MF: Whenever we talk about the pros and cons of DSL usage, I always stress that a DSL is nothing more than a thin veneer over a library or framework (which we refer to as a Semantic Model). InfoQ: What are the benefits of using DSLs and when would you prefer internal or rather leverage external DSLs? Their embrace of DSLs seems to be a dying movement grasping at straws to retain some fragments of respectability.

This is the CASE heritage which correlates with the OMG's MDA. For this group, there's a good synergy with DSLs because DSLs are a good way of expressing models that describe alternative computational models (which I refer to as Adaptive Models in the book).īut there's the other strain of MDSD, those who think diagrams should be worth a thousand lines of code. There are those who are focused on a well defined semantic model that's used to drive computation. I've not kept a close eye on the MDSD community, but it seems to have some quite distinct strains within it. MF: This is a difficult question to tackle.

InfoQ: Where is the boundary between MDSD (Model-Driven Software Development) and DSLs? This way we'll have a better chance of seeing what their true potential is. My hope for this book is that it collects together these techniques and thus makes it easier for people to explore DSLs. MF: In my travels I saw quite a few DSLs built in projects, but I think they missed some good ideas because it was too hard to find information about the various techniques you can use to build a DSL. This book attempts to allay the fears people have around creating languages, with the hope that we’ll start to see some interesting and effective new uses of DSLs. RJP: There is a lack of understanding of DSLs, their uses, and the tools and techniques needed to implement them. InfoQ: What is the main message you like your readers to grasp? InfoQ could interview Martin (MF) and Rebecca (RJP) to get the motivation and rationale for writing a book on this emerging topic: “Domain-Specific Languages” does not only address the concepts behind DSLs, but also tries to explain the subject in a pragmatic manner using examples in Java, C# and other languages.The book contains different patterns that reveal best practices in designing DSLs.

No matter what category developers are using, it is essential to build any DSL on top of a sound semantic model as the authors keep emphasizing. The third category, Language Workbenches, represent custom environments for editing and creating DSLs. The book introduces the category of external DSLs which are different from the main programming languages used, and internal DSLs that are hosted by the underlying programming language like Ruby on Rails.

Wherever possible, chapters are organized to be self-standing, and most reference topics are presented in a familiar patterns format.Īrmed with this wide-ranging book, developers will have the knowledge they need to make important decisions about DSLs-and, where appropriate, gain the significant technical and business benefits they offer.Architecting Your Journey to Cloud-Native with AWS This book’s techniques may be utilized with most modern object-oriented languages the author provides numerous examples in Java and C#, as well as selected examples in Ruby. Then, where DSLs prove suitable, Fowler presents effective techniques for building them, and guides software engineers in choosing the right approaches for their applications. In Domain-Specific Languages, noted software development expert Martin Fowler first provides the information software professionals need to decide if and when to utilize DSLs. When carefully selected and used, Domain-Specific Languages (DSLs) may simplify complex code, promote effective communication with customers, improve productivity, and unclog development bottlenecks.
