Feedbag is Ruby's favorite auto-discovery tool/library!

Quick synopsis

>> 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:

ยป 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.
