Queue

Extension for asynckivy programs.

from kivy.app import App
import asynckivy as ak
from asynckivy_ext.queue import Queue


async def producer(q):
    for c in "ABC":
        await q.put(c)
        print('produced', c)
    q.half_close()


async def consumer(q):
    async for c in q:
        print('consumed', c)


q = Queue(capacity=1)
ak.start(producer(q))
ak.start(consumer(q))
App().run()

produced A
consumed A
produced B
consumed B
produced C
consumed C

The consumer() above can be written in more primitive way:

from asynckivy_ext.queue import Closed


async def consumer(q):
    try:
        while True:
            c = await q.get()
            print('consumed', c)
    except Closed:
        pass

Installation

It's recommended to pin the minor version, because if it changed, it means some important breaking changes occurred.
