micropython-stdlib-stubs

A limited size copy of typesheds stdlib directory. https://github.com/python/typeshed/tree/main/stdlib

This is used as a dependency in the micropython-*-stub packages to allow overriding of some of the stdlib modules with MicroPython specific implementations.

MicroPython specific updates to:

collections

If you have suggestions or find any issues with the stubs, please report them in the MicroPython-stubs Discussions

Building

This is a short description of the steps taken to create or update the stubs for the micropython-stdlib-stubs distribution. this package is built using uv build and published using uv publish.

There are two possible reasons to rebuild

Rebuild in order to update from the reference-stubs or ducument-stubs. This will use the same typeshed stubs, and infuse or enrich them with new information from MicroPython.
Rebuild in order to update to a newer version of theof the typeshedrepo.for this you will need to manually advance the typeset repo to a newer version. Perhaps the newest versionand then rerun the update script it might be that due to the changes in the base 5 stubs that you'll need to make updates to the updatescript in order to accommodate for that.

Steps

clone the typeshed repository

cd repos
git clone https://github.com/python/typeshed.git
cd typeshed
git checkout <commit-hash>

update the version in pyproject toml to the new version ( .postnn)
from the publish/micropython-stdlib-stubs directory
- run python build.py
update and publish the micropython-stdlib-stubs package
```
uv publish
```
commit the changes to the micropython-stdlib-stubs repository

asyncio notes

asyncio

no _asyncio.pyi stubs to avoid conflict with stdlib re-use
Generators are not values - but are always callables, or coroutines so rewrite open_connection: Generator ## = <generator> to async def open_connection () -> Callable[..., Awaitable[Tuple[StreamReader, StreamWriter]]] or similar

Publish to PyPi

Publish using uv publish.
