Subject: [ruby-core:28898] [Feature #1961] Kernel#__dir__

Issue #1961 has been updated by Roger Pack.


My personal preference would be __DIR__

Here's a example patch that seems to work, if it's helpful at all.

Index: prelude.rb
===================================================================
--- prelude.rb  (revision 27020)
+++ prelude.rb  (working copy)
@@ -22,3 +22,12 @@
     }
   end
 end
+
+# Kernel
+
+module Kernel
+  def __DIR__
+    filename = caller[0][/^(.*):/, 1]
+    File.expand_path(File.dirname(filename))
+  end
+end

(gleaned from an old Ramaze copy).

I'd be happy to add tests or change the name or what not, as well, if so directed.
Thanks.
