A Json object represents any JSON +value: null, bool, number (int or double), string (std::string), array (std::vector), or +object (std::map). + +Json objects act like values. They can be assigned, copied, moved, compared for equality or +order, and so on. There are also helper methods Json::dump, to serialize a Json to a string, and +Json::parse (static) to parse a std::string as a Json object. + +It's easy to make a JSON object with C++11's new initializer syntax: + + Json my_json = Json::object { + { "key1", "value1" }, + { "key2", false }, + { "key3", Json::array { 1, 2, 3 } }, + }; + std::string json_str = my_json.dump(); + +There are also implicit constructors that allow standard and user-defined types to be +automatically converted to JSON. For example: + + class Point { + public: + int x; + int y; + Point (int x, int y) : x(x), y(y) {} + Json to_json() const { return Json::array { x, y }; } + }; + + std::vector<Point> points = { { 1, 2 }, { 10, 20 }, { 100, 200 } }; + std::string points_json = Json(points).dump(); + +JSON values can have their values queried and inspected: + + Json json = Json::array { Json::object { { "k", "v" } } }; + std::string str = json[0]["k"].string_value(); + +More documentation is still to come.
