that's ruffly-all.

Answering what's necessary to migrate to ruff right now.

Motivation

Starting with ruff is simple. But enabling "ALL" rules in an existing application? That’s a challenge.

This project helps identify the minimal set of rules to disable temporarily, ensuring the CI remains green while allowing maintainers to iteratively fix their codebase at their own pace.

Installation

pip install ruffly-all

or

cargo install ruffly-all

Usage

Find a project you'd like to use ruff in, we'll be using pylint as an example[^1].

cd pylint/
ruffly-all

[tool.ruff]
lint.select = [ "ALL" ]
