Subject: Re: require does not work

Hi, Tony

Please see the FAQ of Ruby 1.9.2:
http://www.ruby-lang.org/en/news/2010/08/18/ruby-1-9.2-released/#label-7
It says:

The global variable $: (equivalent to $LOAD_PATH) is the list of load
path, which is used by the require method.
If you want to load your own ruby module which exists in the directory
/path/to/moddir, you need to append the path to $LOAD_PATH before
using the require method.

#stack.rb

# append the path into the load path list
$LOAD_PATH << "/path/to/moddir"

require "stacklike"

class Stack
  include Stacklike
end

s = Stack.new

Another way to append a path into $LOAD_PATH is to use a command line
option "-I".

$ ruby -I /path/to/moddir stack.rb
