Hans-Jörg, thanks for our explanations.
Ok, I understand now that I should only use it for private purposes.
Regarding to your Erlang enhancements: What do you want to improve by using TMTOOLS? Maybe, there are other ways.
This is what I would use TMTOOLS for:
1) after having parsed compiler error output, highlight the region of the error and move caret there 2) source code manipulation such as refactoring, based on AST
I am new to textmate, there might be other ways to achieve this ..
otherwise I am hoping Allan is reading this and soon providing a stable API, then I could write the Erlang integration natively (but that is a problem of it's own, so far I have only written native Erlang integrations in C)
