json's Introduction

json

!WARNING! This repository moved and maintained here: https://github.com/infiniteloopcloud/json

Copy of Golang's json library with IsZero feature from CL13977

Disclaimer

It is a package primary used for my own projects, I will keep it up-to-date with the mainline versioning of Go.

Usage

Exactly the same as Go's JSON. Plus...

package main

import (
	"encoding/json"
	"fmt"
)

type nullString struct {
	Valid  bool
	String string
}

func (n nullString) IsZero() bool {
	return !n.Valid
}

type RandomDataSet struct {
	Data1 nullString `json:"data1,omitempty"`
	Data2 nullString `json:"data2,omitempty"`
}

func main() {
	result, err := json.Marshal(RandomDataSet{Data1: nullString{Valid: true, String: "test"}})
	if err != nil {
		panic(err)
	}
	fmt.Println(string(result))
}

// Output: {"data1":{"Valid":true,"String":"test"}}

json's Issues

PodTemplateSpec in k8s print "null" values for keys 

package main

import (
  "fmt"
  "github.com/PumpkinSeed/json"
  v1 "k8s.io/api/core/v1"
)
func main() {
  spec := v1.PodTemplateSpec{
    Spec: v1.PodSpec{
      Containers: []v1.Container{
        {
          Name: "sample",
        },
      },
    },
  }
  out, _ := json.Marshal(spec)
  fmt.Println(string(out))
}

Output:

{"metadata":{"creationTimestamp":null},"spec":{"containers":[{"name":"sample","resources":{}}]}}

How do I resolve this to not print "null" valued keys?

Ref: PodTemplateSpec

Does this work only if the struct implements IsZero() function?
