Hi,
I started using Data.Binary yesterday for a project and it's nice. I'm
not sure it's possible, but perhaps you could switch tools along the
way:
- Parse the ASCII bit with Parsec ;
- Give the remaining ByteString to Data.Binary for the binary part ;
- Switch back and forth as required.

Hi, does anyone here know their way around in Parsec? I'm trying to parse a file which contains some binary parts too. I have been using Parsec 3.0.1 to parse the first ASCII part, but all the parsers are returning Char type tokens, so it would not work with the binary parts .. is there any way to do this? I am using Text.Parsec.ByteString.Lazy.
Note that I'm new to Haskell and Parsec, and doing this within a small project that I basically do to get a grip on Haskell (and Parsec, because it appears to be really nifty and I want to learn more about it).
Thanks for any hints, Christian
Parsing binary parts of a file is not inherently a problem. A parser can return any type; different parsers in your application will likely return different types.
If you include some code we'll be able to help you more specifically.

You're right, I probably used the wrong words .. I meant that apparently the tokens Parsec uses are of type Char, and I would actually at some point like to continue parsing, but using different tokens. Sorry if I still got it wrong, I'm new :) I can post some code later, as I don't have it here right now.
Cheers, Christian
