Towards a Graphical Language Server Protocol for Diagrams?
summary
Proof‑of‑concept implements a graphical LSP by extending Sprotty with a Java server framework and a TypeScript client, reusing Theia/LSP plumbing. It ships a protocol for create/move/connect operations, a palette, and drag-and-drop pins that describe valid moves so the client gives local feedback. The server owns the model, applies changes, enforces constraints and can reject edits; demo shows client rendering updates and server‑side rejection working end to end.
