=head1 NAME

WebService::Strike - Get torrent info from getstrike.net API

=head1 SYNOPSIS

  use WebService::Strike;
  my $t = strike 'B425907E5755031BDA4A8D1B6DCCACA97DA14C04';
  say $t->title;               # Arch Linux 2015.01.01 (x86\/x64)
  say $t->magnet;              # Returns a magnet link
  my $torrent = $t->torrent;   # Returns the torrent file
  $t->torrent('file.torrent'); # Downloads the torrent file to 'file.torrent'

  my @debian = strike_search 'Debian';
  say 'Found ' . @debian . ' torrents matching "Debian"';
  say 'First torrent has info hash ' . $debian[0]->hash;

  my $mp = strike_search 'Modern perl', 1, category => 'Books';
  say 'Torrent has ' . $mp->count . ' files. They are:';
  say join ' ', @{$mp->file_names};

  my $info = strike_imdb 'tt1520211';
  say 'IMDB ID ', $info->{imdbid}, ' is ', $info->{title}, ' (', $info->{year}, ')';
  say 'Plot (short): ', $info->{shortplot};

=head1 DESCRIPTION

Strike API is a service for getting information about a torrent given
its info hash. WebService::Strike is a wrapper for this service.

=over

=item B<strike>(I<@info_hashes>)

Returns a list of L<WebService::Strike::Torrent> objects in list
context or the first such object in scalar context. Dies in case of
error.

=item B<strike_query>

Alias for B<strike>. Not exported by default.

=item B<strike_search>(I<$phrase>, [I<$full>, [ key => value ... ]])

Searches for torrents given a phrase. Returns a list of
L<WebService::Strike::Torrent> objects in list context or the first
such object in scalar context.

If I<$full> is false (default), the returned objects will be
incomplete: their B<file_names> and B<file_lengths> accessors will
return undef.

If I<$full> is true, B<strike> will be called with the info hashes of
the found torrents, thus obtaining complete objects.

You can filter the search by appending key => value pairs to the call.
For example:

  strike_search 'windows', 0, category => 'Applications', sub_category => 'Windows';

=item B<strike_imdb>(I<$imdb_id>)

Get informaton about a movie from IMDB. Takes an IMDB ID and returns a
hashref of unspecified format. All keys are lowercased.
