An experimental Robot 9000 for Discord. Currently supports tracking and deleting duplicate messages, clearing specific channels after a given time, and responding to specific trigger phrases.

Note: requires node.js v8.

First, go to the Discord developer documentation, create an app and get your token.

export DISCORD_TOKEN=<token>
npm install
node index.js

To add the bot to your server, insert the client ID into this URL https://discordapp.com/oauth2/authorize?client_id=CLIENT_ID_GOES_HERE&scope=bot&permissions=0 and paste it into your browser of choice.

The bot as it is currently has a lot of things tuned to my personal discord server, which I plan to refactor away at some point, in the mean time, you will probably need to head into the code and take these out if they end up annoying you.

A The trigger can be one of the following types:

• String The callback will be triggered if the message matches the String exactly
• RegExp If the message matches the RegExp, the callback will be triggered, the callback argument will include the list of matches returned by String.match()
• Array All array elements are treated as separate triggers

A function that will be called if the trigger is matched.

The callback has one argument, an object containing the following fields:

• user the user that triggered this event
• userId that users, id
• channelId the id of the channel
• message the message that triggered this event
• matches any matches if the trigger was a regular expression
• event the full event from discord.io that triggered this event
• bot this discord.io client object, can be used to respond asynchronously

If the callback returns a String, it will be sent as a message to the channel this event was triggered from. If you want to respond to an event asynchronously, you can use the bot object to send a message.

addMessage('!someTrigger', (opts) => {
  returnsAPromise().then(result => opts.bot.sendMessage({
    message: result,
    to: opts.channelId,
  }));
});

See the Discord developer docs, or the docs for discord.io, the library that powers this bot.
