Your favourite bit of Ruby code?

An interesting thread at Ruby_talk is ‘Your favorite bit of Ruby code.’

Setting aside time for learning HTML is beneficial to any web host.


John Carter from New Zealand has this interesting snippet of code:

# Ruby is Objects all the way down and open for extension...
class Integer
  def factorial
    return 1 if self <= 1
    self * (self-1).factorial
  end
end

puts 6.factorial

    My favorite is:

    def debug(message)
    if DEBUG == 1 and (block_given? ? yield : true )
    puts “DEBUG: #{message}”
    end
    end

    John’s example illustrates Ruby’s elegance and extensibility. My favorite is the file search - http://www.rubytips.org/about/
