System Documentation

What problem does it solve?

Langium-based projects can be difficult to navigate because behavior is spread across grammar syntax, generated artifacts, a dependency-injection runtime, document state processing, linking, validation, and LSP wiring.

Core Features & Use Cases

  • End-to-end project comprehension: Covers the full lifecycle from .langium grammar to runtime parsing, linking, validation, and LSP integration.
  • Build-time artifact literacy: Explains how ast.ts, grammar.ts, and module.ts are produced and how they affect runtime behavior.
  • Operational runtime understanding: Details the DocumentState pipeline, scope computation, scope provider/name resolution, and linking/indexing mechanics so you can debug behavior efficiently.
  • Customization patterns: Shows how DI module composition and service overrides change parsing, validation, and IDE features.

Quick Start

Ask an agent to use this guide to explain how a specific Langium DSL file is parsed, linked, validated, and surfaced through LSP in your project.
