Re: [Haskell-beginners] Bytestring question

Thanks for your reply. Attoparsec seems to be the perfect tool for the job and i will ultimately try to implement my converter utilizing it. But i also installed bytestring-lexing and will try this out, just to see if i can gain some performance when eliminating the suboptimal reads / unpacks. Thanks for the tip! Shouldn't the type better be parseFile :: Handle -> StlLineType -> [L.ByteString] -> IO () Yes, there really is no reason for using a tuple. I'll also eliminate the usage of (!!) and function calls where pattern matching is possible.
