See the iCalendar spec (RFC 2445) for - * the specification of the recurrence rules and lots of examples - * (sections 4.3.10 & 4.8.5). We also want to support the older - * vCalendar spec, though this should be easy since it is basically a - * subset of iCalendar. - * - * o An iCalendar event can have any number of recurrence rules specifying - * occurrences of the event, as well as dates & times of specific - * occurrences. It can also have any number of recurrence rules and - * specific dates & times specifying exceptions to the occurrences. - * So we first merge all the occurrences generated, eliminating any - * duplicates, then we generate all the exceptions and remove these to - * form the final set of occurrences. - * - * o There are 7 frequencies of occurrences: YEARLY, MONTHLY, WEEKLY, DAILY, - * HOURLY, MINUTELY & SECONDLY. The 'interval' property specifies the - * multiples of the frequency which we step by. We generate a 'set' of - * occurrences for each period defined by the frequency & interval. - * So for a YEARLY frequency with an interval of 3, we generate a set of - * occurrences for every 3rd year. We use complete years here - any - * generated occurrences that occur before the event's start (or after its - * end) are just discarded. - * - * o There are 8 frequency modifiers: BYMONTH, BYWEEKNO, BYYEARDAY, BYMONTHDAY, - * BYDAY, BYHOUR, BYMINUTE & BYSECOND. These can either add extra occurrences - * or filter out occurrences. For example 'FREQ=YEARLY;BYMONTH=1,2' produces - * 2 occurrences for each year rather than the default 1. And - * 'FREQ=DAILY;BYMONTH=1' filters out all occurrences except those in Jan. - * If the modifier works on periods which are less than the recurrence - * frequency, then extra occurrences are added, otherwise occurrences are - * filtered. So we have 2 functions for each modifier - one to expand events - * and the other to filter. We use a table of functions for each frequency - * which points to the appropriate function to use for each modifier. - * - * o Any number of frequency modifiers can be used in a recurrence rule. - * (Though the iCalendar spec says that BYWEEKNO can only be used in a YEARLY - * rule, and some modifiers aren't appropriate for some frequencies - e.g. - * BYMONTHDAY is not really useful in a WEEKLY frequency, and BYYEARDAY is - * not useful in a MONTHLY or WEEKLY frequency). - * The frequency modifiers are applied in the order given above. The first 5 - * modifier rules (BYMONTH, BYWEEKNO, BYYEARDAY, BYMONTHDAY & BYDAY) all - * produce the days on which the occurrences take place, and so we have to - * compute some of these in parallel rather than sequentially, or we may end - * up with too many days. - * - * o Note that some expansion functions may produce days which are invalid, - * e.g. 31st September, 30th Feb. These invalid days are removed before the - * BYHOUR, BYMINUTE & BYSECOND modifier functions are applied. - * - * o After the set of occurrences for the frequency interval are generated, - * the BYSETPOS property is used to select which of the occurrences are - * finally output. If BYSETPOS is not specified then all the occurrences are - * output. - */ - -/* Define this for some debugging output. */ -#if 0 -#define CAL_OBJ_DEBUG 1 -#endif - -/* We will use icalrecurrencetype instead of this eventually. */ -typedef struct { - icalrecurrencetype_frequency freq; - - int interval; - - /* Specifies the end of the recurrence.
