Type hints for xr.open_dataset

[adamjstewart]

I've noticed that xarray has partial type hinting support. What's the timeline for full type hinting support? In particular, I'm seeing:

error: Call to untyped function "open_dataset" in typed context

because xr.open_dataset does not yet have type hints.

There's no timeline for complete type hinting -- or most other features in xarray, for that matter. Xarray is mostly a volunteer run project that depends on user contributions.

We would certainly welcome the addition of type hints for open_dataset(). At the very least, we could clarify that open_dataset() return an xarray.Dataset object.

Good to know, I'll try to add type hints and submit a PR if I get the chance.
