You should know by now that I’m a huge fan of Hammer For Mac. I couldn’t and wouldn’t start a project without it as I’d miss its variables and partials and includes too much. I like Hammer so much I moved from LESS to Sass because of it.
If you’re a CodeKit user — and many are — you can get some of Hammer’s functionality in that too. I haven’t had the need to try CodeKit and The Kit Language myself yet, so I’d be keen to know if you have and what you think? Let me know on Twitter @malarkey.
