Golang Color.Println Examples

Example #1

File: console.go Project: fwessels/mc

// consolePrintln - same as print with a new line.
func consolePrintln(tag string, c *color.Color, a ...interface{}) {
	privateMutex.Lock()
	defer privateMutex.Unlock()

	switch tag {
	case "Debug":
		// if no arguments are given do not invoke debug printer.
		if len(a) == 0 {
			return
		}
		output := color.Output
		color.Output = stderrColoredOutput
		if isatty.IsTerminal(os.Stderr.Fd()) {
			c.Print(ProgramName() + ": <DEBUG> ")
			c.Println(a...)
		} else {
			fmt.Fprint(color.Output, ProgramName()+": <DEBUG> ")
			fmt.Fprintln(color.Output, a...)
		}
