Good/Interesting/Fun examples of Ruby DSL

I've been hearing that coding in Ruby is a real pleasure and namely the fact that one writes a DSL for the problem he's solving. Could anyone provide some fun, interesting or j https://vlc.onl/ ust good code base examples(probably on GitHub). Tweakbox

I am intrigued by the different approach to solve problems. Lately I've been using myself some python and I had this strange feeling that the source just writes itself without any intricacies(looking at you C++) and I remember Ruby.Appvalley

Thanks
