module network

gamnit :: network

Easy client/server logic for games and simple distributed applications

Both client and server can be used separately or together by importing network. Use both modules to create an program that discover local servers or create one if none is found:

redef fun handshake_app_name do return "network_test"

# Discover local servers
var servers = discover_local_servers
if servers.not_empty then
    # Try to connect to the first local server
    var server_info = servers.first
    var server = new RemoteServer(server_info)

    if not server.connect then
        print_error "Failed to connect to {server_info.address}:{server_info.port}"
    else if not server.handshake then
        print_error "Failed handshake with {server_info.address}:{server_info.port}"
    else
        # Connected!
        print "Connected to {server_info.address}:{server_info.port}"

        # Write something and close connection
        server.writer.serialize "hello server"
        server.socket.as(not null).close
    end
else
    # Create a local server
    var connect_port = 33729
    print "Launching server: connect on {connect_port}, discovery on {discovery_port}"
    var server = new Server(connect_port)

    # Don't loop if testing
    if "NIT_TESTING".environ == "true" then exit 0

    loop
        # Respond to discovery requests
        server.answer_discovery_requests

        # Accept new clients
        var new_clients = server.accept_clients
        for client in new_clients do
            # Read something and close connection
            assert client.reader.deserialize == "hello server"
            client.socket.close
        end
    end
end
