calculator example issue

[Mike Arbelaez]

Hello,

I'm excited to try out pulsar and was running through the first example which is the calculator. When i follow the instructions i'm not seeing the return pong but rather the coroutine object.

I have the server running in one terminal and I'm using the REPL in another terminal to do the commands below.

>>> from pulsar.apps import rpc

>>> p = rpc.JsonProxy('http://127.0.0.1:8060')

>>> p.ping()

<coroutine object _call at 0x108057678>

>>> p.calc.add(3,4)

<coroutine object _call at 0x10809e258>

Is there something I'm doing wrong?

The rpc client is asynchronous and it returns a coroutine.

To use it in the python shell you need to explicitly call the event loop "run_until_complete" method

p._loop.run_until_complete(p.calc.add(3,4))

I need to update the documentation :-(
