Set::Crontab

Crontab(3)	     User Contributed Perl Documentation	   Crontab(3)



NAME
       Set::Crontab - Expand crontab(5)-style integer lists

SYNOPSIS
       $s = Set::Crontab->new("1-9/3,>15,>30,!23", [0..30]);

       if ($s->contains(3)) { ... }

DESCRIPTION
       Set::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.

       The functions described above croak if they are called with incorrect
       arguments.
