Still I get the error.

ruby -v

ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

irb(main):001:0> require "date"

irb(main):002:0> Date::MONTHNAMES

DATE::ABBR_MONTHS exists in this doc here.
http://www.ruby-doc.org/stdlib/libdoc/date/rdoc/index.html

And I was using this functionality till ruby 1.8.2 it suddenly stoped
with the upgrade. can these guys just remove stuff without warning!!! or
am I looking at wrong place?

Please help

Hi Gosar,

In your irb example you have DATE::ABBR_MONTHS instead of Date::ABBR_MONTHS. In this case Ruby interprets DATE as a constant instead of a class, therefore you get an error. Here's my output:

irb(main):001:0> require 'date'
=> true
irb(main):002:0> Date::ABBR_MONTHS
=> {"oct"=>10, "jul"=>7, "jan"=>1, "dec"=>12, "jun"=>6, "apr"=>4, "feb"=>2, "may"=>5, "sep"=>9, "aug"=>8, "mar"=>3, "nov"=>11}
irb(main):003:0> DATE::ABBR_MONTHS
NameError: uninitialized constant DATE
         from (irb):3

HTH.

Chris
