# CalInvite::Providers::Ics

Generic ICS provider for generating standard iCalendar (.ics) files.
This provider generates ICS files that are compatible with most calendar applications.
Supports all-day events, regular events, and multi-day sessions with proper timezone handling.

This is the single RFC 5545 generator for the gem: {Ical} and {IcsContent}
are subclasses kept for their public names and produce identical output.

@example Creating a regular event ICS file
  event = CalInvite::Event.new(
    title: "Team Meeting",
    start_time: Time.now,
    end_time: Time.now + 3600,
    timezone: 'America/New_York'
  )
  ics = CalInvite::Providers::Ics.new(event)
  ics_content = ics.generate

@example Creating an all-day event ICS file
  event = CalInvite::Event.new(
    title: "Company Holiday",
    all_day: true,
    start_time: Date.today,
    end_time: Date.today + 1
  )
  ics_content = CalInvite::Providers::Ics.new(event).generate

@example Creating a multi-day event ICS file
  event = CalInvite::Event.new(
    title: "Conference",
    multi_day_sessions: [
      { start_time: Time.parse("2024-04-01 09:00"), end_time: Time.parse("2024-04-01 17:00") },
      { start_time: Time.parse("2024-04-02 09:00"), end_time: Time.parse("2024-04-02 17:00") }
    ]
  )
  ics_content = CalInvite::Providers::Ics.new(event).generate
