Ordina puzzle in Ruby

08 Dec 2007 19:14 - (0) comments

Ordina is running a campaign to attract Java developers.

Here is my version of the puzzle in Ruby. For a better comparison I've kept some of the Java style code and refrained from some one liners. Still, it's about half as long as the Java version.
My solution to the puzzle uses wikipedia to lookup the acronyms.

ordina.rb

require 'open-uri'

module Nl

  module Ordina

    class JavaSpecialist
	
      def self.main

        js = find_specialist_wanna_be

        if js

          js.start

        else

          puts "Geen JavaSpecialist implementatie gevonden"

        end

      end
	
      def start

        report = "Volgens de specialist #{name}\x5c\x6eHebben de volgende termen de betekenis" +

                  "\x5c\x6e\x55\x4d\x4c #{eval "waarStaat\x55\x4d\x4cVoor" } \x5c\x6e\x52\x55\x50 " +

                  "#{eval "waarStaat\x52\x55\x50Voor" } \x5c\x6e\x58\x4d\x4c #{eval "waarStaat\x58\x4d\x4cVoor" } " +

                  "\x5c\x6e\x4d\x56\x43 #{eval "waarStaat\x4d\x56\x43Voor" } \x5c\x6e\x45\x4a\x42 " +

                  "#{eval "waarStaat\x45\x4a\x42Voor" }\x5c\x6e\x41\x4f\x50 #{eval "waarStaat\x41\x4f\x50Voor" } " +

                  "\x5c\x6e\x4a\x53\x46 #{eval "waarStaat\x4a\x53\x46Voor" }"

        puts report.gsub!('\n', "\n")

        puts kijk_bij_ordina

      end      
	
      private
	
      def self.find_specialist_wanna_be

        dir = Nl::Ordina.name.gsub('::', '/').downcase

        Dir.new(dir).each{|i| require("#{dir}/#{i}") unless File.directory?("#{dir}/#{i}") }

        Nl::Ordina.constants.each do |i|

          unless i == self.name.split('::').last

            obj = instance_eval(i).new

            return obj if obj.is_a? JavaSpecialist

          end

        end

      end
	
      def kijk_bij_ordina

        open("http://jobportal.ordina.nl/jobportal-front/pages/index.jsf").read

      rescue

        'Kijk op http://jobportal.ordina.nl/'

      end

    end

  end

end

Nl::Ordina::JavaSpecialist.main

nl/ordina/impl.rb

module Nl

  module Ordina

    class JavaSpecialistImpl < JavaSpecialist

      def name

        "p8"

      end
	
      def method_missing(*args)

        afk = args.first.to_s.gsub('waarStaat', '').gsub('Voor', '')

        page = open("http://en.wikipedia.org/wiki/#{afk}").read

        matchdata = /<title>([^>]*)(<\/title>)/.match(page)

        matchdata ? matchdata[1].gsub('- Wikipedia, the free encyclopedia', '') : 'Onbekend'

      end

    end

  end
