Overview

This is a very lightweight library for working with JSON type objects in C/C++. It provides a very simpe API to create and manipulate json objects. For now following datatypes or supported -

Primitive data types

 - json_int_t       : int
 - json_uint_t      : unsigned int
 - json_double_t    : double
 - json_string_t    : char *

Complex data types

 - json_object_t    : It can hold key value pairs, where key is a string and
                      value can be any of the json types defined
 - json_array_t     : It can hold any number of elements of any json types

Examples

• JSON Object

Input:

Create a new JSON Object

json_object_t * shape = json_object_new();

Create and add property to this object

json_object_add(shape, "name", json_string_new("Circle"));
json_object_add(shape, "height", json_int_new(100));
json_object_add(shape, "width", json_int_new(200));
json_object_add(shape, "sqrt", json_double_new(20.98));

Create and add another object to the above object

json_object_t * style = json_object_new();
json_object_add(style, "color", json_string_new("red"));

json_object_add(shape, "style", style);

Print above object to console

json_print_pretty(shape);

Finally free all memories

json_destroy(shape);

Output

{
    "name" : "Circle",
    "height" : 100,
    "width" : 200,
    "sqrt" : 20.980000,
    "style" : {
        "color" : "red"
    }
}
