C++ compatible Ink library

Any suggestions how to use Ink and a native c++ engine?

I imagined porting https://github.com/premek/pink to c++ via https://github.com/yhirose/cpp-peglib.

Any other ideas?

The game engine is Godot Engine, but I don't use C#. https://github.com/paulloz/godot-ink and it prevents exports to html5 and mobile devices.
