Framework for R9K and other bots.

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.

addMessageTrigger('!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.
