Note: This is a fork of [jek/blinker](https://github.com/jek/blinker)!
There didn’t seem to be any activity anymore on the original repo, and the latest changes on
master weren’t officially released. So I forked the repo, merged a couple of important pull
requests, and released a new version to PyPI under the name
[blinker-alt](https://pypi.python.org/pypi/blinker-alt).
# Blinker
Blinker provides a fast dispatching system that allows any number of
interested parties to subscribe to events, or “signals”.
Signal receivers can subscribe to specific senders or receive signals
sent by any sender.

>>> from blinker import signal
>>> started = signal('round-started')
>>> def each(round):
... print "Round %s!" % round
...
>>> started.connect(each)

>>> def round_two(round):
... print "This is round two."
...
>>> started.connect(round_two, sender=2)

>>> for round in range(1, 4):
... started.send(round)
...
Round 1!
Round 2!
This is round two.
Round 3!


See the [Blinker documentation](https://pythonhosted.org/blinker/) for more information.
## Requirements
Blinker requires Python 2.4 or higher, Python 3.0 or higher, or Jython 2.5 or higher.
## Changelog Summary
1.5 (October 15, 2017)

Lower baseline cost of no-op signal send() & optional -O speedup.
Verified Python 3.6 support (no changes needed).
Verified Python 3.5 support (no changes needed).

1.4 (July 23, 2015)

Verified Python 3.4 support (no changes needed)
Additional bookkeeping cleanup for non-ANY connections at disconnect
time.
Added Signal._cleanup_bookeeping() to prune stale bookkeeping on
demand

1.3 (July 3, 2013)


The global signal stash behind blinker.signal() is now backed by a
regular name-to-Signal dictionary. Previously, weak references were
held in the mapping and ephemeral usage in code like
signal('foo').connect(...) could have surprising program behavior
depending on import order of modules.
blinker.Namespace is now built on a regular dict. Use
blinker.WeakNamespace for the older, weak-referencing behavior.
Signal.connect(‘text-sender’) uses an alternate hashing strategy to
avoid sharp edges in text identity.


1.2 (October 26, 2011)


Added Signal.receiver_connected and Signal.receiver_disconnected
per-Signal signals.
Deprecated the global ‘receiver_connected’ signal.
Verified Python 3.2 support (no changes needed!)


1.1 (July 21, 2010)


Added @signal.connect_via(sender) decorator
Added signal.connected_to shorthand name for the
temporarily_connected_to context manager.

Python 3.x compatibility


0.9 (February 26, 2010)


Sphinx docs, project website
Added with a_signal.temporarily_connected_to(receiver): ... support
