= pipe

* http://github.com/drewolson/pipe

== DESCRIPTION:

Pipe lets you aggregate a bunch of RSS feeds based on filters. Tell
pipe the url of the feed, and then give it a hash of xml tag names
plus patterns those tags must fit. Use with sinatra, easy as pie.

== FEATURES/PROBLEMS:

* Create an aggregate RSS feed with filters

== SYNOPSIS:

 Make a new file called ruby_pipe.rb:

  require 'rubygems'
  require 'pipe'
  require 'sinatra'

  get '/' do
    Pipe.create do
      feed "http://news.ycombinator.com/rss", :title => /ruby/i
      feed "http://reddit.com/r/ruby/.rss"
    end
  end

 Now fire up your new pipe:

  ruby ruby_pipe.rb

 Now enjoy some RSS goodness personally tailored to you at
 http://localhost:4567

 We can get a bit more complicated with pipe in a couple ways. First, if you
 have some information in scope that you want your pipe block to close over,
 you can prevent pipe from doing an instance eval by providing a block
 argument. In this case, the block will yield an instance of the Pipe object:

  get '/' do
    url = "http://foo.com/rss"
 
    Pipe.create do |p|
      p.feed url
    end
  end

 You can also tell pipe to combine your filter criteria with "or" logic 
 instead of the default "and" logic:

  get '/' do
    Pipe.create do
      feed "http://www.foo.com/rss",
           :title => /foo/,
           :description => /bar/,
           :combine_with => :or
    end
  end

 Happy piping!
