I'm relatively new to TextMate, only been using it for a few weeks, and I have decided it quite possibly the best way for me to develop my games, programs and websites in. Unfortunately it when I downloaded it did not do any BlitzMax, which is one of the main IDE's I use. I began to look around and I couldn't find one anywhere.
Anyway I began to develop my own, and I have just today gotten it to a working stage. There are still limitations in it, which I'm looking in to on how to correct.
Anyway, here is a link to a post on my blog about it, and where you can download it. I hope people like it, as it has taken quite a bit doing and learning of TextMate's bundle system.
