Method: Beaker::Options::Parser#split_arg

Defined in:
lib/beaker/options/parser.rb

#split_arg(arg) ⇒ Array

Normalizes argument into an Array. Argument can either be converted into an array of a single value, or can become an array of multiple values by splitting arg over ‘,’. If argument is already an array that array is returned untouched.

Examples:

split_arg([1, 2, 3]) == [1, 2, 3]
split_arg(1) == [1]
split_arg("1,2") == ["1", "2"]
split_arg(nil) == []

Parameters:

  • arg (Array, String) —

    Either an array or a string to be split into an array

Returns:

  • (Array) —

    An array of the form arg, [arg], or arg.split(‘,’)
