Abstract Value Members

  1. abstract def read(a: String): Result[A]

    Either convert the string to A or return a failure message.

    Either convert the string to A or return a failure message.

    Note that throwing an exception from a reader will cause the parser to crash, leading to a horrible user experience.

  2. abstract def show(a: A): String

    Show a given value as a string.

    Show a given value as a string. This is used in help dialogs to display default values.
