I’m trying to port the rss behavior to an extension for use in mental. I can’t find anything talking about how to develop extensions, so I’m baseing this off looking at hello\_tag example. I’ve created two files: rss\_reader\_extension.rb that looks like this: [http://pastie.caboo.se/34525](http://pastie.caboo.se/34525) and lib/rss\_reader.lib: [http://pastie.caboo.se/34529](http://pastie.caboo.se/34529) ---

Sorry, accidentally hit send (I’ve gone brain dead looking for stuff on extensions). Anyway, this is obviously not working, but I have no idea where to go from here. Can anyone jump in and help here? I’m not sure what has changed from the old system to the new, so I have no idea what I need to change. Thanks, BJ Clark ---

When I created an extension I followed this blog post: [http://radiantcms.org/blog/2006/11/24/how-to-write-time-sensitive-or-expiring-content/](http://radiantcms.org/blog/2006/11/24/how-to-write-time-sensitive-or-expiring-content/) and it worked for me. ---

What, if anything is happening? Put some print statements into your rss\_reader\_extension file to show if it’s being loaded. Have you put your extensions files under vendor/extensions/rss\_reader ? ---

BJ and I worked through the issues on this over IRC today and cleaned everything up into an acceptable port to extension. He’ll be doing officially announcing and offering it up on the group today or tomorrow.

BJ, If we can meet on IRC today or tomorrow we could maybe work on this together. I was planning on porting the RSS behavior this week anyway so I can convert one of our sites that needs it but also needs to go Mental. I’ll get on the #radiantcms IRC channel at 2:30 PM MST and hang-out there until 5ish. Let me know if you want to setup something for tomorrow instead. Loren
