# Discord-reminder-bot
Discord bot that allows you to set reminders.
<sup>Theme is [DiscordNight by KillYoy](https://github.com/KillYoy/DiscordNight)<sup>
## Usage
!remind <message_date> <message_reason>
message_date can be anything that is a date or time. For example:
* `in 2 days`
* `August 14, 2021 EST`,
* `tomorrow`
* `1 เดือนตุลาคม 2025, 1:00 AM`
message_reason is the message the bot will send at that time.
## Environment Variables
* `BOT_TOKEN` - Discord bot token ([Where to get one](https://discord.com/developers/applications))
* `TIMEZONE` - Your time zone ([List of time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones))
* `SQLITE_LOCATION` - (Optional) Where to store the database. Docker users need to change this to "/data/jobs.sqlite"
* `LOG_LEVEL` - Can be CRITICAL, ERROR, WARNING, INFO or DEBUG
## Installation
You have two choices, [install directly on your computer](#Install-directly-on-your-computer) or using [Docker](#docker-compose-with-env-file).
[Docker Hub](https://hub.docker.com/r/thelovinator/discord-reminder-bot) | [docker-compose.yml](docker-compose.yml) | [Dockerfile](Dockerfile)
### Install directly on your computer
* Install latest version of Python 3 for your operating system

* `python -m venv .venv`
* Activate virtual environment:
* Windows: `.\.venv\Scripts\activate`
* Not windows: `source .venv/bin/activate`
* Install requirements
* `pip install -r requirements.txt`
* Rename .env.example to .env and fill it out.
* Start the bot (inside the virtual environment if you made one):
* `python main.py`
### Start the bot when your Linux server boots
* Keep services running after logout
* `loginctl enable-linger`
* Move service file to correct location (You may have to modify WorkingDirectory and/or ExecStart)
* `cp discord-reminder-bot.service ~/.config/systemd/user/discord-reminder-bot.service`
* Start bot now and at boot
* `systemctl --user enable --now discord-reminder-bot`
#### systemd examples

* To monitor the logs of the container in real-time: `docker logs -f discord-reminder-bot`
## Updating
### Via Docker Compose
* Update all images: `docker-compose pull`
* or update a single image: `docker-compose pull discord-reminder-bot`
* Let compose update all containers as necessary: `docker-compose up -d`
* or update a single container: `docker-compose up -d discord-reminder-bot`
* You can also remove the old dangling images: `docker image prune`
### Via Docker Run
* Update the image: `docker pull thelovinator/discord-reminder-bot`
* Stop the running container: `docker stop discord-reminder-bot`
* Delete the container: `docker rm discord-reminder-bot`
* Recreate a new container with the same docker run parameters as instructed above (if you mapped `/home/botuser/data/` to your computer your `jobs.sqlite` file and reminders will be preserved)
* You can also remove the old dangling images: `docker image prune`
