You should already have the "sending" code loaded up in a termainal window.
Open another one (be sure you are in the previously-created kanin-tutorials
directory), and Start up the REPL:
$ make repl-no-deps
Starting an LFE REPL ...
Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:4:4] [async-threads:10] ...
LFE Shell V6.2 (abort with ^G)
This will be your "receiving" terminal. Go ahead and start up the "receive" loop:
> (kt-receiving:receive)
[*] Waiting for messages. To exit press CTRL+C
Switch back over to your "sending" terminal, and fire off four calls of the
send function:
> (kt-sending:send)
[x] Sent message '"Hello, world!"'
ok
> (kt-sending:send)
[x] Sent message '"Hello, world!"'
ok
> (kt-sending:send)
[x] Sent message '"Hello, world!"'
ok
> (kt-sending:send)
[x] Sent message '"Hello, world!"'
ok
>
Switch back over to your "receiving" terminal, and you should see four messages indicating proper receipt:
[x] Received: <<"Hello, world!">>
[x] Received: <<"Hello, world!">>
[x] Received: <<"Hello, world!">>
[x] Received: <<"Hello, world!">>
That's it for the "Hello World" tutorial. The next tutorial is one on Work Queues
