merging import lines like isort

[nijel]

After some refactoring, several imports were removed and this was left:

from foo import (
    bar,
    baz,
)

bar()
baz()

With isort this is nicely formatted as:

from foo import bar, baz

bar()
baz()

But ruff does no formatting here and keeps the file as is.

Ruff 0.0.284 was executed as ruff check --fix --select I test.py with no config, isort as isort test.py with not config.

I think you’re looking for this setting: https://beta.ruff.rs/docs/settings/#isort-split-on-trailing-comma. Ruff defaults it to true while isort does not. (It’s a point of confusion as the isort docs state it defaults to true for their Black configuration, but doesn’t seem to do so in practice.)

Thanks, that's it. While reading through the doc, I didn't realize that something called split will actually toggle folding.

And isort documentation is indeed wrong on this, I've created PyCQA/isort#2163 for that.
