Hello everyone,
I would just like to ask if there is a way of ignoring sections of input
language. Something like:
i want to recognize these sentences only and ignore everything that
doesn't look like them.
I tried:
sentence: macro | ~macro
but antlr gives me an error: unexpected token: macro (quite
understandable i guess, since is not a token but a syntactic rule).
So, summing up: can i tell antlr i want to recognize some specific
syntactic rules and ignore everyother single stuff that doesn't match??
Maybe something like disabling errors (not that i like this alternative
very much).
Best regards,
Bahr.
