# JSon-library
### JSon-library supports 6 data types:
```
null
boolean
integer
string
object
array
```
### Easy to use:
#### json object:
```
#include
...
json_object_t *jo = json_object_create(); // create
json_object_put_null(jo, "null_key");
json_object_put_bool(jo, "bool_key", 0);
json_object_put_int(jo, "int_key", 144);
json_object_put_string(jo, "string_key", "hello world!");
json_object_get_size(jo); // return 4
json_object_has(jo, "unexist_key"); // return 0
json_object_has(jo, "bool_key"); // return 1
json_object_is_null(jo, "null_key"); // return 0
json_object_is_null(jo, "string_key"); // return 1
json_object_get_int(jo, "int_key"); // return 144
json_object_put_int(jo, "int_key", 0);
json_object_get_size(jo); // return 4
json_object_get_int(jo, "int_key"); // return 0
json_object_remove(jo, "int_key");
json_object_get_size(jo); // return 3
json_object_to_string(jo); // return {"null_key":null, "bool_key":false, "string_key":"hello world!"}
json_object_t *jo2 = json_object_create_from_string("{\"null_key\":null, \"bool_key\":false, \"string_key\":\"hello world!\"}"); // `\"` because " is an escape char
// jo content is completly equal to jo2 content
json_object_destroy(jo); // destroy and return NULL
json_object_destroy(jo2);
```
#### json array:
```
#include
...
json_array_t *ja = json_array_create(); // create
json_array_put_int(ja, 0);
json_array_put_int(ja, 2);
json_array_put_object_at(ja, 1, json_object_create());
json_array_get_size(ja); // return 3
json_array_to_string(ja); // return [0, {}, 2]
json_object_put_null(json_array_get_object(ja, 1), "null_key");
json_array_to_string(ja); // return [0, {"null_key":null}, 2]
json_array_remove(ja, 2);
json_array_put_array_at(ja, 1, json_array_clone(ja));
json_array_to_string(ja); // return [0, [0, {"null_key":null}], {"null_key":null}]
json_array_destroy(ja); // destroy and return NULL
```
