Well, I made two tweaks to feed.php that may interest others:
(1) When $conf['rss_useheading'] evaluates true, the RSS entry is titled after
the first heading on the page, rather than after the page ID. I wasn't sure if
I should use $conf['useheading'].
(2) When $conf['rss_skiptopara'] evaluates true, the RSS entry description
begins at the first <p> tag of the page. This allows a person browsing RSS to
get readable text from the get-go, rather than requiring the user to have to
wade through the page title, technorati tags, the date (if you're using #dt()#,
as I am), etc., in order to get to the first sentence on the page. Maybe
someone can suggest a better config variable name.
This requires changing rssRecentChanges() so that the foreach begins as follows:
foreach(array_keys($recents) as $id){
list($title, $desc) = rssGetContent($id);
$item = new FeedItem();
$item->title = $title;
And it requires adding this function:
function rssGetContent($id) {
global $conf;
$title = $id;
$xhtml = p_wiki_xhtml($id,'',false);
if($conf['rss_useheading']) {
$heading = p_get_first_heading($id);
if(!empty($heading))
$title = trim($heading);
}
if($conf['rss_skiptopara']) {
$startPara = strpos($xhtml, '<p>');
if($startPara !== false)
$xhtml = substr($xhtml, $startPara);
}
return array($title, cleanDesc($xhtml));
}
