73             =head1 DESCRIPTION
74              
75             The module is created with a purpose to provide functionality for handling a
76             personal calendar schedule in a transparent and simple way. The calendar
77             data is assumed to be kept in a plain file in a format easy to edit and
78             understand. It was inspired by the C program on older Unix-like
79             systems, which used C<~/.calendar> file to produce entries for each day
80             and send them in the morning by email.
81              
82             Inspired by the C<~/.calendar> file, the format for recording scheduled
83             events is very simple, mostly contained in one line of text.
84              
85             The module currently supports generation of HTML weekly tables with visual
86             representation of scheduled events. The generated table is generated in
87             a simple HTML table, with a use of C and C attributes to
88             represent overlapping events in parallel in the table.
89              
90             =head2 Planned Future Work
91              
92             In the development of the recording format for the event, there is an attempt
93             to model the data representation of the iCalendar standard (RFC2445).
94             Examples of the iCalendar fields are: DTSTART, DTEND, SUMMARY,
95             RRULE (e.g. RRULE:FREQ=WEEKLY, RRULE:FREQ=WEEKLY;INTERVAL=2 for
96             biweekly, RRULE:FREQ=WEEKLY;UNTIL=20040408 ) etc.
97             More examples:
98              
99             RRULE:FREQ=MONTHLY;BYDAY=TU;BYSETPOS=3
100              
101             Every third Tuesday in a month.
102              
103             =head1 EXAMPLES
104              
105             First example:
106              
107             use Calendar::Schedule qw/:all/;
108              
109             my $TTable = Calendar::Schedule->new();
110              
111             # manually adding an entry
112             $TTable->add_entry('2003-09-09 Tue 18-20 Some meeting');
113            
114             # reading entries from a file
115             $TTable->add_entries_from("$ENV{'HOME'}/.calendar");
116              
117             # producing entries in HTML tables
118             $TTable->set_first_week('2003-12-15');
119             print "

\n" . $TTable->generate_table();

120             print "

\n" . $TTable->generate_table();

121             print "

\n" . $TTable->generate_table();

122              
123             Example with generating a weekly schedule (example2):
124              
125             use Calendar::Schedule;
126             $TTable = Calendar::Schedule->new();
127             $TTable->{'ColLabel'} = "%A";
128             $TTable->add_entries(<

461              
462             Used as C<$obj-E{StartTime}>. Start time for various uses.
463             Usually it is the the beginning of the first interesting week.
464              
465             =item DefaultRowLabels
466              
467             Used as C<$obj-E{DefaultRowLabels}>. Includes pre-defined labels
468             for rows of the generated HTML schedule tables. The pre-defined value
469             is:
470              
471             $self->{DefaultRowLabels} = [qw( 08:00 12:00 17:00 )];

508             =item set_first_week(time)
509              
510             sets start time at the last Monday before given date. It is used in generate_table.
511             Examples:
512              
513             $TTable = Calendar::Schedule->new();
514             $TTable->set_first_week('now');
515             $TTable->set_first_week('2016-02-19');
516              
517             See parse_time for examples for specifying time.

529              
530             sets C pattern for column (day) labels. The default pattern
531             is "C<%AEbrE%Y-%m-%d>", which produces labels like:
532              
533             Friday
534             2003-12-19
535              
536             In order to have just a weekday name, use "C<%A>".

562              
563             =item parse_time(time_specification[,prefix])
564              
565             Parses time specification and returns the calendar time (see mktime in
566             Perl). The functions dies if the time cannot be completely recognized.
567             If prefix is set to true (1), then only a prefix of the string can be
568             a time specification. If prefix is set to 1, then in an array context
569             it will return a 2-element list: the calendar time and the
570             remainder of the string. Format examples:

617              
618             Adds more entries. Each entry may contain several entries separated
619             by a new-line, except if the line ends with \.
620             Empty lines and lines that start with \s*# are ignored.

636              
637             =item add_entry(list_of_entries)
638              
639             Adds more entries. It is different from add_entries because this
640             method does not break entries on new-lines, although it does accept a
641             list of entries as arguments.
642

644              
645             $TTable->add_entry('Mon 8-17', 'Labour Day');
