This is a RadiantCMS extension (originally a behavior by Alessandro Preite Martinez) that adds some tags to fetch and display RSS feeds. It uses the 'ruby-feedparser' module, and it is able to cache the raw feed data and to only fetch the new feed if it has been modified (using the If-Modified-Since HTTP header).

cd RADIANT_APP_ROOT
git clone git://github.com/lorenjohnson/radiant-rss-reader.git vendor/extensions/rss_reader

cd RADIANT_APP_ROOT
git submodule add git://github.com/lorenjohnson/radiant-rss-reader.git vendor/extensions/rss_reader

...then git submodule init and git submodule update as necessary.

Download the tarball from http://github.com/lorenjohnson/radiant-rss-reader/tarball/master into RADIANT_APP_ROOT/vendor/extentions, then:

cd RADIANT_APP_ROOT/vendor/extentions
tar xvzf lorenjohnson-radiant-rss-reader.tgz
mv lorenjohnson-radiant-rss-reader rss_reader

Use it in your page like this (just an example):

<dl>
 <r:feed:items url="http://www.somefeed.com/rss" limit="5">
  <dt><r:feed:link /> - by <r:feed:creator />, <r:feed:date format="%b %d"/></dt>
  <dd><r:feed:content /></dd>
 </r:feed:items>
</dl>

You can also order by some feed entry attribute other than the date:

<ul>

  <r:feed:items
      url="http://feeds.boingboing.net/boingboing/iBag" 
      order="creator ASC">

    <li><r:feed:link /></li>

  </r:feed:items>

</ul>

And you can do headers to mark off sections:

<ul>

  <r:feed:items
      url="http://feeds.boingboing.net/boingboing/iBag" 
      order="creator ASC">

    <r:feed:header for="creator">
      <h2><r:feed:creator /></h2>
    </r:feed:header>

    <li><r:feed:link /></li>

  </r:feed:items>

</ul>

You can sort items and group headers by date, title, content, creator, or link (i.e. the URL of the item). There are more things you can do, which are documented in rss_reader.rb.
