[Zope3-checkins] CVS: Zope3/src/zope/app/interfaces - interpreter.py:1.2 size.py:1.5

Thu Aug 21 11:19:54 EDT 2003

Update of /cvs-repository/Zope3/src/zope/app/interfaces
In directory cvs.zope.org:/tmp/cvs-serv8485/src/zope/app/interfaces

Modified Files:
	size.py 
Added Files:
	interpreter.py 
Log Message:
Final HEAD checkin of "Inline Code Support in TAL". For detailed messages 
during the development, see "srichter-inlinepython-branch". I tested the 
code with both, Python 2.2.3 and Python 2.3 and all works fine.

Here an example of what you can do:

  <script type="text/server-python">
    print "Hello World!"
  </script>

and

 <p tal:script="text/server-python">
   print "Hello World!"
 </p>

A more elaborate example would be:

<html><body>
  <script type="text/server-python">
    global x
    x = "Hello World!"
  </script>
  <b tal:content="x" />
</body></html>

This support is currently only available in "Templated Pages" after you 
activate the hook using the "Inline Code" screen.
