Check out the `official documentation <https://asyncio-dispatch.readthedocs.org/en/latest/>`_ Synopsis -------- Many callbacks can be connected to a Signal. When the Signal is triggered using its ``send()`` method, all connected callbacks will be scheduled for asynchronous execution. Connections can optionally be made with two types of filters, ``senders`` and ``keys``. If filters are used, the callback is only scheduled for execution if the Signal is sent with at least one matching ``sender`` or ``key``. A ``sender`` can be any object, while a ``key`` is more likely to be a ``string``. Under the hood, they use ``id()`` and ``hash()`` respectively. Callbacks are invoked with keyword arguments that allow the callback to determine which Signal is calling it and which ``senders`` and ``keys`` were specified. Additional keyword arguments can be added to the Signal when it is instantiated, and their default values can be replaced when the Signal is sent. Example ------- .. code:: python import asyncio from asyncio_dispatch import Signal @asyncio.coroutine def callback(**kwargs): print('callback was called!') loop = asyncio.get_event_loop() # create the signal signal = Signal(loop=loop) # connect the callback to the Signal - This is a coroutine! loop.run_until_complete(loop.create_task(signal.connect(callback))) # send the signal - This is also a coroutine! print('sending the signal.') loop.run_until_complete(loop.create_task(signal.send())) The above example will print the following: .. code:: bash sending the signal. callback was called! Features -------- * Supports the new async/await syntax found in python 3.5 and up * Callbacks can be a function, asyncio.coroutine, async def, class method, @staticmethod, or @classmethod * Multiple callbacks can be connected to the same signal * Callbacks can be called with additional keyword arguments containing references to arbitrary objects * Callbacks can be disconnected from a signal * Signals can hold weak or strong references to callbacks, allowing for automatic disconnection if a reference to a callback is not maintained, or conversely to persist one-off ``lambda`` expressions without needing to maintain a reference * Callbacks receive the ``Signal`` object that was used to schedule it, so multiple signals can be attached to the same callback and handled differently * Callbacks can be connected with ``senders`` or ``keys`` which cause the Signal to ignore the callback unless the signal is sent with a matching *Object* or *str* License ------- Released under the MIT license. Installation ------------ .. code:: bash pip install asyncio_dispatch
