jinjalint

A prototype linter which checks the indentation and the correctness of Jinja-like/HTML templates. Can fix issues.

It works with Django’s templates too, it should work with Twig and similar template languages. It should work fine with any kind of HTML 4 and 5, hovewer XHTML is not supported.

This linter parses both HTML and Jinja tags and will report mismatched tags and indentation errors:

<div>
    {% if something %}
    </div>
{% endif %}

<div>
    <span>
    </div>
</span>

  {% if something %}
 <div> not indented properly
      </div>
   {% endif %}

{% if something %}<a href="somewhere">{% endif %}
    <p>something</p>
{% if not something %}</a>{% endif %}

Usage

You need Python 3. Jinjalint doesn’t work with Python 2. Install it with pip install jinjalint (or pip3 install jinjalint depending on how pip is called on your system), then run it with:

$ jinjalint template-directory/

…or:

$ jinjalint some-file.html some-other-file.html
