How to pretty print variables

Question

Is there something like Ruby's awesome_print in Go?

For example in Ruby you could write:

require 'ap' x = {a:1,b:2} // also works for class ap x 

the output would be:

{    "a" => 1,   "b" => 2 } 

closest thing that I could found is Printf("%#v", x)

Answer 1

If your goal is to avoid importing a third-party package, your other option is to use json.MarshalIndent:

x := map[string]interface{}{"a": 1, "b": 2} b, err := json.MarshalIndent(x, "", "  ") if err != nil {     fmt.Println("error:", err) } fmt.Print(string(b)) 

Output:

{     "a": 1,     "b": 2 }
