# tavolo

A platform for multiplayer card games. The first game is **scopone
scientifico** — the four-player, fixed-partnership Italian card game:

- **`server/`** — backend: Python + [kaya](https://github.com/woggioni/kaya)
  framework, OIDC login, live games in Redis, match statistics in Postgres.
  See [server/README.md](server/README.md).
- **`web/`** — frontend: Rust + [Sycamore](https://sycamore.dev) compiled to
  WebAssembly, built with [Trunk](https://trunkrs.dev). Card images are the
  CC0 *woodcut napoletane* deck traced from a 1902 Naples print
  ([SONDLecT/woodcut-napoletane](https://github.com/SONDLecT/woodcut-napoletane)).

## Run the whole stack

```sh
docker compose up --build
```

Postgres, Redis, a mock OIDC provider (test users `alice`, `bob`, `carol`,
`dave`), the database migrator and the app all come up together. The app —
frontend and API — listens on `http://127.0.0.1:8080`.

Because both the browser and the app talk to the OIDC issuer at
`http://mockoauth:8180/tavolo`, add a host entry once:

```sh
echo "127.0.0.1 mockoauth" | sudo tee -a /etc/hosts
```

## Between hands

When a hand ends but the match is not decided, the game pauses on a
**scoring summary screen**: every player sees how each category was won
(carte, denara, settebello, primiera, scope) with the running totals and
must click "Understood" before the next hand is dealt. If someone is away
the next hand is dealt automatically after `HAND_ACK_TIMEOUT_SECONDS`
(default 30s). The match-ending hand is explained on the final screen.

## On your turn

Every turn shows a countdown (`TURN_TIMEOUT_SECONDS`, default 30s). If a
player does not move — disconnected or fallen asleep — the server plays a
random legal card for them (randomizing among the legal captures when the
rules require a capture), so one absent player cannot stall the table.

## Development

Backend (from `server/`):

```sh
cd server
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
.venv/bin/pip install -e '.[dev]'
.venv/bin/python -m unittest discover -s tests -t .
.venv/bin/mypy src
```

Frontend (from `web/`), with the backend running on :8080:

```sh
cd web
trunk serve          # SPA on http://localhost:8000, /api /auth /ws proxied
```

Trunk proxies `/api`, `/auth` and `/ws` to `127.0.0.1:8080` (see
`web/Trunk.toml`). For the login redirect to land back on the dev server,
run the backend with:

```sh
OIDC_POST_LOGIN_REDIRECT=http://localhost:8000/ \
OIDC_POST_LOGOUT_REDIRECT=http://localhost:8000/ \
  .venv/bin/granian --host 127.0.0.1 --port 8080 tavolo.app:app
```

Card images are committed under `web/assets/cards/`; `web/fetch-cards.sh`
re-downloads them if needed.
