README

pp Go Go Reference

Colored pretty printer for Go language

Usage

Just call pp.Print().

import "github.com/k0kubun/pp/v3"

m := map[string]string{"foo": "bar", "hello": "world"}
pp.Print(m)

API

fmt package-like functions are provided.

pp.Print()
pp.Println()
pp.Sprint()
pp.Fprintf()

See the documentation for API details.

Configuration

They can be customized globally with pp.Default.

pp.Default.SetColoringEnabled(false)
pp.Println() // no color

You can also create individual instances that do not interfere with the default printer:

mypp := pp.New()
mypp.SetColoringEnabled(false)
mypp.SetExportedOnly(true)
mypp.Println()

See PrettyPrinter documentation for all available configurations.

Custom colors

If you require, you may change the colors (all or some) for syntax highlighting:

// Create a struct describing your scheme
scheme := pp.ColorScheme{
    Integer:       pp.Green | pp.Bold,
    Float:         pp.Black | pp.BackgroundWhite | pp.Bold,
    String:        pp.Yellow,
}

// Register it for usage
pp.Default.SetColorScheme(scheme)

Look into ColorScheme struct for the field names.

If you would like to revert to the default highlighting, you may do so by calling pp.ResetColorScheme().

Out of the following color flags, you may combine any color with a background color and optionally with the bold parameter. Please note that bold will likely not work on the windows platform.
