f.when(:echo, String) do |text|
f.send!(:result, "You said: #{text}")
f.receive_loop
end
end
== USAGE (Erlang side):
-module(echo).
-export([test/0]).
test() ->
Cmd = "ruby echo.rb",
Port = open_port({spawn, Cmd}, [{packet, 4}, use_stdio, exit_status, binary]),
Payload = term_to_binary({echo, <<"hello world!">>}),
port_command(Port, Payload),
receive
{Port, {data, Data}} ->
{result, Text} = binary_to_term(Data),
io:format("~p~n", [Text])
