[antlr-interest] Token stream filter

[Anthony Youngman]

This sounds like it should be very easy, but I can't see how to do it
...

I want to filter the token stream coming out of the lexer (and I can't
see how to do it using the lexer's filter - can I do the same thing in
the parser?). Anyways, I want to match the following sequence

(newline | semi) ("rem" | "*" | "!" ) ~( "=" | "(" ) ({greedy=false} .)
newline)

eating everything EXCEPT the newline, which needs to be passed through
to the parser. Note also, that while "*" and "!" are tokens, "rem" is an
ident. Of course, if I need "rem" to be a token, presumably if this rule
fails I can convert it back to an ident?

Or do I need to write my own token stream to do this (if so, where do I
look for an example?)

Cheers,
Wol
