nlohmann/json

[thomassuckow]

nlohmann/json is configured to use an import of #include <json/json.hpp> where the documentation for the project and other package managers use #include <nlohmann/json.hpp>

Furthermore, the version should be updated from 2.1.1 to the current 3.1.2.

[nikhedonia]

updated the package. Thanks for your patience.

@nikhedonia Thanks a lot. But how can I use the 3.1.2 version?

I tried

buckaroo quickstart 
buckaroo install nlohmann/json

and then used the following buckaroo_example/main.cpp file:

#include <nlohmann/json.hpp>
#include <iostream>

using json = nlohmann::json;

int main()
{
    std::cout << json::meta() << std::endl;
}

But buck run :main failed with

buck run :main

I would really like to have a small running example for my documentation.
