Documentation site and generated agent skills for rune-langium APIs

Use createRuneLspServer() when you need diagnostics, hover, completion, and go-to-definition for .rosetta files in an editor or web app. Reach for createConnectionAdapter() when tests or nonstandard transports need to plug into the same server lifecycle.

When to Use

Use this skill when:

• Embedding a Rune DSL language server in a web application via WebSocket → use createRuneLspServer
• Running a standalone LSP server process bridging to a VS Code / Theia client → use createRuneLspServer
• Integration-testing LSP features (hover, completion, diagnostics) → use createRuneLspServer
• Wiring a custom @lspeasy/server instance into Langium in tests or advanced embedding scenarios where createRuneLspServer() does not fit. → use createConnectionAdapter

Do NOT use when:

• Parsing .rosetta files in a script — use createRuneDslServices() and parse() / parseWorkspace() instead (no LSP overhead). (createRuneLspServer)
• Creating multiple servers in the same process — each server maintains its own Langium workspace index; sharing a workspace across servers requires custom ServiceRegistry wiring. (createRuneLspServer)
• Normal usage — prefer createRuneLspServer() which calls this internally. (createConnectionAdapter)

Quick Reference

LSP Server: createRuneLspServer (Create a fully-wired Rune DSL LSP server backed by @lspeasy/server), createConnectionAdapter (Create a vscode-languageserver-compatible Connection backed by an @lspeasy/server LSPServer), RuneLspServer (A fully-wired Rune DSL LSP server instance) cf-durable-object-transport: DurableObjectWebSocketTransport

References

Load these on demand — do NOT read all at once:

• When calling any function → read references/functions.md for full signatures, parameters, and return types
• When using a class → read references/classes.md for properties, methods, and inheritance
• When defining typed variables or function parameters → read references/types.md
