Proxen

Easy method_missing proxies.

Usage

It's sort of like ActiveSupport's Module#delegate, only for proxying.

class Something
  proxy_to :other_thing

  def other_thing
    OtherThing.new # or whatever
  end
end

Conditional Proxying via :if (or :unless)

You can pass a regex, so only matching methods will be proxied:

class Something
  proxy_to :other_thing, :if => /^[^_]/

  def other_thing
    OtherThing.new
  end
end

Something.new.hello # Will be proxied
Something.new._hello # Won't be proxied

How 'bout a symbol instead:

class Something
  proxy_to :other_thing, :if => :should?

  def should?(sym)
    PROXY_METHODS.include?(sym)
  end

  def other_thing
    OtherThing.new
  end
end

You can also use a Proc:

class Something
  proxy_to :other_thing, :if => proc { |sym| sym == :yes }

  def other_thing
    OtherThing.new
  end
end

Blank Slate Proxies

You can also make the class a blank slate, meaning everything will be proxied:

class Something
  proxy_to :other_thing, :blank_slate => true

  def other_thing
    OtherThing.new
  end
end

Something.new.inspect # Proxied to other_thing

Multiple Proxy Targets

To specify multiple proxy targets, just pass them all:

class Something
  proxy_to :other_thing, :something_else

  def other_thing
    # Whatever
  end

  def something_else
    # And again
  end
end

That's all for now.
