This package offers a simple way to colorize strings that will be printed into the standard output. Note that Windows is not supported. The available colors are:
Black
Red
Green
Yellow
Blue
Magenta
Cyan
White
Saved
The Saved color asks to preserve the color being used in the console.
Moreover, this packages acknowledges different modes:
Regular
Bold
Underlined
Reversed
In order to use all this, we'll have to create a new Color object. You
usually want to do this with the Default function. This function will build a
new Color object with the default values. With a Color object we can call
the following methods:
// Change the color. The bg parameter asks whether this color has to be
// applied to the background or not.
func (c *Color) Change(color Colors, bg bool)
// Changes the mode for the given one.
func (c *Color) SetMode(m Mode)
// Returns the given string but with the color & mode applied.
func (c *Color) Get(s string) stringFor more information check out the documentation.
package main
import (
"fmt"
"github.com/mssola/colors"
)
func main() {
// By default it respects the current terminal schema.
c := colors.Default()
fmt.Printf(c.Get("Nothing\n"))
// c := colors.Default() is equivalent to:
//
// c := &colors.Color{
// Foreground: colors.Saved,
// Background: colors.Saved,
// Mode: colors.Regular,
// }
//
// You might want to initialize the struct directly if you just want to
// print a colorful message and get out.
// Let's print a red bold message.
c.Change(colors.Red, false)
c.SetMode(colors.Bold)
fmt.Printf(c.Get("Red\n"))
// It will print the same as before but reversed: the background is now red
// and the foreground white.
c.SetMode(colors.Reversed)
fmt.Printf(c.Get("Reversed Red\n"))
