SYNOPSIS

use Cronos::Policy;

Cronos::Policy->new( $conf )->dump( $cache );

my $policy = Cronos::Policy->load( $cache );
my $now = time;
my $level = 2;

$policy->set( $now - 86400, $now + 86400 );

my $who = $policy->get( $now, $level );
my %list = $policy->list( $level );

CONFIGURATION

A YAML file that contains a stream of site definitions, each a HASH with the following keys:

required:

pivot: a date expression, for rotation
queue: a list of items to rotate through

optional:

site: default '', name of site
period: default 1
timezone: default 'local'
duration: default '00:00 ~ 23:59'
day: days of coverage, default all
level: levels of coverage, default all
reverse: default 0, reverse escalation order if 1

Coverage is processed in sequential order until met or defaulted to the last site ( or in reverse order, and default to the first site if 'reverse' is set )

Hence duration, level, and day do not apply to the default site.

example:

---
site: cn
pivot: 2013.12.23
queue:
- huey
- dewey
- louie
---
site: us
pivot: 2013.12.23 20:00
timezone: America/Los_Angeles
duration: '19:10 ~ 7:20'
period: 7
level: [ 1, 2 ]
day: [ 1, 2, 3, 4, 5 ]
queue:
- tom
- dick
- harry
