DESCRIPTION

This role will extend its receiving class with a "from_yaml" method. It requires that the receiver has add_group, add_feed, and add_rule methods, and accepts a name attribute to its constructor.

METHODS

from_yaml

my $receiver_instance = Receiver::Class->from_yaml( $config );

Create a new instance of the receiving class (using the top-level name in $config as its name), then create subgroups and add feeds or rules to it (or its subgroups).

$config may have four keys:

• name - name of this group

• groups - list of associative arrays for subgroups, same schema as the original config

• feeds - list of feeds to fetch

• rules - list of rules to apply
