add off to disable colors
Package ansi is a small, fast library to create ANSI colored strings and codes.
This install the color viewer and the package itself
go get -u github.com/mgutz/ansi/cmd/ansi-mgutz
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") // red Color(s, "red+b") // red bold Color(s, "red+B") // red blinking Color(s, "red+u") // red underline Color(s, "red+bh") // red bold bright Color(s, "red:white") // red on white Color(s, "red+b:white+h") // red bold on white bright Color(s, "red+B:white+h") // red blink on white bright Color(s, "off") // turn off ansi codes
