Wiki::Toolkit::Feed::Listing(3pm) User Contributed Perl Documentation Wiki::Toolkit::Feed::Listing(3pm)NAME
Wiki::Toolkit::Feed::Listing - parent class for Feeds from Wiki::Toolkit.
DESCRIPTION
Handles common data fetching tasks, so that child classes need only worry about formatting the feeds.
Also enforces some common methods that must be implemented.
METHODS
"fetch_recently_changed_nodes"
Based on the supplied criteria, fetch a list of the recently changed nodes
"fetch_newest_for_recently_changed"
Based on the supplied criteria (but not using all of those used by fetch_recently_changed_nodes), find the newest node from the recently
changed nodes set. Normally used for dating the whole of a Feed.
"fetch_node_all_versions"
For a given node (name or ID), return all the versions there have been, including all metadata required for it to go into a "recent
changes" style listing.
"recent_changes"
Build an Atom Feed of the recent changes to the Wiki::Toolkit instance, using any supplied parameters to narrow the results.
If the argument "also_return_timestamp" is supplied, it will return an array of the feed, and the feed timestamp. Otherwise it just returns
the feed.
"node_all_versions"
Build an Atom Feed of all the different versions of a given node.
If the argument "also_return_timestamp" is supplied, it will return an array of the feed, and the feed timestamp. Otherwise it just returns
the feed.
"format_geo"
Using the geo and space xml namespaces, format the supplied node metadata into geo: and space: tags, suitable for inclusion in a feed with
those namespaces imported.
The following are methods that any feed renderer must provide:
"feed_timestamp"
All implementing feed renderers must implement a method to produce a feed specific timestamp, based on the supplied node
"generate_node_list_feed"
All implementing feed renderers must implement a method to produce a feed from the supplied list of nodes
"generate_node_name_distance_feed"
All implementing feed renderers must implement a method to produce a stripped down feed from the supplied list of node names, and
optionally locations and distance from a reference point.
"parse_feed_timestamp"
Take a feed_timestamp and return a Time::Piece object.

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
";
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:
o wiki
o site_name
o site_url
o make_node_url
o html_equiv_link or recent_changes_link
o atom_link
The three optional arguments
o software_name
o software_version
o software_homepage
are used to generate the "generator" part of the feed.
The optional argument
o 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
";
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.
