Downloads the latest MP3 from XLR8R

xlr8r.rb

#!/usr/bin/env ruby

# Dependencies: wget and the following gems:
require 'rubygems'
require 'feedzirra'
require 'httparty'

feed_url = 'http://feeds.xlr8r.com/xlr8rmp3s'
feed = Feedzirra::Feed.fetch_and_parse(feed_url)

mp3s = {}

print 'Parsing feed'
feed.entries.each do |entry|
  response = HTTParty.get(entry.url)
  if response.code == 200
    response.body =~ /http:.*\.mp3/i
    mp3s[$&] = entry.title
    print '.'
  end
end

print "\n"

mp3s.each do |url, title|
  title = title.sub(/ "/, ' - ').sub(/"$/, '')
  puts "Downloading [#{title}] from [#{url}]\n"
  `wget -c "#{url}" -O "#{title}.mp3"`
end

=begin

  BONUS: if you don't want/can't use wget, substitute the wget line with this block:

  mp3 = HTTParty.get(url)
  if mp3.code == 200
    open("#{title}.mp3", 'wb') do |file|
      file.write(mp3.body)
    end
  end
