Thanks a lot for your comments. I'm reworking it so that the tox tests run your pytest-based testing facility (which I had somehow overlooked when I prepared this PR.)

By the way, the ruff linter fails also in the master branch - see https://github.com/abelfunctions/abelfunctions/actions/runs/12719866991/job/35460723682

Yeah ruff updated, I'll address that

The latest version of ruff is now supported in master

On this branch, ruff on github actions complains

Run ruff check --output-format=github
Would reformat: setup.py
1 file would be reformatted, 41 files already formatted

Can't reproduce locally (with same version of ruff, 0.9.2). Any ideas?

Not sure what the issue was but running locally in the repository root I get

>>> ruff format
1 file reformatted, 41 files left unchanged
>>> ruff -V
ruff 0.9.2

so I've committed that result. Hopefully passes now

Rebased on top of the current master, ready for review/merging.

The package works as well with passagemath as it does with recent versions of Sage: Errors with Singular remain, as discussed in #270.

Thanks @mkoeppe, I don't want to merge this in with the tests failing but looking at PyPi it seems like passagemath versions only go back as far as sage 10.4? The last version of sage that the tests worked on was 10.1 so I'd ideally like to require passagemath <= 10.1 for now until #270 is fixed but doesn't look possible.

The oldest passsagemath is version 10.4; I started this fork only in October 2024, in response to the collapse of governance in the Sage project.

Wonderful!
