A small Flask extension that makes it easy to use Sass (SCSS) with your Flask application.
This was forked as we use it in our projects and wanted to make sure a copy was available if the original was ever removed.
The original creator adapted from https://github.com/weapp/flask-coffee2js to perform the same task for sass
pip install git+https://github.com/openbridge/flask-sass.git#egg=flask-sass
You can activate it by calling the sass function with your Flask app as a parameter:
Your output dir should be located in the static directory.
from flaskext.sass import sass
sass(app, input_dir='assets/scss', output_dir='css')
This will intercept the request for output_dir/*.css and compile the file if it is
necesary using the files from input_dir/*.scss.
When you deploy your app you might not want to accept the overhead of checking
the modification time of your .scss and .css files on each request. A
simple way to avoid this is wrapping the sass call in an if statement:
if app.debug:
from flaskext.sass import sass
sass(app)
If you do this you'll be responsible for rendering the .scss files into
.css when you deploy in non-debug mode to your production server.
