rune-langium

Use this router when the task spans the monorepo or you are not yet sure which package owns the behavior.

Route by task

1. Parsing, ASTs, serializers, or .rosetta validation → rune-langium-core
2. CLI commands or terminal workflows → rune-langium-cli
3. Language-server integration, WebSocket LSP, diagnostics, hover, or completion → rune-langium-lsp-server
4. Code generation, preview schemas, or exported source maps → rune-langium-codegen
5. Graph rendering, React Flow nodes, layout, or visual-editor state → rune-langium-visual-editor

Quick package guide

core → rune-langium-core

• Parse a single file or a full workspace
• Validate cross-file references
• Serialize models back to Rune/Rosetta text

cli → rune-langium-cli

• Run the rune-dsl command
• Wire parser/codegen flows into shell scripts or local tooling

lsp-server → rune-langium-lsp-server

• Embed or host the Rune DSL language server
• Bridge Monaco/CodeMirror/browser editors to LSP features

codegen → rune-langium-codegen

• Generate derived artifacts from parsed documents
• Build or consume form-preview schemas and code-preview source maps

visual-editor → rune-langium-visual-editor

• Render and interact with Rune graphs in React
• Work on node rendering, layout, or store behavior

Rules

• Do not load every package skill at once; start with the owning package.
• If a task crosses package boundaries, begin with the foundational package and then move outward.
