The vmblu Playground
The browser-based Playground is itself modeled with vmblu. Its architecture coordinates workspace and document handling, model and Sysblu editing, source navigation, layout, and runtime features while reusing the core and UI libraries shared with the VS Code extension.
The fact that the vscode extension and the playground app could share so many nodes, out of the box, made it a breeze to port the original browser based app to the vscode environment, which is based on a webview, but has a completely different underlying system. Just by introducing a few special nodes we could capture the differences and keep the core vmblu logic untouched.
The entrypoints and implementations are available in the Playground and VS Code webview directories of the vmblu repository.
