NAME¶
Wiki::Toolkit::Feed::RSS - Output RecentChanges RSS for Wiki::Toolkit.
DESCRIPTION¶
This is an alternative access to the recent changes of a Wiki::Toolkit wiki. It outputs RSS as described by the ModWiki proposal at <http://www.usemod.com/cgi-bin/mb.pl?ModWiki>
SYNOPSIS¶
use Wiki::Toolkit; use Wiki::Toolkit::Feed::RSS; my $wiki = CGI::Wiki->new( ... ); # See perldoc Wiki::Toolkit # Set up the RSS feeder with the mandatory arguments - see # C<new()> below for more, optional, arguments. my $rss = Wiki::Toolkit::Feed::RSS->new( wiki => $wiki, site_name => 'My Wiki', site_url => 'http://example.com/', make_node_url => sub { my ($node_name, $version) = @_; return 'http://example.com/?id=' . uri_escape($node_name) . ';version=' . uri_escape($version); }, html_equiv_link => 'http://example.com/?RecentChanges', encoding => 'UTF-8' ); print "Content-type: application/xml\n\n"; print $rss->recent_changes;
METHODS¶
"new()"¶
my $rss = Wiki::Toolkit::Feed::RSS->new( # Mandatory arguments: wiki => $wiki, site_name => 'My Wiki', site_url => 'http://example.com/', make_node_url => sub { my ($node_name, $version) = @_; return 'http://example.com/?id=' . uri_escape($node_name) . ';version=' . uri_escape($version); }, html_equiv_link => 'http://example.com/?RecentChanges', # Optional arguments: site_description => 'My wiki about my stuff', interwiki_identifier => 'MyWiki', make_diff_url => sub { my $node_name = shift; return 'http://example.com/?diff=' . uri_escape($node_name) }, make_history_url => sub { my $node_name = shift; return 'http://example.com/?hist=' . uri_escape($node_name) }, software_name => $your_software_name, # e.g. "CGI::Wiki" software_version => $your_software_version, # e.g. "0.73" software_homepage => $your_software_homepage, # e.g. "http://search.cpan.org/dist/Wiki-Toolkit/" );
"wiki" must be a Wiki::Toolkit object. "make_node_url", and "make_diff_url" and "make_history_url", if supplied, must be coderefs.
The mandatory arguments are:
- wiki
- site_name
- site_url
- make_node_url
- html_equiv_link or recent_changes_link
The three optional arguments
- software_name
- software_version
- software_homepage
are used to generate DOAP (Description Of A Project - see <http://usefulinc.com/doap>) metadata for the feed to show what generated it.
The optional argument
- •
- encoding
will be used to specify the character encoding in the feed. If not set, will default to the wiki store's encoding.
"recent_changes()"¶
$wiki->write_node( 'About This Wiki', 'blah blah blah', $checksum, { comment => 'Stub page, please update!', username => 'Fred', } ); print "Content-type: application/xml\n\n"; print $rss->recent_changes; # Or get something other than the default of the latest 15 changes. print $rss->recent_changes( items => 50 ); print $rss->recent_changes( days => 7 ); # Or ignore minor edits. print $rss->recent_changes( ignore_minor_edits => 1 ); # Personalise your feed further - consider only changes # made by Fred to pages about bookshops. print $rss->recent_changes( filter_on_metadata => { username => 'Fred', category => 'Bookshops', }, );
If using "filter_on_metadata", note that only changes satisfying all criteria will be returned.
Note: Many of the fields emitted by the RSS generator are taken from the node metadata. The form of this metadata is not mandated by Wiki::Toolkit. Your wiki application should make sure to store some or all of the following metadata when calling "write_node":
- comment - a brief comment summarising the edit that has just been made; will be used in the RDF description for this item. Defaults to the empty string.
- username - an identifier for the person who made the edit; will be used as the Dublin Core contributor for this item, and also in the RDF description. Defaults to the empty string.
- host - the hostname or IP address of the computer used to make the edit; if no username is supplied then this will be used as the Dublin Core contributor for this item. Defaults to the empty string.
- major_change - true if the edit was a major edit and false if it was a minor edit; used for the importance of the item. Defaults to true (ie if "major_change" was not defined or was explicitly stored as "undef").
"feed_timestamp()"¶
print $rss->feed_timestamp();
Returns the timestamp of the feed in POSIX::strftime style ("Tue, 29 Feb 2000 12:34:56 GMT"), which is equivalent to the timestamp of the most recent item in the feed. Takes the same arguments as recent_changes(). 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.
"generate_node_list_feed"¶
Generate and return an RSS feed for a list of nodes
"generate_node_name_distance_feed"¶
Generate a very cut down rss feed, based just on the nodes, their locations (if given), and their distance from a reference location (if given).
Typically used on search feeds.
"feed_timestamp"¶
Generate the timestamp for the RSS, based on the newest node (if available). Will return a timestamp for now if no node dates are available
"parse_feed_timestamp"¶
Take a feed_timestamp and return a Time::Piece object.
