Subject: [ruby-core:19313] [Bug #642] __DIR__

Bug #642: __DIR__
http://redmine.ruby-lang.org/issues/show/642

Author: Thomas Sawyer
Status: Open, Priority: Normal

There is an snippet of code found in many Ruby scripts, especially testing scripts. It is...

  File.dirname(__FILE__)

For something so common --and something that can not, by its very nature, be put into a reusable method, it is annoying to have to repeatedly calculate the current scripts location. So I respectfully request that a future version of Ruby provide a built-in reference that can used instead:

  __DIR__

This will improve readability, remove the need for extra variables to store this information, and at the very least, save us many a keystroke.
