Package jsonvalue is for handling unstructured JSON data or customizing JSON marshaling. It is far more faster and convenient than using interface{} with encoding/json.

Please refer to pkg site or wiki for detailed usage and examples.

Especially, please check for jsonvalue's programming scenarios.

Import

Use following statements to import jsonvalue:

import (
	jsonvalue "github.com/Andrew-M-C/go.jsonvalue"
)

Quick Start

Sometimes we want to create a complex JSON object like:

{
  "someObject": {
    "someObject": {
      "someObject": {
        "message": "Hello, JSON!"
      }
    }
  }
}

With jsonvalue, It is quite simple to implement this:

	v := jsonvalue.NewObject()
	v.MustSet("Hello, JSON").At("someObject", "someObject", "someObject", "message")
	fmt.Println(v.MustMarshalString())
	// Output:
	// {"someObject":{"someObject":{"someObject":{"message":"Hello, JSON!"}}}

Similarly, it is quite easy to create sub-arrays like:

[
  {
    "someArray": [
      "Hello, JSON!"
    ]
  }
]
	v := jsonvalue.NewArray()
	v.MustSet("Hello, JSON").At(0, "someObject", 0)
	fmt.Println(v.MustMarshalString())
	// Output:
	// [{"someObject":["Hello, JSON"]}]

In opposite, to parse and read the first JSON above, you can use jsonvalue like this:

	const raw = `{"someObject": {"someObject": {"someObject": {"message": "Hello, JSON!"}}}}`
	s := jsonvalue.MustUnmarshalString(s).GetString("someObject", "someObject", "someObject", "message")
	fmt.Println(s)
	// Output:
	// Hello, JSON!

However, it is quite complex and annoying in automatically creating array. I strongly suggest using SetArray() to create the array first, then use Append() or Insert() to set array elements. Please refer go godoc or Wiki.
