Hi, May be it's a frequently asked question, but I have been unable to find my way in the parsec-3.0.0 library when trying to write a small parser with Parsec that could work with ByteStrings. I mean, there is the Text.Parsec.ByteString module which allows to parse a file using ByteStrings, but the parser one needs to write must parse ByteStrings instead of Strings (that is, something like having a "Parsec Bytestring ()" type, unless I'm completely misunderstanding the situation). My problem is that I do not manage to write primitive parsing combinators (like string, satisfy, letter, etc.) to define my language's tokens. I'm surely missing some primitive somewhere (may be the Text.Parsec.Prim.token, though I do not really manage to use it). Thanks in advance, F.
