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

Install

Installation is simple, via pip:

   $ pip install asyncblink

Usage

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'

my_signal.connect(coro_receiver)
my_signal.connect(receiver)
my_signal.send('some-sender')

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.
