Internals
An option modifier.
Option modifiers are values that represent a modification of the properties of an option.
The type parameter a is the return type of the option, while f is a
record containing its properties (e.g. OptionFields for regular options,
FlagFields for flags, etc...).
An option modifier consists of 3 elements:
- A field modifier, of the form
f a -> f a. These are essentially (compositions of) setters for some of the properties supported byf. - An optional default value and function to display it.
- A property modifier, of the form
OptProperties -> OptProperties. This is just like the field modifier, but for properties applicable to any option.
Modifiers are instances of Monoid, and can be composed as such.
One rarely needs to deal with modifiers directly, as most of the times it is
sufficient to pass them to builders (such as strOption or flag) to
create options (see Builder).
