The computer running the bot will also have to be open to the web - it can't be behind a firewall. <br /> <br />First, add this code to your MediaWiki LocalSettings.php, replacing the IP address with the IP of the server/computer running the bot, and the port to whatever you want to use (probably something above 40,000, but it's up to you): <br /><code> <br />$wgRC2UDPAddress = '69.178.6.244'; <br />$wgRC2UDPPort = '41895'; <br />$wgRC2UDPPrefix = ""; <br /></code> <br /> <br />Now, you can run the bot! This is extremely hackish, because the retarded collective-mailing-list-coding system of the MediaWiki repos has somehow managed to code IRC color codes directly into their exported strings (at least with MediaWiki 1.2alpha, which is what I'm running right now). <br />You'll need to replace the new tinder definition with your subdomain on Campfire, the username and password with ones for the bot account you've created on your campfire room, and the room name with the room you want the updates to be sent to. <br /><code> <br />require 'rubygems' <br />require 'tinder' <br />require 'socket' <br />puts 'Dependencies loaded...' <br /> <br />campfire = Tinder::Campfire.new 'subdomain' <br />campfire.login 'email@domain.com', 'password' <br />exit unless room = campfire.find_room_by_name('Case Sensitive Room Name') <br />puts 'Campfire logged in...' <br /> <br />server = UDPSocket.new <br />exit unless server.bind('0.0.0.0', 41895) <br />puts 'Socket listening...' <br /> <br />loop do <br /> msg = server.recv(2048).gsub(/\003[\d]{0,2}/,'').chomp <br /> print "sending to room: #{msg.inspect}..." <br /> exit unless room.speak msg.to_s <br /> puts ' sent!' <br />end <br /></code> Sat, 26 Jan 2008 14:29:08 GMT http://snippets.dzone.com/posts/show/5037 elliottcable (elliott cable) http://snippets.dzone.com/posts/show/4793 Assuming you have Rails installed as a gem, the following Unix shell script (which I named String, but you can name anything you want when you save the following into a file) allows you to call Ruby String methods (including, importantly, the methods that the Rails ActiveSupport extensions add) on an arbitrary number of arguments, and it will print out the results, e.g., <br /> <br />$ String camelize snake_case_example another_snake_case_example <br /> <br />The output is: <br /> <br />SnakeCaseExample <br />AnotherSnakeCaseExample <br /> <br /><code> <br />#!/usr/bin/env ruby <br /> <br />if ARGV.size > 1 then <br /> gem 'activesupport' <br /> require 'active_support/core_ext/string/inflections' <br /> <br /> class String <br /> include ActiveSupport::CoreExtensions::String::Inflections <br /> end <br /> <br /> command = ARGV.shift <br /> ARGV.each { |argument| <br /> puts argument.send( command ) <br /> } <br />else <br /> # Print usage information <br /> puts "Usage: #{File.basename( __FILE__ )} <command> <argument_1> [<argument_2> ...]" <br />end <br /></code> Sun, 18 Nov 2007 04:49:21 GMT http://snippets.dzone.com/posts/show/4793 HotFusionMan (Al Chou) http://snippets.dzone.com/posts/show/4674 Hace Script / Ago Script <br />if we call with a timestamp of a month ago, he print "Hace 1 mes".
