Struct ForeignLspManager 

pub struct ForeignLspManager { /* private fields */ }

Manages child LSP server processes for foreign language blocks.

Each foreign language gets at most one child server. The manager handles lifecycle (start, shutdown), document synchronization, and request forwarding.

Implementations

impl ForeignLspManager

pub fn new(workspace_dir: PathBuf) -> Self

pub fn set_workspace_dir(&self, dir: PathBuf)

Update the workspace root directory.

Called from initialize() once the real workspace root is known from the client’s rootUri / workspaceFolders. This ensures child LSP servers receive the correct rootUri so they can discover project config files (e.g. pyrightconfig.json, virtualenvs).

pub async fn set_configured_extensions( &self, specs: Vec<ConfiguredExtensionSpec>, )

Set extension specs that should always be loaded for foreign-LSP discovery.

pub async fn start_server(&self, language: &str) -> Result<(), String>

Start a child language server for the given language, if not already running.

pub async fn update_documents( &self, source_uri: &str, source: &str, items: &[Item], current_file: Option<&Path>, workspace_root: Option<&Path>, ) -> Vec<Diagnostic>

Update virtual documents for all foreign function blocks in a parsed program.

Call this from analyze_document whenever the program is successfully parsed.

pub async fn handle_completion( &self, source_uri: &str, position: Position, items: &[Item], source: &str, ) -> Option<Vec<CompletionItem>>

Handle a completion request that falls inside a foreign function body.

Returns None if the position is not in a foreign block or delegation fails.

pub async fn handle_hover( &self, source_uri: &str, position: Position, items: &[Item], source: &str, ) -> Option<Hover>

Handle a hover request that falls inside a foreign function body.

pub async fn handle_signature_help( &self, source_uri: &str, position: Position, items: &[Item], source: &str, ) -> Option<SignatureHelp>

Handle a signature help request that falls inside a foreign function body.

pub async fn handle_definition( &self, source_uri: &str, position: Position, items: &[Item], source: &str, ) -> Option<GotoDefinitionResponse>

Handle go-to-definition for positions inside foreign function bodies.

pub async fn handle_references( &self, source_uri: &str, position: Position, items: &[Item], source: &str, ) -> Option<Vec<Location>>

Handle find-references for positions inside foreign function bodies.

pub async fn collect_semantic_tokens( &self, source_uri: &str, ) -> Vec<ForeignSemanticToken>

Collect semantic tokens for foreign blocks mapped into Shape coordinates.

pub async fn get_diagnostics(&self, source_uri: &str) -> Vec<Diagnostic>

Retrieve diagnostics from child language servers for foreign blocks in a source file.

Maps virtual document diagnostics back to Shape source positions.

pub fn map_diagnostic_to_shape( diagnostic: &Diagnostic, position_map: &PositionMap, ) -> Option<Diagnostic>

Map a diagnostic from a virtual document back to Shape source coordinates.

pub async fn shutdown(&self)

Shut down all child language servers gracefully.
