= ProcForCaseEquality.new { puts 'procs in case statements are cool!' } == Features Simple yet powerful: it lets you use procs for case comparisons (see the example below). == How +case+ statements call the === method, so I wrote a +ProcForCaseEquality+ class that inherits from +Proc+ and overrides ===, letting the case statement call the proc passing the value of the case as argument. The source code is so simple that I can put it in full here: class ProcForCaseEquality < Proc def ===(*params) self.call *params end end 5 LOCs :P == Installation gem install proc_for_case_equality *COMING* == Usage / Examples require 'proc_for_case_equality' # OR: require 'proc_for_case_equality/pfce' # if you want PFCE constant to point to ProcForCaseEquality # Define some procs all_multiples_of_3 = ProcWithCaseEquality.new { |numbers| numbers.all? { |number| number.modulo(3).zero? } } any_multiple_of_3 = ProcWithCaseEquality.new { |numbers| numbers.any? { |number| number.modulo(3).zero? } } # Here we come case [1, 2, 3] when all_multiples_of_3 puts 'all numbers are multiples of 3' when any_multiple_of_3 puts 'at least one number is multiple of 3' else puts 'no multiples of 3' end == Inspired by {This article}[http://www.aimred.com/news/developers/2008/08/14/unlocking_the_power_of_case_equality_proc/] == License MIT (see {LICENSE}[https://github.com/ProGNOMmers/proc_for_case_equality/blob/master/LICENSE])
