Readme.md

Get the most recommended games from steam (because steam does not tell...) this is an example and no invitation to DDos steam ;)

finder.rb

id = ARGV[0].to_i # starting id is first argument
MAX = 50 # max requests
MAX_FAILS = 20 # abort after 20 failures -- at end of catalog ?
SEARCH = /([\d+,]+) players recommend this game to their friends/
TITLE = %r{<title>(.*?)</title>} # title of the app

max = id + (MAX * 10)
fails = 0
results = []

def url(id)
  "http://store.steampowered.com/app/#{id}"
end

def pretty(count,id,title)
  "#{count} : #{title} : #{url(id)}"
end

loop do
  page = `curl '#{url(id)}' 2> /dev/null`

  if page =~ SEARCH
    count = $1.sub(',','').to_i
    title = (page.match(TITLE)[1] || '???').sub(' on Steam','')
    result = [count, id, title]
    puts "Found #{pretty(*result)}"
    results << result
    fails = 0
