Added this routine so Monthly recurrences use the weekday field as a
1999-04-01 Steve Murphy <murf@e-tools.com> * calobj.c (weekdaynum): Added this routine so Monthly recurrences use the weekday field as a simple integer for a single weekday. * calobj.c (load_recur_monthly_pos): Call weekdaynum instead of weekdaylist. The interface only lets the user input a single value anyway. * calobj.c (ical_object_to_vobject): instead of code to output day names from a bit array, use instead the value as an int and output a single dayname. * calobj.c (ical_object_generate_events): first_week_day gets the day int instead of the first entry in the bit field. I inserted a fair chunk of code to avoid calling generate if the day is out of range for a month. It may be unneccessary, because mktime will turn the extra days into a valid date the next month. But not all mktimes are equal, I fear. * eventedit.c (ee_store_recur_rule_to_ical): For case 3, (Monthly), I added code to set the interval slot of the recur struct; without this value, selecting a monthly recursing, by date, would lead to an infinite loop broken only by a failure to alloc more memory. Also, in the "by position" case, both u.month_pos and u.month_day were being assigned values. This is a mistake, as they are both part of an union, and the same thing. The weekday field should get the recur_rr_month_weekday value. * eventedit.c (ee_rp_init_rule): set default day from the weekday field instead of the u.month_day field, which is really the month_pos value. * gnome-cal.c (gnome_calendar_tag_calendar): Month days start with 1, not 0; thus, setting tm.tm_mday = 0, and then calling mktime will generate a time corresponding to the end of the previous month, which may have a mday anywhere from 28 to 31. The end time just adds 1 to the month, so your end time may not cover the last few days of this month, depending on what the biggest mday of last month was. I changed it so tm_mday is set to 1 instead. 1999-03-30 Federico Mena Quintero <federico@nuclecu.unam.mx> svn path=/trunk/; revision=792
