No pull socket?

I try to use a pull socket with ezmq, but I get an error saying there is an error in the socket_type.

#! /usr/bin/env escript
%%! -pa deps/ezmq/ebin -Wall debug verbose

main(_) ->
    {ok, Socket} = ezmq:start([{type, pull}]),
    ezmq:connect(Socket, {127, 0, 0, 1}, 5558, []),
    loop(Socket, 0),

    ok = ezmq:close(Socket).

loop(_Socket, 10) ->
    ok;

loop(Socket, N) ->
    {ok, Request} = ezmq:recv(Socket),
    io:format("Received '~s' ~w~n", [Request, N]),
    loop(Socket, N+1).

escript: exception error: no match of right hand side value {error,invalid_opts}

Only req, rep, router, dealer, sub and pub are implemented at the moment.

Locking at the zeromq docs, it seems that dealer is the closest similar behavior. Could you use that as temporary alternative?

BTW: building ezmq_socket_push.erl and ezmq_socket_pull.erl wouldn't take much, but my dev-system is currently down :-(

Yes, you can use dealer as substitute for pull or push. Dealer is in fact identical to the two combined (bidirectional, where pull and push restrict flow to one direction each).

Excuse me guys, I couldn't manage to correctly make dealer sends to a pull socket (I'm still quite new to Erlang), would you give me a clue on how to make that work ? :)

Dealer can send to dealer, it's exactly the same (except biirectional).

Thanks for the hint Pieter! my problem was on understanding the way to send multiple frames on the ezmq:send/2 function. I got it, and now I'm using a combination of dealer-router, sending data as ezmq:send(Socket, [<<"some-id","","message-here">>])..
