Execute sandboxed code on Discord

Invite

Want a new language?

Create a language request.

Development

1. Copy .env.example to .envrc and fill in the values.
2. Install sqlx-cli via cargo.
3. Run sqlx db create to create the database.
4. Run sqlx migrate run to create the database schema.
5. Run cargo run to start the bot. (optionally use cargo make dev to run with hot reloading)

Development (tcp server)

If you're developing a new language and don't want to run the bot, you can run the tcp server with cargo run --bin tcp and connect with nc localhost 8080.

The .env file requirements are the same except DISCORD_TOKEN can be any random string.

Deployment (Linux only)

You have to install gVisor as a runtime for docker to provide an additional isolation boundary between the containers and the host kernel.
