For developers familiar with Ruby's awesome_print, finding a similar solution in Go can be daunting. This article explores how to achieve pretty printing of variables in Go. Let's dive into it.
While Go does not offer a built-in equivalent to Ruby's awesome_print, there are a couple of options to consider:
This approach involves using the json.MarshalIndent function:
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 produce the following output:
{ "a": 1, "b": 2 }
It's a straightforward method that doesn't require any external dependencies.
If you're willing to import a third-party package, you can use gorilla/pp. This package provides a variety of options for pretty printing:
import "github.com/gorilla/pp"
x := map[string]interface{}{"a": 1, "b": 2} pp.Print(x) // Output to stdout
This package offers more advanced formatting options, making it a suitable choice for complex printing scenarios.
Based on your specific needs, you can choose the option that best fits your project and printing requirements in Go.
