Introducing ruff as a linter to replace pylint, flake8 and isort #2634

NOTE: Kedro datasets are moving from kedro.extras.datasets to a separate kedro-datasets package in
kedro-plugins repository. Any changes to the dataset implementations
should be done by opening a pull request in that repository.

Description

The goal for this is to use ruff to replace pylint, we should aim at compatible (99.9%) for this scope. We can decide later rather we should enable extra rule set.

ruff is much fast than pylint, which kills dev productivity for trivial changes. black will be kept because ruff is not a formatter although it can flag issues with formatting.

Development notes

Update linting.md
Remove isort,flake8,pylint from our CI (noted the dependencies are still here because we only deprecate kedro lint in 0.19.0`

Playing around with it, it's amazingly fast. I get confused a little bit with max-length. It seems that it can only warn the line is too long but couldn't fix it.

So I configure it to ignore E501(line-length), and just run black over it instead. There are subtle difference so they are not 1:1 mapping, but I guess black is doing a good job there and I am not worry about it.

To test this you can still uncomment the existing setup. They are mostly identical but with some slight difference as ruff is not a 100% replacement to the existing tools.

This still calls pylint right? Maybe we can remove it from CI to see the difference in execution times

There are many linting error, many of them are not difference between ruff and pylint but rather we are using old pylint version.

For the changes that are obvious and meaningful, I have applied the changes and suppressed the rest.

For example, this is a good fix hinted by ruff e0275f0.

Ruff allows you to have different sets of rules for these cases. Run the linter once, and select/ignore rules for testing.

For an example, check GitHub.com/ing-bank/popmon

@sbrugman Could you share a link? Not sure if I missed anything, I checked their config but it does not use any arguments.

Great work @noklam ⭐ I went through most of the changed files and can see that the changes minimal and mostly just changing # pylint: disable to # noqa.

I don't want this PR stuck forever, since this is already very useful to speed up dev.

astrojuanlu · 2023-07-20T16:46:12Z

I agree it would be super cool to get this in ASAP. Plugins can follow suit.

Just to clarify, is that something you want to do in this PR for the CI to pass?

noklam · 2023-07-20T17:11:49Z

No, I will save this for future PRs.

The lining is still failing for weird reason, I cannot reproduce it anywhere so I may have to ssh into it.

Other than that it's block by the E2e test.

noklam · 2023-07-20T22:17:52Z

The unsort import error is mysteriou, I cannot reproduce it anywhere. It's not important at all so I silent this error for the micropkg.py.
