NAME

6         Wiki::Toolkit::Feed::Atom - A Wiki::Toolkit plugin to output RecentChanges Atom.
7

DESCRIPTION

9       This is an alternative access to the recent changes of a Wiki::Toolkit
10       wiki. It outputs the Atom Syndication Format as described at
11       <http://www.atomenabled.org/developers/syndication/>.
12
13       This module is a straight port of Wiki::Toolkit::Feed::RSS.
14

SYNOPSIS

16         use Wiki::Toolkit;
17         use Wiki::Toolkit::Feed::Atom;
18
19         my $wiki = Wiki::Toolkit->new( ... );  # See perldoc Wiki::Toolkit
20
21         # Set up the RSS feeder with the mandatory arguments - see
22         # C<new()> below for more, optional, arguments.

29                                    my ($node_name, $version) = @_;
30                                    return 'http://example.com/?id=' . uri_escape($node_name) . ';version=' . uri_escape($version);
31                                  },

34         );
35
36         print "Content-type: application/atom+xml\n\n";

44           site_name            => 'My Wiki',

51           html_equiv_link  => 'http://example.com/?RecentChanges',,
52           atom_link => 'http://example.com/?action=rc;format=atom',
53
54           # Optional arguments:
55           site_description     => 'My wiki about my stuff',
56           software_name        => $your_software_name,     # e.g. "Wiki::Toolkit"
57           software_version     => $your_software_version,  # e.g. "0.73"
58           software_homepage    => $your_software_homepage, # e.g. "http://search.cpan.org/dist/CGI-Wiki/"
59           encoding             => 'UTF-8'
60         );
61
62       "wiki" must be a Wiki::Toolkit object. "make_node_url", if supplied,
63       must be a coderef.
64
65       The mandatory arguments are:
66
67       ·   wiki
68
69       ·   site_name
70
71       ·   site_url
72
73       ·   make_node_url
74
75       ·   html_equiv_link or recent_changes_link
76
77       ·   atom_link
78
79       The three optional arguments
80
81       ·   software_name
82
83       ·   software_version
84
85       ·   software_homepage
86
87       are used to generate the "generator" part of the feed.
88
89       The optional argument
90
91       ·   encoding
92
93       will be used to specify the character encoding in the feed. If not set,
94       will default to the wiki store's encoding.
95
96   "recent_changes()"
97         $wiki->write_node(
98                            'About This Wiki',
99                            'blah blah blah',
100                                $checksum,
101                                {
102                                  comment  => 'Stub page, please update!',
103                                  username => 'Fred',
104                                }
105         );
106
107         print "Content-type: application/atom+xml\n\n";
108         print $atom->recent_changes;
109
110         # Or get something other than the default of the latest 15 changes.
111         print $atom->recent_changes( items => 50 );
112         print $atom->recent_changes( days => 7 );
113
114         # Or ignore minor edits.
115         print $atom->recent_changes( ignore_minor_edits => 1 );
116
117         # Personalise your feed further - consider only changes
118         # made by Fred to pages about bookshops.
119         print $atom->recent_changes(
120                    filter_on_metadata => {
121                                username => 'Fred',
122                                category => 'Bookshops',
123                              },
124                     );
125
126       If using "filter_on_metadata", note that only changes satisfying all
127       criteria will be returned.
128
129       Note: Many of the fields emitted by the Atom generator are taken from
130       the node metadata. The form of this metadata is not mandated by
131       Wiki::Toolkit. Your wiki application should make sure to store some or
132       all of the following metadata when calling "write_node":
133
134       comment - a brief comment summarising the edit that has just been made;
135       will be used in the summary for this item.  Defaults to the empty
136       string.
137       username - an identifier for the person who made the edit; will be used
138       as the Dublin Core contributor for this item, and also in the RDF
139       description.  Defaults to 'No description given for change'.
140       host - the hostname or IP address of the computer used to make the
141       edit; if no username is supplied then this will be used as the author
142       for this item.  Defaults to 'Anonymous'.
143
144   "generate_node_list_feed"
145       Generate and return an Atom feed for a list of nodes
146
147   "generate_node_name_distance_feed"
148       Generate a very cut down atom feed, based just on the nodes, their
149       locations (if given), and their distance from a reference location (if
150       given).
151
152       Typically used on search feeds.
153
154   "feed_timestamp()"
155         print $atom->feed_timestamp();
156
157       Returns the timestamp of the feed in POSIX::strftime style ("Tue, 29
158       Feb 2000 12:34:56 GMT"), which is equivalent to the timestamp of the
159       most recent item in the feed. Takes the same arguments as
160       recent_changes(). You will most likely need this to print a Last-
161       Modified HTTP header so user-agents can determine whether they need to
162       reload the feed or not.
163
164   "parse_feed_timestamp"
165       Take a feed_timestamp and return a Time::Piece object.
