=head1 NAME
Perlanet::Trait::OPML - generate an OPML file
=head1 SYNOPSIS
my $perlanet = Perlanet->new_with_traits(
traits => [ 'Perlanet::Trait::OPML' ]
);
$perlanet->run;
=head1 DESCRIPTION
Generates an OPML file of all feeds that are being aggregated by the planet.
=head1 ATTRIBUTES
=head2 opml_generator
An L<XML::OPML::SimpleGen> object to generate the XML for the OPML file
=cut
has 'opml_generator' => (
is => 'rw',
isa => 'Maybe[XML::OPML::SimpleGen]',
lazy_build => 1,
predicate => 'has_opml'
);
sub _build_opml_generator {
my $self = shift;
eval { require XML::OPML::SimpleGen; };
if ($@) {
carp 'You need to install XML::OPML::SimpleGen to enable OPML ' .
'support';
$self->opml(undef);
return;
}
my $loc = setlocale(LC_ALL, 'C');
my $opml = XML::OPML::SimpleGen->new;
setlocale(LC_ALL, $loc);
$opml->head(
title => $self->title,
);
return $opml;
}
=head2 opml_file
Where to save the OPML feed when it has been created
=cut
has 'opml' => (
isa => 'Maybe[Str]',
is => 'rw',
);
=head1 METHODS
=head2 update_opml
Updates the OPML file of all contributers to this planet. If the L<opml>
attribute does not have a value, this method does nothing, otherwise it inserts
each author into the OPML file and saves it to disk.
=cut
sub update_opml {
my ($self, @feeds) = @_;
return unless $self->has_opml;
foreach my $f (@feeds) {
$self->opml_generator->insert_outline(
title => $f->title,
text => $f->title,
xmlUrl => $f->url,
htmlUrl => $f->url,
);
}
$self->save_opml;
}
=head2 save_opml
Save the OPML file, by default to disk.
=cut
sub save_opml {
my $self = shift;
$self->opml_generator->save($self->opml);
}
around 'fetch_feeds' => sub {
my $orig = shift;
my ($self, @feeds) = @_;
@feeds = $self->$orig(@feeds);
$self->update_opml(@feeds) if $self->has_opml;
return @feeds;
};
