Re: [Haskell-cafe] Need programming advice for Network Protocol Parsing

 My question is in regard which parser to use for the servers responses. I'm
 quite familiar with parsec (2.x) but I'm not sure if it's the right choice
 for this. The code would necessarily constantly be switching between
 checking for input, interpreting and then responding.

Attoparsec is kind of made for this:

Re: [Haskell-cafe] Need programming advice for Network Protocol Parsing

I'm occasionally working on making a friendly yet performant library that
simultaneously builds parsers and generators, but it's non-trivial. If you
want to see the general idea, there's a Functional Pearl on pickler
combinators from a few years back that you can probably play with.

But for a real network protocol that you need to implement today, I'd go
with attoparsec or Data.Binary.

 Hi all,

 I'd like to write a client app that communicates with a server over TCP/IP.

 My question is in regard which parser to use for the servers responses. I'm
 quite familiar with parsec (2.x) but I'm not sure if it's the right choice
 for this. The code would necessarily constantly be switching between
 checking for input, interpreting and then responding.

 Any suggestions?

 Günther
