How to install ruff

Ruff is a very fast linter and formatter written in Rust. What follows is background, not a walkthrough. The authoritative version always lives with the project's own team.

Paths onto a machine

Expect differences between platforms. The same project may reach one system through a package index and another through a source build.

Who is behind it

Direction comes from the people who write the code. Their decisions on releases and support are the ones that matter.

Worth confirming early

Check platform support first. Recent work in this space generally assumes a current runtime and a reasonably modern system.

Interpreting what you see

Surprises here are rarely the project's fault. Ordering inside the environment decides which copy wins, and that ordering is easy to get wrong.

What this domain is

These pages exist as notes. No files are hosted, and no project material is reproduced on this domain.

Keeping environments clean

Isolating environments, whether with a version manager or per-project directories, removes a whole category of confusing behaviour later on.
