[TxMt] Storing variables on a window by window basis

Hi all,

I'm new to writing TextMate bundles so I was wondering if someone could give me some pointers here.

I'm trying to store information from the output a bundle command against the current file. The idea is that this could then be retrieved by another bundle command run latter.

This information doesn't need to be persistently stored, it's only used during editing so if I can I'd prefer not to litter the file system with these small files.

Ideally, I'd like to do something like:

$MY_VAR = "some value or other"

Any of how to do this or a flat answer of you can't at the current time would be gratefully received.

Cheers, Sean.
