Typst Bot

A Discord bot that renders Typst code.

Built with poise so it has all the goodies like edit tracking, typing status, and automatic help generation.

Hosting

The bot uses two binaries:

• bot: connects to Discord and processes messages
• worker: receives requests, interacts with Typst, responds

bot will automatically spawn worker, so you only need to run bot.

To set up the working environment, create a directory with the following items:

• fonts: Copied from the repo. Make sure you have Git LFS set up so the fonts are downloaded properly. The fonts no longer use LFS due to GitHub's new transfer limits.
• worker: The worker binary, copied/hardlinked from the target directory after building.
• bot: The bot binary, copied/hardlinked from the target directory after building. (This doesn't need to be in this directory, but having everything in one place simplifies things.)
• db.sqlite: You can just touch this, but the bot needs to be able to write to it.

To run, CD into this directory, set DISCORD_TOKEN to your bot token, set CACHE_DIRECTORY and DB_PATH to suitable locations, and run the bot binary (not the worker binary that's also in the directory).

Docker

There is a Dockerfile and docker-compose.yml for running the bot inside a Docker container.

To set up the bot with Docker, create a .env file like the following:

DISCORD_TOKEN=YourBotTokenHere

and start the container with docker compose up -d.
