Example:

const Tasker = require("./src/Bot.js")
const Bot = new Bot({

Bot.start();

Tasks System

Tasks

Commands are referred to as "tasks". To create a new task, place a javascript file with it's file name being the task's alias in your tasks directory. It is a module that will be read when the bot is launched.

// mytask.js
module.exports = {
    name: "My Task",                            // Your task's name displayed on the help listings.
    desc: "This is my task",                    // Your task's description displayed on the help listings.
    help: "This task says Hello World!",        // Your task's help text displayed on the help menu.
    preq: ["ServerOnly", "HasElevatedPerms"],   // The bot's prerequisite flags when checking permissions.
    perm: ["MANAGE_MESSAGES"],                  // Discord's permission flags when checking permissions.
    task: (Bot, msg, args) => {                 // The task performed when the caller has permission.
        msg.channel.send("Hello World!");
    }
}

Using the example above, you can use !mytask in Discord to run the task.

Task Groups

Subcommands are referred to as "task groups". To create a task group, create a new folder with the group's alias as it's name inside your tasks directory and place a settings.json for its metadata. You can then add tasks inside it.

// mygroup/settings.json
module.exports = {
    "name": "My Task Group",                    // Your task group's name displayed on the help listings.
    "desc": "This is my task group"             // Your task group's description displayed on the help listings.
}
// mygroup/mytask.js
// ...refer to the example above

Using the example above, you can use !mygroup mytask to run the task from within a task group.

Permission System

The bot has a permission system in order to check if the user or the bot has rights in running a command.

Prerequisite Flags

• DMChatOnly - The task can only be ran in a direct message.
• ServerOnly - The task can only be ran inside a guild server channel.
• BotOwnerOnly - The task can only be ran by the bot and the owner/s.
• HasElevatedPerms - The task can only be ran inside a guild and the caller has permissions.
• ServerOwnerOnly - The task can only be ran inside a guild and the caller is the guild's owner.

Permission Flags

Please refer to discord.js documentation for the list of useable flags and its description.

Event Tasks

The bot can attach as many event listeners as it can. Please refer to discord.js documentation for the list of events emitted.

To attach your own, create a new javascript file and require it in your main javascript file.

// event.js
module.exports = {
    name: "My Event",               // Your unique event name
    event: "message",               // The listened event
    task: (msg) => {                // The task ran when the event is emitted with the arguments being what is passed onto it.
        msg.channel.send("Hello!");
    }
}
// bot.js
// ..refer to the example above first.
var myEvent = require("event.js");
Bot.loadEvent(myEvent);

Job Tasks

The bot can do cronjobs. Cronjobs are only ran on a the specified time of day.

To create your own, create a new javascript file and require it in your main javascript file.

// job.js
module.exports = {
    name: "My Job",                 // Your unique job name
    time: "00 00 * * * *",          // The cron pattern. This example is ran every hour.
    timezone: "Asia/Tokyo",         // The timezone
    task: (Bot) => {                // The task ran when the event is emitted with the arguments being the bot itself.
        Bot.shutdown();
    }
}
// bot.js
// ..refer to the example above first.
var myJob = require("job.js");
Bot.loadJob(myJob);

• Please refer to crontab.js for the available cron patterns.
• Please refer to momentjs for the available timezones.

Tasker Properties

Tasker has properties to be set alongside discord.js to make use of it's utilities.

• tasks - The tasks directory in glob pattern. Please refer to glob documentation.
• token - The application's token provided by Discord.
• prefix - The prefix when running tasks.
• ownerID - An array of strings of all IDs of the owners.
• timeout - A number in seconds as cooldown in between requests.
• debug - A boolean to enable discord.js' debug events.
• logFile - The directory where to log and save the bot's logs.

Tasker Methods

Tasker also provides utility methods.

.start()

Use this when starting your bot. Loads all tasks and logs the bot in. Returns the bot itself.

.reloadTasks()

Reloads the tasks directory. Useful when appending new tasks without the need of restarting the bot itself.

.loadEvent(event)

• event - The event's unique name

Loads an event. See the example above.

.destroyEvent(event)

• event - The event's unique name

Destroy's the event and stops listening for it.

.loadJob(job)

• job - The job's unique name

Loads a job. See the example above.

.doJob(job)

• job - The job's unique name

Force runs a job.

.destroyJob(job)

• job - The job's unique name

Destroys and stops the job.

.invoke(channel, content, user)

• channel - The guild channel.
• content - The content as if sent by a user without the prefix.
• user - The user invoking the command as. Defaults to the bot itself when not provided.

This simulates a task being ran with permissions still being applied to it. Triggers an error when the user can't invoke it.

.shutdown()

Gracefully shuts down the bot.
