Readonly MoonBit Viewer

This repository has two main parts:

• viewer: the reusable MoonBit readonly viewer. It is Monaco-shaped in API and behavior where that helps embedders, but it stays MoonBit-owned and does not import Monaco, VS Code, or CodeMirror code.
• internal/shell: the reference app/backend used to see the viewer working against a real workspace. It demonstrates one host composition and must use the viewer through public APIs; it is not an external import surface.

Monaco/VS Code is the primary design reference. CodeMirror is a secondary reference when its simpler state/view split is useful. Both submodules are reference-only.

Quick Start

npm install
just check
just build
just dev ROOT=. PORT=5173

Open http://127.0.0.1:5173/. The dev server is the internal native backend shell: it serves web/dist and talks to the browser workbench over the readonly remote protocol WebSocket.

Validation

just check
just test
just build
just test-browser

Current architecture lives in docs/architecture.md. Browser harness behavior lives in docs/harness.md.
