# 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
1.3 (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.
1.0 (March 28, 2010)
- Python 3.x compatibility
0.9 (February 26, 2010)
- Sphinx docs, project website
- Added ``with a_signal.temporarily_connected_to(receiver): ...`` support
