require 'net/http'
require 'uri'
require 'rubygems'
require 'curb'


JoomlaSession = Struct.new(:key, :value)

class JoomlaModuleInstaller
  attr_accessor :file_path, :url, :login, :password
  def initialize(login, password, file_path = "", url = "")
    @login = login
    @password = password
    @file_path = file_path
    @url = URI.parse(url)
  end

  def install
    raise "Get session failed" unless joomla_session
    raise "Login Failed" unless login
    raise "Upload token not found" unless upload_form_token
    install_module
    successful?
  end

  def message
    @message.gsub!(/<\/?\w{1,4}( class="[\w\s]*")?>/, '').gsub!(/\n\t/im, "  ")
  end

  def failed?
    @failed
  end

  def successful?
    !failed?

Example :

@file = "com_acajoom.zip"
@url = 'http://www.example.com/jos/administrator/index.php'
@login = "admin"
@password = "password"

installer = JoomlaModuleInstaller.new(@login, @password, @file, @url)
if installer.install
  puts "#{@file}: Module installation succeeded"
else
  puts installer.message
