Icarus - Custom Discord bot for the LDSG Community

Icarus is built in Node.js for the LDS Gamers community. It runs on the Augur framework, utilizing the Discord.js library.

Pull requests from the community are welcome.

The Augur Handler

Within your base file, require augurbot and create a new instance of AugurClient:

const {AugurClient} = require("augurbot");
const client = new AugurClient(config, options);

client.login();

The AugurClient will create the Discord Client, log it in using the token provided in config.token, listen for events, and process commands. Any gateway intents are automatically calculated based on config.events.

The config Object

Minimum required properties in config include:

• events (array): An array of discord.js events to process, including message and messageUpdate, if your bot will be processing message commands. Gateway intents will be automatically calculated based on the events supplied.

Additional optional properties include:

• db (object): An object, including a model property which is the path to your database model, relative to the base file.

• prefix (string): A default prefix for commands. Defaults to !.

• processDMs (boolean): Whether to process messages in DMs. Defaults to true.

• token (string): Your bot's Discord token to log in. If provided in the config object, it does not need to be passed when client.login() is called. If omitted, it must be passed with client.login(token) when logging in.

• Any other properties you wish to be able to access from your command modules.

The options Object

The options object is optional, but may include:

• clientOptions (object): An object containing options to be passed to the new Discord.Client(). Gateway intents are automatically calulated based on config.events. If you would like to override the calculated intents, provide your own intents as usual for Discord.js.

• commands (string): A directory, relative to the base file, containing any command modules you wish to automatically load.

• errorHandler: A function accepting error and message as its arguments. This will replace the default error handling function.

• parse (async function): An asynchronous function accepting message as its argument, returning an object with command and suffix properties. This will replace the default parsing function. (Useful in case different servers use different prefixes, for example.)

AugurClient Properties

Properties of the Handler class:

• augurOptions (object): The options object passed to the client upon initialization.

• clockwork (ClockworkHandler extends Collection):

  A collection of functions to be run by an interval.

  • register(Module): Registers clockwork functions from a Module. Automatically called by client.moduleHandler.register(Module).
  • unload(filepath): Unload a clockwork function from memory. Automatically called by client.moduleHandler.unload(filepath).

• commands (CommandHandler extends Collection):

  A collection of commands, keyed by command name.

  • aliases (Collection): Collection of commands, keyed by alias.
  • client (AugurClient): The client.
  • commandCount (Number): Integer of how many commands have been executed via commands.execute().
  • execute(commandName, message, suffix) (async function): Execute a command function. Automatically called by the event handler.
  • register(Module) (function): Registers commands from a Module. Automatically called by client.moduleHandler.register(Module).

• config: The config object passed to the Handler.

• db: Your loaded database model.

• events (EventHandler extends Collection):

  A collection of event handlers, keyed by event then keyed by filepath.

  • register(Module): Registers event handlers from a Module. Automatically called by client.moduleHandler.register(Module).

• moduleHandler (ModuleHandler):

  Helper functions for loading/unloading/reloading Augur Modules.

  • register(Module, data): Register the module with optional data.
  • reload(filepath): Reload a module from a filepath, reregistering the module with data supplied by the command's .unload() function.
  • unload(filepath): Unload a module from memory.

AugurClient Methods

Methods of the Handler class:

• errorHandler(error, message): Error handling function.

• parse(message): Parse a message into its command name and suffix. Returns an object containing command (string) and suffix (string).

Command File Structure

The basic file structure:

const Augur = require("augurbot");
const Module = new Augur.Module();

// Add commands, event handlers, etc. as necessary.

module.exports = Module;

In between, you can add one or more commands and event handlers, as well as a clockwork and unload function.

Module properties include:

• config: Contents of the config object loaded with the Handler.

• db: The loaded database model.

• client: The Augur client which loaded the command module.

All of the following methods are chainable:

Clockwork

The function passed to the .setClockwork() method should return an interval which will continue to run in the background. The interval is cleared and reloaded when the module is reloaded. Note that the clockwork function is run after the intialization function.

Module.setClockwork(function() {
  return setInterval();
});

Commands

The .addCommand() function defines a new bot command.

Module.addCommand({
  name: "commandname", // required
  aliases: [], // optional
  syntax: "", // optional
  description: "", // recommended
  info: "", // recommended
  hidden: false, // optional
  category: "General", // optional
  permissions: (msg) => true, // optional
  process: (msg, suffix) => {} // required
});

Events

The .addEvent() method adds an event handler for the various Discord.js events.

Module.addEvent("eventName", function(...args) {});

Initialization

The .setInit(data) method accepts a function to run on module initialization. The data parameter will have a null value on the first run, and will contain the returned by the function defined with the .setUnload() method on subsequent reloads of the module.

Module.setInit(function(data) {});

Unloading

The function passed to the .setUnload() method will be run when unloading or reloading the module.

Module.setUnload(function() {});
