The DSL Namespaced

You can opt out of the default behavior of mixing the DSL methods into Kernel by including the DSL itself and mixing them into your own namespace. This enables the ability to run multiple clients within the same process.

Using this method you’ll lose the command line options. Setup, start, and daemonization will need to be handled within the script.

The following example is a single ruby process that plays ping-pong with itself over XMPP:

require 'blather/client/dsl'
$stdout.sync = true

module Ping
  extend Blather::DSL
  def self.run; client.run; end

  setup '[email protected]/ping', 'echo'

  status :from => Blather::JID.new('[email protected]/pong') do |s|
    puts "serve!"
    say s.from, 'ping'
  end

  message :chat?, :body => 'pong' do |m|
    puts "ping!"
    say m.from, 'ping'
  end
end

module Pong
  extend Blather::DSL
  def self.run; client.run; end

  setup '[email protected]/pong', 'echo'
  message :chat?, :body => 'ping' do |m|
    puts "pong!"
    say m.from, 'pong'
  end
end

trap(:INT) { EM.stop }
trap(:TERM) { EM.stop }
EM.run do
  Ping.run
  Pong.run
end
