aioify

aioify (maintenance mode)

Authors of aioify and module-wrapper decided to discontinue support of these libraries since the idea: "let's convert sync libraries to async ones" works only for some cases. Existing releases of libraries won't be removed, but don't expect any changes since today. Feel free to fork these libraries, however, we don't recommend using the automatic sync-to-async library conversion approach, as unreliable. Instead, it's better to run synchronous functions asynchronously using https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.loop.run_in_executor or https://anyio.readthedocs.io/en/stable/api.html#running-code-in-worker-threads.

Old documentation

Make every function async and await-able.

Usage

pip install aioify

For example, make os, shutil and user defined function await-able.
