Wiki::Toolkit::Feed::Atom(3) A Wiki::Toolkit plugin to output RecentChanges Atom.


This is an alternative access to the recent changes of a Wiki::Toolkit wiki. It outputs the Atom Syndication Format as described at <>.

This module is a straight port of Wiki::Toolkit::Feed::RSS.


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 => $wiki,
site_name => 'My Wiki',
site_url => '',
make_node_url => sub
my ($node_name, $version) = @_;
return '' . uri_escape($node_name) . ';version=' . uri_escape($version);
html_equiv_link => '',
atom_link => ';format=atom',
print "Content-type: application/atom+xml\n\n";
print $atom->recent_changes;



  my $atom = Wiki::Toolkit::Feed::Atom->new(
    # Mandatory arguments:
    wiki                 => $wiki,
    site_name            => 'My Wiki',
    site_url             => '',
    make_node_url        => sub
                              my ($node_name, $version) = @_;
                              return '' . uri_escape($node_name) . ';version=' . uri_escape($version);
    html_equiv_link  => '',,
    atom_link => ';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. ""
    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.


                     'About This Wiki',
                     'blah blah blah',
                           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 and return an Atom feed for a list of nodes


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.


  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.


Take a feed_timestamp and return a Time::Piece object.
