# Rats with Gats Remote Play (`pirats`)
A web-based remote play companion app for the tabletop roleplaying game **Rats with Gats** (where players roleplay as gunslinging pirate rats, or "Pi-Rats", in the magical land of Yeld). The application manages lobbies, character creation, card mechanics, scene phases, obstacles, challenges, and player voting. See [RULEBOOK.md](RULEBOOK.md) for the game rules.
It is built with a **FastAPI** + **SQLModel** (SQLite) backend and a **Svelte 5** single-page frontend (in `frontend/`), which polls the backend's JSON state endpoint for near-real-time updates.
---
## Features
- **Game Lobby:** Create games and join as players via a unique game ID.
- **Character Creation:**
- Fill out the character profile (appearance, smell, catchphrase).
- Delegate custom "Like/Hate" relationship questionnaire cards to other crewmates (answering them for each other!).
- Draft three "Secret Pirate Techniques" which are automatically shuffled and swapped among players.
- Bind swapped techniques to Face Cards (Jack, Queen, King) for play.
- **Dynamic Card Mechanics:**
- Automated 54-card deck shuffling and card drawing.
- Automatically matches card suits to thematic obstacles (Clubs for combat, Spades for stealth/cunning, Hearts for social/morale, Diamonds for nautical/athletics).
- **Scene Management:**
- Assign roles (Pi-Rats or "The Deep" narrator).
- Dynamic challenge creation linking multiple active obstacles.
- Automatically handles card matching colors/values, automatic success when playing Face Card techniques, and Joker card triggers to discard/replace obstacles.
- **Between-Scenes Voting:**
- Vote on crewmates to rank up.
- Toggle personal objectives (Get a Gat, Earn a Name, Die like a Pirate).

## Installation & Running
This project supports standard Python package tools as well as Nix flakes.
### Option 1: Standard Python Installation
#### Prerequisites
- Python >= 3.9
- Virtual environment tool (optional but recommended)
#### 1. Setup Virtual Environment (Optional)
```bash
python -m venv .venv
source .venv/bin/activate
```
#### 2. Install Package
Install the package and its dependencies in editable mode:
```bash
pip install -e .
```
#### 3. Run the App
Launch the FastAPI server using the installed package entrypoint:
```bash
pirats --host 0.0.0.0 --port 8000 --reload
```
Alternatively, run it with `uvicorn`:
```bash
uvicorn pirats.main:app --host 0.0.0.0 --port 8000 --reload
```
Once running, access the web UI at [http://localhost:8000](http://localhost:8000).
---
### Option 2: Using Nix Flakes
If you use the Nix package manager, this repository provides a complete environment.
#### 1. Enter the Development Shell
Includes Python, all runtime dependencies, and testing tools (`pytest`):
```bash
nix develop
```
#### 2. Run the Application
Run the package directly from the flake:
```bash
nix run . -- --host 0.0.0.0 --port 8000
```
#### 3. Build the Application Package
```bash
nix build .
```
The executable will be located in `./result/bin/pirats`.

## Deploying as a NixOS Service
The Nix flake exposes a NixOS module that configures the application to run as a systemd service with appropriate sandboxing.
Add this flake to your system configuration and configure the service:
```nix
services.pirats = {
enable = true;
host = "127.0.0.1";
port = 8000;
databasePath = "/var/lib/pirats/rats_with_gats.db";
openFirewall = false; # Set to true to open ports in the firewall
};
```
---
## Running Tests
Tests are written using `pytest`.
### Running with Pip
```bash
pytest
```
### Running with Nix
```bash
nix develop --command pytest
```

### Frontend Development
Run the backend (`pirats --reload`) and the Vite dev server side by side; Vite proxies `/api` to port 8000:
```bash
cd frontend && npm install && npm run dev
```
