[Freeswitch-users] Re-2: Ruby and ESL help

[Diego Viola]

It seems like EM (EventMachine) can't be used with ESL.

16:41 < diegoviola> thedonvaughn: i see, so ESL itself can't be used with EM?
16:41 < wyhaines> You can't just hand the socket from EM to ESL.
16:42 < thedonvaughn> prolly not
16:42 < thedonvaughn> and if tmm1 doesn't know how, then i'm going to say no :()
16:42 < wyhaines> EM will invoke callbacks on your protocol object
when data comes in (receive_data), and goes out (send_data).  When the
connection is
                  closed (unbind), etc....
16:43 < wyhaines> To use ESL, you'd have collect data form
receive_data into a buffer, and pass that into ESL, and ESL would have
to support being used in
                  that way.
16:43 < diegoviola> ok then i will just use FSR
16:43 < wyhaines> However, it looks like ESL wants to control the
socket, which won't work because EM is already controlling the socket.

That conversation was in #eventmachine.
