## cjson

wrap cJSON for vlang.

V already has the standard json module base on cJSON,but only public json.encode() and json.decode(). 

sometimes we may need to use [cJSON](https://github.com/DaveGamble/cJSON) directly.

## Installation

- via vpm

  ```

  v install lydiandy.cjson

  ```

- via source

  ```

  git clone [email protected]:lydiandy/cjson.git

  ln -s your/path ~/.vmodules/cjson

  ```

## usage

```v

module main

import cjson  // import lydiandy.cjson

struct User {

	name string

	age  int

}

fn main() {

	// cjson print

	u := User{name:'tom', age:18}

	root := cjson.create_object()

	cjson.add_item_to_object(root, "name", cjson.create_string(u.name))

	cjson.add_item_to_object(root, "age", cjson.create_number(u.age))

	json_str := cjson.json_print(root)

	println(json_str)

	// cjson parse

	json_content:='{"name":"jack","age":22}'

	res := cjson.json_parse(json_content)

	

	name := cjson.get_object_item(res, 'name')

	age := cjson.get_object_item(res, 'age')

	println(name.valuestring)

	println(age.valueint)

	// simple way to use cjson

	simple_example()

}

fn simple_example() {

	println('======== simple print json =========')

	user := cjson.obj()

	user.set("name", cjson.str("Tom"))

	user.set("age", cjson.num(18))

	user.set("score", cjson.num(6.2))

	user.set("gender", cjson.boolean(true))

	user.set("password", cjson.null())

	friend := cjson.obj()

	friend.set("name", cjson.str("Jack"))

	friends := cjson.list()

	friends.add(friend)

	user.set("friends", friends)

	leader := cjson.obj()

	leader.set("name", cjson.str("Mike"))

	user.set("leader", leader)

	json_str := user.dump()

	println(json_str)

	println('======== simple parse json =========')

	json_content := '{

        "name": "Tom",

        "age": 18,

        "score": 6.2,

        "gender": true,

        "password": null,

        "friends": [{

			"name": "Jack"

		}],

        "leader": {

			"name": "Mike"

        }

	}'

	obj := cjson.load(json_content)

	println(obj.get_str("name"))

	println(obj.get_int("age"))

	println(obj.get_num("score"))

	println(obj.get_boolean("gender"))

	println(obj.is_null("password"))

	println(obj.get("leader").get_str("name"))

}
