Set::Crontab - Expand crontab(5)-style integer lists
$s = Set::Crontab->new("1-9/3,>15,>30,!23", [0..30]);
if ($s->contains(3)) { ... }
Set::Crontab parses crontab-style lists of integers and defines some utility functions to make it easier to deal with them.
Numbers, ranges, *, and step values all work exactly as described in crontab(5). A few extensions to the standard syntax are described below.
<N selects the elements smaller than N from the entire range, and adds them to the set. >N does likewise for elements larger than N.
!N excludes N from the set. It applies to the other specified range; otherwise it applies to the specified ranges (i.e. "!3" with a range of "1-10" corresponds to "1-2,4-10", but ">3,!7" in the same range means "4-6,8-10").
Creates a new Set::Crontab object and returns a reference to it.
Returns true if $num exists in the set.
Returns the expanded list corresponding to the set.
The functions described above croak if they are called with incorrect arguments.
