DSLs or Domain Specific Languages focus on a domain or a particular problem. They serve as an effective human-machine interaction tool as they're highly expressive. Their scope is fairly focused and that keeps them simple and small from the user's point of view. However, designing and implementing DSLs is not easy. Typically this involves steep learning curve and difficult parsing techniques. This is where Groovy comes in. You can take advantage of the flexible syntax of Groovy and it's metaprogramming capability to create what are called internal DSLs, that is, DSLs hosted using a higher level language.

In this fast paced highly interactive presentation you will start out learning the characteristics and types of DSLs. Then you will learn about the challenges in designing DSLs and deep dive into Groovy features that can ease the pain of implementing DSLs. Then, using some live coding, Venkat will show you how to create and implement internal DSLs using Groovy. Along the way you'll learn some tricks to facilitate desirable syntax for your DSL.
