There’s some visual and conceptual overlap between TextMate and Sublime Text, with both offering a quite similar feature-set. However, TextMate for a long time had pride of place on the Mac, in part through being designed specifically for the platform. However, a major update long languished in development hell, hitting the app’s reputation.
There’s now a 2.0 preview available for download, and the source has been released for end users to tinker with. For the time being, it’s also free to use, although you can buy a license if you wish. That said, we’d urge caution with this one, because although it’s still a great app, who knows when a final 2.0 will appear?
