Installation

Quick Start

from datetime import datetime
from calendar_link import CalendarEvent, CalendarGenerator

# Create an event
event = CalendarEvent(
    title="Team Meeting",
    start_time=datetime(2024, 1, 15, 10, 0),  # 10:00 AM
    end_time=datetime(2024, 1, 15, 11, 0),    # 11:00 AM
    description="Weekly team sync meeting",
    location="Conference Room A",
    attendees=["[e-mail]", "[e-mail]"]
)

# Generate calendar links
generator = CalendarGenerator()

# Generate Google Calendar link
google_link = generator.generate_link(event, "google")
print(f"Google Calendar: {google_link}")

# Generate ICS file content
ics_content = generator.generate_ics(event)
print(f"ICS Content:\n{ics_content}")

# Generate all links at once
all_links = generator.generate_all_links(event)
for service, link in all_links.items():
    print(f"{service}: {link}")

Usage Examples

Creating Events from Dictionary

from calendar_link import CalendarEvent

event_data = {
    "title": "Birthday Party",
    "start_time": "2024-02-15T18:00:00",
    "end_time": "2024-02-15T22:00:00",
    "description": "Come celebrate!",
    "location": "My House",
    "all_day": False
}

event = CalendarEvent.from_dict(event_data)

Working with Timezones

import pytz
from datetime import datetime
from calendar_link import CalendarEvent

# Create event with specific timezone
ny_tz = pytz.timezone("America/New_York")
start_time = ny_tz.localize(datetime(2024, 1, 15, 10, 0))

event = CalendarEvent(
    title="Meeting",
    start_time=start_time,
    end_time=start_time.replace(hour=11),
    timezone="America/New_York"
)

All-Day Events

from datetime import datetime
from calendar_link import CalendarEvent

event = CalendarEvent(
    title="Vacation Day",
    start_time=datetime(2024, 1, 15, 0, 0),
    end_time=datetime(2024, 1, 15, 0, 0),
    all_day=True
)

Saving ICS File

from calendar_link import CalendarEvent, CalendarGenerator

event = CalendarEvent(
    title="Important Meeting",
    start_time=datetime(2024, 1, 15, 14, 30),
    end_time=datetime(2024, 1, 15, 15, 30),
    description="Don't forget to prepare the presentation"
)

generator = CalendarGenerator()
ics_content = generator.generate_ics(event)

# Save to file
with open("meeting.ics", "w") as f:
    f.write(ics_content)

API Reference

CalendarEvent

The main class for representing calendar events.

    all_day: bool = False,
    timezone: Optional[str] = None
)

• to_dict() -> dict: Convert event to dictionary
• get_duration_minutes() -> int: Get event duration in minutes
• is_same_day() -> bool: Check if start and end are on same day

CalendarGenerator

The main class for generating calendar links and ICS files.

Methods

• generate_link(event: CalendarEvent, service: str) -> str: Generate link for specific service
• generate_ics(event: CalendarEvent) -> str: Generate ICS file content
• generate_all_links(event: CalendarEvent) -> Dict[str, str]: Generate all links
• get_supported_services() -> Dict[str, str]: Get list of supported services

Error Handling

The package includes custom exceptions for better error handling:

from calendar_link import CalendarLinkError, InvalidEventDataError, UnsupportedCalendarServiceError

try:
    event = CalendarEvent(title="", start_time=datetime.now())  # Invalid title
except InvalidEventDataError as e:
    print(f"Invalid event data: {e}")

try:
    generator.generate_link(event, "unsupported_service")
except UnsupportedCalendarServiceError as e:
    print(f"Unsupported service: {e}")

Utility Functions

The package also includes utility functions for common operations:

from calendar_link.utils import parse_datetime, validate_email, sanitize_text

# Parse datetime with timezone
dt = parse_datetime("2024-01-15 10:00:00", "America/New_York")

# Validate email
is_valid = validate_email("[e-mail]")
