A PHP Django Template Language Rip-Off for the Zend_Framework

This is the first alpha/beta version of a PHP Template Engine
implementing the Django Template Engine as used by the
Python Framework Django. It can be also be used
as Standalone or within the Zend Framework View Interface.

Development TODOS
================================================
1. Escaping should be Charset/Encoding aware. Currently
htmlspecialchars is used deep inside the engine, which cannot be
configured.

2. it was reported that multiple inheritence templates don't work.

3. a general refactoring to allow intermediate parsing into PHP code
should be thought off to optimize the currently VERY VERY slow performance.

Features
================================================

It replicates almost all tags and filters currently and
passes many unit tests for all parts of the engine as described
under:

http://www.djangoproject.com/documentation/templates/

An extension has been implemented to allow the possibilty
to serve parts of the template by the Client via Javascript
and the DojoX DTL implementation. This works as follows:

{% ajax "csshook" "url" %}
..various dtl language statements here...
{% endajax %}

Puts the inner ajax block onto a Client DTL Stack which can then
be rendered as DojoX DTL Requests using:

{% dtlstack %}

The template will be hooked into "csshook" using context data
that has to be served from "url" via JSON.

Using Calypso DTL
================

A full fleged demo is bundled with this release. See it for more information.

Currently Calypso_View_Dtl can only function with an Autoloading component
like the Zend_Loader since no require or includes are made throughout the
scripts. The component has to reside in the include path (use set_include_path()):

require_once "Zend/Loader.php";
Zend_Loader::registerAutoload();

$view = new Calypso_View_Dtl();
$view->assign('var', $var);
$view->var = $var;
echo $view->render('dtltemplate.tpl');
