Setup

1. Install dependencies:

pip install -r requirements.txt

2. Run the application:

python app.py

3. Visit http://127.0.0.1:3000 in your browser

Environment Variables

The app can be configured via environment variables:

• SECRET_KEY - Flask secret key (defaults to 'your-secret-key')
• PORT - Port to run on (defaults to 3000)
• DEBUG - Enable debug mode (defaults to False)

Development:

export DEBUG=True
python app.py

Production:

export SECRET_KEY="your-secure-random-secret-key"
export PORT=3000
python app.py

Adding Comics

Comics are stored in the COMICS list in comics_data.py. Each comic entry:

{
    'number': 1,                           # Comic number (required, sequential)
    'filename': 'comic-001.png',           # Image filename (required)
    'date': '2025-01-01',                  # Publication date (required)
    'alt_text': 'Alt text for comic',      # Accessibility text (required)
    'title': 'Comic Title',                # Title (optional, shows #X if absent)
    'author_note': 'Optional note'         # Author note (optional)
}

Adding a New Comic

Option 1: Use the script (recommended)

python scripts/add_comic.py

This will automatically add a new entry with defaults. Then edit comics_data.py to customize.

Option 2: Manual

1. Save your comic image in static/images/ (e.g., comic-001.png)
2. Optionally, create a thumbnail in static/images/thumbs/ with the same filename
3. Add the comic entry to the COMICS list in comics_data.py

Generating RSS Feed

After adding comics, regenerate the RSS feed:

python scripts/generate_rss.py

This creates/updates static/feed.rss

Production Deployment

For production, you should NOT use Flask's built-in development server. Instead:

1. Generate a Secure Secret Key

python -c "import secrets; print(secrets.token_hex(32))"

2. Set Environment Variables

export SECRET_KEY="generated-secret-key-from-above"
export DEBUG=False
export PORT=3000

3. Use a Production WSGI Server

Install Gunicorn:

pip install gunicorn

Run with Gunicorn:

gunicorn app:app --bind 0.0.0.0:3000 --workers 4

4. Use a Reverse Proxy (Recommended)

Set up Nginx or another reverse proxy in front of Gunicorn for:

• HTTPS/SSL termination
• Static file serving
• Load balancing
• Better security

5. Additional Production Considerations

• Use a process manager (systemd, supervisor)
• Set appropriate file permissions
• Enable HTTPS with Let's Encrypt
• Consider using a CDN for static assets
• Monitor logs and performance
• Set up automated backups of comics_data.py

Upgrading to a Database

For larger comic archives, consider replacing the COMICS list with a database:

• SQLite for simple setups
• PostgreSQL/MySQL for production
• Use Flask-SQLAlchemy for ORM support

Customization

Branding

• Update "Sunday Comics" references in templates/base.html
• Update site title and footer text

Styling

• Modify static/css/style.css to change colors, fonts, and layout
• Current color scheme uses blue (#3498db) and dark blue-gray (#2c3e50)

About Page

• Edit templates/about.html to add your bio and comic information

Pages

• / - Shows the latest comic
• /comic/<id> - View a specific comic by number
• /archive - Browse all comics in a grid
• /about - About the comic and author
• /static/feed.rss - RSS feed
