Oh wow. There's another person who uses TextMate! Hi. I'm not alone ;-)
I've been in TextMate about as long. And I love the product to death. I just want it to stop eating itself. And I really, really wish Allan would treat it seriously. He built a beautiful thing and then seemingly gave up. Right now the publicly checked in code on Github can't be compiled (errors in Rave).
Given that I use Ruby and MarkDown only (maybe some yaml), I can't see the syntax highlighting being the issue since TextMate internally is so much Ruby.
VI is also my adjunct.
I try Sublime every few years and it never feels right.
VS Code - Oy. JavaScript is NOT a proper way to write an editor.
Not an IDE fan.
Eclipse. Not Mac like.
BBEdit -- interesting; I'll add it to the list.
