##Warning: This version of GCal4Ruby uses only undocumented OAuth authentication, and an unofficial version of GData4Ruby.

##Introduction GCal4Ruby is a full featured wrapper for the google calendar API. GCal4Ruby implements all of the functionality available through the Google Calnedar API, including permissions, attendees, reminders and event recurrence.

###Website http://cookingandcoding.com/gcal4ruby/

##Description GCal4Ruby has three major components: the service, calendar and event objects. Each service has many calendars, which in turn have many events. Each service is the representation of a google account, and thus must be successfully authenticated using valid Google Calendar account credentials.

##Examples Below are some common usage examples. For more examples, check the documentation. ###Service

1. Authenticate using client login (currently disabled) service # Service.new service.authenticate({ :username => "[email protected]", :password => "password" })

2. Authenticate using OAuth require 'oauth' consumer = OAuth::Consumer.new(auth[:consumer_key], auth[:consumer_secret], {:site => 'https://wwww.google.com'}) access_token = OAuth::AccessToken.new(consumer, auth[:token], auth[:secret])

   service = Service.new service.authenticate({ :access_token => access_token })

3. Get Calendar List calendars # service.calendars

###Calendar All usages assume a successfully authenticated Service.

1. Create a new Calendar cal = Calendar.new(service)

2. Find a calendar by ID cal = Calendar.find(service, {:id => cal_id})

3. Get all calendar events cal = Calendar.find(service, {:id => cal_id}) events = cal.events

4. Find an existing calendar by title cal = Calendar.find(service, {:title => "New Calendar"})

5. Find all calendars containing a search term cal = Calendar.find(service, "Soccer Team") ###Event All usages assume a successfully authenticated Service and valid Calendar.

6. Create a new Event event = Event.new(service, {:calendar => cal, :title => "Soccer Game", :start => Time.parse("12-06-2009 at 12:30 PM"), :end => Time.parse("12-06-2009 at 1:30 PM"), :where => "Merry Playfields"}) event.save

7. Find an existing Event by title event = Event.find(service, {:title => "Soccer Game"})

8. Find an existing Event by ID event = Event.find(service, {:id => event.id})

9. Find all events containing the search term event = Event.find(service, "Soccer Game")

10. Find all events on a calendar containing the search term event = Event.find(service, "Soccer Game", {:calendar => cal.id})

11. Find events within a date range event = Event.find(service, "Soccer Game", {'start-min' => Time.parse("01/01/2010").utc.xmlschema, 'start-max' => Time.parse("06/01/2010").utc.xmlschema})

12. Create a recurring event for every saturday event = Event.new(service) event.title = "Baseball Game" event.calendar = cal event.where = "Municipal Stadium" event.recurrence = Recurrence.new event.recurrence.start_time = Time.parse("06/20/2009 at 4:30 PM") event.recurrence.end_time = Time.parse("06/20/2009 at 6:30 PM") event.recurrence.frequency = {"weekly" => ["SA"]} event.save

13. Create an event with a 15 minute email reminder event = Event.new(service) event.calendar = cal event.title = "Dinner with Kate" event.start_time = Time.parse("06/20/2009 at 5 pm") event.end_time = Time.parse("06/20/2009 at 8 pm") event.where = "Luigi's" event.reminder = {:minutes => 15, :method => 'email'} event.save

14. Create an event with attendees event = Event.new(service) event.calendar = cal event.title = "Dinner with Kate" event.start_time = Time.parse("06/20/2009 at 5 pm") event.end_time = Time.parse("06/20/2009 at 8 pm") event.attendees => {:name => "Kate", :email => "[email protected]"} event.save

Errata and Bugs you should know about

Currently, an event's 'edited' time attribute returns nil. instead use 'updated'
