discord-bot

Version 2 of a cog-based framework for discord.js bots

Features

• Ping bot for help
• Modulur cog / hook system
• Lots of builtin cogs
• Bootifull embed UI
• Automatic slash command builder
• Automatic help builder
• Can in fact cook pancakes (Discord is lying to you)

Usage

Run ./run.sh or ./index.js with nodejs

Config

Config is located in conf.json, the structure of a config file can be found in conf.def.json

Config is split between files where main is for the main file whilst others like goodmorning are for cogs

Help for configuration for other cogs can be found at the top of their files

Main config

Key	Description
token	The discord token to use (also known as OAuth2 Client Secret)
prefix	The command prefix to use
admins	Array of string IDs of admins
activity	Activity text of the bot

This next part is for developers :)

Globals

Stuff that you can use everywhere

Modules

Both fs and https are included

Custom log

When possible use the custom log global instead of console.log, here are the functions available

Doc String	Description
log(msg: String) => undefined	Print a msg
log.warn(msg: String) => undefined	Print a warn msg
log.error(msg: String) => undefined	Print an error msg
log.fake(...args: *) => String	Same arguments as console.log, outputs the string which would've been printed (includes escape codes) (don't use this) (ever)
log.time() => String	Return the current time as a string (internal)
log.raw(color: Integer, msg: String)	Print a message with a colored timestamp (internal)

Discord.js

Discord.js is included as dc with added parts

Command parameter types are in dc.XXX. You can get a string name for these using dc.typename[dc.XXX].

dc.PermissionFlagsBits is aliased to dc.Permissions

Util

Doc String	Description
util.hash(s: String) => hash: Integer	Hash a string
util.levdis(a: String, b: String) => dis: Integer	Get the levenhtein distance between two strings
util.levdisclosest(array: Array<String>, target: String, cutoff: Integer) => Array<String>	Sort a array by levdis to a target (items further than cutoff are removed)
util.levdisuserclosest(array: Array<User / GuildMember>, target: String, cutoff: Integer) => Array<String>	Sort an array of users by levdis to a target (items further than cutoff are removed)
util.fetch(url: String) => Promise<String>	A url fetching tool when bultin fetch and http don't work

Client

Where all client-related shenanigans are stored, refer to docs for more info

Doc String	Description
client.cmds	Dictionary of commands
client.cogs	Paths of loaded cogs
client.hooks	All hooks
async client.cmds.serialize() => Array<Command>	Turn the commands in client.cmds into a single object which can be accepted by the discord API
async client.cmds.push(Array<Command>)	Push commands to the discord API
client.cogs.load(name: String) => Boolean or undefined	Load a cog, a bool return value represents whether the cog was loaded, an undefined means theres an error preventing the cog from loading (doesn't exist / disabled) (extension name included)
client.cogs.unload(name: String) => undefined	Unload a cog (extension name included)
client.hooks.add({event: String, priority: Number, func: async function => Boolean}) => undefined	Add a hook
client.hooks.sub({event: String, priority: Number, func: async function => Boolean}) => undefined	Sub a hook

Cogs

Cogs can be found in ./cogs/*.js, this is the format of a cog

/* cogname.js
Config
"cogname": {
	"name": <value>
}
Requires
nop: to do something useless
*/

module.exports.disabled = false; // optional

module.exports.desc = "<what I does>"; // optional

module.exports.hooks = { // optional
	...
};

module.exports.cmds = { // optional
	...
};

module.exports.onload = async function() { // optional, runs on cog load
	// Do all initialization of config and other stuff here
};

module.exports.onloadready = async function() { // optional, runs on cog load after bot is initialized
	// Fetch channels, servers, users, etc
};

module.exports.onunload = async function() { // optional, runs on cog unload
	// Cleanup any timers, callbacks, etc
};

module.exports.tick = async function() { // optional, runs every ~10m
	// Save any data, do random tasks, etc
};

Commands

In module.exports.cmds you can place any amount of commands in this format

"commandname": {
	"desc": "What I do",
	"func": async function (args) {
		...
	}
}

Here are some extra options admin: Whether a user must be an admin (in conf.main.admins) dm: Whether this command can be used in DMs or not hide: Whether the calling of this command is hidden args: Array of arguments (look below for more info)

args: [
	// A string
	[dc.TEXT, "name", "Mother's maiden name", true, 5, 20],
	// Either true or false (NOT IMPLEMENTED)
	[dc.BOOL, "violence", "Whether violence should be used", true]
	// A whole number
	[dc.INT, "bet", "How much money to bet", false, 100],
	// A(n) (un)whole number
	[dc.NUMBER, "chance", "ID of the server", false, -3.2, 5],
	// A user in the channel (found first by ID then by a fuzzy search)
	[dc.USER, "user", "User to make immortal", false],
	// A role in the channel (NOT IMPLEMENTED)
	[dc.ROLE, "role", "Role to allow", true],
	// A channel in the server (NOT IMPLEMENTED)
	[dc.CHANNEL, "channel", "Channel to nuke", true],
	// A server the bot is in (NOT IMPLEMENTED)
	[dc.SERVER, "Server", "Gift location", true],
	// Same as text but must be one of these options (fuzzy search used)
	[dc.CHOICE, "animal", "Fav animal", true, ["Cat", "Dog", "Perry the Platypus"]]
	// Text not seperated by spaces (must come last)
	[dc.BIGTEXT, "prompt", "Prompt for AI", true, undefined, 200],
]
// General format:
args: [
	[dc.TYPEOFARG: Enum, "name": String, "Description": String, required: Boolean, min: Number, max: Number]
]

In the command function, this refers to the (message)[https://discord.js.org/#/docs/discord.js/main/class/Message] or (interaction)[https://discord.js.org/#/docs/discord.js/main/class/CommandInteraction] object with some extras. These extras are: this.author.isNotPerson: Whether the author is a bot, system or webhook message or just a user this.author.isAdmin: Whether the author is a bot admin (defined in conf.main.admins) async this.embedreply(Object<opts>) => undefined: Send an embed reply async this.errorreply(msg: String) => undefined: A shorthand for an error message embedreply async this.webhookreply(user: dc.GuildMember, msg: String) => undefined: Send a message as a different user (sends a message in DMs)

Here is an explanation of the most complicated given function, and as such I'm going to break it down a bit more. Here is the semi-formal syntax for reference

async this.embedreply(Object<{
	msg: String
	title: String
	color: Array<Integer>
	fields: Array<Object<{
		name: String,
		value: String
	}>>
	thumb: Url (String),
	image: Url (String),
	url: Url (String),
}>) => undefined

Don't be scared! look at this example instead

await this.embed({
	"title": "Hello World",
	"msg": "I'm a bot!"
});

See? ez.

Hooks

In module.exports.hooks you can place any amount of hooks in this format

"commandname": {
	"event": "<event name>",
	"priority": 0,
	"func": async function () {
		...
	}
}

Explanation of each param: event: The name of the event to hook to, you can see them (here)[https://discord.js.org/#/docs/discord.js/main/class/Client] -> events priority: The (order) priority of this hook (-10, 0, 10 are normal) func: The function, this is the event object, return true to "consume" this event
