# 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
