Question

I hope I am not repeating anyone here, but I have been searching google and here and not coming up with anything. This question is really more a matter of “sexifying” my code.

What I am specifically trying to do is this:

Dir.new('some_directory').each do |file|
  # is there a way to refer to the string 'some_directory' via a method or variable?
end

Thanks!

Not in general; it’s totally up to the method itself what arguments the block gets called with, and by the time each has been called (which calls your block), the fact that the string 'some_directory' was passed to Dir.new has been long forgotten, i.e. they’re quite separate things.

You can do something like this, though:

Dir.new(my_dir = 'some_directory').each do |file|
    puts "#{my_dir} contains #{file}"
end
