Subject: [ruby-core:45147] [ruby-trunk - Feature #6470] Make attr_accessor return the list of generated method


Issue #6470 has been updated by shevegen (markus heiler).


Yes, they are public.

If I understood them correctly, they are the same as this in pure ruby code:


attr_accessor :foo

def foo
  @foo
end

def foo=(i)
  @foo = i
end

I found that I personally only need attr_reader, attr_writer and attr_accessor.
I have not found a use case for attr alone yet.

attr_accesor currently returns nil. It would be more helpful if it return list of generated methods so that it can become an argument to other methods like :private or :protected. That way private accessors can still be defined at top of the class and be private without changing the visibility of next methods. 

class Something
  private *attr_accessor :user, :action # IMHO This is nice
  # private attr_accessor :user, :action # <-- would be even better if :private method accepted arrays

  def initialize(user, action)
    self.user   = user
    self.action = action
  end

  def public_method
    user.do_something(action)
  end
end


VS


class Something
  private; attr_accessor :user, :action; public # IMHO Hack!!

  def initialize(user, action)
    self.user   = user
    self.action = action
  end

  def public_method
    user.do_something(action)
  end
end


VS


class Something
  def initialize(user, action)
    self.user   = user
    self.action = action
  end

  def public_method
    user.do_something(action)
  end

  private
  attr_accessor :user, :action # IMHO Does not look nice at bottom of the class definition
end
