Reminder Bot for Discord.

How do I use it?

I offer a hosted version of the bot. You can invite it with: https://invite.reminder-bot.com. The catch is that repeating reminders are paid on the hosted version of the bot. Keep reading if you want to host it yourself.

You'll need rustc and cargo for compilation. To run, you'll need Python 3 still (due to no suitable replacement for dateparser in Rust)

Compiling

Install build requirements: sudo apt install gcc gcc-multilib cmake libssl-dev build-essential

Install Rust from https://rustup.rs

Reminder Bot can then be built by running cargo build --release in the top level directory. It is necessary to create a folder called 'assets' containing an image file with its name specified in the environment as WEBHOOK_AVATAR, of dimensions 128x128px to be used as the webhook avatar.

Compilation environment variables

These environment variables must be provided when compiling the bot

DATABASE_URL - the URL of your MySQL database (mysql://user[:password]@domain/database)
WEBHOOK_AVATAR - accepts the name of an image file located in $CARGO_MANIFEST_DIR/assets/ to be used as the avatar when creating webhooks. IMPORTANT: image file must be 128x128 or smaller in size

Setting up Python

Reminder Bot by default looks for a venv within it's working directory to run Python out of. To set up a venv, install python3-venv and run python3 -m venv venv. Then, run source venv/bin/activate to activate the venv, and do pip install dateparser to install the required library

Environment Variables

Reminder Bot reads a number of environment variables. Some are essential, and others have hardcoded fallbacks. Environment variables can be loaded from a .env file in the working directory.

Required Variables

DATABASE_URL - the URL of your MySQL database (mysql://user[:password]@domain/database)
DISCORD_TOKEN - your application's bot user's authorization token

Other Variables

MIN_INTERVAL - default 600, defines the shortest interval the bot should accept
LOCAL_TIMEZONE - default UTC, necessary for calculations in the natural language processor
SUBSCRIPTION_ROLES - default None, accepts a list of Discord role IDs that are given to subscribed users
CNC_GUILD - default None, accepts a single Discord guild ID for the server that the subscription roles belong to
PYTHON_LOCATION - default venv/bin/python3. Can be changed if your Python executable is located somewhere else
THEME_COLOR - default 8fb677. Specifies the hex value of the color to use on info message embeds
DM_ENABLED - default 1, if 1, Reminder Bot will respond to direct messages
