- # 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
