If you are looking for SASS and Rails, this port works great. https://github.com/thomas-mcdonald/bootstrap-sass

Yup, and we'll be working with these folks make this more official shortly. Stay tuned!

That's great, there are a couple of sass ports for 2 and it was time consuming evaluating them so an officially blessed port would be great.

For those of us integrating it with web app where we use semantic class names that we want to map to template styles, it would help if there were sass versions that create no concrete styles, just mixins and placeholder styles, so that we can extend our classes with bootstrap ones without inheriting styles on elements where we don't want the bootstrap style. e.g. I wanted the .nav-tabs style but already had my own .nav styling.

Do you have any plans to make it possible to extend from bootstrap in this way?

I might try this when I get home - I'm new to Ruby/RoR and I had a hell of a time getting the twitter-bootstrap-rails gem and it's dependencies installed on my windows machine and just went with Foundation.

I've been using this port without issue: https://github.com/jlong/sass-twitter-bootstrap/tree/3.0.0-w...
