[antlr-interest] ANTLR Eclipse plugin newsgroup

[Scott Stanchfield]

oh, you're right -- I was thinking about the "grammar only" page in the
editor. I think (but I'm not sure) that the outline view uses an antlr
scanner, though.

(I didn't mess with that area much)

Thanks for the correction!

It doesn't do on-the-fly markers (yet), but it does add markers after saving
the file based on the java compile and the antlr run.

I'll take a look at adding some code like that and see what happens...

Thanks,
-- Scott
