Thanks Thomas! Used your gem in a project recently when we migrated an older app from a Theme Forest layout to Twitter Bootstrap. It wasn't immediately obvious which gem was the best, since it looks like a few people set out to do the same thing, but yours was the only one that was up-to-date and easy to install. We've also been getting great mileage from rails_admin, which uses your gem as well. Thanks for doing this and sticking with it!
I've been wanting to use Bootstrap with some other CSS syntaxes for awhile, and I was wondering how you manage the conversion from less to scss and stay up to date with the latest Bootstrap changes?
In general I wait until the new version is merged into master, and I use GitHub's compare view to see all the changes between the latest version and the previous one, which I keep open on one screen and go through each file updating the bits that have changed. For the Javascripts I just copy the whole folder over, since I don't fiddle with those.
The main exception to this was for 2.0, which had a separate branch for a while so that people could still use bootstrap-sass while updating their application to the new syntax. When 2.0 was merged into master, since it had been under such heavy development I reconverted the entire codebase.
There are a few quirks with the conversion from Less to SCSS, but these tend to be few and far between, and are usually down to me missing a variable somewhere. The main one is the use of namespaced mixins[1]. SCSS doesn't support this, so I have to prefix/suffix the namespace to each mixin within the namespace. Aside from that, and method names/variable notation, there (appears to be, can't speak authoritatively since I haven't really used Less) little difference between the two.
