A Python library for processing events and generating ICS calendar files from various data sources.

## ✨ Features

- **Event Processing**: Normalize events from any source with customizable field mappings
- **Date/Time Parsing**: Handles various date and time formats
- **Event Validation**: Data quality validation before calendar generation
- **Statistics & Analytics**: Event data insights and reporting
- **Error Handling**: Detailed error reporting for invalid data
- **ICS Generation**: RFC 5545 compliant ICS calendar files
- **Modern Python**: Built with Python 3.11+ type hints

## 💎 Installation

```bash
pip install ics-calendar-utils
```

## 🚀 Usage

### Basic Usage

```python
from ics_calendar_utils import create_calendar

# Your event data from any source
events = [
    {
        'title': 'Team Meeting',
        'date': '2024-12-20',
        'time': '14:00',
        'location': 'Conference Room A',
        'description': 'Weekly team sync'
    },
    {
        'title': 'Project Deadline',
        'date': 'Dec 25, 2024',
        'location': 'Online'
    }
]

# Simple field mapping
field_mapping = {
    'title': 'summary',
    'date': 'dtstart_date',
    'time': 'dtstart_time'
}

# Generate ICS calendar
ics_content = create_calendar(
    events,
    calendar_name="My Calendar",
    filename="my_events.ics",
    field_mapping=field_mapping
)

print("Calendar generated successfully!")
```

## ⚙️ Configuration

### Advanced Usage

For more control over processing and detailed results:

```python
from ics_calendar_utils import process_and_generate

# Events with custom field names
events = [
    {
        'event_name': 'Rugby Match: England vs Wales',
        'event_date': '2024-12-21',
        'kickoff_time': '15:00',
        'venue': 'Twickenham Stadium',
        'competition': 'Six Nations',
        'ticket_url': 'https://example.com/tickets'
    }
]

# Custom field mapping
field_mapping = {
    'event_name': 'summary',
    'event_date': 'dtstart_date',
    'kickoff_time': 'dtstart_time',
    'venue': 'location',
    'competition': 'categories',
    'ticket_url': 'url'
}

# Process with detailed results
result = process_and_generate(
    events,
    calendar_name="Rugby Fixtures",
    output_file="rugby_calendar.ics",
    field_mapping=field_mapping,
    validate=True
)

# Access detailed information
print(f"Processed {result['stats']['total_events']} events")
print(f"Events with times: {result['stats']['events_with_time']}")
print(f"Date range: {result['stats']['date_range']['earliest']} to {result['stats']['date_range']['latest']}")

if result['processing_errors']:
    print("Processing errors:", result['processing_errors'])
```

### Low-Level API

For maximum control:

```python
from ics_calendar_utils import EventProcessor, ICSGenerator

# Initialize components
processor = EventProcessor()
processor.add_mapping({
    'event_title': 'summary',
    'start_date': 'dtstart_date'
})

generator = ICSGenerator(calendar_name="Custom Calendar")

# Process events
processed_events = processor.process_events(raw_events)

# Validate before generation
validation_errors = generator.validate_events(processed_events)
if validation_errors:
    print("Validation issues:", validation_errors)

# Generate ICS
ics_content = generator.generate_ics(processed_events)
```

## 🎯 Supported Date/Time Formats

The library parses various date and time formats:

### Date Formats

- ISO format: `2024-12-20`
- US format: `Dec 20, 2024` or `December 20, 2024`
- European format: `20/12/2024` or `20 December 2024`
- Various separators: dots, slashes, spaces, hyphens

### Time Formats

- 24-hour: `14:30`, `09:00`
- 12-hour: `2:30pm`, `9am`, `noon`
- Multiple times: `14:30 & 16:45`
- Flexible separators and spacing

## 🧪 Error Handling

The library provides error handling:

```python
result = process_and_generate(events, validate=True)

# Check for issues
if result['processing_errors']:
    print("Data processing issues:")
    for error in result['processing_errors']:
        print(f"  - {error}")

if result['validation_errors']:
    print("Validation issues:")
    for error in result['validation_errors']:
        print(f"  - {error}")
```
