Simple Go dump function for struct slices variables (WIP) https://play.golang.org/p/KxpMJdFSDkI

debug.go

package main

import (
	"fmt"
)

type (
	Author struct {
		Name   string
		Email  string
		Status bool
	}
)

func dump(authors []Author, msg string) {
	fmt.Printf("Dumping variables\nType: %T\nMessage: %s\n", authors, msg)
	fmt.Println("---------------")

	for i, author := range authors {
		fmt.Printf(
			"%o. | %s %v | %s %v | %s %v | \n",
			i, "Name:", author.Name, "Email:", author.Email, "Status:", author.Status,
		)
	}

	fmt.Println("")
}

func main() {
	var authors = []Author{
		{Name: "Jose Quintana", Email: "jq@system.local", Status: true},
		{Name: "Tux Linux", Email: "tl@system.local", Status: false},
	}

	dump(authors, "Optional description...")

	// Output:
	//
	// Dumping variables
	// Type: []main.Author
	// Message: Optional description...
	// ---------------
	// 0. | Name: Jose Quintana | Email: jq@system.local | Status: true |
	// 1. | Name: Tux Linux | Email: tl@system.local | Status: false |
