Functions

func ByteArrayToUInt

func ByteArrayToUInt(b []byte) uint64

func CheckRequiredFlag

func CheckRequiredFlag(n, p string)

func CleanLabel

func CleanLabel(value any) string

CleanLabel returns the label value with all special characters replaced with dashes and any character that is not [a-z0-9A-Z] trimmed from start and end. If name is a path only the basename is used.

func EnvDef

func EnvDef(name, def string) string

func First

func First(strs ...string) string

First returns the first non-empty string. If all strings are empty then empty string is returned.
