module-wrapper

module-wrapper - module wrapper Python library (maintenance mode)

Warning

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

module-wrapper contains wrap function, which is used to wrap module, class, function or another variable recursively.

Installation

To install from PyPI run:

$ pip install module-wrapper

Usage

Example from aioify:

from functools import wraps, partial
import asyncio

import module_wrapper


__all__ = ['aioify']


def wrap(func):
    @wraps(func)
    async def run(*args, loop=None, executor=None, **kwargs):
        if loop is None:
            loop = asyncio.get_event_loop()
        pfunc = partial(func, *args, **kwargs)
        return await loop.run_in_executor(executor, pfunc)
    return run


def aioify(obj, name=None):
    def create(cls):
        return 'create', wrap(cls)

    return module_wrapper.wrap(obj=obj, wrapper=wrap, methods_to_add={create}, name=name)
