Introducing the Sps_chat gem

The following example shows how to set up a simple chat session between 2 users.

Gem install the following:

• simplepubsub
• sps_chat

Open an IRB session and paste in the following:

require 'simplepubsub'

SimplePubSub::Broker.start(port: 8080)

1. Open another IRB session and paste in the following:

   require 'sps_chat'

   chat = SPSChat.new port: 8080

2. Open another IRB session and paste the above code into it

3. Type the following in IRB session 1:

   chat.send 'hello'

4. Now type the following in IRB session 2:

   chat.send 'hi!'

5. Observe the message sent from IRB session 1 appeared in session 2, and the message from IRB session 2 appeared in session 1.

Notes:

• If no userid is given, one is created. To specify a userid, pass it into the intialize method e.g. SPSChat.new port: 8080, userid: Cedrik
• The topic is set to chat followed by the userid (e.g. chat/user777)
