## Summary This PR unifies the ruff `Message` enum variants for syntax errors and rule violations into a single `Message` struct consisting of a shared `db::Diagnostic` and some additional, optional fields used for some rule violations. This version of `Message` is nearly a drop-in replacement for `ruff_diagnostics::Diagnostic`, which is the next step I have in mind for the refactor. I think this is also a useful checkpoint because we could possibly add some of these optional fields to the new `Diagnostic` type. I think we've previously discussed wanting support for `Fix`es, but the other fields seem less relevant, so we may just need to preserve the `Message` wrapper for a bit longer. ## Test plan Existing tests --------- Co-authored-by: Micha Reiser <micha@reiser.io>
The Ruff Language Server
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.
Refer to the documentation for more information on how to set up the language server with your editor and configure it to your liking.
