Why is Ruby's Date class automatically loaded but DateTime is not?
ruby
Solution
Being a little more curious, I tried:
$ ruby -e 'puts DateTime.class'
-e:1:in `<main>': uninitialized constant Object::DateTime (NameError)
[~, kamilski81@mac]
$ ruby -e 'puts Date.class'
-e:1:in `<main>': uninitialized constant Object::Date (NameError)
$ ruby -e 'puts Time.class'
Class
So it makes me think that it's an irb issue that automatically loads 'date'.
Problem
Using IRB, why are the Date & Time classes automatically loaded, but DateTime is not? I have to `require 'date'`, this does not make sense to me because I thought that both Date and DateTime were using the standard library `'date'`? ``` ruby-1.9.2-p290 :001 > Date => Date ruby-1.9.2-p290 :002 > Time => Time ruby-1.9.2-p290 :003 > DateTime NameError: uninitialized constant Object::DateTime from (irb):3 from /Users/kamilski81/.rvm/rubies/ruby-1.9.2-p290/bin/irb:16:in `<main>' ruby-1.9.2-p290 :004 > require 'date' => true ruby-1.9.2-p290 :005 > require 'date' => false ruby-1.9.2-p290 :006 > DateTime => DateTime ```
