Crontab(3) User Contributed Perl Documentation Crontab(3)NAMESet::Crontab - Expand crontab(5)-style integer lists
SYNOPSIS
$s = Set::Crontab->new("1-9/3,>15,>30,!23", [0..30]);
if ($s->contains(3)) { ... }
DESCRIPTIONSet::Crontab parses crontab-style lists of integers and defines some
utility functions to make it easier to deal with them.
Syntax
Numbers, ranges, *, and step values all work exactly as described in
crontab(5). A few extensions to the standard syntax are described
below.
< and >
<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").
Functions
new($spec, [@range])
Creates a new Set::Crontab object and returns a reference to it.
contains($num)
Returns true if $num exists in the set.
list()
Returns the expanded list corresponding to the set. Elements are in
ascending order.
The functions described above croak if they are called with incorrect
arguments.
