• This action is very slow, especially on Windows, see issue #36.
• Macos runners are not supported, because OpenModelica discontinued the Mac builds after version 1.16. It should be possible to build/install latest OpenModelica nightly for macOS, see this README.
• OPENMODELICA home environment variable is only set on Windows. If you need it on Linux as well open an issue.

There is a dockerfile in .ci/dockerfile one can use for developing on Windows 10, so the installer won't mess with the host system.

To build and test run:

$ npm install
$ npm run build
$ npm run package
$ npm test

This package was developed as part of the Proper Hybrid Models for Smarter Vehicles (PHyMoS) project, supported by the German Federal Ministry for Economic Affairs and Climate Action with project number 19|200022G.
