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
