on_message and on_private_message

I am currently using XMPP4R on Cloud9.

conference.on_message {|time, nick, text|
     case text
        when /regex/i
            #Same Command as on_private_message
        end
     end
}

conference.on_private_message {|time,nick, text|
     case text
        when /regex/i
            #Same Command as on_message
        end
     end
}

conference.on_message is the conference's message from a chat, and conference.on_private_message is the conference's private message chat.

I want to make both on_message and on_private_message to function as 1 instead of 2 shown above.

I tried something like this (below), but it worked only conference.on_private_message. How can I make it possible?

(conference.on_message || conference.on_private_message) { |time, nick, text|
    case text
        when /regex/i
            #Same Command on both on_message and on_private_message
        end
     end  
}

As I understand the purpose is to DRY your code. It might be worth creating a Proc object and sending it to both functions.

proc = Proc.new { |time, nick, text|
case text
    when /regex/i
        #Same Command on both on_message and on_private_message
    end
 end  
}
conference.on_message(&proc)
conference.on_private_message(&proc)

You could also try using #send method.

[:on_message, :on_private_message].each { |m| conference.send(m, &proc) }
