Integrated Language Server (#10723)
# Description This commit integrates a language server into nushell so that IDEs don't have to convert CLI option back and forth. - fixes https://github.com/nushell/vscode-nushell-lang/issues/117 - fixes https://github.com/jokeyrhyme/nuls/issues/8 Tracking tasks - [x] [textDocument/hover](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_hover) -> `nu --ide-hover` - [x] [textDocument/completion](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_completion) -> `nu --ide-complete` - [x] [textDocument/definition](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_definition) -> `nu --ide-goto-def` - ~~[ ] [textDocument/didChange](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_didChange), [textDocument/didClose](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_didClose), and [textDocument/didOpen](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_didOpen)~~ (will be done in a follow-up PR) - ~~[ ] [textDocument/inlayHint](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_inlayHint) -> `nu --ide-check`~~ (will be done in a follow-up PR) - ~~[ ] [textDocument/publishDiagnostics](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_publishDiagnostics) -> `nu --ide-check`~~ (will be done in a follow-up PR) - ~~[ ] [workspace/configuration](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#workspace_configuration)~~ (will be done in a follow-up PR) - ~~[ ] [workspace/didChangeConfiguration](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#workspace_didChangeConfiguration)~~ (will be done in a follow-up PR) # User-Facing Changes The command line options `--lsp` will start a LSP server. # Tests + Formatting <!-- Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass (on Windows make sure to [enable developer mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging)) - `cargo run -- -c "use std testing; testing run-tests --path crates/nu-std"` to run the tests for the standard library > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` --> # After Submitting <!-- If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. -->
