NAME
Set::Crontab - Expand crontab(5)-style integer listsSYNOPSIS
$s = Set::Crontab->new(``1-9/3,>15,>30,!23'', [0..30]);if ($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.
