A simple Campfire notifier for CruiseControl.rb

Here’s a simple builder plugin that you can use to make CruiseControl.rb post to Campfire when it starts a new build (showing the build messages), and when the build finishes.

I’ve stripped this down to be as simple as possible.

require 'rubygems'
require 'tinder'

class CampfireNotifier
  attr_accessor :subdomain, :username, :password, :room_name

  def initialize(project = nil)
  end

  def room
    @campfire ||= Tinder::Campfire.new(subdomain, :ssl => false) # SSL's not working as of tinder 0.17 on 2008-01-28
    @campfire.login(username, password) unless @campfire.logged_in?
    @room ||= @campfire.find_room_by_name(room_name)
  end

  def speak(message, options = {})
    room.join(true) # we get booted off after a while :/
    room.speak(message, options)
  rescue Exception => e
    CruiseControl::Log.error("Couldn't say '#{message}' in '#{room_name}': '#{e.message}'")
    @campfire = @room = nil
  end

  def new_revisions_detected(new_revisions)
    speak new_revisions.to_s, :paste => true
  end

  def build_finished(build)
    if build.failed?
      speak("Build #{build.label} of #{build.project.name} failed; see #{build.url}")
    else
      speak("Build #{build.label} of #{build.project.name} succeeded")
    end
  end
end

Project.plugin(CampfireNotifier)

Put this in lib/builder_plugins (or on older versions of CruiseControl.rb, in builder_plugins/installed).
