Cowsay Socket Server - Iteration 1

# Create the underlying socket server
@server = TCPServer.new(port)
puts "Listening on port #{@server.local_address.ip_port}"
end
def start
# TODO Currently this server can only accept one connection at at
# time. Do I want to change that so I can process multiple requests
# at once?
Socket.accept_loop(@server) do |connection|
handle(connection)
connection.close
end
end
def handle(connection)
# TODO Read is going to block until EOF. I need to use something
# different that will work without an EOF.
request = connection.read
# The current API will accept a message only from netcat. This
# message is what the cow will say. Soon I will add support for
# more features, like choosing your cow.
# TODO - Parse the request
# Write back the result of the hash operation
connection.write process(request)
end

# TODO This is just painfully naive. I'll use a different
# interface eventually.
