[rabbitmq-discuss] AMQP Erlang client

[Michael Vierling]

Has the Erlang AMQP client code changed recently?  We are attempting to get the metronome plugin to work.  However the following code seems no longer to work:

init([]) ->
  Connection = amqp_connection:start_direct(),
  Channel = amqp_connection:open_channel(Connection),
  amqp_channel:call(Channel, #'exchange.declare'{exchange = <<"metronome">>,
                                                 type = <<"topic">>}),

In the current code, the start_direct function no longer exists.  So I've replaced it with start.

init([]) ->
  Connection = amqp_connection:start(direct),
  Channel = amqp_connection:open_channel(Connection),
  amqp_channel:call(Channel, #'exchange.declare'{exchange = <<"metronome">>,
                                                 type = <<"topic">>}),

However it still doesn't work.

(rabbit at rabbit9)6> Channel = amqp_connection:open_channel(Connection).

     in call from amqp_gen_connection:open_channel/2

Any ideas?
