PyraPuzzle - A Daily Puzzle Game Built with Pyramid
=========================================================

**PyraPuzzle** is a **public domain** web application built on the `Pyramid <https://trypyramid.com>`_ framework. It offers daily puzzles for users to enjoy and compete on leaderboards. The application supports guest users, registered users, and administrative functions for managing puzzles and users.

Key Features
============

- **Daily Puzzles**: Fresh puzzles every day in various sizes (3x3, 4x4, 5x5).
- **Guest and Registered Users**: Play as a guest or register to track your progress.
- **Passwordless Authentication**: Secure login via email verification codes (OTP).
- **Leaderboards**: Compete with others on daily leaderboards and global rankings.
- **User Profiles**: Customize your profile and view statistics.
- **Admin Tools**: Upload puzzles, manage users, and monitor the application.
- **Persistent Data**: Application data and secrets are stored in a mounted `data/` directory.

Git Repository
==============

The project is maintained at:

- `PyraPuzzle Git Repo <https://git.unturf.com/engineering/unturf/puzzle.unturf.com>`_

Since this project is in the public domain, you can adapt and redistribute it freely.

Configuration via Environment
=============================

PyraPuzzle fetches settings from environment variables with sensible defaults:

- ``PYRAPUZZLE_SECRET``  
  The secret key for session signing.  
  If missing, PyraPuzzle automatically generates a **random 64-character** string at runtime, saves it to ``data/secret.txt``, which will log out all users if changed.

- ``PYRAPUZZLE_DB_URL``  
  Connection string for the database. Default: ``sqlite:///data/puzzle_game.db``.

- ``PYRAPUZZLE_HOST`` and ``PYRAPUZZLE_PORT``  
  The host and port to serve on. Defaults: ``0.0.0.0`` (host), ``6543`` (port).

- ``PYRAPUZZLE_SMTP_HOST`` and ``PYRAPUZZLE_SMTP_PORT``  
  SMTP server details for sending emails. Defaults: ``localhost:25``.

Local Setup
===========

1. **Clone the Project**

   .. code-block:: bash

      git clone https://git.unturf.com/engineering/unturf/puzzle.unturf.com.git
      cd puzzle.unturf.com

2. **Create a Virtual Environment**

   .. code-block:: bash

      python3 -m venv venv
      source venv/bin/activate  # On Linux/Mac
      # On Windows:
      venv\Scripts\activate.bat

3. **Install Dependencies**

   .. code-block:: bash

      pip install -r requirements.txt

4. **Run the Application**

   .. code-block:: bash

      # Optionally set PYRAPUZZLE_SECRET to a fixed value
      export PYRAPUZZLE_SECRET="YOUR_OWN_LONG_RANDOM_STRING"
      python app.py

   If ``PYRAPUZZLE_SECRET`` is **not** set, the app automatically generates a 64-character secret at runtime and saves it to ``data/secret.txt``.

5. **Access the Application**

   Open your browser and navigate to `http://localhost:6543` or `http://<HOST>:<PORT>` based on your environment variables.

Docker Deployment
=================

A Dockerfile is provided to facilitate containerized deployment. Below is an example Dockerfile that:

- Uses **Waitress** to run PyraPuzzle.
- Defines a **volume** for the `data/` directory to persist application data.

.. code-block:: dockerfile

   # Dockerfile for PyraPuzzle

   FROM python:3.9-slim

   WORKDIR /app

   # Copy application code
   COPY . /app

   # Install Python dependencies
   RUN pip install --no-cache-dir -r requirements.txt

   # Expose the application port
   EXPOSE 6543

   # Ensure the data directory exists and is mounted as a volume
   VOLUME /app/data

   # Set environment variables (override these in production)
   ENV PYRAPUZZLE_HOST="0.0.0.0"
   ENV PYRAPUZZLE_PORT="6543"
   ENV PYRAPUZZLE_DB_URL="sqlite:///data/puzzle_game.db"
   ENV PYRAPUZZLE_SMTP_HOST="localhost"
   ENV PYRAPUZZLE_SMTP_PORT="25"

   # Start the application
   CMD ["python", "app.py"]

**Notes:**

- **Data Persistence**: The `data/` directory is where the database and secret files are stored. Mount this directory as a volume to persist data between container restarts.

- **Secrets**: In production, set `PYRAPUZZLE_SECRET` to a fixed value to avoid invalidating user sessions.

**Building and Running with Docker:**

.. code-block:: bash

   # Build the Docker image
   docker build -t pyrapuzzle .

   # Run the Docker container
   docker run -d -p 6543:6543 \
      -v $(pwd)/data:/app/data \
      --name pyrapuzzle \
      pyrapuzzle

   # For Windows PowerShell, use:
   docker run -d -p 6543:6543 `
      -v ${PWD}/data:/app/data `
      --name pyrapuzzle `
      pyrapuzzle

**Environment Variables in Docker:**

You can pass environment variables to the Docker container using the `-e` flag:

.. code-block:: bash

   docker run -d -p 6543:6543 \
      -v $(pwd)/data:/app/data \
      -e PYRAPUZZLE_SECRET="YOUR_OWN_LONG_RANDOM_STRING" \
      -e PYRAPUZZLE_SMTP_HOST="smtp.example.com" \
      -e PYRAPUZZLE_SMTP_PORT="587" \
      --name pyrapuzzle \
      pyrapuzzle
