Colour codes are output to non terminal

[hallzy]

If output of program is redirected to a file for some reason, the colour codes should be suppressed.

This is how I can do the detection:

package main
 
import (
    "os"
    "fmt"
)
 
func main() {
    if fileInfo, _ := os.Stdout.Stat(); (fileInfo.Mode() & os.ModeCharDevice) != 0 {
        fmt.Println("Hello terminal")
    } else {
        fmt.Println("Who are you? You're not a terminal")
    }
}

Just have to adapt that for this code
