A script to download all Peepcode screencasts with ruby & wget (supports resume)

peepcode.rb

require 'mechanize'

@username      = 'user@domain.com'
@password      = 'hi2u'
@download_path = File.expand_path 'downloads'
@wget_cookie   = File.expand_path(File.dirname(__FILE__)) + '/wget-cookies.txt'

unless File.directory? @download_path
  puts "@{download_path} doesn't exist!"
  exit
end

agent = Mechanize.new
agent.cookie_jar.load('cookies.yml') if File.exists?('cookies.yml')

page = agent.get 'https://peepcode.com/'

unless page.body.match /\/peepers\/account\/edit/
  puts "Logging in"
  page = agent.get 'https://peepcode.com/login'

  signin_form          = page.form_with(:action => '/sessions')
  signin_form.email    = @username
  signin_form.password = @password

  agent.submit(signin_form, signin_form.buttons.first)
  agent.cookie_jar.save_as('cookies.yml')
end

def wget(path)
  unless File.exists?('wget-cookies.txt')
    cmd = "wget --no-check-certificate  --keep-session-cookies --save-cookies wget-cookies.txt "
    cmd<< "--post-data 'email=#{@username}&password=#{@password}' https://peepcode.com/sessions"
    system cmd
  end

  system "cd #{@download_path}; wget --load-cookies #{@wget_cookie} --continue '#{path}'"
end

page = agent.get 'https://peepcode.com/products'

page.links_with(:href => %r{/products/}).each do |link|
  puts "Processing #{link.text}"
  result = agent.click link
  links = []
  download_links = result.links_with(:href => %r{/unlimited_downloads/}).each do |dl|
    ogg = dl.href.match(/\.ogg/)
    s3  = (dl.text.match(/USA-West/) || dl.href.match(/s3=true/))
    wmv = dl.href.match(/wmv_zip/)

    if !s3 && !ogg && !links.include?(dl.href) && !wmv
      links.push dl.href
      wget dl.href
    end
  end
  puts
end

does download path need to be absolute?

Found issue... doesn't handle spaces in download path.
