Project description

curlylint

PyPI Travis Total alerts Language grade: Python

{{ 🎀}} Prototype linter for Jinja and Django templates, forked from jinjalint.

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, however 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. Curlylint doesn’t work with Python 2. Install it with pip install curlylint (or pip3 install curlylint depending on how pip is called on your system), then run it with:

curlylint template-directory/

…or:

curlylint some-file.html some-other-file.html

This is a work in progress. Feel free to contribute :upside_down_face:

CLI flags

--verbose

Turns on verbose mode. This makes it easier to troubleshoot what configuration is used, and what files are being linted.

curlylint --verbose template-directory/

--parse-only

Don’t lint, check for syntax errors and exit.

curlylint --parse-only template-directory/

Configuration

Curlylint supports defining a config file with the flag --config. Here is an example config file with the available options:

# Specify additional Jinja elements which can wrap HTML here. You
# don't need to specify simple elements which can't wrap anything like
# {% extends %} or {% include %}.
# Default: [].
jinja_custom_elements_names = [
    ('cache', 'endcache'),
    ('captureas', 'endcaptureas'),
    # ('for', 'else', 'empty', 'endfor'),
]

# How many spaces to use when checking indentation.
# Default: 4
indent_size = 4

This config file can then be used with:

curlylint --config example_config.py template-directory/

Usage with pre-commit git hooks framework

Add to your .pre-commit-config.yaml:

- repo: https://github.com/thibaudcolas/curlylint
  rev: "" # select a tag / sha to point at
  hooks:
    - id: curlylint

Make sure to fill in the rev with a valid revision.

Note: by default this configuration will only match .jinja and .jinja2 files. To match by regex pattern instead, override types and files as follows:

- id: curlylint
  types: [file] # restore the default `types` matching
  files: \.(html|sls)$
