=head1 NAME

Babble::Processors - Processor collection for Babble

=head1 DESCRIPTION

C<Babble::Processors> is a collection of processors for Babble. All of
the processors herein are run by default, and cannot be turned off,
unless one fiddles with a Babble objects internals.

However, the processors are documented here, so that if one does turn
them off, may he be able to re-use any of these.

=head1 METHODS

=item master()

Adds a B<master> key to the I<item>: the B<id> key of the
I<channel>.

This is useful when one wants to link back to the original channel
from each and every item.

=cut

sub master {
	my ($item, $channel) = @_;

	$$item->{master} = $$channel->{id};
}

=pod

=item image()

Adds an B<image> key to the I<item>: the feed image of the I<channel>.

=cut

sub image {
	my ($item, $channel) = @_;

	$$item->{image} = $$channel->{image};
}

=pod

=item creator()

Sets the author of the item to the I<source>'s B<-id> field, if the
item does not have an author yet.

=cut

sub creator {
	my ($item, undef, $source) = @_;

	$$item->{author} = $$source->{-id} unless $$item->{author};
}

=pod

=item default()

This processor runs all of the others, in the specified order, after
each other.
