goLang debugging through JSON MarshalIndent

gistfile1.txt

// IMPORTANT!!! You need to export the T1.id field so that the json package can see it. Rename the name field to Id.

package main

import (
	"encoding/json"
	"fmt"
	"reflect"
)

func myDebug(s string, i interface{}) {
	pretty, err := json.MarshalIndent(i, "", "  ")
	if err != nil {
		fmt.Println("error:", err)
	}
	fmt.Printf("\n\nmyDebug: %s (%s) => %s\n", s, reflect.TypeOf(i).String(), string(pretty))

	fmt.Printf("\n\nmyDebugPlain: %+v\n", i)
}

type M map[string]interface{}

type T1 struct {
	Id    int
	Texto string
}

type T2 struct {
	Id    int
	Texto string
	Mapas []M
}

func main() {
	tm := make(M)
	tm["fruta"] = "manzana"
	tm["verdura"] = "coliflor"

	tm2 := make(M)
	tm2["planas"] = "lentejas"
	tm2["redondas"] = "garbanzos"

	myDebug("tm", tm)
	myDebug("tm2", tm2)

	tm["legumbre"] = tm2

	myDebug("tm", tm)

	var tm3 T2
	tm3.Id = 11
	tm3.Texto = "hello world"

	myDebug("tm3", tm3)

	tm3.Mapas = append(tm3.Mapas, tm)

	myDebug("tm3", tm3)

	tm4 := T1{12, "hi"}
	myDebug("tm4", tm4)
