asy 0.0.2

No project description provided

asy

asy is easy and powerful for asyncio.

Motivation for development

• Simple cancellation
• Improve the coordination of async functions between libraries
• No more programs for execution management
• Develop specifications like ASGI

Installation

pip install asy

Getting started

Create deamons, in example.py:

import asyncio

# cancelable limited loop
async def func1(token):
    for i in range(10):
        if token.is_cancelled:
            break
        print("waiting")
        await asyncio.sleep(1)
    print("complete func2.")

# cancelable infinity loop
async def func2():
    while True:
        print("waiting")
        await asyncio.sleep(1)

# uncancelable limited loop
def func3():
    for i in range(1000):
        print(i)

# from callable
class YourDeamon:
    async def __call__(self, token):
        while not token.is_cancelled:
            await asyncio.sleep(1)
        print("complete.")

func4 = YourDeamon()


# Do not run
# infinity loop
# async def func5()):
#     while True:
#         print("waiting")

Run in shell.

python3 -m asy example:func1 example:func2 example:func3 example:func4

Run in Python script.

import asy
from example import func1, func2, func3, func4

supervisor = asy.supervise(func1, func2, func3, func4)
supervisor.run()

# or
asy.run(func1, func2, func3, func4)

Let's end the daemon with Ctrl-C and enjoy asy!

Caution

asy is a beta version. Please do not use it in production.
