Subject: Re: How many single Methods provides Ruby ?

well here are two versions. using different methods, they both work. i don't 
know which is more accurate. but the second divides the job in two: Classes 
and Modules. anyone have a script that actually builds the hieararchy and 
thereby can get this exact?

anyway, i think your looking at around 1000 methods. whew, thats a lot!


VERSION 1:

mt = 0; cm = 0; im = 0;
Module.constants.each { |c|
    cnst = eval "#{c}"
    if cnst.respond_to?(:singleton_methods)
      cnst.singleton_methods.each { |m| puts m; cm +=1; mt +=1 }
    end
    if cnst.respond_to?(:public_instance_methods)
      cnst.public_instance_methods(false).each { |m| puts m; im +=1; mt +=1 }
    end
  }
  puts
  puts "Total Public Class Methods: #{cm}"
  puts "Total Public Instance Methods: #{im}"
  puts "Total Public Methods: #{mt}"


VERSION 2:

mt = 0; cm = 0; im = 0;
ObjectSpace.each_object(Class) { |cnst|
    puts "\n\n#{cnst}\n===============================\n"
    cnst.singleton_methods.each { |m| print "#{m}  "; cm +=1; mt +=1 }
    cnst.public_instance_methods(false).each { |m|
        print "#{m}  "; im +=1; mt +=1
     }
  }
  puts
  puts "Total Class Public Class Methods: #{cm}"
  puts "Total Class Public Instance Methods: #{im}"
  puts "Total Class Public Methods: #{mt}"

mt2 = 0; cm2 = 0; im2 = 0;
ObjectSpace.each_object(Module) { |cnst|
    puts "\n\n#{cnst}\n===============================\n"
    cnst.singleton_methods.each { |m| print "#{m}  "; cm2 +=1; mt2 +=1 }
    cnst.public_instance_methods(false).each { |m|
       print "#{m}  "; im2 +=1; mt2 +=1
     }
  }
  puts
  puts "Total Module Public Class Methods: #{cm2}"
  puts "Total Module Public Instance Methods: #{im2}"
  puts "Total Module Public Methods: #{mt2}"
