Feedbag is Ruby's favorite auto-discovery tool/library!
>> require "feedbag" => true >> Feedbag.find "damog.net/blog" => ["http://damog.net/blog/atom.xml"] >> Feedbag.feed? "perl.org" => false >> Feedbag.feed?("https://m.signalvnoise.com/feed") => true
$ gem install feedbag
Or just grab feedbag.rb and use it on your own project:
$ wget https://raw.githubusercontent.com/damog/feedbag/master/lib/feedbag.rb
You can also use the command line tool for quick queries, if you install the gem:
» feedbag https://www.ruby-lang.org/en/ == https://www.ruby-lang.org/en/: - https://www.ruby-lang.org/en/feeds/news.rss
Why should you use it?
- Because it only uses Nokogiri as dependency.
- Because it follows modern feed filename conventions (like those ones used by WordPress blogs, or Blogger, etc).
- Because it's a single file you can embed easily in your application.
- Because it's faster than anything else.
This is and will always be free software. See COPYING for more information.
