Random wallpaper from socwall.com

I quite like http://socwall.com. They have a rss feed for recent posts, but I wrote a small script to download a random selection instead.

On OSX I could then set my desktop background to be a random picture from a folder. In my case that folder was /Users/brad/Pictures/Wallpapers/ but that could be easily changed.

The code is after the jump.

#!/usr/bin/ruby

require 'rubygems'
require 'hpricot'
require 'open-uri'
require 'Pathname'
 
URL = 'http://socwall.com/browse/index.php?wpSortby=8'
DEST = "/Users/brad/Pictures/Wallpapers/"


def clear_old_images
  Pathname.new(DEST).children.each { |f| f.delete }
end

def download_images(count)
  count = count.to_i
  
  while count > 0
    doc = Hpricot(open(URL))
    
    doc.search("div.wpThumbnail").each do |thumb|
      next if count == 0
      
      thumbnail = thumb.at("img")['src']
      image = thumbnail.gsub(/\/tb_/, '/')
      image = image.gsub(" ", "%20")
      
      remote_image = open(image, "User-Agent" => "Ruby/#{RUBY_VERSION}")
      local_image = open("#{ DEST }/#{ count }.png", 'w')
      local_image.write(remote_image.read)
      
      remote_image.close
      local_image.close
      
      count -= 1
    end
  end
end

count = ARGV[0] || 10

clear_old_images
download_images(count)
