Simple Ruby script

Here is a very simple Ruby script to get you subscribing to messages, they simply get output to the console.

Note that you'll need environment variables set up with DATAFEEDS_USER as your username and DATAFEEDS_PASSWORD as your password - for the datafeeds.networkrail.co.uk site.


require 'stomp'

begin
 # Credentials set here as environment variables
 @user = ENV["DATAFEEDS_USER"];
 @password = ENV["DATAFEEDS_PASSWORD"]
 @host = "datafeeds.networkrail.co.uk"
 @port = 61618

 # Example destination add yours here
 @destination = "/topic/TD_ALL_SIG_AREA"

 puts "Connecting to datafeeds as #{@user} using stomp protocol stomp://#{@host}:#{@port}\n"
 @connection = Stomp::Connection.open @user, @password, @host, @port, true
 @connection.subscribe @destination

 while true
   @msg = @connection.receive
   puts @msg
 end
 @connection.disconnect
rescue
end
