Peterjsons helps dealing with random json input when the usecase is a transformation to another json output. It receives a random json input and a json recipe to "cook" the json output.

How to install:

go get github.com/stacknowledge/peterjsons

How to use:

package main

import (
	"fmt"

	"github.com/stacknowledge/peterjsons"
)

func main() {
	material := []byte(`
            {
                "info" : {
                    "peter":"jsons"
                }
            }
        `)

	recipe := []byte(`
            {
                "recipe": {
                    "id" : "info.peter"
                }
            }
        `)

    pjsons, err := peterjsons.New(material, recipe)
	if err != nil {
		fmt.Printf("\n %s \n", err)
    }
    
	pjsons.Cook()

    fmt.Printf("\n %s \n", pjsons.JSONResult())

    // ------------------------------------------------
    //             Outputs : {"id":"jsons"}
    // ------------------------------------------------
}
