A small Flask extension that makes it easy to use Stylus with your Flask application.
pip install flask-stylus2css
You can activate it by calling the stylus2css function with your Flask app as a parameter:
from flaskext.stylus2css import stylus2css
stylus2css(app, css_folder='css', stylus_folder='src/stylus')
This will intercept the request to css_folder and compile de file if is necesary using the files from stylus_folder.
When you deploy your app you might not want to accept the overhead of checking the modification time of your .styl and .css files on each request. A simple way to avoid this is wrapping the stylus2css call in an if statement:
if app.debug:
from flaskext.stylus2css import stylus2css
stylus2css(app)
If you do this you’ll be responsible for rendering the .styl files into .css when you deploy in non-debug mode to your production server.
