Ruff check path/to/code/ -select F401 -select F403 -quiet Rule enablement and disablement, file discovery, logging level, and more: Some configuration options can be provided via the command-line, such as those related to # Unlike Flake8, default to a complexity level of 10. line-length = 88 # Allow unused variables when underscore-prefixed. # Exclude a variety of commonly ignored directories. # Allow autofix for all enabled rules (when `-fix`) is provided. # Enable pycodestyle (`E`) and Pyflakes (`F`) codes by default. Table of Contentsįor more, see the documentation. It was working till I intentionally introduced some errors. Only one downside so far: it's so fast I couldn't believe It as an actual commit hook, which is terrific. This is an enormous quality of life improvement for local dev. Ruff is ~150-200x faster than flake8 on my machine, scanning the whole repo takes ~0.2s instead of Running ruff against our entire codebase takes. Our largest module (dagster itself, 250k LOC) pylint takes about 2.5 minutes, parallelized across 4Ĭores on my M1. Why is Ruff a gamechanger? Primarily because it is nearly 1000x faster. Ruff is so fast that sometimes I add an intentional bug in the code just to confirm it's actually Ruff is extremely actively developed and used in major open-source projects like:
Ruff can be used to replace Flake8 (plus dozens of plugins),Īll while executing tens or hundreds of times faster than any individual tool. Ruff aims to be orders of magnitude faster than alternative tools while integrating moreįunctionality behind a single, common interface. 🌎 Monorepo-friendly, with hierarchical and cascading configuration.⌨️ First-party editor integrations for VS Code and more.
