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.

Public Instance

Here is a link you can use to invite a public instance run by @frozolotl: https://discord.com/oauth2/authorize?client_id=1183804211264225301&permissions=3072&scope=bot

Note: the bot may be limited from joining more servers because we require the message content (since slash commands don't support code blocks) and Discord denied verification, so we are limited to 100 servers. Accordingly, we request that you remove the bot from your servers if you are not using it anymore.
