I started from the 78ec8e commit then cherry-picked and squashed commits that have been done in master since then, except the bad commits that overwrote the tree (in master) with the tree in maint. This commit also bumps the version number to 7.8.06. The only "fix" that was made between 78ec8e and the previous commit is e0072f which has been reported to break stuff.

|
;; This file provides the import of events from Mac OS X 10.5 iCal.app
|
|
;; into the Emacs diary (it is not compatible with OS X < 10.5). The
|
|
;; function org-mac-iCal will import events in all checked iCal.app
|
|
;; calendars for the date range org-mac-iCal-range months, centered
|
|
;; around the current date.
|
|
;;
|
|
;; CAVEAT: This function is destructive; it will overwrite the current
|
|
;; contents of the Emacs diary.
|
|
;;
|
|
;; Installation: add (require 'org-mac-iCal) to your .emacs.
|
|
;;
|
|
;; If you view Emacs diary entries in org-agenda, the following hook
|
|
;; will ensure that all-day events are not orphaned below TODO items
|
|
;; and that any supplementary fields to events (e.g. Location) are
|
|
;; grouped with their parent event
