Subject: Re: accessor methods for class methods


Thanks. That makes sense. I want to do what is simplest, but it seems 
without cattr things would get worse. Here is what I'm trying to do:

I have one rb file used for inputs:

require 'rubygems'
require 'activesupport'
  class Input
    cattr_reader :y
    def self.y
      @y = 2
    end
  end

**except I have lots of vars instead of just :y and I'm assigning them 
values here.

Then I go to a new rb file and do this:

require 'firstfile.rb'
class NewClass
  def do_something
    Input.y * 2.3
  end
end

new = NewClass.new
p new.do_something

**The fact that I need to say "Input.y" seems very bulky. Is there a 
better way to do this? Plus, if I get away from class vars, it will get 
bulkier. any ideas?
