Djula is a port of Python's Django template engine to Common Lisp.
Here a small example of a template::
{% extends "base.html" %}
{% block title %}Memberlist{% endblock %}
{% block content %}
<ul>
{% for user in users %}
<li><a href="{{ user.url }}">{{ user.username }}</a></li>
{% endfor %}
</ul>
{% endblock %}Application logic is for the controller but don't try to make the life for the template designer too hard by giving him too few functionality.
