Mypy support
Hey,
Great job there, i’m wondering if you plan to support proper python typing ? I’m happy to provide very easily a sync interface to my library unfortunately, everything mypy related is broken in sync context.
If not, do you have any tips to override the typing ?
As i’m tampering with the library i managed to create my own typed wrapper above async_to_sync_wraps.
It’s rudimentary but it could help a lot of people. :)
from typing import (
Any,
AsyncGenerator,
Callable,
Coroutine,
Generator,
TypeVar,
overload,
Union,
)
import universalasync
T = TypeVar("T")
@overload
def synchronize(
function: Callable[..., Coroutine[Any, Any, T]]
) -> Callable[..., Union[Coroutine[Any, Any, T], T]]: ...
@overload
def synchronize(
function: Callable[..., AsyncGenerator[T, None]]
) -> Callable[..., Union[AsyncGenerator[T, None], Generator[T, None, None]]]: ...
def synchronize(
f: Callable[..., Coroutine[Any, Any, T]],
) -> Callable[..., T]:
return universalasync.async_to_sync_wraps(f)
The problem is that later, mypy does not manage to infer the async or sync value from the call context.
There was a closed request for a way to handle the request context of the call (async or sync) in mypy but it was rejected: https://github.com/python/mypy/issues/9837
I’d like to request a review of my matter, pretty please. Don’t give up on me. :)
Hi! Really sorry for the delay I would really like to add some proper typing, but my knowledge of python typing is limited Do you have any kind of example code I can try to run mypy on?
