Class Method Details

.add_supported_algorithms_as_options! ⇒ Object

An option will be made for every element in Digest::SUPPORTED_ALGORITHMS. They may be used together and always append to the function array, bound to the :functions key.

However, due to the lack of a formally defined functions option, the Acclaim option parser will not set that option to anything. Therefore, calling options.functions will return an empty ribbon if the user doesn’t specify any functions on the command line.

options.functions? should ALWAYS be called, preferably while providing an empty array as fallback.
