Lastest release
version 1.3 on Jul 5th, 2013
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!
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
