JSON Manipulation Header-only Library for C++

Trivially create and manipulate JSON with one header

#include <json.h>

int main() {
  json record;

  record["projects"]["json"]["year"] = 2017;                         // value of type integer
  record["projects"]["json"]["url"] = "https://json.org";            // value of type string
  record["projects"]["json"]["commits/day"] = 5.21;                  // value of type double
  record["projects"]["json"]["cool?"] = true;                        // value of type bool

  record["projects"]["llama"]["language"] = "C++";
  record["projects"]["llama"]["domain"] = "Linear Algebra";
  record["projects"]["llama"]["url"] = nullptr;                      // value of type null

  record["projects"]["rosmod"]["language"] = "C++/Python";
  record["projects"]["rosmod"]["url"] = "https://github.com/rosmod";
  record["projects"]["rosmod"]["active?"] = false;

  auto keys = record["projects"]["json"].keys();                     // ["year", "url", "commits/day"]
  auto query = record["projects"]["json"]["commits/day"].value();    // query = "5.21"
  
  std::string record_string = record.to_string();                    // returns a string of the json
  record.print();                                                    // pretty prints json data
  record.write("record.json");                                       // writes json to file
}

Pretty JSON is pretty!

{
    "projects" :
    {
        "json" :
        {
            "commits/day" : 5.21,
            "is this cool?" : true,
            "url" : "https://json.org",
            "year" : 2017
        },
        "llama" :
        {
            "domain" : "Linear Algebra",
            "language" : "C++",
            "url" : null
        },
        "rosmod" :
        {
            "active?" : false,
            "language" : "C++/Python",
            "url" : "https://github.com/rosmod"
        }
    }
}
