  I updated a ~3k line Python project with this the other day. I was using v0.15.x beforehand. It didn't take too long and the new rules do improve code quality. It caught quite a few things previous versions didn't.Here's a few commits of changes:(A whole bunch of manual changes based on its suggestions) https://github.com/nickjj/plutus/commit/9af66d31f98bef841588...(Re-enable line length) https://github.com/nickjj/plutus/commit/21789f89bbcee37913c1...(Force _ prefix for unused variables) https://github.com/nickjj/plutus/commit/a272c77b932e1c78558a...(Auto-corrected by Ruff) https://github.com/nickjj/plutus/commit/6fe69cf88385ebdf9b8c...

  The amount of fascination that people have with these "grammar nazi" bots -- some of them implementing completely arbitrary "rules" and some of them disagreeing with others on what "good" Python code should look like -- doesn't stop to amaze me.Here's "bad" code: important_numbers = { 'x': 3, 'y': 42, # Answer to the Ultimate Question! 'z': 2 } Here's what "good" code should look like: important_numbers = {"x": 3, "y": 42, "z": 2} # Answer to the Ultimate Question! Which completely misses the writer's intent. But did you notice that there are two spaces before the pound now? Also, the quotes are now double because apparently it's somehow more kosher! So much improvement!The actual problems in the code I work with are not the spaces at the end of line or imports in non-alphabetic order, it's the 10-line list comprehensions that are so long that they're impossible for me to parse. None of these tools catch that. My place used pylint, flake8, black, ruff -- with hundreds of commits on every change. All that energy could be better spent elsewhere.

  Great to see ruff, ty and uv being actively developed, even after Astral was acquired by OpenAI.

  I really wish Ruff would introduce something similar to Nix’s stateVersion, which is used to determine the set of defaults that will be applied. Updating Ruff at a scale beyond a single repo is a bit of a crapshoot currently, with every version introducing a bunch of new default rules which you then have to deal with immediately (either by turning them off or fixing them).I’m aware we could have an allowlist in place which specifies all rules that are turned on but I’d much rather have a simpler config file, and be able to bump the state version at a good time for everyone to spend a few hours fixing new violations.

  I wish Go had something like Ruff! A lot of languages are getting amazing tool but Go has a very fragmented ecosystem with a lot of tools but none of them feel as high quality has the likes of Ruff, Oxc, Biome or even PHP's Mago

  This is great news! With the advent of agentic coding, strong linting is more important than ever. What I'd really like to see is forbidigo for more languages.

  Good news. enabling 413 rules by default means most projects get useful linting without touching the config at all!
• luciana1u
  413 rules and somehow every codebase I join still has the same three arguments about import sorting

  Looks like it's recommended to use zero-config now, which is great! My new .ruff.toml is just: line-length = 300

  If you listen closely you can hear the thousands of CI jobs that just pull latest UV failing all at once.

  this is writing 3000 lines in this era you must be a normal human being

  Default on lint is good for agent fleets. fwiw, I watched one agent "fix" an unfamiliar rule by deleting the test; perfect compliance, tiny misunderstanding.

  ran 0.16 on a file with no config, it flags unsorted imports and `except Exception` by default now

  I find it somehow interesting that a tool for Python is written in Rust.

  Ruff v0.16 has a small number of breaking changes Why. Why must my poor semver be hurt so!I sorta kinda get why `ty` is pre v1.0.0 -- it's a typechecker that doesn't check a huge number of types. But what are we waiting for with `ruff`? Surely it's eaten whatever the old options were (black? maybe a few takes on py+lint?) by now many times over, and is even more dominant than `uv`.I run this program hundreds of times a day so I'm generally excited for new features, but I guess the OAI acquisition has made me ornery when it comes to these folks. Apologies to kindly nerds who made this release happen, and congrats <3

  Every new single piece of software calls itself “extremely fast”, “blazingly fast”, it gets tiring.
