ansi

ansi contains a bunch of constants and possibly additional terminal related functionality in the future.

Why another ANSI library?

I already had the ANSI escape sequences the way I want them, but was repeating the same code in multiple projects and so created this to stop that; it solves nothing new.

Installation

Use go get

go get -u github.com/go-playground/ansi/v3

Usage

package main

import (
	"fmt"

	"github.com/go-playground/ansi/v3"
)

// make your own combinations if you want
const blinkRed = ansi.Red + ansi.Blink + ansi.Underline

func main() {

	// Foreground
	fmt.Printf("%s%s%s\n", ansi.Black+ansi.GrayBackground, "testing foreground", ansi.Reset)
	fmt.Printf("%s%s%s\n", ansi.Gray, "testing foreground", ansi.Reset)
