lazyjson

JSON parser for golang;

It makes you can use JSON as you do in other Dynamic Programming Languages (like python);

example

this is an example:

	data := `{
		"str_key": "hello",
		"int_key": 2333,
		"float_key": 23.33,
		"bool_key": true,
		"map": {
			"key1": "val1",
			"key2": "val2",
			"arr": [1, 2, 3, 4, 5, 6],
			"map": {
				"key1": "val1",
				"key2": "val2"
			}
		},
		"arr": [
			{
				"key1": "key1"
			},
			{
				"key2": "key2"
			}]
	}`

	var j JSON
	if err := json.Unmarshal([]byte(data), &j); err != nil {
		t.Fatal(err)
	}
	println(j.K("str_key").String(""))
	println(j.K("int_key").Int(0))
	println(j.K("float_key").Float(0))
	println(j.K("bool_key").Bool(false))
	println(j.K("map").K("key1").String(""))
	println(j.K("map").K("arr").I(0).Int(0))
	println(j.K("map").K("map").K("key1").String(""))
	println(j.K("arr").I(0).K("key1").String(""))
	println(j.K("unexisted_key").String("default"))

the output is:

hello
2333
+2.333000e+001
true
val1
1
val1
key1
default

API

type JSON interface {
	// get the value pointed by the key in the JSON map
	K(key string) JSON 

	// get the value pointed by the index in the JSON array
	I(index int) JSON 				
	
	// convert this JSON value to int, return defaultV if failed
	Int(defaultV int) int 			
	
	// convert this JSON value to float, return defaultV if failed
	Float(defaultV float64) float64 
	
	// convert this JSON value to string, return defaultV if failed
	String(defaultV string) string 	
	
	// convert this JSON value to bool, return defaultV if failed
	Bool(defaultV bool) bool
