module Slop
# This class encapsulates a Parser and Option pair. The idea is that
# the Option class shouldn't have to deal with what happens when options
# are parsed, and the Parser shouldn't have to deal with the state of
# options once parsing is complete. This keeps the API really simple; A
# Parser parses, Options handles options, and this class handles the
# result of those actions. This class contains the important most used
# methods.
class Result
attr_reader :parser, :options
def initialize(parser)
@parser = parser
@options = parser.options
end
# Returns an options value, nil if the option does not exist.
def [](flag)
(o = option(flag)) && o.value
end
# Returns an Option if it exists. Ignores any prefixed hyphens.
def option(flag)
cleaned = -> (f) { f.to_s.sub(/\A--?/, '') }
options.find do |o|
o.flags.any? { |f| cleaned.(f) == cleaned.(flag) }
