He presented XTend, a language on the JVM that is build with XText and which compiles to java source code. After a walkthrough he shows with an example how easy it is to build a DSL with XText. The whole presentation was done by showing code! In my opinion the best way and he did a great job in answering questions.
What differenciates XTend from the varios JVM languages like groovy, scala, kotlin etc.? It does not need it´s own bytecode compile since XTend it translated at compile time to java source code. In that way XTend can be seen as “syntactic sugar” for java - or a domain specific language. (writing java code without the boilerplate)
It was a great meetup with some really good discussions in the end! Looking forward for the upcoming meeting in June!
