LA Ruby Meetup was very cool. So I was the first to be at the scene. I helped bring the food to the room since I was in the lobby and greeted by Jody. I meet and greeted all of the LA Times people. Also meet some guy from Yahoo!, sorry I forgot your name already, and one from heroku, BizQuest another from PGP, and another from Experian. As-well as more but I sorta forgot everyones name already… or at least I can’t remember them, yet.

If you’re in the Los Angeles Area check it out.
Yellowpages.com will be hosting LA Ruby Meetup #2 on July 17 2008, so mark that in your calendar. Join the Yahoo Group, LARuby

String.class_eval {
  define_method(:translate_to) do |lang|
    text = case lang
           when :spanish
           “Buenos Dias, Como estas hoy?“
           when :english
           “Good Morning, How are you today?“
           else
           “I don’t speak any other language.“
           end
  end
}

puts “Sentence“.translate_to :spanish
# => Prints out “Buenos Dias, Como estas hoy?”

puts “Sentence“.translate_to :english
# => Prints out “Good Morning, How are you today?”

puts “Setenece“.translate_to :portuguese
# => Prints out “I don’t speak any other language.”

puts “Sentence“
# => Prints out “Sentence”

So while messing round I made this in Ruby… I’m not sure if it is considered meta programming? Well, it’s just adding a method to the String class. I get confused when to consider things to be meta programming.. Maybe I over think about it.

So I received an invite for heroku a while ago. I never really used it. Want an invite to check out heroku.com? I have many invites to give away. Want one? just leave your email and I will send you one your way!

Dreamhost now supports mod_rails Passanger.

So even if you have never set-upped a Rails Application to Production server there is still hope for you. Introducing Passenger a mod_rails for Apache… Make it super simple to deploy apps just like PHP. Check it out over at modrails.com 

Meta Programming is code that writes code. See the code sample below.
I have made a screencast of this process. View it here

#!/usr/bin/env ruby

class Product
  def initialize(items)
    items.each {|item| Product.product(item) }
  end

  def self.product(item)
    code = %Q{
      def add_#{item}(item)
        @#{item} = [] unless @#{item}
        @#{item} << item
      end

      def display_#{item}s
        @#{item}.each {|item| puts item }
      end
    }
    class_eval(code)
  end
end

class Item < Product
  def initialize(*items)
    super(items)
  end
end

cart = Item.new(:book, :computer, :music)
cart.add_book(:Ruby) # => Add a book to our cart items

cart.display_books # => We want to display All books we have added
puts "\n"

cart.add_computer(:Apple)
cart.add_computer(:Dell)
cart.add_computer(:Sony)
cart.display_computers # => Display All Computers
puts "\n"

cart.add_music(’Modest Mouse‘)
cart.add_music(’Northstar‘)
cart.display_musics # => Display All Music Items

In Ruby a switch statement looks like this

say = "Hello"

case say
when "Hello" then
	puts "Say Hello"
when "Bye" then
	puts "Say Bye"
end

In PHP a switch statement looks like this

I have written a MySpace Status Updater class in Ruby. So if you want it take it, download it, use it.Download Here Or Download the RubyGem 

How do you use it?

credentials = {:username => ”, :password => ”, :status => %q(Okay Now I am really Done!…)}

@status = MySpace.update_status(credentials)
