Functions

func ConfirmAction

func ConfirmAction(actionText string, deniedText string) (bool, error)

ConfirmAction uses the passed in actionText as the confirmation text displayed in the terminal. The user must enter Y or N to indicate whether they confirm the action detailed in the warning text. Returns a boolean representing the user's answer.

func DefaultDataDir

func DefaultDataDir() string

DefaultDataDir is the default data directory to use for the databases and other persistence requirements.

func WrapFlags

func WrapFlags(flags []cli.Flag) []cli.Flag

WrapFlags so that they can be loaded from alternative sources.
