Domain specific languages (DSL) are an incredibly powerful tool for making it easier to program or configure complex systems. They are also everywhere – as a software engineer you are most likely using several different DSLs on a daily basis.
In this article, you will learn what domain specific languages are, when they should be used, and finally how you can make your very own DSL in Ruby using advanced metaprogramming techniques.
This article builds upon Nikola Todorovic’s introduction to Ruby metaprogramming, also published on the Toptal Blog. So if you are new to metaprogramming, make sure you read that first.
