🧪 Installation

Download and install dependencies

Clone the repo

git clone https://git.waifuism.life/waifu/kemoverse.git
cd kemoverse

Setup a virtual environment (Optional, recommended)

python3 -m venv venv
source venv/bin/activate

Install project dependencies via pip

python3 -m pip install -r requirements.txt

Setup config file

A sample config file is included with the project as a template: example_config.ini

Create a copy of this file and replace its' values with your own. Consult the template for more information about individual config values and their meaning.

Config files are environment-specific. Use config_dev.ini for development and config_prod.ini for production. Switch between environments using the KEMOVERSE_ENV environment variable.

cp example_config.ini config_dev.ini
# Edit config_dev.ini

Setup database

To set up the database, run:

KEMOVERSE_ENV=dev python3 setup_db.py

Run the bot

KEMOVERSE_ENV=dev ./startup.sh

If all goes well, you should now be able to interact with the bot.

Running in production

To run the the in a production environment, use KEMOVERSE_ENV=prod. You will also need to create a config_prod.ini file and run the database setup step again if pointing prod to a different database. (you are pointing dev and prod to different databases, right? 🤨)

Updating

To update the bot, first pull new changes from upstream:

git pull

Then run any database migrations. We recommend testing in dev beforehand to make sure nothing breaks in the update process.

Always backup your prod database before running any migrations!

# Backup database file
cp gacha_game_dev.db gacha_game_dev.db.bak
# Run migrations
KEMOVERSE_ENV=dev python3 setup_db.py
