Colors (Issue copied from the archived project)

[WarpRat]

I came across this issue while googling for something similar. As the readme in both projects says, these projects directly track the upstream internal package which the Go authors have decided they will not move to a non-internal path. @victorboissiere I assume you've already solved this issue but for anyone else who may stumble across this, this is easy to impliment yourself with a small function to color the diff:

func colorDiff(diffs string) string {
	green := "\x1b[32m"
        // green := "\x1b[48;5;194m" // if you prefer a light green background
	red := "\x1b[31m"
        // red := ""\x1b[48;5;210m" // if you prefer a light red/pink background
	reset := "\x1b[0m" // Reset to default terminal colors

	var colorDiff strings.Builder
	lines := strings.Split(diffs, "\n")
	for _, line := range lines {
		if len(line) > 0 {
			switch string(line[0]) {
			case "-":
				colorDiff.WriteString(red + line + reset + "\n")
			case "+":
				colorDiff.WriteString(green + line + reset + "\n")
			default:
				colorDiff.WriteString(line + "\n")
			}
		} else {
			colorDiff.WriteString(line + "\n")
		}
	}

	return colorDiff.String()
}
