This extension to jinja make it possible to close tags with just "end" instead of endif, endfor and so on. It can be mixed with normal end tags.
It also works with line statements.
from jinja2 import Environment
from jinja_simplesyntax import SimpleSyntaxExtension
env = Environment(
line_statement_prefix='%:'
extensions=[SimpleSyntaxExtension])
{% for i in range(10): %}
{% if i == 0 %}
First
{% else %}
{{ i }}
{% end %}
{% end %}
With line statements its also possible to use inline content like this:
%:block title | This is the title %:if True | Yes it's true
This becomes:
{% block title %}This is the title{% endblock %}
{% if True %}Yes it's true{% endif %}
