Signals with coroutines!

Project description

AsyncBlink is a small extention to Blinker and enables you to use coroutines as receivers for your signals.


Installation is simple, via pip:

   $ pip install asyncblink


Usage is simple, too. Create a signal, connect some receivers to it and then use the send() method to trigger all receivers

from asyncblink import signal
my_signal = signal('nice-signal')

async def coro_receiver(sender, **kwargs):
    # an expensive io operation here
    return 'done'

def receiver(sender):
    return 'ok'


Other than that, AsyncBlink's usage is the same as Blinker, Take a look at the `Blinker documentation for further information.

Why this still exists?

Blinker now supports coroutines via signal.async_send, so why asyncblink is still alive?

The blinker's implementation awaits for coroutines and it is not what I want so asyncblink schedules the coroutine and returns a task.
