Yet another mechanize snippet. I'm getting used to it. Gets the played songs count of $USER Requires: rubygems, mechanize

lastfm-played-songs-count

#!/bin/env ruby
# encoding: utf-8
# This is just a proof of concept, not for general usage.
require 'rubygems'
require 'mechanize'

last_fm_url = 'http://last.fm/user/'

user = ARGV[0]
a = Mechanize.new { |agent| 
	agent.user_agent_alias = 'Linux Firefox'
}

if(ARGV.length < 1)
	puts "feed me a user within the first agument"
	Process.exit
end

begin
	page = a.get(last_fm_url + user)
	numbers = page.parser.xpath("//*[@class='flip']").inner_html

  	if(numbers.length < 1) 
		puts "User not existing, or didn't listen to any songs"
		Process.exit
	end

	puts numbers

rescue Mechanize::ResponseCodeError => ex
	case ex.response_code
	when '404' then
 	puts 'User not found'
	else
	puts 'Error:' + ex.message
	end
	Process.exit
end
