rune-langium / lsp-server/src / RuneLspServer

Interface: RuneLspServer

Defined in: packages/lsp-server/src/rune-dsl-server.ts:66

A fully-wired Rune DSL LSP server instance.

Remarks

Returned by createRuneLspServer. Exposes the underlying @lspeasy/server instance and Langium services for advanced use cases (testing, custom middleware, capability introspection).

Pitfalls

• Do NOT call listen() before the server is fully initialized — all Langium providers are registered during createRuneLspServer() synchronously via startLanguageServer(shared). The server is ready to accept connections as soon as this factory function returns.
• Diagnostics are sent as textDocument/publishDiagnostics notifications (not responses). Clients must register a notification handler; they will not appear as request responses.
• Do NOT access shared or services from a concurrent request handler without understanding Langium's document locking model — document builds and index updates are not thread-safe.
