##### Ruff's language server is now in Beta
`v0.4.5` marks the official Beta release of `ruff server`, an integrated language server built into Ruff.
`ruff server` supports the same feature set as `ruff-lsp`, powering linting, formatting, and
code fixes in Ruff's editor integrations -- but with superior performance and
no installation required. We'd love your feedback!
You can enable `ruff server` in the [VS Code extension](https://togithub.com/astral-sh/ruff-vscode?tab=readme-ov-file#enabling-the-rust-based-language-server) today.

[Compare Source](https://togithub.com/astral-sh/ruff/compare/v0.3.7...v0.4.0)
##### A new, hand-written parser
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](https://astral.sh/blog/ruff-v0.4.0) for more details!
See [#10036](https://togithub.com/astral-sh/ruff/pull/10036) for implementation details.
##### A new language server in Rust
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](https://microsoft.github.io/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. Itβs also faster than our previous [Python-based language server](https://togithub.com/astral-sh/ruff-lsp)
\-- 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](https://togithub.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md).

There's a lot to say about this exciting change, so check out the [blog post](https://astral.sh/blog/ruff-v0.4.0) for more details! See [#10036](https://togithub.com/astral-sh/ruff/pull/10036) for implementation details. ##### A new language server in Rust 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](https://microsoft.github.io/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. Itβs also faster than our previous [Python-based language server](https://togithub.com/astral-sh/ruff-lsp) \-- 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](https://togithub.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md). ##### Preview features - \[`pycodestyle`] Do not trigger `E3` rules on `def`s following a function/method with a dummy body ([#10704](https://togithub.com/astral-sh/ruff/pull/10704)) - \[`pylint`] Implement `invalid-bytes-returned` (`E0308`) ([#10959](https://togithub.com/astral-sh/ruff/pull/10959)) - \[`pylint`] Implement `invalid-length-returned` (`E0303`) ([#10963](https://togithub.com/astral-sh/ruff/pull/10963)) - \[`pylint`] Implement `self-cls-assignment` (`W0642`) ([#9267](https://togithub.com/astral-sh/ruff/pull/9267)) - \[`pylint`] Omit stubs from `invalid-bool` and `invalid-str-return-type` ([#11008](https://togithub.com/astral-sh/ruff/pull/11008)) - \[`ruff`] New rule `unused-async` (`RUF029`) to detect unneeded `async` keywords on functions ([#9966](https://togithub.com/astral-sh/ruff/pull/9966)) ##### Rule changes - \[`flake8-bandit`] Allow `urllib.request.urlopen` calls with static `Request` argument (`S310`) ([#10964](https://togithub.com/astral-sh/ruff/pull/10964)) - \[`flake8-bugbear`] Treat `raise NotImplemented`-only bodies as stub functions (`B006`) ([#10990](https://togithub.com/astral-sh/ruff/pull/10990)) - \[`flake8-slots`] Respect same-file `Enum` subclasses (`SLOT000`) ([#11006](https://togithub.com/astral-sh/ruff/pull/11006)) - \[`pylint`] Support inverted comparisons (`PLR1730`) ([#10920](https://togithub.com/astral-sh/ruff/pull/10920)) ##### Linter - Improve handling of builtin symbols in linter rules ([#10919](https://togithub.com/astral-sh/ruff/pull/10919)) - Improve display of rules in `--show-settings` ([#11003](https://togithub.com/astral-sh/ruff/pull/11003)) - Improve inference capabilities of the `BuiltinTypeChecker` ([#10976](https://togithub.com/astral-sh/ruff/pull/10976)) - Resolve classes and functions relative to script name ([#10965](https://togithub.com/astral-sh/ruff/pull/10965)) - Improve performance of `RuleTable::any_enabled` ([#10971](https://togithub.com/astral-sh/ruff/pull/10971)) ##### Server *This section is devoted to updates for our new language server, written in Rust.* - Enable ruff-specific source actions ([#10916](https://togithub.com/astral-sh/ruff/pull/10916)) - Refreshes diagnostics for open files when file configuration is changed ([#10988](https://togithub.com/astral-sh/ruff/pull/10988)) - Important errors are now shown as popups ([#10951](https://togithub.com/astral-sh/ruff/pull/10951)) - Introduce settings for directly configuring the linter and formatter ([#10984](https://togithub.com/astral-sh/ruff/pull/10984)) - Resolve configuration for each document individually ([#10950](https://togithub.com/astral-sh/ruff/pull/10950)) - Write a setup guide for Neovim ([#10987](https://togithub.com/astral-sh/ruff/pull/10987)) ##### Configuration - Add `RUFF_OUTPUT_FILE` environment variable support ([#10992](https://togithub.com/astral-sh/ruff/pull/10992)) ##### Bug fixes - Avoid `non-augmented-assignment` for reversed, non-commutative operators (`PLR6104`) ([#10909](https://togithub.com/astral-sh/ruff/pull/10909)) - Limit commutative non-augmented-assignments to primitive data types (`PLR6104`) ([#10912](https://togithub.com/astral-sh/ruff/pull/10912)) - Respect `per-file-ignores` for `RUF100` on blanket `# noqa` ([#10908](https://togithub.com/astral-sh/ruff/pull/10908)) - Consider `if` expression for parenthesized with items parsing ([#11010](https://togithub.com/astral-sh/ruff/pull/11010)) - Consider binary expr for parenthesized with items parsing ([#11012](https://togithub.com/astral-sh/ruff/pull/11012)) - Reset `FOR_TARGET` context for all kinds of parentheses ([#11009](https://togithub.com/astral-sh/ruff/pull/11009))Configuration
