Functions

func AskForConfirmation

func AskForConfirmation(NoPrompt bool, msg string) bool

AskForConfirmation uses Scanln to parse user input. A user must type in "yes" or "no" and then press enter. It has fuzzy matching, so "y", "Y", "yes", "YES", and "Yes" all count as confirmations. If the input is not recognized, it will ask again. The function does not return until it gets a valid response from the user. Typically, you should use fmt to print out a question before calling AskForConfirmation. E.g. fmt.Println("WARNING: Are you sure? (yes/no)")
