pint-cf: A Lark-based parser and units registry for CF-compliance with pint

[pgamez]

Hi all,

I’ve recently published pint-cf, a lightweight package designed to bring CF-compliant unit support to pint. While excellent tools like yours and cf-xarray already handle many use cases, they often rely on regex-based preprocessors or partial custom definitions to bridge the gap between UDUNITS-2 and Pint.

This package tries to provide a more formal approach:

• A specific CF unit parser, a Lark-based processor that translates CF units string into pint-compatible expressions.
• A preconfigured pint.UnitRegistry that loads UDUNITS2 definitions and handles pluralization by disabling pint's standard suffixes
• A dedicated CF formatter, supporting both long and short forms.

Code is available at https://github.com/pgamez/pint-cf

I would be very grateful if you could take a look and share any feedback.

I hope you find it interesting!

Thanks,

Pedro
