[Zope3-checkins] CVS: Zope3/src/zope/app/pagetemplate - meta.zcml:1.1 metaconfigure.py:1.1 talesapi.py:1.1 configure.zcml:1.3

[Matt Hamilton]

Update of /cvs-repository/Zope3/src/zope/app/pagetemplate
In directory cvs.zope.org:/tmp/cvs-serv2345/src/zope/app/pagetemplate

Modified Files:
	configure.zcml 
Added Files:
	meta.zcml metaconfigure.py talesapi.py 
Log Message:
Extended TALES namespace functionality to Zope3.  You can now use 
TALES expressions such as foo/zope:title within ZPT.

Currently only a single function 'title' has been created within
talesapi.py, now we need to work out which functionality we want to 
expose ;-)  Probably look through the ZQR and places like that.

       <description>Define a new tales namespace
     
       A namespace is defined by providing a prefix and an interface. A
       handler for the namespace will be obtained by looking up an adapter for the
       given interface.
       </description>

       <attribute name="prefix" required="yes">
         <description>The prefix used in tales expressions. 

         For example, if the prefix is "dc", then a tales expression would
         look like: ``foo/bar/dc:title``.
         </description>
       </attribute>

       <attribute name="interface" required="yes">
         <description>The namespace interface

         This is an interface that the namespace must provide.
         we'll get the namespace by getting an adapter for this interface.
         </description>
