tgext.less is based on tgext.scss by Alessandro Molina and is under the same license (MIT).

Enabling tgext.less

Using tgext.less is really simple, you edit your config/middeware.py and just after the #Wrap your base TurboGears 2 application with custom middleware here comment wrap app with LESSMiddleware:

from tgext.less import LESSMiddleware

make_base_app = base_config.setup_tg_wsgi_app(load_environment)

def make_app(global_conf, full_stack=True, **app_conf):
    app = make_base_app(global_conf, full_stack=True, **app_conf)

    # Wrap your base TurboGears 2 application with custom middleware here
    app = LESSMiddleware(app)

    return app

Now you just have to put your .less files inside public/css and they will be served as CSS.
