I’m pleased to announce that you can now get Sass rolled into _s by simply checking the box on Underscores.me. The community has driven this change through pull requests and forks.
It’s taken a little while, but we wanted to do it right. As with the rest of Underscores, we wanted to keep it as simple as possible, offering any extra scripting with a checkbox option rather than imposing it on all developers. Not everyone compiles or uses Sass the same, so _s shouldn’t force anyone to follow one path or another. In this sense, the Sass provided takes a pure approach, not requiring Compass or any other scripts.
Worth noting along with this addition is that the Github version of _s is now purely for development. We strongly recommend only using Underscores.me to download _s, going forward.
Just like with _s itself, the Sass it uses will probably change and evolve with time. What is in place now is a structure, a starting point. Any issues, or requests can be posted on Github, and you can even roll your own using a fork. Just like _s is your theme’s starting point, you can take the Sass in any direction you want.
I hope you are excited as I am to see Sass in _s! I’d like to thank the following people – without them this would not have been possible. As this was a Github project, here are their Github usernames: @gregrickaby @bradp @hugobaeta @obenland @sabreuse @MichaelArestad @jacklenox and myself. I look forward to seeing what things people build and where they take Sass in _s.
