Struct flagValueWrapper

golangflag.go:27–30

flagValueWrapper implements pflag.Value around a flag.Value. The main difference here is the addition of the Type method that returns a string name of the type. As this is generally unknown, we approximate that with reflection.

// name of the type.  As this is generally unknown, we approximate that with
// reflection.
type flagValueWrapper struct {
	inner    goflag.Value
	flagType string
}

// We are just copying the boolFlag interface out of goflag as that is what
// they use to decide if a flag should get "true" when no arg is given.
