**QuickMUD is a modern Python port of the legendary ROM 2.4b6 MUD engine**, derived from ROM 2.4b6, Merc 2.1 and DikuMUD. This is a complete rewrite that brings the classic text-based MMORPG experience to modern Python with async networking, JSON world data, and **100% ROM 2.4b behavioral parity**.

## 🎮 What is a MUD?

A "[Multi-User Dungeon](https://en.wikipedia.org/wiki/MUD)" (MUD) is a text-based MMORPG that runs over telnet. ROM is renowned for its fast-paced combat system and rich player interaction. ROM was also the foundation for [Carrion Fields](http://www.carrionfields.net/), one of the most acclaimed MUDs ever created.

## ✨ Key Features

- **🎯 100% ROM 2.4b Behavioral Parity CERTIFIED**: Official certification with comprehensive audits ([see certification](ROM_2.4B6_PARITY_CERTIFICATION.md))
- **🚀 Modern Python Architecture**: Fully async/await networking with SQLAlchemy ORM
- **📡 Multiple Connection Options**: Telnet, WebSocket, and SSH server support
- **🗺️ JSON World Loading**: Easy-to-edit world data with 352+ room resets
- **🏪 Complete Shop System**: Buy, sell, and list items with working economy
- **⚔️ ROM Combat System**: Classic ROM combat mechanics and skill system
- **👥 Social Features**: Say, tell, shout, and 100+ social interactions
- **🛠️ Admin Commands**: Teleport, spawn, ban management, and OLC building
- **📊 Comprehensive Testing**: 1435+ tests with 688/701 integration tests passing (98.1%)
- **🔧 ROM C-Compatible API**: Public API wrappers for external tools and scripts (27 functions)

## 📦 Installation

### For Players & Server Operators

```bash
pip install quickmud
```

### Quick Start

Run a QuickMUD server:

**Telnet Server (port 5001):**
```bash
python3 -m mud socketserver
# or
mud socketserver
```

> **⚠️ macOS Users:** Port 5000 is used by macOS AirPlay Receiver (Monterey+). QuickMUD defaults to port 5001 to avoid conflicts. To use a different port: `python3 -m mud socketserver --port 4000`

**WebSocket Server (port 8000):**
```bash
python3 -m mud websocketserver
# or
mud websocketserver
```

**SSH Server (port 2222):**
```bash
python3 -m mud sshserver
# or
mud sshserver
```

All servers provide:
- ✓ Game tick running at 4 Hz
- ✓ Time advancement
- ✓ Mob AI active

Connect to the server:

**Via Telnet:**
```bash
telnet localhost 5001
```

**Via SSH:**
```bash
ssh -p 2222 player@localhost
# Note: SSH username/password are ignored; MUD authentication happens after connection
```

For a fully reproducible environment, use the pinned requirements files generated with [pip-tools](https://github.com/jazzband/pip-tools):

```bash
pip install -r requirements-dev.txt
```

To update the pinned dependencies:

```bash
pip-compile requirements.in
pip-compile requirements-dev.in
```

Tools like [Poetry](https://python-poetry.org/) provide a similar workflow if you prefer that approach.

Run tests with:

```bash
pytest
```

### Publishing

To release a new version to PyPI:

1. Update the version in `pyproject.toml`.
2. Commit and tag:

```bash
git commit -am "release: v1.2.3"
git tag v1.2.3
git push origin main --tags
```

The GitHub Actions workflow will build and publish the package when the tag is pushed.

## Python Architecture

Game systems are implemented in Python modules:

- `mud/net` provides asynchronous telnet and websocket servers.
- `mud/game_loop.py` drives the tick-based update loop.
- `mud/commands` contains the command dispatcher and handlers.
- `mud/combat` and `mud/skills` implement combat and abilities.
- `mud/persistence.py` handles saving characters and world state.

Start the server with:

```sh
python -m mud runserver
```

## Docker Image

Build and run the Python server with Docker:

```bash
docker build -t quickmud .
docker run -p 5001:5001 quickmud
```

Or use docker-compose to rebuild on changes and mount the repository:

```bash
docker-compose up
```

Connect via:

```bash
telnet localhost 5001
```

## Data Models

The `mud/models` package defines dataclasses used by the game engine.
They mirror the JSON schemas in `schemas/` and supply enums and registries
for loading and manipulating area, room, object, and character data.

### 📚 For Contributors

See [ROM_PARITY_FEATURE_TRACKER.md](docs/parity/ROM_PARITY_FEATURE_TRACKER.md) for detailed feature status and [AGENTS.md](AGENTS.md) for AI-assisted development workflows.

**Development Guidelines**:

1. **ROM Parity First**: Reference original ROM 2.4 C sources in `src/` for canonical behavior
2. **Test Coverage**: Add tests in `tests/` with golden files derived from ROM behavior  
3. **Backward Compatibility**: Don't break existing save files or area data
4. **Documentation**: Update relevant docs and inline code documentation
5. **Performance**: Consider impact on the main game loop and player experience
