Using Haskell's Parsec to parse a ByteString

Question

I've managed to use Parsec to parse a String, but cannot manage to do the same with a ByteString.

How can I make Parsec work with ByteStrings without manually converting them to Strings?

I get the feeling this isn't hard to accomplish. Am I wrong? (I'm new to Haskell. ^^)

Thanks!

Answer 1

Just import the Parser type from Text.Parsec.ByteString or Text.Parsec.ByteString.Lazy, instead of from Text.Parsec.String.

Answer 2

Hi,

the answer actually depends on the version of Parsec you are using. If you are using version 3.0 or later then yes. For version 2.x.x I don't think you can.

Cheers

edit: The Parsec that STH suggest (Text.Parsec.ByteString) is actually version 3.0 the previous version 2.x.x is located in Text.ParserCombinators.Parsec.
