News, guides, tutorials and the bigger picture of creating domain specific languages
We were lucky enough to get an interview from Pedro J. Molina. He has been a well-known protagonist in the Language Engineering field for quite some time. For me it was such an honor to finally meet him, even if virtually. In this interview he tells us about his experience using DSLs, his activities at […]
There are many uses for Code Generation: We can generate repetitive code from schemas or source of information we have. For example, we can generate Data Access Objects from database schema files We can generate code from wizards We can generate skeletons of applications from simple models. We wrote about an example here: Code Generation […]
Excel is a great software but… for some tasks is just not the right tool. In this article we share a story of how Excel ended up costing billions of dollars because of a simple error. Luckily there is none in your spreadsheets 🙂 We all know how this happens: you start creating a short list […]
This guide will show you: the what: after a definition we will look into 19 examples of DSLs the why: what are the concrete benefits you can achieve using DSLs the how: we will discuss the different ways to build a DSLs and what are the success factors After that you will get a list […]
When building a language there is one aspect which is absolutely crucial: that is tool support. Tool support will determine if your language is usable at all, it will influence the reception from user and the usability. In this video I explain why and how you can build great tool support with a limited effort. […]
Recently I answered this question on quora. I thought it could be useful to report the answer here, in case someone else is looking for books about Domain Specific Languages. What are good books on best practices of the design of domain-specific languages (DSL)? On one side you have internal DSLs: they are sort of […]
Jan Köhnlein is a leading expert in DSL design and an Xtext committer. After obtaining his PhD from the Technical University of Hamburg he worked for companies very well known in the modeling field: Gentleware and Itemis. Recently he founded TypeFox together with Sven Efftinge and Moritz Eysholdt. I thought it was a good moment […]
A far-fetched goal I have is using sketching on a whiteboard as a way to define programs. I mean formal programs that you can execute. Of course through your sketches you would define programs in a high level domain specific language, for example describing a state machine or an Entity-Relationship diagram. To do so I […]
There are different possible notations for languages: textual and graphical are the two larger families. We can define graphical notations for formal languages. For example we can define a graphical notation to define state machines. A Domain Specific Language for state machines can be defined using JetBrains MPS. However the user would have to edit […]
I am blessed (or cursed) with having many different interests in software development. However my deepest love is with language engineering. There are different tools and techniques but Jetbrains MPS is particularly fascinating. To help people getting started or just get the feeling of how it is to develop with Jetbrains MPS I recorded this short screencast. […]
