PySignalsEx is a Python signal dispatcher, extracted from the Django framework, and extended to provide a special "capture all" signal called any_signal. This special signal is useful for instrumentation, logging, auditing, debugging, etc.
For a version that is true to Django, without this extension, see https://github.com/theojulienne/PySignals
Example
PySignalsEx is originally extracted from the Django framework, therefore the best place to get documentation is from the Django Signals Documentation.
Additionally, PySignalsEx provides a special signal called 'any_signal'. When you listen for this signal, your listener will be notified of all signals sent in your application. You listen for any_signal as you would for any other.
from pysignalsex import Signal, receiver, any_signal
@receiver(any_signal)
def mylistener(sender, **kwargs):
print "kwargs:", kwargs
if kwargs['signal'] == mysignal:
print "mysignal"
if kwargs['signal'] == myothersignal:
print "myothersignal"
mysignal = Signal(providing_args=['myarg'])
myothersignal = Signal()
mysignal.send(sender='sender1', myarg='myval')
myothersignal.send(sender='sender2')
