problems subclassing ip

[Canx]

Hi,

thanks for sharing this great library!

I'm trying to inherit from IP but I've got problems with the constructor:

$ ruby ip_extended.rb 
/var/lib/gems/2.3.0/gems/ruby-ip-0.9.3/lib/ip/base.rb:22:in `new': wrong number of arguments (given 3, expected 1) (ArgumentError)
        from ip_extended.rb:9:in `<main>'

The code:

require 'ip'

class IPExtended < IP
  def initialize(ip, param2, param3)
    super(ip)
  end
end

ip = IPExtended.new("192.168.1.1", true, true)
puts ip.to_s

I don't know what I'm doing wrong, could you help me please?

You'll have to be careful trying to do this. "IP.new" is overridden, so that it actually creates and returns an instance of IP::V4 or IP::V6 depending on the arguments given. It wasn't really designed to be extended the way you're trying.

Ok, I understand...

finally I used method_missing to extend the class:

require 'ip'

class IPExtended
  def initialize(ip, param2, param3)
    @ip = IP.new(ip)
    @param2 = param2
    @param3 = param3
  end

  # extended methods...

  def method_missing(method, *args, &block)
    @ip.send(method, *args, &block)
  end

end

ip = IPExtended.new("192.168.1.1", true, true)
puts ip.to_s
