Ruff's new parser is >2x faster, which translates to a 20-40% speedup for all linting and formatting invocations. There's a lot to say about this exciting change, so check out the blog post for more details!
With this release, we also want to highlight our new language server. ruff server is a Rust-powered language server that comes built-in with Ruff. It can be used with any editor that supports the Language Server Protocol (LSP). It uses a multi-threaded, lock-free architecture inspired by rust-analyzer and it will open the door for a lot of exciting features. It’s also faster than our previous Python-based language server -- but you probably guessed that already.
ruff server is only in alpha, but it has a lot of features that you can try out today:
Lints Python files automatically and shows quick-fixes when available
Formats Python files, with support for range formatting
Comes with commands for quickly performing actions: ruff.applyAutofix, ruff.applyFormat, and ruff.applyOrganizeImports
Supports source.fixAll and source.organizeImports source actions
Automatically reloads your project configuration when you change it
To setup ruff server with your editor, refer to the README.md.
