class KeyboardHandler < EM::Connection

  include EM::Protocols::LineText2

 

  def post_init

    print "> "

  end

 

  def receive_line(line)

    line.chomp!

    line.gsub!(/^\s+/, '')

   

    case(line)

    when /^get (.*)$/ then

      site = $1.chomp

      sites = site.split(',')

     

      multi = EM::MultiRequest.new

      sites.each do |s|

        multi.add(EM::HttpRequest.new(s).get)

      end

      multi.callback {

        puts ""

        multi.responses[:succeeded].each do |h|

          pp h.response_header.status

          pp h.response_header

        end

        multi.responses[:failed].each do |h|

          puts "#{h.inspect} failed"

        end

I decided to try my hand at creating a screencast the other day. I took a look at the EventMachine EM-HTTP-Request library and created a simple shell program to do single and multi requests. Take a look and let me know what you think.
