[Question] How to use Z{f(x)} (runtime execution engine) without the UI or Editor?

[KrishnaPG]

This project looks great. Is there a way the backend runtime (the node-graph execution engine) can be embedded in other C++ applications?

For example, let us say a node-graph (sequence of nodes) is created and saved as a file using the Zeno UI/Editor. Would like some other application to load that saved node-graph file and run it (by instantiating it with input params/data retrieved from network or database).

It seems the Zeno is built as a library (.lib file) - but it is not clear how to embed the runtime into other C++ applications and launch the node-graph runner.

Is there any example that demonstrates this? i.e. embedding the runtime engine in external applications (without having to use the UI/Editor). It would be of great help. Thank you.

Of course! See: https://github.com/zenustech/zeno_embed_demo It runs without Python and Qt, directly in an OpenGL application. It uses the exported json-alike file my_zeno_scene.h, which can be exported in File -> Export. You may need to use the commit at external/zeno since it's been long not updated though. We also succeed in embedding it into an Android application too, although it's not open-source yet.

Thank you @archibate

Unfortunately encountering many build errors due to C++17 not having std::unary_function etc.
