module Abbrev
  # Given a set of strings, calculate the set of unambiguous abbreviations for
  # those strings, and return a hash where the keys are all the possible
  # abbreviations and the values are the full strings.
  #
  # Thus, given `words` is "car" and "cone", the keys pointing to "car" would be
  # "ca" and "car", while those pointing to "cone" would be "co", "con", and
  # "cone".
  #
  #     require 'abbrev'
  #
  #     Abbrev.abbrev(%w{ car cone })
  #     #=> {"ca"=>"car", "con"=>"cone", "co"=>"cone", "car"=>"car", "cone"=>"cone"}
  #
  # The optional `pattern` parameter is a pattern or a string. Only input strings
  # that match the pattern or start with the string are included in the output
  # hash.
  #
  #     Abbrev.abbrev(%w{car box cone crab}, /b/)
  #     #=> {"box"=>"box", "bo"=>"box", "b"=>"box", "crab" => "crab"}
  #
  #     Abbrev.abbrev(%w{car box cone}, 'ca')
  #     #=> {"car"=>"car", "ca"=>"car"}
