Struct LspManager 

pub struct LspManager { /* private fields */ }

Manages lifecycle of multiple language server clients.

Lazily starts LSP servers on-demand based on file extension. Each extension maps to at most one running server instance. Servers are started when first needed and remain running until explicitly shut down or the manager is dropped.

Implementations

impl LspManager

pub fn new( project_root: PathBuf, registry: LspServerRegistry, enabled: bool, diagnostics_settle_delay_ms: u64, ) -> Self

Create a new LSP manager without an event channel. Status changes are silently dropped — appropriate for tests and headless mode where no UI consumes them.

pub fn with_event_channel( project_root: PathBuf, registry: LspServerRegistry, enabled: bool, diagnostics_settle_delay_ms: u64, ) -> (Self, UnboundedReceiver<LspConnectEvent>)

Create a new LSP manager paired with a receiver for connection status events. The TUI event loop consumes the receiver and renders Started / Failed events as scrollback lines next to the existing MCP rendering.

pub fn diagnostics_settle_delay_ms(&self) -> u64

Get the configured diagnostics settle delay in milliseconds.

pub async fn ensure_server(&self, file_path: &Path) -> Result<bool>

Ensure a language server is running for the given file’s extension. Returns Ok(true) if a server is (now) running, Ok(false) if no server is configured or the command is not installed.

pub async fn diagnostics(&self, path: &Path) -> Vec<Diagnostic>

Get diagnostics for a specific file. Returns an empty vector if no server is running for that file type.

pub async fn all_diagnostics(&self) -> Vec<Diagnostic>

Get all diagnostics from all running servers. Aggregates diagnostics across all file types with active servers.

pub async fn notify_file_changed( &self, path: &Path, content: &str, ) -> Result<bool>

Ensure the appropriate server is running, then notify it that a file changed. This triggers the server to re-analyze the file and publish updated diagnostics. Returns Ok(true) if a server received the notification, Ok(false) otherwise.

pub async fn active_servers(&self) -> Vec<String>

List the file extensions that have active servers. Useful for debugging and status display.

pub async fn shutdown(&self)

Shutdown all running language servers gracefully. Sends shutdown request, exit notification, then kills the process. Errors are logged but not propagated.
