Little script to help me catch up on my mashups!

mashup_getter.rb

#!ruby

require 'rubygems'
require 'hpricot'
require 'open-uri'
require 'fileutils'

prefix = Time.new.strftime("%F")

FileUtils.mkdir(prefix) unless File.exists?(prefix)

pages = (2..14).to_a

pages.each do |page|

  doc = open("http://mashuptown.com/page/#{page}/")
  as = Hpricot(doc)/'a'

  mp3s = as.map{|x| x.attributes['href'] if x.attributes['href'].match(/\.mp3/)}.compact.uniq

  mp3s.each{|x|
    file = File.join(prefix, x.split('/').last)
  
    unless File.exists?(file)
      writeOut = open(file, "wb")
      writeOut.write(open(x).read)
      writeOut.close
      puts "downloaded  #{x}"
    end
  }

end
