type OptionalBool

type OptionalBool struct {
	IsSet bool
	Value bool
}

OptionalBool is an bool flag that lets you to tell if the flag has been set or not, unlike flag.BoolVar(), which does not.

OptionalBool can distinguish between all three of these conditions:

$ prog -bool=true
$ prog -bool=false
$ prog

OptionalBool supports, but can not distinguish, this additional condition:

$ prog -bool

Like flag.BoolVar(), OptionalBool does not support these conditions:

$ prog -bool true
$ prog -bool false

}

OptionalFloat64 is a float64 flag that lets you to tell if the flag has been set or not, unlike flag.Float64Var(), which does not.

OptionalFloat64 can distinguish between all three of these conditions:

$ prog -float64 1.1
$ prog -float64 0
$ prog
