A chat bot using Blather

[Saket Choudhary]

I am new to Ruby and Blather, I wanted to make a chatbot  which when pinged by a certain set of users will carry out some actions like "eamiling", "searching Google" etc.

I went forward like this :

created an array of allowed users :

allowed_users=["a...@ex.com","aa@bb,com"]

message :chat?,:body do |m|

   if allowed_users.include(m.from.to_s.split("/")[0])

        say m.from "Welcome User. Enter your choice : 1>Mail 2> Google"

       message :chat?,:body => 2 do |t|

         ?????

      end

   else

        say m.from "You aren't allowed here !"

end

As youi would have realised this doesn't work ! How do I maintain a "session" for a user and do the process accordingly>

For example if I am user a...@ex.com and now I want to Google for "Ruby:"

I ping  !

I get a "Welcome" reply!

I enter  "2"

but then how do I actually Google for Ruby ?

The problem is not about making the HttpRequest to Google.! How do I personalise my code for a particular user who has pinged  ?

Hey Saket,

Nesting the message handlers in the way you're doing now will cause some issues. You'll create a new handler every time someone sends a message. So the first thing would be to break that inner handler out.

The other thing I'd suggest would be to use JIDs instead of strings. If you make your list of allowed users a list of JIDs you wouldn't have to do the string manipulation yourself.

The way you're designing the system though, you'll need to keep track of the user's state, where they are in the menu system. It might be easier to have a user be explicit each time. Instead of "2" then "something I want to google" they'd write "google: something I want to google"

Below is how you might better break up your current script:

allowed_users = ["a...@ex.com", "a...@bb.com"].map { |j| Blather::JID.new(j) }

# this will guard all message handlers, checking to see that the user is valid

before(:message) do |m|

  if !allowed_user.include?(m.from.stripped)

    say m.from, "You aren't allowed here"

  end

  true

end

message :chat?, :body => '1' do |m|

  # mail

end

message :chat?, :body => '2' do |m|

  # google

end

message :chat?, :body do |m|

  say m.from, "Welcome ..."

end

Just one more query:

How do I set the status for the online bot?

status = Status.new

status.message = "Now Live"

This Didnt work !

[Ben Langfeld]

You will have to send the stanza, something like this:

write_to_stream Status.new(:available, "Now Live")

Regards,
Ben Langfeld

[Saket Choudhary]

This has to be protected by guards?

setup ENV['JID'], ENV['JPASSWORD']

write_to_stream Status.new(:available, "Now Live")

Didn't work.!

[Ben Langfeld]

You will have to do it in a when_ready block:

setup .....

when_ready do

write_to_stream Status.new(:available, "Now Live")

end

Ben Langfeld
