Events 0.1.0

Bringing the elegance of C# EventHanlder to Python

The C# language provides a handy way to declare, subscribe to and fire events. Technically, an event is a “slot” where callback functions (event handlers) can be attached to - a process referred to as subscribing to an event. Here is a handy package that encapsulates the core to event subscription and event firing and feels like a “natural” part of the language.

>>> def something_changed(reason):
...     print "something changed because %s" % reason
...

>>> from events import Events
>>> events = Events()
>>> events.on_change += something_changed

Multiple callback functions can subscribe to the same event. When the event is fired, all attached event handlers are invoked in sequence. To fire the event, perform a call on the slot:

>>> events.on_change('it had to happen')
'something changed because it had to happen'

pip install events

python setup.py test
