Feedbuilder is a tiny utility that simplifies the process of building and delivering Atom feeds.

Usage

require 'rubygems'
require 'bundler/setup'
require 'feedbuilder'
require 'spec/nug'

nugs = [1, 2, 3].map {|id| Nug.new(id, "Nug #{id}")}
url_builder = FeedBuilder::UrlBuilder.new('http://test.host/', 'http://test.host/nugs')
feed = Nug.build_feed(nugs, url_builder, :feed_title => "Bucket o' nugs") do |nug, entry|
  entry.links << Atom::Link.new(:href => "/nugs/#{nug.id}", :rel => :alternate, :type => 'text/html')
end

# feed.to_xml outputs:

<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
