revisting a topic brought up a few times before. a good reference
being:


http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/74f323436b2bc85f/0c7780b698866cc5?lnk=gst&q=load+import&rnum=4&hl=en#0c7780b698866cc5

after considerable thought i think the interface that makes the most
sense is #module_load / #module_require. below is an implementation
please suggest improvements to the code.

thanks,
t.

module Module

  # Load file into module/class namespace.

  def module_load( path )
    if path =~ /^[\/~.]/
      file = File.expand_path(path)
    else
      $LOAD_PATH.each do |lp|
        file = File.join(lp,path)
        break if File.exist?(file)
        file = nil
      end
    end

    module_eval(File.read(file))
  end

  # Require file into module/class namespace.

  def module_require( path )
    if path =~ /^[\/~.]/
      file = File.expand_path(path)
    else
      $LOAD_PATH.each do |lp|
        file = File.join(lp,path)
        break if File.exist?(file)
        file += '.rb'
        break if File.exist?(file)
        file = nil
      end
    end

    @loaded ||= {}
    if @loaded.key?(file)
      false
    else
      @loaded[file] = true
      module_eval(File.read(file))
      true
    end
  end

end


class Class
  alias class_load module_load
  alias class_require module_require
end
