This repository documents the work on a proposal for JSON support in the C++ standard library. It follows a previous discussion in the std-proposals forum on the topic.
It's here.
Yes, of course! Have a look at the proposal and open an issue.
No.
We have no idea.
Currently, this is the work of Niels Lohmann and Mario Konrad. We would be happy for any help and feedback we can get.
How is this related to nlohmann/json?
Apparently, Niels is involved in both projects. He is working on the library nlohmann/json for several years now and has been asked on several occasions to write a proposal for the C++ standard library. This proposal surely is inspired by that library, but shall evolve independently from it.
