Simple golang expirement with ANSI colors

colors.go

package main
// http://play.golang.org/p/jZ5pa944O1 <- will not display the colors
import "fmt"

const (
        InfoColor    = "\033[1;34m%s\033[0m"
        NoticeColor  = "\033[1;36m%s\033[0m"
        WarningColor = "\033[1;33m%s\033[0m"
        ErrorColor   = "\033[1;31m%s\033[0m"
        DebugColor   = "\033[0;36m%s\033[0m"
)

func main() {
        fmt.Printf(InfoColor, "Info")
        fmt.Println("")
        fmt.Printf(NoticeColor, "Notice")
        fmt.Println("")
        fmt.Printf(WarningColor, "Warning")
        fmt.Println("")
        fmt.Printf(ErrorColor, "Error")
        fmt.Println("")
        fmt.Printf(DebugColor, "Debug")
        fmt.Println("")

}

None of this seems to work for me. (I'm on a Windows 10 computer using go1.15.5 windows/amd64)

try on win10 terminal ?

the following link writes that in order to enable colors in Windows terminal you need to change the registry a bit:

HKEY_CURRENT_USER\Console\VirtualTerminalLevel
"VirtualTerminalLevel"=dword:00000001

Rainbow Console Text:

package main

import (
	"fmt"
	"math/rand"
	"os"
	"time"
)

func rainbow(i string, timeout int) {
	colors := []string{
		"\033[;31m",
		"\033[;34m",
		"\033[;32m",
		"\033[;35m",
		//Add more if needed
	}
	for {
		n := rand.Int() % len(colors)
		fmt.Printf("\r%s%s", colors[n], i)
		os.Stdout.Sync()
		time.Sleep(time.Millisecond * time.Duration(timeout))
	}

}
func main() {
	rainbow("Text", 300) // Text | Timeout
}

@zaydek-old in case you're colorblind and didn't know, your colors are wrong. See the original post for correct colors.

Thank you. Very helpful for go test. Anything that fails prints Red so I can easily spot it. (on Linux)
