This PR adds the ability to extend templates via inheritance. Similar to what's available in Jinja.

Extending a template allows overriding "blocks" in the base template. This helps supporting more complex templating scenarios when developing web applications.

base.ede

<!doctype html>
{% block head %}
<title>{% block title %}{% endblock %}</title>
{% endblock %}
{% block body %}{% endblock %}

child.ede

{% extends "base.ede" %}
{% block title %}Index{% endblock %}
{% block head %}
  {{ super }}
  <style type="text/css">
    .important { color: #336699; }
  </style>
{% endblock %}
{% block body %}
  <h1>Index</h1>
  <p class="important">
    Welcome to my awesome homepage.
  </p>
{% endblock %}

Additionally,

  • there's a patch in here that introduces a "set" block that allows setting a variable to a template value.
  • with the notion of blocks it's very easy now to support rendering "template fragments" the HTMX way. Easy to add later.

If you are interested in these changes I can do refactoring if required.
