cloud-haskell-socket-test

A "chat" server using the distributed-process family of libraries. It really just sends bytestreams from each client to all other clients. Not very smart!

Install

stack build
stack exec cloud-haskell-socket-test-exe

Use

Connect and send/receive bytes to/from other clients:

nc localhost 4444

How it works

• Single thread accepting new connections, spawns a new local process on client connect.
• Client thread is actually a pair of processes, both have an IORef containing Pids of all other processes:
  1. Reader: reads msgs from client, and broadcasts to other processes
  2. Writer: receives raw strings from other clients and writes to socket
