NAME
Wiki::Toolkit::Feed::Atom - A Wiki::Toolkit plugin to output RecentChanges Atom.
DESCRIPTION
This is an alternative access to the recent changes of a Wiki::Toolkit wiki. It outputs the Atom Syndication Format as described at <http://www.atomenabled.org/developers/syndication/>.
This module is a straight port of Wiki::Toolkit::Feed::RSS.
SYNOPSIS
use Wiki::Toolkit;use Wiki::Toolkit::Feed::Atom;my $wiki = Wiki::Toolkit->new( ... ); # See perldoc Wiki::Toolkit# Set up the RSS feeder with the mandatory arguments - see# C<new()> below for more, optional, arguments.my $atom = Wiki::Toolkit::Feed::Atom->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',atom_link => 'http://example.com/?action=rc;format=atom',);print "Content-type: application/atom+xml\n\n";print $atom->recent_changes;
METHODS
"new()"
my $atom = Wiki::Toolkit::Feed::Atom->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',,atom_link => 'http://example.com/?action=rc;format=atom',# Optional arguments:site_description => 'My wiki about my stuff',software_name => $your_software_name, # e.g. "Wiki::Toolkit"software_version => $your_software_version, # e.g. "0.73"software_homepage => $your_software_homepage, # e.g. "http://search.cpan.org/dist/CGI-Wiki/"encoding => 'UTF-8');
"wiki" must be a Wiki::Toolkit object. "make_node_url", if supplied, must be a coderef.
The mandatory arguments are:
- •
-
wiki
- •
-
site_name
- •
-
site_url
- •
-
make_node_url
- •
-
html_equiv_link or recent_changes_link
- •
-
atom_link
The three optional arguments
- •
-
software_name
- •
-
software_version
- •
-
software_homepage
are used to generate the "generator" part of the feed.
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/atom+xml\n\n";print $atom->recent_changes;# Or get something other than the default of the latest 15 changes.print $atom->recent_changes( items => 50 );print $atom->recent_changes( days => 7 );# Or ignore minor edits.print $atom->recent_changes( ignore_minor_edits => 1 );# Personalise your feed further - consider only changes# made by Fred to pages about bookshops.print $atom->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 Atom 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 summary 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 'No description given for change'.
- 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 author for this item. Defaults to 'Anonymous'.
"generate_node_list_feed"
Generate and return an Atom feed for a list of nodes
"generate_node_name_distance_feed"
Generate a very cut down atom 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()"
print $atom->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.
"parse_feed_timestamp"
Take a feed_timestamp and return a Time::Piece object.
