There is no need for control structures anyway:

-------------------------------------------------------------
def Dir.listing path
  prefix = {'directory' => '[dir] ', 'file' => '      '}
  glob("#{path}/*").map{|file| prefix[File.ftype file] + file}
end
puts Dir.listing('.')
-------------------------------------------------------------
