## Summary
Fixes #11534.
`DocumentQuery::source_type` now returns `PySourceType::Stub` when the
document is a `.pyi` file.
## Test Plan
I confirmed that stub-specific rule violations appeared with a build
from this PR (they were not visible from a `main` build).

The Ruff Language Server
Welcome!
ruff server is a language server that powers Ruff's editor integrations.
The job of the language server is to listen for requests from the client (in this case, the code editor of your choice) and call into Ruff's linter and formatter crates to construct real-time diagnostics or formatted code, which is then sent back to the client. It also tracks configuration files in your editor's workspace, and will refresh its in-memory configuration whenever those files are modified.
Setup
We have specific setup instructions depending on your editor. If you don't see your editor on this list and would like a setup guide, please open an issue.
If you're transferring your configuration from ruff-lsp, regardless of
editor, there are several settings which have changed or are no longer available. See the migration guide for
more.
VS Code
Install the Ruff extension from the VS Code Marketplace.
As this server is still in Beta, you will need to enable the "Native Server" extension setting, either in the settings UI:
Or in your settings.json:
{
"ruff.nativeServer": true
}
From there, you can configure Ruff to format Python code on-save with:
{
"[python]": {
"editor.formatOnSave": true,
"editor.defaultFormatter": "charliermarsh.ruff"
}
}
For more, see Configuring VS Code in the Ruff extension documentation.
By default, the extension will run against the ruff binary that it discovers in your environment. If you don't have
ruff installed, the extension will fall back to a bundled version of the binary.
Neovim
See the Neovim setup guide.
