asynctor

Some async functions that using anyio, and toolkit for excel read.

Or install by ssh

uv pip install "asynctor[redis] @git+ssh://[e-mail]/waketzheng/asynctor.git"

Usage

• Async function that compare asyncio but use anyio: bulk_gather/gather/run

>>> import asynctor
>>> async def foo():
...     return 1
...
>>> await asynctor.bulk_gather([foo(), foo()], limit=200)
(1, 1)
>>> await asynctor.gather(foo(), foo())
(1, 1)
>>> asynctor.run(gather(foo(), foo()))
(1, 1)

• run_async: start a new thread to run async function and get result of it

>>> from asynctor import run_async
>>> async def foo(a=1):
...     return a
...
>>> run_async(foo) == run_async(foo()) == run_async(foo, 1) == 1
True

• timeit

>>> import time
>>> import anyio
>>> from asynctor import timeit
>>> @timeit
... async def sleep_test():
...     await anyio.sleep(3)
...
>>> await sleep()
sleep_test Cost: 3.0 seconds

>>> @timeit
... def sleep_test2():
...     time.sleep(3.1)
...
>>> sleep_test2()
sleep_test2 Cost: 3.1 seconds
>>> with timeit('Sleeping'):
...     sleep()
...
Sleeping Cost: 3.0 seconds

• AioRedis

pip install "asynctor[redis]"

from asynctor.contrib.fastapi import AioRedisDep, register_aioredis
from fastapi import FastAPI

app = FastAPI()
register_aioredis(app)

@app.get('/')
async def root(redis: AioRedisDep) -> list[str]:
    return await redis.keys()

@app.get('/redis')
async def get_value_from_redis_by_key(redis: AioRedisDep, key: str) -> str:
    value = await redis.get(key)
    if not value:
        return ''
    return value.decode()

• Async Test Fixtures

pip install "asynctor[testing]"

import pytest
from asynctor.testing import anyio_backend_fixture, async_client_fixture
from httpx import AsyncClient

from main import app

anyio_backend = anyio_backend_fixture()
client = async_client_fixture(app)

@pytest.mark.anyio
async def test_api(client: AsyncClient):
    response = await client.get("/")
    assert response.status_code == 200

• runserver for fastapi projects

pip install asynctor fastapi uvicorn

from fastapi import FastAPI

app = FastAPI()


def main() -> None:
    from asynctor.contrib.fastapi import runserver

    runserver(app)


if __name__ == '__main__':
    main()

• Read Excel File

pandas/openpyxl is required, can be installed with xlsx extra: pip install "asynctor[xlsx]"

>>> from asynctor.xlsx import load_xlsx
>>> await load_xlsx('tests/demo.xlsx')
[{'Column1': 'row1-\\t%c', 'Column2\nMultiLines': 0, 'Column 3': 1, 4: ''}, {'Column1': 'r2c1\n00', 'Column2\nMultiLines': 'r2 c2', 'Column 3': 2, 4: ''}]
