Is gdnative_api.json manually ou programmatically generated?

I am studying a way to implement the missing built-in methods discussed in this thread. godotengine/godot-cpp#107

The JSON is written manually, but not in this repo. It's copied here from modules/gdnative in the main Godot repository.

The math functions and similar low-level ones shouldn't be added this way, since the C interface prevents inlining them. It's better to use the ones provided by the binding language's standard library. Some of the others are member functions of the relevant classes (JSON, Dictionary, Variant, ...). There might be a few important ones still missing that would be worth adding though

I found a easier way, I just clone the engine source and add it to my include path, I tested clamp and Math::angle_lerp and both has worked so far.
