Something I just came up with on the spot (never used this
before):
(Pastied at http://pastie.caboo.se/7
9068 for better viewing)
## loader.rb
module Loader
def require_class(klass)
%w(instance class).each do |w|
require File.join(klass,w) if File.exist?
File.join(klass,w
+'.rb')
end
end
end
include Loader
## my_class/instance.rb
class MyClass
def inst_method
puts "I'm in the instance"
end
end
## my_class/class.rb
class << MyClass
def class_method
puts "I'm in the class"
end
end
## example code:
require_class 'my_class'
MyClass.class_method #=> "I'm in the
class"
MyClass.new.inst_method #=> "I'm in the
instance"
