A signal one to one event
Slinker provide a single one to one event, we call it a link.
A link can only have a single sender and a single reciver.
The source code is locate at github .
Link receiver can subscribe to specific link. A reciver function required a sender argument, and a keyworld argument which is optional.
>>> from slinker import Namespace >>> links = Namespace() >>> started = links.link('round-started') >>> def each(round): ... print "Round %s!" % round ... >>> started.connect(each) >>> for round in range(1, 4): ... started.send(round) ... Round 1! Round 2! Round 3!
Here provide a decorator receiver which can be used for connect. Because a link can only have one reciever. If you want to connect to another receiver, you must disconnect the formly receiver.
>>> started.disconnect(each) >>> from slinker import receiver >>> @receiver(started) def test(sender, **kwargs): ... return sender >>> func, result = started.send('hello') >>> func == test ... True >>> result == 'hello' ... True
