Macromate’s next generation Text Editor, TextMate 2, has been open sourced according to Macromate’s blog:
Today I am happy to announce that you can find the source for TextMate 2 on GitHub. I’ve always wanted to allow end-users to tinker with their environment, my ability to do this is what got me excited about programming in the first place, and it is why I created the bundles concept, but there are limits to how much a bundle can do, and with the still growing user base, I think the best move forward is to open source the program.
The source is licensed under the GPL 3, which will prevent someone from taking the source and forking to create a commercial product.
As a long time user of TextMate, I hope that this lights a fire under it’s development. However, open sourcing an app usually results in the app languishing in to oblivion. Hopefully, TextMate 2 will continue to be developed and survive.
