debugging here - I've written this:
---
use DateTime;
use DateTime::Event::Recurrence;
my $startDate = DateTime->new(
year => 2016,
month => 2,
day => 10,
hour => 17,
minute => 51,
second => 31,
nanosecond => 123456,
time_zone => 'America/Chicago',
);
my $count = 15;
my $startDay = DateTime->from_object( object => $startDate
)->truncate( to => 'day' );
my $iterator = DateTime::Event::Recurrence->weekly( days => [ 1 .. 5 ]
)->iterator(
after => DateTime->from_object(
object => $startDay
),
);
my @result = ();
while ( $count-- ) {
my $date = $iterator->next;
print "$date ", $date->day_of_week(), "\n";
}
---
troubleshooting steps:
I would try again without calling isHoliday($date) inside the loop.
This is to rule out that $date is being modified.
Alternately, specify a bounded recurrence (one with start and end
dates). This is to force precalculation of the set, before the
iterator starts. For example, using DateTime::Event::ICal:
---
use DateTime;
use DateTime::Event::ICal;
my $startDate = DateTime->new(
year => 2016,
month => 2,
day => 10,
hour => 17,
minute => 51,
second => 31,
nanosecond => 123456,
time_zone => 'America/Chicago',
);
my $startDay = DateTime->from_object( object => $startDate
)->truncate( to => 'day' )->add( days => 1 );
my $iterator = DateTime::Event::ICal->recur(
dtstart => $startDay,
freq => 'weekly',
byday => [ "mo", "tu", "we", "th", "fr" ],
count => 15,
)->iterator();
my @result = ();
while ( my $date = $iterator->next ) {
print "$date ", $date->day_of_week(), "\n";
}
---
please let me know what you get.
