Yeah, I'm thinking of a Cat-like class that would chunkify the data and check
for matches.
The main reason I would like to stick with a consistent grammar-based approach
is I have seen many instances in BioPerl where a parser is essentially
rewritten based on its purpose (full parsing, lazy par
I was going to pipe in and say that I wouldn't wait around for Cat,
I'd write something that reads chunks and then parses that. It'll be a
bit more code, but it'll work today. But I see you reached that
conclusion already. :)
Lately I've found myself writing more and more grammars that parse
