Tagging with Technorati style in pure Blosxom //at 03:22 //by abe

Short summary: I can’t stay away from coding Blosxom plugins. Perl rules. PHP sucks. ;-)

• New version 0.04 of the tagging plugin, supporting Technorati style tag links to many resources.
• New add-on plugin pathbasedtagging to the plugin tagging, implementing Technorati style tag links in pure Blosxom without any help from Apache’s mod_rewrite.
• New plugin dept offering Slashdot like “dept.” lines for Blosxom postings.

Supporting Technorati style tag URLs

After releasing the last version of my Blosxom plugin tagging, I noticed that Technorati only seems to like URLs ending in “/tagname” but not ending in “=tagname” (as they do if you use classic query strings instead of the path info), even if the a tag has a rel="tag" attribute. And not only I noticed this but also some other users of the plugin. (Although I do wonder how Furl made it to a Technorati partner with URLs like http://www.furl.net/furled.jsp?topic=tags…)

So I somehow had to change the syntax style for my tags. This wasn’t very hard for the links, but I wanted them to still link to my blog and not to Technorati, Flickr, Wikipedia or any other external resource.

Implementing Technorati style tag URLs

The obviously easiest solution for someone who’s using and administrating Apache web servers for nearly ten years now was to use some mod_voodoo—eh—mod_rewrite:

RewriteEngine On
RewriteRule ^/cgi-bin/blosxom.cgi/tags/(.*)$ /cgi-bin/blosxom.cgi?-tags=$1 [PT]

That way I could use Technorati style tags and had a well performing solution. But somehow this solution wasn’t that satisfying since it wasn’t pure Blosxom and therefore had some dependency including access to some Apache config file. (Even if the config file was called .htaccess. ;-)

A pure Blosxom solution

A few days ago I somehow noticed that in general a special behaviour on some URLs could also be implemented using Blosxom’s API. Using the entries function to modify the Blosxom internal path itself before Blosxom or e.g. the entries_index runs but not returning any hashes, allows to have some path like URLs not being treated as a path by Blosxom.

Unfortunately this couldn’t be incorporated into the tagging plugin itself, since plugins doing such path interpreting voodoo needs to be ran before any plugin supplying an entries function runs. But the tagging plugin must run after such a plugin. So I created the small add-on plugin pathbasedtagging which is solely thought for use together with the tagging plugin (but may have other, yet unknown purposes).

And since I got asked if they could use the tagging plugin to link to external tag URLs instead of the own blog, I included a ready to use list of more or less popular external tag URLs including Technorati, Flickr, del.icio.us, de.lirio.us and Wikipedia.

from the slashdot dept.

Since I’ve always liked the often sarcastic or even evil comments inside Slashdot’s subtitle alike dept. lines and since I’m also used to use them at Symlink, I wanted them in my blog, too. Time for a new plugin.

The basic work of parsing out the data from the text files the posts reside in was already written for the tagging plugin. So I just had to use that code, simplify it and add some little more code to get the dept plugin whose results you can see in my blog directly beneath the title of a posting since a few days now.

Hey, see my Technorati profile: It worked! Technorati recognised the tags! Yeah!

Some new plugins, XFN, Technorati and yigg.de //at 02:09 //by abe

After blathijs and I today talked a little bit about blosxom plugins on the #blosxom IRC channel, I installed the listplugins plugin. Since I’m a perfectionist in some things, I had to configure it to link every plugin I use to it’s web page or source.

While going through my plugin list, I noticed that there were three additional plugins I wrote myself and of which I thought I should share:

• acronyms works similar to and is losely based on Fletcher Penney’s autolinks but instead of setting links it marks configurable keywords as abbreviation or acronym and show their expansion when hovering over the keyword (all using standard XHTML).
• xml_ping_generic is based on xml_ping_weblogs and can ping an arbitrary number of URLs to be pinged with the weblog.com’s XML RPC ping API. By default it pings weblogs.com and technorati.com.
• date_rfc822 is nothing else than the 822-date command (which returns a date in RFC 822 conform format and is written in Perl, too) wrapped into a blosxom plugin. Work similar to date_fullname. I use it for including <pubDate> tags in the RDF.

All plugins are published under the same open source license, they initially came with.
