[wp-hackers] Wordpress plugin system

[Denis de Bernardy]

Well, in my case, it was more on the lines of apply smart links this way
when the post is the 'main' post, and that way when it is not. I predict
disasters in the long term for relying on wp globals to do this.

Likewise, feedwordpress changes the url of all of the permalinks of my
recent posts plugins when I enable the 'posts point to their original
source' option.

In any event, the point remains. To take the example of my recent comments
plugin, I would feel much more comfortable with:

$comment = apply_filters('comment_meta', $comment);

Than with:

if ( $comment->comment_author != '' )
	$comment_author = apply_filters('get_comment_author',
$comment->comment_author);
else
	$comment_author = apply_filters('get_comment_author',
$anonymous_name);
$comment_author = apply_filters('comment_author', $comment_author);
$comment_author_email = apply_filters('get_comment_author_email',
$comment->comment_author_email);
$comment_author_email = apply_filters('comment_author',
$comment_author_email);
$comment_author_url = apply_filters('get_comment_author_url',
$comment->comment_author_url);
$comment_author_url = apply_filters('comment_url', $comment_author_url);
$comment_date = mysql2date($date_format, $comment->comment_date);
$comment_date = apply_filters('get_comment_date', $comment_date);
$comment_date_normalized = mysql2date('Y-m-d H:i:s',
$comment->comment_date);
if ( $comment->comment_type == '' )
	$comment->comment_type = 'comment';
$comment_type = apply_filters('get_comment_type', $comment->comment_type);
$comment_excerpt = apply_filters('get_comment_excerpt',
$comment->comment_content);
$comment_excerpt = apply_filters('comment_excerpt', $comment_excerpt);
$comment_excerpt = strip_tags($comment_excerpt);
$comment_excerpt = preg_replace( "/\s+\S{". ($max_word_length+1)
.",}(\s|\S)+/", "...", $comment_excerpt);
$comment_excerpt = preg_replace ( "/^\s*(\S+(\s+\S+){". ($excerpt_length-1)
."})(...)?\s*(\S|\s)*/", "$1...", $comment_excerpt);
