VERSION

10       14, 2015 as part of Palm version 1.400.

SYNOPSIS

13           use Palm::Datebook;
14

DESCRIPTION

16       The Datebook PDB handler is a helper class for the Palm::PDB package.
17       It parses DateBook and Calendar databases.
18
19   AppInfo block
20       The AppInfo block begins with standard category support. See
21       Palm::StdAppInfo for details.
22
23   Sort block
24           $pdb->{sort}
25
26       This is a scalar, the raw data of the sort block.
27
28   Records
29           $record = $pdb->{records}[N]
30
31           $record->{day}
32           $record->{month}
33           $record->{year}
34
35       The day, month and year of the event. The day and month start at 1
36       (i.e., for January, "$record->{month}" is set to 1). The year is a
37       four-digit number (for dates in 2001, "$record->{year}" is "2001").
38
39       For repeating events, these fields specify the first date at which the
40       event occurs.
41
42           $record->{start_hour}
43           $record->{start_minute}
44           $record->{end_hour}
45           $record->{end_minute}
46
47       The start and end times of the event. For untimed events, all of these
48       are 0xff.
49
50           $record->{when_changed}
51
52       This is defined and true iff the "when info" for the record has
53       changed. I don't know what this means.
54
55           $record->{alarm}{advance}
56           $record->{alarm}{unit}
57
58       If the record has an alarm associated with it, the %{$record->{alarm}}
59       hash exists. The "unit" subfield is an integer: 0 for minutes, 1 for
60       hours, 2 for days. The "advance" subfield specifies how many units
61       before the event the alarm should ring.  e.g., if "unit" is 1 and
62       "advance" is 5, then the alarm will sound 5 hours before the event.
63
64       If "advance" is -1, then there is no alarm associated with this event.
65       New records created via "new_Record" have a 10 minute alarm set by
66       default. "undef $record->{alarm}" to remove this alarm before writing.
67       An alarm icon will still show up in the Datebook if the "alarm" field
68       exists, even with "advance" set to -1.
69
70           %{ $record->{repeat} }
71
72       This exists iff this is a repeating event.
73
74           $record->{repeat}{type}
75
76       An integer which specifies the type of repeat:
77
78       0   no repeat.
79
80       1   a daily event, one that occurs every day.
81
82       2   a weekly event, one that occurs every week on the same day(s). An
83           event may occur on several days every week, e.g., every Monday,
84           Wednesday and Friday.
85
86           For weekly events, the following fields are defined:
87
88               @{ $record->{repeat}{repeat_days} }
89
90           This is an array of 7 elements; each element is true iff the event
91           occurs on the corresponding day. Element 0 is Sunday, element 1 is
92           Monday, and so forth.
93
94               $record->{repeat}{start_of_week}
95
96           Day the week starts on (0 for Sunday, 1 for Monday). This affects
97           the phase of events that repeat every 2nd (or more) Sunday.
98
99       3   a "monthly by day" event, e.g., one that occurs on the second
100           Friday of every month.
101
102           For "monthly by day" events, the following fields are defined:
103
104               $record->{repeat}{weeknum}
105
106           The number of the week on which the event occurs. 0 means the first
107           week of the month, 1 means the second week of the month, and so
108           forth.  A value of 5 means that the event occurs on the last week
109           of the month.
110
111               $record->{repeat}{daynum}
112
113           An integer, the day of the week on which the event occurs. 0 means
114           Sunday, 1 means Monday, and so forth.
115
116       4   a "monthly by date" event, e.g., one that occurs on the 12th of
117           every month.
118
119       5   a yearly event, e.g., one that occurs every year on December 25th.
120
121               $record->{repeat}{frequency}
122
123           Specifies the frequency of the repeat. For instance, if the event
124           is a daily one, and $record->{repeat}{frequency} is 3, then the
125           event occurs every 3 days.
126
127           $record->{repeat}{unknown}
128
129       I don't know what this is.
130
131           $record->{repeat}{end_day}
132           $record->{repeat}{end_month}
133           $record->{repeat}{end_year}
134
135       The last day, month and year on which the event occurs.
136
137           @{ $record->{exceptions} }
138           $day   = $record->{exceptions}[N][0]
139           $month = $record->{exceptions}[N][1]
140           $year  = $record->{exceptions}[N][2]
141
142       If there are any exceptions to a repeating event, e.g. a weekly meeting
143       that was cancelled one time, then the @{$record->{exceptions}} array is
144       defined.
145
146       Each element in this array is a reference to an anonymous array with
147       three elements: the day, month, and year of the exception.
148
149           $record->{description}
150
151       A text string, the description of the event.
152
153           $record->{location}
154
155       A text string, the location (if any) of the event (Calendar database
156       only).
157
158           $record->{note}
159
160       A text string, the note (if any) attached to the event.
161
162           %{ $record->{timezone} }
163
164       This exists iff a time zone has been set for the event.
165
166           $record->{timezone}{name}
167
168       The time zone name, e.g., "London" or "San Francisco".
169
170           $record->{timezone}{country}
171
172       The country the time zone is in. This is an integer defined in
173       Core/System/PalmLocale.h.
174
175           $record->{timezone}{offset}
176
177       This gives the offset from UTC, in minutes, of the time zone.
178
179           $record->{timezone}{dst_adjustment}
180
181       This gives the additional offset while daylight savings time is in
182       effect.  The offset from UTC is $record->{timezone}{offset} +
183       $record->{timezone}{dst_adjustment} (actually only 0 or 60 are used).
184
185           $record->{timezone}{custom}
186
187       Should indicate whether this location was created by the user, though
188       this always seems to be true.
189
190           $record->{timezone}{flags}
191
192       Reserved flags.
193
194           $record->{timezone}{start_hour}
195           $record->{timezone}{start_daynum}
196           $record->{timezone}{start_weeknum}
197           $record->{timezone}{start_month}
198           $record->{timezone}{end_hour}
199           $record->{timezone}{end_daynum}
200           $record->{timezone}{end_weeknum}
201           $record->{timezone}{end_month}
202
203       These define the period during which daylight savings time is in effect
204       if $record->{timezone}{dst_adjustment} is non-zero.  daynum specifies
205       the day of week (0=Sunday, 6=Saturday) and weeknum specifies the week
206       of month (0=1st, 3=4th, 4=last), analagously to the "monthly by day"
207       repeating event.  e.g., The "London" time zone has DST starting on the
208       last Sunday of March, which is indicated with start_daynum=0 (Sunday),
209       start_weeknum=4 (last week of the month), and start_month=3 (March).

METHODS

212   new
213         $pdb = new Palm::Datebook;
214         $pdb = new Palm::Datebook({app => 'Calendar'});
215
216       Create a new PDB, initialized with the various Palm::Datebook fields
217       and an empty record list. Creates a Datebook PDB by default.  Specify
218       the app parameter as 'Calendar' to create a Calendar PDB.
219
220   new_Record
221         $record = $pdb->new_Record;
222
223       Creates a new Datebook record, with blank values for all of the fields.
224
225       "new_Record" does not add the new record to $pdb. For that, you want
226       "$pdb->append_Record".
