How Can I Pretty-Print Variables in Go Like Ruby's `awesome_print`?

Printing Variables with Style in Go

Ruby's awesome_print Equivalent in Go

In Ruby, awesome_print provides a clean and structured way to display variables. Is there something similar in Go?

Solution

While there's no built-in equivalent, the json.MarshalIndent function offers a reasonable option.

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

This will print the variable x as a formatted JSON string:

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

This solution does not require third-party packages, making it suitable for situations where external dependencies are undesirable.
