Method Show

interactive_confirm_printer.go:109–166

Show shows the confirm prompt. Example: result, _ := pterm.DefaultInteractiveConfirm.Show("Are you sure?") pterm.Println(result)

(text ...string)

//	result, _ := pterm.DefaultInteractiveConfirm.Show("Are you sure?")
//	pterm.Println(result)
func (p InteractiveConfirmPrinter) Show(text ...string) (bool, error) {
	// should be the first defer statement to make sure it is executed last
	// and all the needed cleanup can be done before
	cancel, exit := internal.NewCancelationSignal(p.OnInterruptFunc)
	defer exit()

	var result bool

	if len(text) == 0 || text[0] == "" {
		text = []string{p.DefaultText}
	}

	p.TextStyle.Print(text[0] + " " + p.getSuffix() + p.Delimiter)
	y, n := p.getShortHandles()

	var interrupted bool

		key := keyInfo.Code
		char := strings.ToLower(keyInfo.String())
		if err != nil {
