json11

------

json11 is a tiny JSON library for C++11, providing JSON parsing and serialization.

The core object provided by the library is json11::Json. 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 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();
