JsonPack

JsonPack is a high-performance and extremely easy-to-use JSON serialization library for C++ 11, it provide a absolute abstraction layer of this Data Interchange Format. From now on, you only should take care about managing your C++ objects and JsonPack will make the rest.

• Easy-to-use, contains a very short and intuitive API. See Example section

• Very fast, zero string copy and fast number conversions.

• Support serialization/deserialization for c++ types: bool, char, int, unsigned int, long, unsigned long, float, double, std::string and char*.

• Support serialization/deserialization for c++ standard containers: array, vector, deque, list, forward_list, set, multiset, unordered_set, unordered_multiset.

• Parsing error management

• JSON keys match with C++ identifiers name convention.

struct  DataObject
{
    int mInt = 0;
    float mFloat = 0.0;
    std::string mCad = "";
    bool isObject = true;
    char caracter = 0;
    char *cstr = (char*)"Hello world";

    // The defined members, will be the JSON attributes set
    // Pairs <"key" : value>, are: <"member-name" : member-value >
    DEFINE_JSON_ATTRIBUTES(mFloat, mInt, mCad, isObject, caracter, cstr)
};

int main()
{

    // manage my object
    DataObject src, out;

    src.mFloat = 3.1415926535897932384626433832795;
    src.mInt = 362880;
    src.mCad = "This is a test";
    src.isObject = true;
    src.caracter = '$';

    //serialize object
    char* serialized = src.json_pack();
    printf("json: \n%s\n", serialized);

    //deserialize json
    try
    {
      out.json_unpack(serialized, strlen(serialized) );
      printf("\nobject: \nout.mFloat=%0.16f\nout.mInt=%d\nout.mCad=%s\nout.isObject=%d\nout.caracter=%c\ncstr=%s\n",
              out.mFloat, out.mInt, out.mCad.data(), out.isObject, out.caracter, out.cstr
             );
    }
    catch (jsonpack::jsonpack_error &e)
    {
        printf("error: %s\n", e.what());
    }


    free(serialized);
    getchar();

    return 0;
}
