jaason: Easy to use json library for Go without defining struct.

About

jaason is a library to use json format in Golang without defining struct. It is simple and easy to use. Inspired by github.com/antonholmqist/jason

Usage

go get github.com/aimof/jaason

import "gighub.com/aimof/jaason"

Example

package main

import (
	"fmt"
	"log"

	"github.com/aimof/jaason"
)

const j = `{
	"object1": {
		"string0": "string0",
		"number0": 0,
		"bool0": true,
		"null0": null
	},
	"array0": [
		1.2,
		true,
		"2"
	]
}`

func main() {
	rootObject, err := jaason.Parse([]byte(j))
	// handle error

	s, err := rootObject.Get("object1").Get("string0").String()
	// handle error
	fmt.Printf("%s\n", s) // string0

	f, err := rootObject.Get("array0").Get(0).Float64()
	// handle error
	fmt.Printf("%.1f\n", f) // 1.2
}

Usage

tyep Value

type Value struct {
    // contains filtered or unexported fields
}

Value is a parsed JSON value. It may be an object, array, boolean, number, string or null.

Parse

func Parse(b []byte) (*Value, error)

Parse JSON formatted bytes to *Value.

Get

func (*Value) Get(interface{}) *Value

Get function is like JS code below.

object["key"]
array[0]

When Get from Value with key or index, it returns the value.

The parameter must be a string or a int.

Get doesn't return error. It has errors in value. IT returns errors when calls functions below.

type functions

Get returns type *jaason.Value so you must use these functions.

func (*Value) Bool() (bool, error)
func (*Value) Int() (int, error)
func (*Value) String() (string, error)
func (*Value) IsNull() (bool, error)

ToDo

• func (*Value) Err() error.
• Write more test cases.
• Write more README.md.
• Define errors.
