# tavolo

A platform for multiplayer card games. Three games are included:
**scopone scientifico** — the four-player, fixed-partnership Italian card
game — **briscola**, in its classic two-player and four-player
partnership (*briscola a quattro*) variants, and **briscola chiamata** —
the five-player variant with a calling auction and a secret partner:

- **`server/`** — backend: Python + [kaya](https://github.com/woggioni/kaya)
  framework, OIDC login, live games in Redis, match statistics in Postgres.
  A monorepo of four distributions sharing the `tavolo` namespace: the
  game-independent `tavolo-platform`, the `tavolo-scopone` and
  `tavolo-briscola` games, and the `tavolo-app` composition root wiring
  them together. See [server/README.md](server/README.md).
- **`web/`** — frontend: Rust + [Sycamore](https://sycamore.dev) compiled to
  WebAssembly, built with [Trunk](https://trunkrs.dev) and styled with
  [Bootstrap](https://getbootstrap.com) 5.3 (MIT, vendored under
  `web/vendor/` so builds work offline) plus the custom felt theme in
  `web/theme.css`. 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**: scopone players see how each category was won
(carte, denara, settebello, primiera, scope — plus napola and asso
pigliatutto when enabled), briscola players see the deal's points and any
*patta*; both see 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. Briscola chiamata
plays a single deal per match, so it goes straight from the last trick to
the final scoring screen; a 60–60 *patta* is replayed immediately.

## 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 (choosing among the legal captures when the
rules require a capture), so one absent player cannot stall the table.
Briscola chiamata arms the same countdown for its auction bids and for
the auction winner's called-card choice (auto-bid or auto-pass, then a
random suit of the won rank).

## Watching

Anyone who has the game URL (`/game/<id>`) can watch, logged in or not:
spectators see the table, the score and every player's captured cards
(and scope for scopone), but never a hand and never the join code. In
briscola chiamata they also see no role labels and no side totals until
the called card is played, so the secret partner stays secret. The
"Copy watch link" button in the waiting room and in the game HUD copies
the URL to share. A spectator who opens the URL before the match starts
sees a "game not started yet" waiting room.

## Development

Backend (from `server/`):

```sh
cd server
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
.venv/bin/pip install -e ./packages/tavolo-platform -e ./packages/tavolo-scopone -e ./packages/tavolo-briscola -e './packages/tavolo-app[dev]'
.venv/bin/python -m unittest discover -s tests -t .
.venv/bin/python -m unittest discover -s packages/tavolo-platform/tests
.venv/bin/python -m unittest discover -s packages/tavolo-scopone/tests
.venv/bin/python -m unittest discover -s packages/tavolo-briscola/tests
```

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_0_PROVIDER=default \
OIDC_0_ISSUER=http://localhost:8180/tavolo \
OIDC_0_CLIENT_ID=tavolo \
OIDC_0_REDIRECT_URI=http://localhost:8080/auth/default/callback \
OIDC_0_POST_LOGIN_REDIRECT=http://localhost:8000/ \
OIDC_0_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.
