Simple OS Chatbot

[Frank]

Want to make your own chatbot? Void already posted chatbot code, so I assume it is okay for me to post mine.

Code:

// ==UserScript==
// @name         Frank's Chatbot
// @namespace    http://tampermonkey.net/
// @version      0.2
// @description  try to take over the world! maybe some musical stuff, too
// @author       Frank
// @match        https://onlinesequencer.net/chat/
// @grant        none
// @run-at       context-menu
// ==/UserScript==

(function() {
   'use strict';
   var botKeyword = '!do ';
   var lastChatId;
   var lastUser;
   function Command(name, desc, code){
       this.name=name;
       this.desc=desc;
       this.code=code;
       this.toString = () => this.name
   }
   var commands = {
       me: new Command('me', '!do me --> You are ...', function(command){
           post('You are ' + lastUser)
       }),
       random: new Command('random', '!do random --> ##random (in key)', function(command){
           $.get('https://onlinesequencer.net/ajax/random.php', function(r){
               post('##'+r.slice(r.search(/="\/\d/)+3,r.search(/\d" o/)+1))
           })
       }),
       stop: new Command('stop', '!do stop --> stops bot', function(command){
           clearInterval(clearId);
           post('Stopped.')
       }),
       help: new Command('help', '!do help | [command] --> gives desc. of [command]', function(command){
           var helped = commands[command[1]]
           if(typeof command[1] == 'undefined') post('!do [command] | [arg1] | [arg2] ... "!do help | help" for help on help. All Commands: ' + Object.keys(commands).join(', '))
           else post(helped?helped.desc:'Unknown command. Cannot help.')
       })
}

   function tickBot() {
       //get latest chat message
       var lastChat = document.getElementById('chat_table').lastElementChild;

       //check if it is new
       if (lastChat.id == lastChatId) {
           lastChatId = lastChat.id;
           return
       } else {
           lastChatId = lastChat.id
       }

       //parse the chat message
       lastUser = lastChat.children[0].children[0].innerText;
       var lastMessage = lastChat.children[1].innerText;

       //logic and send
       if (lastMessage.substr(0, botKeyword.length) == botKeyword) {
           var command = lastMessage.slice(botKeyword.length).split(' | ');
           if(commands[command[0]]) commands[command[0]].code(command, lastUser)
           else post('Invalid command. "!do help" for help.')
       }
   }

   function post(message) {
       var message1 = '​' + message
       if (message1.length > 256) return post('Tried to post; message too long.')
       $.post('xmlhttp.php?action=ajaxchat_send', {
           message: message1
       })
   }

   if($.post) {post('Started. "!do help" for help.');
               var clearId = setInterval(tickBot, 500)
               }
   else console.log('Not in IFrame')
})()

You can also comment suggestions for me or your own tweaks to my code.

What commands do you have planned for the future? I'm not sure how much a bot can help with making or listening to music. Maybe some quick references for scales and chords, motif generation etc?

[Eandrew]

Maybe you could add a command that selects and displays a sequence from the profile of the person who uses the command, based on how many plays or notes it has, or just randomly. That would be lit

[Frank]

Both suggestions so far are surprisingly applicable and amazing.
Current changelog:
Added Eandrew's suggestion.

Now use a neural network, and train it on the chat logs so you can generate entire conversations! http://karpathy.github.io/2015/05/21/rnn-effectiveness/

how do you use this?
