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 the crontab(5) manpage. A few extensions to the standard syntax are described below. < and > 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. SEE ALSO The crontab(5) manpage.
