There are a number of chatbots in Ruby out there but after I looked at
them I ended up creating my own.

You program it like this

miho.learn "whats|what_is the time?", "what time is it?", "time" do
  say_time()
end

Where say_time() returns a string which is displayed to the user

[AIML]$ rvm 1.8.7
[AIML]$ ./shell.rb
[Miho] Hello, how are you?
[You] what is the time
[Miho] It is nineteen fourteen
[You] what day is it
[Miho] Today is Sunday
[You] whats your ip address
[Miho] Sorry I didn't understand 'whats your ip address'
[You] what is your address
[Miho] My ip address is 192.168.1.2
[You] bye
[Miho] Bye. Come again
[AIML]$

It's pure ruby. I was in the process of converting the AIML ruleset
over but I was less than impressed with the rulesets (they didn't
really have much of interest in them) so I gave up on that. Presently
I have become sidetracked trying to integrate speech input and output
so the full Ruby shell has ground to a halt. I do however have mruby
embeded in a C based program that allows mruby to use espeak to to
speek the results.

I am in the process of getting Pocket Sphinx STT (speech to text) to
integrate with the C shell so that the input no longer comes from the
keyboard. Finally a computer that I can talk to that is fully
programable in Ruby :)

Then to port it to the Raspberry PI and away we go, it presently just
runs on Ubuntu with much cajoling.

If you want the Ruby only version I can zip it up for you, though you
will probably look at it and go "Is that all?" but it might be a
useful starting point.
