## Quick Start

### 1. Install Dependencies

```bash
# Clone the repository
git clone <repository-url>
cd imdb_watchlist_to_sonarr

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt
```

### 2. Configure Your Settings

```bash
# Copy the example configuration
cp .env.example .env

# Edit with your actual values
nano .env  # or vim, code, etc.
```

Required settings in `.env`:
```bash
SONARR_URL=http://localhost:8989
SONARR_API_KEY=your_sonarr_api_key_here
IMDB_WATCHLIST_URL=https://www.imdb.com/user/urXXXXXXX/watchlist/
```

### 3. Run the Script

```bash
# Test without making changes (recommended first run)
python3 imdb_watchlist_to_sonarr.py --dry-run

# Or use make for convenience
make dry-run

# When ready, run for real
make run
```

## Usage

### Basic Commands

```bash
# Dry run (safe, no changes made)
make dry-run

# Live run (adds shows to Sonarr)
make run

# Show version
make version

# Show all available commands
make help
```

### Advanced Options

```bash
# Process only first 3 pages (for testing)
python3 imdb_watchlist_to_sonarr.py --dry-run --max-pages 3

# Verbose logging
python3 imdb_watchlist_to_sonarr.py --dry-run --verbose

# Override quality profile
python3 imdb_watchlist_to_sonarr.py --quality-profile "Ultra-HD" --dry-run

# All options
python3 imdb_watchlist_to_sonarr.py --help
```

## Configuration

### .env File (Recommended)

All settings can be configured in `.env`:

```bash
# Sonarr Configuration
SONARR_URL=http://localhost:8989
SONARR_API_KEY=your_api_key
SONARR_ROOT_FOLDER=/Volumes/public/Television
SONARR_QUALITY_PROFILE=HD-1080p
SONARR_MONITOR=all

# IMDb Configuration
IMDB_WATCHLIST_URL=https://www.imdb.com/user/urXXXXXXX/watchlist/

# Script Behavior
DRY_RUN=false
```

See [CONFIGURATION.md](CONFIGURATION.md) for complete documentation.

### Getting Your Configuration Values

**Sonarr API Key:**
1. Open Sonarr → Settings → General → Security
2. Copy the API Key

**IMDb Watchlist URL:**
1. Go to IMDb → Your Watchlist
2. Copy the URL from your browser
3. Format: `https://www.imdb.com/user/urXXXXXXX/watchlist/`

## Development

### Setup Development Environment

```bash
# Install development dependencies
make install-dev

# Run all quality checks
make check-all

# Format code
make format

# Run tests
make test
```

### Code Quality

This project maintains high code quality standards:

- **Linting**: ruff (0 errors)
- **Formatting**: black (100-char lines)
- **Type Checking**: mypy (strict mode)
- **Security**: bandit scanning
- **Testing**: pytest with coverage

Run all checks:
```bash
make check-all
```

## Architecture

### Data Flow

1. **Fetch IMDb Watchlist** → Parse JSON from __NEXT_DATA__ block
2. **Filter TV Shows** → Extract tvSeries, tvMiniSeries, tvMovie
3. **Paginate** → Process all pages (250 items each)
4. **Check Sonarr** → Skip shows already in library
5. **Lookup in Sonarr** → Direct IMDb ID lookup (no TVMaze needed)
6. **Add to Sonarr** → With quality profile and monitoring settings

### Performance

- **Connection Pooling**: Reuses HTTP connections for efficiency
- **Exponential Backoff**: Smart retry strategy (1s → 10s)
- **Batch Processing**: Processes 50 shows at a time with progress indicators
- **Optimized Lookups**: Direct Sonarr IMDb lookups (~40% faster than TVMaze)

## Security

This project follows security best practices:

- ✅ API keys stored in `.env` file (not in code)
- ✅ `.env` in `.gitignore` (never committed to git)
- ✅ Input validation for URLs and API keys
- ✅ No secrets in shell history or process lists
- ✅ Security scanning with bandit (0 issues)
- ✅ Optional system keyring support

See [CONFIGURATION.md](CONFIGURATION.md) for security best practices.

## Requirements

- Python 3.9+
- Sonarr v3+ with API access
- IMDb watchlist (public or private with cookie)

### Dependencies

- `requests` - HTTP library
- `python-dotenv` - Environment variable management

### Development Dependencies

- `ruff` - Fast Python linter
- `black` - Code formatter
- `mypy` - Static type checker
- `bandit` - Security scanner
- `pytest` - Testing framework

## Troubleshooting

### Script can't find .env file
Make sure `.env` is in the project root directory (same directory as the script).

### API key validation fails
Ensure your Sonarr API key is at least 10 characters and correct.

### No shows found
- Verify your IMDb watchlist URL is correct
- Check that you have TV shows (not just movies) in your watchlist
- For private watchlists, add `IMDB_COOKIE` to .env

### Shows not being added
- Check Sonarr logs for errors
- Verify quality profile name matches exactly (case-sensitive)
- Ensure root folder path exists and is writable

For more help, see [CONFIGURATION.md](CONFIGURATION.md).

## Contributing

Contributions welcome! Please ensure:

1. All tests pass: `make check-all`
2. Code is formatted: `make format`
3. Type hints are complete: `make type-check`
4. Security scan passes: `make security-check`
