This language will be understood by developers, domain experts, and also by the software, which will be able to execute the instructions specified in the DSL. domain specific language (DSL): A domain specific language (DSL) is a programming language that is developed to meet a specific need. Un domain-specific language (in acronimo DSL), in italiano linguaggio di dominio specifico nello sviluppo software e nell'ingegneria di dominio è un linguaggio di programmazione o un linguaggio di specifica dedicato a particolari problemi di un dominio, a una particolare tecnica di rappresentazione e/o a una particolare soluzione tecnica. You could also take a look at this explanation of projectional editing written by Martin Fowler. In the meantime, the browsers have been completely rewritten multiple times, but the logic can be ported to new technologies. Now, I should probably just praise this book and stress how much I have enjoyed it. However, if you find internal DSLs as irrelevant as I do, you may be interested in only some portions of this book. You will have a hard time finding an exploration of these topics at this level of detail anywhere else. Plus, they misspelled my name (-1 point for that). All built on one platform. It is more academic stuff than an industrial-grade language workbench, so I would suggest a bit of caution. Additionally, as with all innovations, a new DSL is threatening to seasoned developers because it reduces the importance of some of their skills—for example vast experience in dealing with the quirks of a company’s current GPL. I’ve had the occasion to work with Markus, and he is simply the best in this field, so if you can learn something from him, do it. You would need to communicate with the engineers to understand how to control the brakes. Aside from the practical benefits, I find the topic extremely fascinating. An HTML page written 20 years ago can still be opened using devices that no one was able to imagine 20 years ago. You may want to check out this list of projects implemented with Xtext to get an idea of what is possible to achieve using Xtext. Yacc, Bison and ANTLR are examples of executable variations of BNF DSL. What I like about this book is that it is not a reference manual, but it contains indications and opinions on topics like Scoping or building typesystem rules (the author has significant experience in this specific topic). I want to share a story about a company I worked with. Domain Specific Languages (DSLs) are limited forms of computer language designed for a specific class of problems. Think about the time spent reasoning about deallocating memory or choosing which implementation of a list would perform best for the case at hand. The editors generated by Xtext can be deeply customized, if you know what you are doing. It is a language used to define how to insert, modify, or extract data from a relational database. the chapter “The Structure Aspect” or “Structure In Practice”). A typical example is spreadsheet programming using the Excel macro-language. And of course, they are thoughtful and well explained, as you would expect from Martin Fowler. They are safer. I remember the long days reading the EMF book as one of the most mind-numbingly boring experiences I have ever had. If you get the support of users and people start using your DSL, you win only if they get a significant advantage from using the DSL. Domain logic is what has value and should be preserved, while technology changes over time. We can teach them more easily: they are limited in scope so less time and less training are needed to master them, simply because there is less stuff to study.
