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.
