I noticed now that I do not have calendars listed in ~/library/calendars.

I look in ~/library/application support/ical and have some files and in the Sync Services folder. (Also have another folder named Sync Service with no s on end of service.)

The files also have some crazy labeling scheme. They are not labeled the same as in iCal. Am I seeing things? Why was this done?

I think the idea is that they generalized iCal's calendars, so they need not be simple .ics files (like the birthday calendar, for example). They also moved some of the settings like subscription information locally to each calendar's folder.

I wrote this little Perl script to make symlinks into the old ~/Library/Calendars location, if you use them for any reason (I use those files to show availability information on my work homepage...)

Code:
#!/usr/bin/perl
use warnings;
use strict;

# FILE: ical_links.pl
# AUTHOR: Mithras The Prophet (mithras.the.prophet, which is a gmail account)
# PURPOSE: makes symlinks from new Tiger iCal calendars to old ~/Library/Calendars location
# HISTORY: 
#   04/26/2005 - initial version

#
## Settings
my $source_dir="$ENV{HOME}/Library/Application Support/iCal/Sources";
my $source_calendar_filename="corestorage.ics";
my $target_dir="$ENV{HOME}/Library/Calendars";
##
#

# 1. scan the source directory for appropriate calendars
my @calendars; # this will hold hashes of name & location

opendir(SOURCE_DIR, $source_dir)
	or die("Can't access source calendars in '$source_dir'\n");
while (my $subdir = readdir(SOURCE_DIR)) {
	# only use .calendar directories that have a corestorage file
	if (-d "$source_dir/$subdir" 
		&& $subdir =~ m/\.calendar$/
		&& (-e "$source_dir/$subdir/$source_calendar_filename")) {
		
		# We have an appropriate calendar
		# 2. record the location
		my %thiscal;
		$thiscal{'location'} = "$source_dir/$subdir/$source_calendar_filename";

		# 3. Extract the calendar title
		open (CAL_INFO, "$source_dir/$subdir/Info.plist")
			or die("Can't get information on calendar: $source_dir/$subdir\n");
		my $title_next = 0;
		while (<CAL_INFO>) {
			if (m/<key>Title<\/key>/) {
				$title_next = 1;
			}
			if ($title_next && m/<string>([^<]+)<\/string>/) {
				$thiscal{'title'} = $1;
				$title_next = 0;
			}
		}
		close(CAL_INFO);
		
		# 4. Add this calendar to the list
		push(@calendars, \%thiscal);
	}
}
close( SOURCE_DIR );

#
# Step 5: make symlinks
#
foreach my $cal_ref (@calendars) {
	my $newfile = $target_dir . '/' . $cal_ref->{'title'} . '.ics';
	print "Linking $newfile -> " . $cal_ref->{'location'} . "\n";
	symlink( $cal_ref->{'location'}, $newfile );
	;
}

Holy cow Mithras. You are in a different stratosphere! I'm a low flyin' bird.

Okay. So I guess they did change things. Now my next questions.

Syncing to .Mac. Calendars not showing up. Is this working yet?

How do I do a simple backup of my calendars. Used to just go the calendars file, option click and drag into a folder.

Now I am stumped. I do backups on an external disk but I am very guarded of my addressbook and iCal. Addressbook has a built in backup feature. Not so for iCal. Any ideas?

EDIT: Just realized that iCal has a database backup command in the menubar. Nice. (Maybe this was with Panther? If so, feel like a real clown.)
