementing ZPT, and it is hardly trivial to define how such extensibility should work.
After having a look into TALInterpreter.py I think a have a clue, why this is complicated. *sign* Otherwise: TALInterpreter uses bytecode_handlers, thus adding new bytecodes should be quite easy. So the only problem being left (as far as I can see) is: how to make adding bytecodes or namespaces extensible. Meanwhile I tried something different: I patched HTMLTALParser.py and ZopePageTemplate/__init__.py to recognice namespaces. One may pass a dict of namespaces to PageTemplate(). If a tag's prefix belongs to a namespace listed here, the tag get patched into somthing like <metal:block tal:define="year string:'1999'" tal:content="python:namspaces['hg'].copyright(year=year)" /> Quite a hack, but works :-) Do you want to get the patch? Never the less I would prefere a really expantable solution.
but most of them are not integrated with Zope.
It seams as if I have bad luck on this topic. Regards +++hartmut -- | Hartmut Goebel | We build the crazy compilers | | h.goebel@crazy-compilers.com | Compiler Manufacturer |
