Per-variable specification of boolean parameters in open_dataset #9218

Ostheer · 2024-07-08T13:42:17Z

Added feature to choose whether to apply mask_and_scale for each DataArray in a Dataset individually.

The mask_and_scale parameter can now not only be bool, but also a mapping from variable name (str) to bool.

- [?] User visible changes (including notable bug fixes) are documented in whats-new.rst

New functions/methods are listed in api.rst

I wasn't sure if I was supposed to edit whats-new.rst, so I didn't touch it.

for more information, see https://pre-commit.ci

Ostheer · 2024-07-12T12:25:39Z

Can someone tell me if and how I should edit the what's new file?

I could add something like

- Allow per-variable specification of `mask_and_scale` in `open_dataset`  (:pull:`9218`).
  By `Mathijs Verhaegh <https://github.com/Ostheer>`_.

But I'm not sure where, as I don't know into which upcoming release this commit would be included.

This looks good!

Great re whatsnew suggestion, within New Features works!

Could also easily extend to other arguments, like decode_times. What do you think?

Otherwise you lose all typing when you use that because it returns Any.

Added for 4 more params (46de50f)

Feature now affects:

mask_and_scale, decode_times, decode_timedelta, use_cftime, concat_characters

I resolved some minor Mypy issues stemming from the annotations on _item_or_default, but the Mypy and Mypy 3.9 tasks are still failing.

I can't find how the errors in the logs relate to any of the code changes. Any ideas?

These checks are failing on main as well. There are already some PRs open to fix these.

I would say this looks good.

I see. Can we then somehow merge this despite the failing checks? I don't think Github lets me.

headtr1ck · 2024-07-13T13:40:44Z

Yes, no worries.
Let's keep it a day or two for other people to check and then merge. Thanks!
