A proxy through Roxy

Roxy is a pretty sweet library. It allows you to easily define and use proxies for any Ruby class.

Although, I do have one minor gripe. I think yielding the proxy_owner and proxy_target variables to the block (rather than them just being automatically available) would be better. It’d leave more room for readability, in my opinion.

For example, instead of:

1
2
3
4
5
6
7
8
9
10
11
12
13

class Person
  include Roxy::Moxie

  attr_accessor :parents

  proxy :parents do
    def divorced?
      # the 'proxy_owner' variable refers to the person 
      # instance and the 'proxy_target' variable refers 
      # to the parents
    end
  end
end

You’d be able to do:

1
2
3
4
5
6
7
8
9
10
11
12
13

class Person
  include Roxy::Moxie

  attr_accessor :parents

  proxy :parents do |person, parents|
    def divorced?
      # now it becomes immediately obvious that the
      # 'person' variable refers to the person instance,
      # and the 'parents' variable refers to the parents
    end
  end
end

I know, I know. “Just fork it and make the change, stupid”. And you’re absolutely right. Unfortunately, I just don’t have an immediate need for this or I might.

I can’t wait until I do need this, though. What a great way to make good code even better.

And here’s the repo on github if you didn’t already pick up on that.
