Folks, I wrote a poker server in Erlang (link in signature) and I'm learning Haskell with an eye towards using it with Erlang. Erlang would take care of the overall control, etc. whereas Haskell would take care of the rest. I'm stuck with the basics I'm afraid and Haskell hackers don't seem to be active this weekend ;). I'm trying to write the poker server in Haskell to compare against my other implementations, specifically the Erlang one. The server talks a binary protocol. A packet notifying the player that a game has started looks like this: 0 1 5 7 +----+-----+-----+ | 24 | GID | Seq | +----+-----+-----+ I get a message from Erlang once data arrives over TCP and the message is a {tcp, Socket, Bin} tuple where Bin is binary data. I can easily extract what I need using Erlang binary pattern matching: read(<<24, GID:32, Seq:16>>) -> {24, GID, Seq}. My code shoots tuples like {24, GID, Seq} back and forth and all is fine. How would I do this in Haskell, though? Some folks have kindly supplied me with references to the various binary I/O packages and some server examples. I'm wondering, though, if someone would be kind enough to show how a packet like above could be sent and retrieved using Haskell sockets. I think this would serve as an excellent example to be posted at the Haskell Wiki. I also think that Haskell has a lot of interesting features that could well simplify my poker coding. I just need a little help to get started. Thanks, Joel -- http://wagerlabs.com/tech
