NAME

       OpenGuides::Feed - generate data feeds for OpenGuides in various formats.

DESCRIPTION

       Produces RSS 1.0 and Atom 1.0 feeds for OpenGuides.  Distributed and installed as part of the OpenGuides
       project, not intended for independent installation.  This documentation is probably only useful to
       OpenGuides developers.

SYNOPSIS

           use Wiki::Toolkit;
           use OpenGuides::Config;
           use OpenGuides::Feed;

           my $wiki = Wiki::Toolkit->new( ... );
           my $config = OpenGuides::Config->new( file => "wiki.conf" );
           my $feed = OpenGuides::Feed->new( wiki       => $wiki,
                                             config     => $config,
                                             og_version => '1.0', );

           # Ten most recent changes in RSS format.
           my %args = ( items     => 10,
                        feed_type => 'rss',
                        also_return_timestamp => 1 );
           my ($feed_output,$feed_timestamp) = $feed->make_feed( %args );

           print "Content-Type: application/rdf+xml\n";
           print "Last-Modified: " . $feed_timestamp . "\n\n";
           print $feed_output;

METHODS

       new
               my $feed = OpenGuides::Feed->new( wiki       => $wiki,
                                                 config     => $config,
                                                 og_version => '1.0', );

           "wiki" must be a Wiki::Toolkit object and "config" must be an OpenGuides::Config object.  Both of
           these arguments are mandatory.  "og_version" is an optional argument specifying the version of
           OpenGuides for inclusion in the feed.

       rss_maker
           Returns a raw Wiki::Toolkit::Feed::RSS object created with the values you invoked this module with.

       atom_maker
           Returns a raw Wiki::Toolkit::Feed::Atom object created with the values you invoked this module with.

       make_feed
               # Ten most recent changes in RSS format.
               my %args = ( items     => 10,
                            feed_type => 'rss',
                            also_return_timestamp => 1 );
               my ($feed_output,$feed_timestamp) = $rdf_writer->make_feed( %args );

               print "Content-Type: application/rdf+xml\n";
               print "Last-Modified: " . $feed_timestamp . "\n\n";
               print $feed_output;
               print $rdf_writer->make_feed( %args );

               # All the changes made by bob in the past week, ignoring minor edits, in Atom.
               $args{days}               = 7;
               $args{ignore_minor_edits  = 1;
               $args{filter_on_metadata} => { username => "bob" };
               $args{also_return_timestamp} => 1;

               my ($feed_output,$feed_timestamp) = $rdf_writer->make_feed( %args );
               print "Content-Type: application/atom+xml\n";
               print "Last-Modified: " . $feed_timestamp . "\n\n";
               print $feed_output;

       feed_timestamp
           Instead of calling this, you should instead pass in the 'also_return_timestamp' option. You will then
           get back the feed timestamp, along with the feed output.

           This method will be removed in future, and currently will only return meaningful values if your
           arguments relate to recent changes.

               print "Last-Modified: " . $feed->feed_timestamp( %args ) . "\n\n";

           Returns the timestamp of something in POSIX::strftime style ("Tue, 29 Feb 2000 12:34:56 GMT"). Takes
           the same arguments as make_recentchanges_rss().  You will most likely need this to print a Last-
           Modified HTTP header so user-agents can determine whether they need to reload the feed or not.
