[TxMt] language definition regexp question

Hi Allan,

Thanks very much for the response. I tried it and fiddled with it a
lot but I couldn't get this working.

If I try the above rule alone (no other matches in the whole language
file) it doesn't seem to work as a way to capture the "this" and
"parent" words. I can't style them with the following in the
preferences scope selector.

"variable.language.this-or-parent.js".

Did the above work for you?

WOW! it is possible to subtract scopes? That is very cool!

By the way, I just spent two days trying to learn VIM for a work
situation. What a waste of my time. I think it would take me a year of
plugin programming to get VIM to a state of productivity not quite
matching Textmate. Textmate is a far better solution.

Thanks,
Peter
