Simple MQTT-based chat room client written in Ruby

Install

1. Install and run an MQTT broker. mosquitto is one choice, this also works with RabbitMQ version 3 which includes MQTT support, and with many other MQTT servers.

2. Install the mqtt and ncurses-ruby gems (NB the plain ncurses gem is harder to natively compile)

   sudo gem install mqtt ncurses-ruby

Run

1. Run the client

   ruby ./mqtt-chat.rb <username>

2. If you want to configure the app to run against an alternative MQTT broker running on a different host/post. Modify this line:

   mqtt = MQTT::Client.new('localhost')

   replacing 'localhost' with the hostname or IP address of your chosen broker, optionally with a port number, e.g.

   mqtt = MQTT::Client.new('m2m.eclipse.org', 1883)
