[ FeedPP=> {
content_type => 'application/rss+xml',
charset => 'UTF-8',
} ],
],
example code.
my $view= $e->view('FeedPP');
my $feed= $view->feed;
$feed->title('MY BLOG');
$feed->link('http://myblog.domain.name/');
for my $item (@items) {
$feed->add_item( $item->{url},
title => $item->{title},
description => $item->{description},
);
}
print $view->render;
DESCRIPTION
It is a module to use XML::FeedPP with VIEW.
I think that you should operate the XML::FeedPP object directly from the feed method though some methods of XML::FeedPP do bind.
It has the function to cache feeding that XML::FeedPP generated. * Egg::Plugin::Cache is used.
CONFIGURATION
'FeedPP' is added to the setting of VIEW.
VIEW=> [ [ FeedPP=> { ... option ... } ] ],
content_type
Contents type when outputting it.
Default is 'application/rss+xml'.
charset
Character set when outputting it.
Default is 'UTF-8'.
cache_name
If the cash function is used, the cash name to use Egg::Plugin::Cache is set.
* Even if cash is used, it is not indispensable because the thing specified when the cash function is called can be done.
see Egg::Plugin::Cache.
METHODS
new
The object of this View is returned.
my $view= $e->view('FeedPP');
cache ( [CACHE_KEY] or [CACHE_NAME], [CACHE_KEY] {, [EXPIRES] } )
The cash function is made effective.
* Thing that can be used by Egg::Plugin::Cache's being appropriately set.
CACHE_KEY is only passed if 'cache_name' is set with CONFIGURATION.
When CACHE_NAME is passed, the cash is used. * It gives priority more than set of 'cache_name'.
EXPIRES is validity term to pass it to the set method when Cache::Memcached is used with Egg::Plugin::Cache. * It is not necessary usually.
my $expr= 60* 60; # one hour.
my $view= $e->view('FeedPP');
unless ($view->cache('CACHE_NAME', 'CACHE_KEY', $expr)) {
#
# RSS feed generation code.
#
my $feed= $view->feed;
$feed->title('MYBLOG');
....
....
# ----------------
}
* 'RSS feed generation code' part from the unless sentence though the image might not be gripped easily for a moment You only have to move as usual even if it removes.
Anything need not be done excluding this. If cash becomes a hit, the content of cash is output with output.
feed_type ( [FEED_TYPE] )
The type of the generation feeding to use it by the feed method is returned.
The value that can be specified for FEED_TYPE is rss, rdf, and atom.
FEED_TYPE returns and 'RSS' always returns when it is not given or wrong specification is done.
# Example of generating key to cash with value obtained from URI.
# example uri = http://domain/xml/hoge/rdf
#
my $feed_type= $view->feed_type( $e->snip->[2] );
$view->cache('FileCache', "xml_hoge_${feed_type}") || do {
my $feed= $view->feed($feed_type);
.....
...
};
feed ( [FEED_TYPE] )
The XML::FeedPP object is returned.
When FEED_TYPE is specified, the corresponding module is read.
If FEED_TYPE unspecifies it, 'RSS' is processed to have specified it.
my $feed= $view->feed('Atom');
see XML::FeedPP.
reset
The XML::FeedPP context set in View is erased.
render
To_string of XML::FeedPP is called and feeding is generated.
If cash is effective, the content of cash is returned.
my $feed_text= $view->render($feed);
output
The result of the render method is received, and set contents type and contents body are set in Egg::Response.
$view->output($feed);
* It is not necessary to call it from the project code because it is called by the operation of Egg usually.
BINDING METHODS
Tentatively, Messod of following XML::FeedPP that seems to be necessary for the feeding generation it is done and bind is done to this View.
item, title, pubDate, link, add_item, merge, remove_item, clear_item, sort_item, uniq_item, limit_item, normalize
