🐺 FenrirBot

A simple Discord bot for Illidan's Fenrir guild.

This is version 0.1.0 of this Discord bot. We haven't quite decided on all of the tasks we would like for it to perform. Right now, the purpose is to give guild members a quick set of commands to access guild information on the fly. A guild member could use the command !raid and the bot would return the current raid times for the guild.

!raid command

Prerequisites

To connect your bot, you're going to need create a new application from within the Discord Developer Portal. Discord.py has a nice little guide to walk you through the process if you need help.

You'll need somewhere to run a small .py application. We used Raspberry Pi 3 Model B+ so we could quickly get a proof of concept of our bot out.

Hardware

Fenrir is a really small guild, so we didn't need anything fancy to get FenrirBot up and running - especially having such a small scope with release 0.1.0.

I have a Raspberry Pi 3 Model B+ sitting on my desk, that's it!

Software

I have the Pi running the latest version of Raspbian Stretch Lite (June 2018 release at the time of this writing). The version of shipped with Python 3.5.3, but I went ahead and upgraded to 3.6.6 (since I've had issues using pip on the Pi running 3.7 in the past & for this, it's good enough).

Prerequisites for Python 3.6.X

Install the latest build tools.

$ sudo apt-get install build-essential tk-dev
$ sudo apt-get install libncurses5-dev libncursesw5-dev libreadline6-dev
$ sudo apt-get install libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev
$ sudo apt-get install libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev  

You should already have most of these, but libssl-dev is important for making sure pip would be working once I upgraded to 3.6.X. Better safe than sorry I suppose.

If one of the packages above cannot be found, try a newer version number (e.g. libdb5.4-dev instead of libdb5.3-dev).

Optional: Purge the source code and previously installed packages.

$ rm Python-3.6.6.tgz
$ sudo apt-get --purge remove build-essential tk-dev
$ sudo apt-get --purge remove libncurses5-dev libncursesw5-dev libreadline6-dev
$ sudo apt-get --purge remove libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev
$ sudo apt-get --purge remove libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev
$ sudo apt-get autoremove
$ sudo apt-get clean

Getting the latest version of Python

Grab the latest version of Python. I'm using Python 3.6.6 for this project.

$ get https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz

Extract the .tgz with $ tar xzvf Python-3.6.6.tgz

Go into the directory with $ cd Python-3.6.6/

Run $ ./configure to check for dependencies, this should only take a few minutes.

Compile using $ make, this could take quite some time so be patient.

Now we'll install Python 3.6.6 with $ sudo make install

Last but not least, reboot $ sudo reboot.

Configure the Discord bot

Install the latest version of Discord.py.

$ python3 -m pip install -U discord.py

Now we'll setup a directory for FenrirBot.

$ mkdir ~/fenrirbot

Move into the directory you just created.

$ cd ~/fenrirbot

Create a new file.

$ touch bot.py

Edit that file with nano.

$ nano bot.py

You can copy/paste our simple code to get started. Just be sure to replace TOKEN with your bot's token to get things working.

import discord
from discord.ext import commands

TOKEN = 'TOKEN'

description = '''FenrirBot | For the Horde!'''
bot = commands.Bot(command_prefix='!', description=description)

@bot.event
async def on_ready():
    print('Logged in as')
    print(bot.user.name)
    print(bot.user.id)
    print('------')


@bot.command()
async def raid():
    """will display our current raiding schedule."""
    await bot.say("We'll be raiding every Monday & Wednesday at 9:00PM EST")

@bot.command()
async def pug():
    """will give you the URL to invite temporary members to the Discord Server."""
    await bot.say("Invite PUG members using: LINK REVOKED")

@bot.command()
async def hello():
    """FenrirBot will respond back."""
    await bot.say("Hello, Champion!")


bot.run(TOKEN)

Save the edits you've made in nano with CTRL+X and y.

Now you can run your bot! $ python3 bot.py You can also run using $ nohup python3 -u ~/fenrirbot/bot.py &. nohup will allow the task to continue running after you terminate your SSH connection. & is going to run the task in the background to keep the terminal open for use. There is also an issue where the script auto-terminates after 2-3 hours, I've opened Issue 1 but I haven't had time to work on it. Learn more in the issue on setting up a Cron job to keep the bot running.

Give it a whirl

Now your bot should show an online status.

Online Status

Quickly test your bots response by issuing the !help command.

Thanks for checking out this simple project for Fenrir.
