curlylint

curlylint

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

curlylint is a prototype linter for your templates – whether that’s Django’s templates, Jinja, Twig, or any other “curly braces” template language.

As of now, curlylint supports:

• Linting invalid template / HTML syntax due to mismatched tags – while template errors are easy enough to spot, it’s not rare for HTML issues to make their way to live sites.
• Indentation inconsistencies – Usage of tabs vs spaces, line breaks, indentation size.

In the future, we intend to support linting:

• Common accessibility issues in HTML – misuse of ARIA role, and making sure alternative text is used where appropriate.
• Common security issues – e.g. rel="noopener noreferrer", or preventing usage of HTTP URLs.
• General HTML code smells – duplicate attributes, invalid attributes, etc.
• More ideas welcome!

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
