Atom-based comment feed

[kurtmckee]

I've created an Atom 0.3 comment feed. Holizz (holizz.com) updated the code to be Atom 1.0 compliant. It is coded against WordPress 1.5.2.

Fixed incorrect xml:base and id output

Note for the wp-commentsatom.php to work correctly with rewritten urls in Wordpress 2.x this function has to be updated to the following in wp-includes/functions.php

function do_feed_atom($for_comments) {
if ( $for_comments ) {
load_template(ABSPATH . 'wp-commentsatom.php');
} else {
load_template(ABSPATH . 'wp-atom.php');
}
}

Wordpress is WAY overdue to have working ATOM 1.0 feeds and it's super easy to add into the next alpha release with all the groundword already done.

Is this something that the devs want in the core?

Also, the patch is outdated. I can work on a new one.

Waiting on feedback.

(Out-of-Trac feedback)

Add the template as wp-includes/feed-atom-comments.php.

Update do_feed_atom() to handle withcomments.

Update do_feed() to not assume comment feeds are always rss2.

I'm on it. :)

Added preliminary patch that NEEDS looking over. I *believe* I did everything right, but then again...

Okay, I found one error already: I use bloginfo_rss('content_type') instead of bloginfo_rss('html_type'). I'll fix this in the morning.

(In [4928]) Atom comments feed. First pass. Props kurtmckee and rob1n. fixes #1785
