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'
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.
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.
Source code is hosted on github.
