eventkit

\n

Release 1.0.1.

\n
\n
\n
\n

Event

\n
\n
\nclass eventkit.event.Event(name='', _with_error_done_events=True)[source]
\n

Enable event passing between loosely coupled components.\nThe event emits values to connected listeners and has\na selection of operators to create general data flow pipelines.

\n
\n
Parameters:
\n

name (str) – Name to use for this event.

\n
\n
\n
\n
\n__await__()[source]
\n

Asynchronously await the next emit of an event:

\n
async def coro():\n    args = await event\n    ...\n
\n
\n

If the event does an empty emit(), then the value\nof args is set to util.NO_VALUE.

\n

wait() and __await__() are each other’s inverse.

\n
\n\n
\n
\nasync __aiter__(skip_to_last=False, tuples=False)
\n

Synonym for aiter() with default arguments:

\n
async def coro():\n    async for args in event:\n        ...\n
\n
\n

aiterate() and __aiter__() are each other’s inverse.

\n
\n\n
\n
\nerror_event: Optional[Event]
\n

Sub event that emits errors from this event as\nemit(source, exception).

\n
\n\n
\n
\ndone_event: Optional[Event]
\n

Sub event that emits when this event is done as\nemit(source).

\n
\n\n
\n
\nname()[source]
\n

This event’s name.

\n
\n
Return type:
\n

str

\n
\n
\n
\n\n
\n
\ndone()[source]
\n

True if event has ended with no more emits coming,\nFalse otherwise.

\n
\n
Return type:
\n

bool

\n
\n
\n
\n\n
\n
\nset_done()[source]
\n

Set this event to be ended. The event should not emit anything\nafter that.

\n
\n\n
\n
\nvalue()[source]
\n

This event’s last emitted value.

\n
\n\n
\n
\nconnect(listener, error=None, done=None, keep_ref=False)[source]
\n

Connect a listener to this event. If the listener is added multiple\ntimes then it is invoked just as many times on emit.

\n

The += operator can be used as a synonym for this method:

\n
import eventkit as ev\n\ndef f(a, b):\n    print(a * b)\n\ndef g(a, b):\n    print(a / b)\n\nevent = ev.Event()\nevent += f\nevent += g\nevent.emit(10, 5)\n
\n
\n
\n
Parameters:
\n
    \n

  • listener – The callback to invoke on emit of this event.\nIt gets the *args from an emit as arguments.\nIf the listener is a coroutine function, or a function that\nreturns an awaitable, the awaitable is run in the\nasyncio event loop.

    • \n

  • error – The callback to invoke on error of this event.\nIt gets (this event, exception) as two arguments.

    • \n

  • done – The callback to invoke on ending of this event.\nIt gets this event as single argument.

    • \n

  • keep_ref (bool) –

      \n

    • True: A strong reference to the callable is kept

      • \n

    • False: If the callable allows weak refs and it is\ngarbage collected, then it is automatically disconnected\nfrom this event.

      • \n
    \n

    • \n
\n
\n
Return type:
\n

Event

\n
\n
\n
\n\n
\n
\ndisconnect(listener, error=None, done=None)[source]
\n

\n

The -= operator can be used as a synonym for this method.

\n
\n
Parameters:
\n
    \n

  • listener – The callback to disconnect. The callback is removed at\nmost once. It is valid if the callback is already\nnot connected.

    • \n

    • \n
\n
\n

\n
\n
\n
\n\n
\n

\n
\n
Parameters:
\n

args – Argument values to emit to listeners.

\n
\n
\n
\n\n
\n
\nemit_threadsafe(*args)[source]
\n

Threadsafe version of emit() that doesn’t invoke the\nlisteners directly but via the event loop of the main thread.

\n
\n\n
\n
\nclear()[source]
\n

Disconnect all listeners.

\n
\n\n
\n
\nrun()[source]
\n

Start the asyncio event loop, run this event to completion and\nreturn all values as a list:

\n
import eventkit as ev\n\nev.Timer(0.25, count=10).run()\n->\n[0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.25, 2.5]\n
\n
\n
\n

Note

\n

When running inside a Jupyter notebook this will give an error\nthat the asyncio event loop is already running. This can be\nremedied by applying\nnest_asyncio\nor by using the top-level await statement of Jupyter:

\n
await event.list()\n

Introduction

\n

The primary use cases of eventkit are

\n
    \n

  • to send events between loosely coupled components;

    • \n

  • to compose all kinds of event-driven data pipelines.

    • \n
\n

The interface is kept as Pythonic as possible,\nwith familiar names from Python and its libraries where possible.\nFor scheduling asyncio is used and there is seamless integration with it.

\n

See the examples and the\nintroduction notebook\nto get a true feel for the possibilities.

\n
\n
\n

Installation

\n
pip3 install eventkit\n
\n
\n

Python version 3.6 or higher is required.

\n
\n
\n

Examples

\n

Create an event and connect two listeners

\n
import eventkit as ev\n\ndef f(a, b):\n    print(a * b)\n\ndef g(a, b):\n    print(a / b)\n\nevent = ev.Event()\nevent += f\nevent += g\nevent.emit(10, 5)\n
\n
\n

Create a simple pipeline

\n
import eventkit as ev\n\nevent = (\n    ev.Sequence('abcde')\n    .map(str.upper)\n    .enumerate()\n)\n\nprint(event.run())  # in Jupyter: await event.list()\n
\n
\n

Output:

\n
[(0, 'A'), (1, 'B'), (2, 'C'), (3, 'D'), (4, 'E')]\n
\n
\n

Create a pipeline to get a running average and standard deviation

\n
import random\nimport eventkit as ev\n\nsource = ev.Range(1000).map(lambda i: random.gauss(0, 1))\n\nevent = source.array(500)[ev.ArrayMean, ev.ArrayStd].zip()\n\nprint(event.last().run())  # in Jupyter: await event.last()\n
\n
\n

Output:

\n
[(0.00790957852672618, 1.0345673260655333)]\n
\n
\n

Combine async iterators together

\n
import asyncio\nimport eventkit as ev\n\nasync def ait(r):\n    for i in r:\n        await asyncio.sleep(0.1)\n        yield i\n\nasync def main():\n    async for t in ev.Zip(ait('XYZ'), ait('123')):\n        print(t)\n\nasyncio.get_event_loop().run_until_complete(main())  # in Jupyter: await main()\n
\n
\n

Output:

\n
('X', '1')\n('Y', '2')\n('Z', '3')\n
\n
\n

Real-time video analysis pipeline

\n
self.video = VideoStream(conf.CAM_ID)\nscene = self.video | FaceTracker | SceneAnalyzer\nlastScene = scene.aiter(skip_to_last=True)\nasync for frame, persons in lastScene:\n    ...\n
\n
\n

Full source code

\n
\n
\n

Distributed computing

\n

The distex library provides a\npoolmap extension method to put multiple cores or machines to use:

\n
from distex import Pool\nimport eventkit as ev\nimport bz2\n\npool = Pool()\n# await pool  # un-comment in Jupyter\ndata = [b'A' * 1000000] * 1000\n\npipe = ev.Sequence(data).poolmap(pool, bz2.compress).map(len).mean().last()\n\nprint(pipe.run())  # in Jupyter: print(await pipe)\npool.shutdown()\n
\n
