TypeMF Runtime

The shared runtime for TypeMF extensions in VS Code. It holds one package registry and one instance of every shared module, so that all TypeMF extensions in a window work on the same metamodels and the same classes.

You normally don't install this extension yourself: extensions that need it, such as the TypeMF Instance Editor, list it as a dependency and VS Code installs it with them.

This extension is a preview. Its API may still change before 1.0.

What it provides

• The TypeMF libraries @typemf/core, @typemf/xmi, @typemf/json and @typemf/node as shared modules.
• A shared EPackage registry, resource factory registry (XMI, Ecore, JSON) and URI converter registry (file: URIs).
• Model packages provided by other extensions, loaded on first use.
• Metamodels from .ecore files listed in the typemf.ecoreMappings setting.

Settings

typemf.ecoreMappings registers .ecore files as metamodels at startup. Paths are resolved relative to the first workspace folder. Entries from user, workspace and folder settings are merged; for the same nsURI the most specific one wins.

"typemf.ecoreMappings": [
  { "nsURI": "https://example.org/library", "ecoreFile": "model/library.ecore" }
]

For extension authors

Use the npm package @typemf/vscode-runtime to access the runtime from your extension or to provide your own model package.
