Cutesy checks HTML documents for consistency and best practices. It’s opinionated. It includes a set of rules, most of which can be fixed automatically.
Cutesy expects HTML5 files, with UTF-8 encoding.
Cutesy works with templating languages, such as Django Template Language or Ruby's ERB. These are handled during the "preprocessing" step. Because of this, Cutesy takes dynamic template tags into account for certain types of formatting (such as indentation) & some rules (such as balancing HTML tags).
Preprocessing is (or will be) supported for these templating languages:
- Django
- Jinja
- ERB
- Handlebars
- EJS
- Mustache
- Nunjucks
- Smarty
- Liquid
- Catch accidental errors.
- Enforce best practices.
- Code without worrying about formatting. Cutesy formats automatically.
- Improve code readability.
- Small diffs for easier code review.
Cutesy ensures that HTML documents contain consistent whitespace, follow best practices, and adhere to common conventions. In --fix mode, Cutesy turns this:
<!doctype html>
<html>
<head>
<title>Test Page</title>
</head>
<body>
<h1>Hello world! </h1>
{% if condition1 %}
<p>I love cookies.</p>
{% endif %}
<div class='someDiv'
id="theDiv" ></div >
</body>
</html>
…into this:
<!doctype html>
<html>
<head>
<title>Test Page</title>
</head>
<body>
<h1>Hello world! </h1>
{% if condition1 %}
<p>I love cookies.</p>
{% endif %}
<div id="theDiv" class="someDiv"></div>
</body>
</html>
See the full list of rules for more information.
Cutesy is written in Python. Install via PyPI:
pip install cutesy
Minimal usage:
cutesy some_file.html
Lint multiple files using a glob pattern:
cutesy "*.html"
cutesy "path/to/templates/**/*.html"
# etc…
Fix files automatically (recommended):
cutesy "*.html" --fix
Cutesy can check HTML fragments, or whole HTML documents. By default, Cutesy ignores files specifying a non-HTML5 doctype (anything other than <!doctype html>).
To assume (and enforce) that all matching files are HTML5, use the --check-doctype flag:
cutesy "*.html" --fix --check-doctype
To lint files written in a template language, such as the Django Template Language:
cutesy "*.html" --fix --preprocessor django
Other options:
--code: Process the code passed in as a string.--quiet: Don't print individual problems.--return-zero: Always exit with 0, even if unfixed problems remain.--version: Show the version and exit.--help: Show the CLI help and exit.
