About the project

Ruff is very fast linter and formatter written in Rust. The maintainers own the project, choose releases, and publish their own documentation. This page records a few things worth knowing before you begin.

The project is run by its own contributors rather than by a company. Release cadence, supported platforms and documentation are all decided by the team behind it.

How releases reach a machine

Packaging differs from project to project. Some publish to system repositories, some to their own index, some only as source archives that a build tool expects.

What to confirm beforehand

Look at the supported versions before anything else. Projects narrow their platform range over time, and older systems can be dropped without much warning.

Once it is in place

A version query afterwards is usually enough to confirm the environment picked it up. If the result is unexpected, the usual causes are a stale path entry or a version manager resolving to a different release.
