  Wiki::Toolkit::Feed::Atom - 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:

The three optional arguments

are used to generate the generator part of the feed.

The optional argument

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.
