uri_part_of(uri, part) click to toggle source

Returns true if the given 2 URIs have a part_of relationship.

the same scheme
the same host String (no host resolution or IP-addr conversion)

keyword_argument(args, *field) click to toggle source

Keyword argument helper.

args	given arguments.
*field	a list of arguments to be extracted.

You can extract 3 arguments (a, b, c) with:

  include Util
  def my_method(*args)
    a, b, c = keyword_argument(args, :a, :b, :c)
    ...
  end
  my_method(1, 2, 3)
  my_method(:b => 2, :a = 1)

instead of;

  def my_method(a, b, c)
    ...
  end

    # File lib/httpclient/util.rb, line 37
37:     def keyword_argument(args, *field)
38:       if args.size == 1 and args[0].is_a?(Hash)
39:         args[0].values_at(*field)
40:       else
41:         args
42:       end
43:     end

urify(uri) click to toggle source

Gets an URI instance.

    # File lib/httpclient/util.rb, line 46
46:     def urify(uri)
47:       if uri.nil?
48:         nil
49:       elsif uri.is_a?(URI)
50:         uri
51:       else
52:         URI.parse(uri.to_s)
53:       end
54:     end
