Code example

The callback listener takes 2 arguments, the name of the signal, and the argument that was emitted

The listen function is called synchronously, but the callback listener should be a coroutine or future

The emit function is a coroutine

import asyncio
from aio.signals import Signals

@asyncio.coroutine
def listener(signal, message):
    print(message)

signals = Signals()
signals.listen("my-signal", listener)

loop = asyncio.get_event_loop()
loop.run_until_complete(
    signals.emit("my-signal", 'BOOM!'))
