list attr_accessors

list_attr_accessor

# there may be a better way that is not ghetto, 
# however I will show you how to list attr_accessors, 
# actually have them returned as strings in an array:

class Awesome
  attr_accessor :beer, :chips, :mullet
  def initialize
    @awesome = "dude"
  end
end

rad = Awesome.new

def list_attr_accessor(obj)
  (obj.methods - Object.methods).map {|x| x.chomp("=") if x =~ /=$/}.compact
end

list_attr_accessor(rad) # => ["beer", "chips", "mullet"]
