흔히 이렇게 알고 있다

An option configured with an optional value and a custom argParser coerces a fallback value through argParser when the flag is invoked without an argument on the command line.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Option.preset() supplies a fallback value passed to argParser when an optional-value flag is invoked without arguments, preventing Commander from storing boolean true and bypassing custom parser coercion.
• opts() contains boolean true instead of a parsed number when an optional-value option lacks a preset and is passed without an argument
• opts() retains the default value when the optional-value flag is omitted entirely
• opts() contains the parsed custom argument when the flag is passed with an explicit value
• accumulating option collectors append preset values on valueless flag invocations instead of having the entire accumulated array overwritten by boolean true
• options configured with choices validate against preset values rather than assigning boolean true outside the allowed choices list
