Zope Page Template engine based on Chameleon
Project description
Overview
========
This package provides a fast Zope Page Template implementation based
on the Chameleon template compiler. It's largely compatible with
``zope.pagetemplate``.
Usage
-----
Load the package component configuration file (configure.zcml).
Performance
-----------
Casual benchmarks pegs it 16x more performant than the reference
implementations for Zope TAL and Genshi (using Python-expressions).
Compiler notes
--------------
The compiler is largely compatible with the reference
implementation. The TAL implementation is based on the 1.4 language
specification.
Some notable changes:
1. Tuple unpacking is allowed when defining variables:
tal:define="(a, b, c) [1, 2, 3]"
2. Generators are allowed in tal:repeat statements. Note that the
repeat variable is not available in this case.
tal:repeat="i <some generator>"
3. Attribute-access to dictionary entries is allowed in
Python-expressions, e.g.
dictionary.key
can be used instead of ``dictionary['key']``.
4. The default expression type is Python.
5. Genshi expression interpolation syntax is supported outside tags
and inside static attributes, e.g.
<span class="hello-
</span>

Development
-----------
If you want to use the code directly from trunk (recommended only for
development and testing usage), provide ``chameleon.zpt==dev`` as your
dependency.
The code is maintained in a subversion repository::
svn://svn.repoze.org/svn/chameleon.zpt
