Hello,
I'm looking for tips on the simplest way to handle #include
directives in a file to be parsed by ANTLR. I've seen the advice
that it's not a problem that ANTLR is well-suited to solve, but I'm
not sure what's the best way to go about this. I can easily write a
preprocessor that just inserts the contents of the included file in
the stream that's handed to the lexer, but then I don't see a good
way to provide line numbers/filenames in error messages.
It seems like there ought to be a simple way to deal with this
general problem; am I missing it?
Thanks,
Bill
