Installation

pip install c3voc-schedule-tools

Quick Start

Basic Schedule Creation

from voc import Schedule, Event, Room

# Create a new schedule
schedule = Schedule.from_template(
    name="My Conference 2024",
    conference_title="My Conference",
    conference_acronym="MC24",
    start_day=25,
    days_count=3,
    timezone="Europe/Berlin"
)

# Add rooms, generate your own global unique ids e.g. via `uuidgen`
schedule.add_rooms([
    {"name": "Main Hall", "guid": "67D04C40-B35A-496A-A31C-C0F3FF63DAB7"},
    {"name": "Workshop Room", "guid": "5564FBA9-DBB5-4B6B-A0F0-CCF6C9F1EBD7"}
])

# Add an event
event = Event({
    "id": "event-1",
    "title": "Opening Keynote",
    "abstract": "Welcome to the conference",
    "date": "2024-12-25T10:00:00+01:00",
    "duration": "01:00",
    "room": "Main Hall",
    "track": "Keynotes",
    "type": "lecture",
    "language": "en",
    "persons": [{"public_name": "Jane Doe"}]
})
schedule.add_event(event)

# Export to JSON
schedule.export('schedule.json')

Loading from Pretalx

from voc import PretalxConference, Schedule

# Load conference data from pretalx
conference = PretalxConference(
    url="https://pretalx.example.com/event/my-conference/",
    data={"name": "My Conference"}
)

# Get the schedule
schedule = conference.schedule()

# Export to different formats
schedule.export('schedule.json')
schedule.export('schedule.xml')

Working with Existing Schedules

from voc import Schedule

# Load from URL
schedule = Schedule.from_url("https://example.com/schedule.json")

# Load from file
schedule = Schedule.from_file("schedule.json")

# Filter events by track
track_events = schedule.events(filter=lambda e: e.get('track') == 'Security')

# Get all rooms
rooms = schedule.rooms()

# Get events for a specific day
day_1_events = schedule.day(1).events()
