Subject: Re: Intra-module method calls

I just want to have some utility methods for use by my app.
The code below works.
Notice the calls to add_default_path in the other two methods.

My question is: why do I have to qualify the name of add_default_path 
with ESimplyUtil since no external code is calling that method?  Why 
can't I just have

def add_default_path
end

?

Thanks,
WG

===================

Here's my module:

module ESimplyUtil
  public
  def ESimplyUtil.validate_and_format_url(in_url)
    begin
      url = URI.parse(in_url)
    rescue
      raise("This is not a valid URL")
    end


    #If the URL is valid HTTP URL, default the path if necessary
    #If the URL is generic make it into an HTTP URL
    # Get the host - match the first set of non-/ characters
    # Get the path - match all of the characters including the first 
slash
    #If the URL is a valid non-HTTP URL, then it's an error.
    if (url.instance_of?(URI::HTTP))
      url = add_default_path(url)
    elsif (url.instance_of?(URI::Generic))
      if (((url.scheme != nil) && (url.scheme != "http")) ||
          (url.path.nil?) || (url.path == ''))
        raise("This is not a valid URL")
      else
        port = 80
        host = url.path.match(/[^\/]+/)[0]
        path_match = url.path.match(/\/(.*)/)
        if (path_match.nil?)
          path = '/'
        else
          path = path_match[0]
        end

        url = URI::HTTP.new('http', nil, host, 80, nil, path, nil, nil, 
nil)
      end
    elsif (! url.instance_of?(URI::HTTP))
      raise("This is not a valid URL")
    end

    url
  end

  public
  def ESimplyUtil.get_URL(myURL)
    url = URI.parse(myURL)
    url = add_default_path(url)
    req = Net::HTTP::Get.new(url.path)
    res = Net::HTTP.start(url.host, url.port) {|http|
      http.request(req)
    }

    res
  end

  private
  def ESimplyUtil.add_default_path(url)
  	if ((url.path == '') || (url.path.nil?))
      url.path = '/'
    end

    url
  end
end
