Package ansi is a small, fast library to create ANSI colored strings and codes.

Install

This install the color viewer and the package itself

go get -u github.com/mgutz/ansi/cmd/ansi-mgutz

Example

import "github.com/mgutz/ansi"

// colorize a string, SLOW
msg := ansi.Color("foo", "red+b:white")

// create a closure to avoid recalculating ANSI code compilation
phosphorize := ansi.ColorFunc("green+h:black")
msg = phosphorize("Bring back the 80s!")
msg2 := phospohorize("Look, I'm a CRT!")

// cache escape codes and build strings manually
lime := ansi.ColorCode("green+h:black")
reset := ansi.ColorCode("reset")

fmt.Println(lime, "Bring back the 80s!", reset)

Other examples

Color(s, "red+u")          // red underline
Color(s, "red+bh")         // red bold bright
Color(s, "red:white")      // red on white
