= 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! == REQUIREMENTS: * pipe * hpricot == INSTALL: * gem source -a http://gems.github.com * sudo gem install drewolson-pipe == LICENSE: (The MIT License) Copyright (c) 2008 FIX Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the 'Software'), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
