Pretty Ruby Methods

pretty_methods.rb

#Pretty Methods
#you can call any_object.pretty_methods
#it will return a hash of classes from that objects ancestor chain, and all the method names (as symbols) of that object which are created by that ancestor.

#example: 5.pretty_methods: {Fixnum=>[:%, %+, :odd? ....], Integer=>[:ceil,:round,...],...Kernel=>[:is_a?, :taint, ...]
#you can pass the parameter 'false' to get back classes as strings, instead of Class objects


#add 'require <path>/pretty_methods.rb' to your .irbrc file, and have the fun by default!
