Working example of Xtext and XBase [message #1666113] Wed, 11 March 2015 14:50 Go to next message

Hello

I am looking for a working example that uses Xtext and Xbase, to have some Java-like expressions in my DSLs.

There are some examples out there from the examples of the Book on GitHub. But, they do not compile with Xtext 2.8.0.v201503090534. I managed to compile them via Xtext 2.7.3, but when I execute the language, I get the following exception.

What are rather easy ways of having some Java-like languages with Xtext? I have seen there is a SmallJava example in book, but there is no code generation for it...

Hi,

have a look at the domain model example that ships with xtext.

btw: if you use xbase you ususally do not with a generator yourself (JvmModelGenerator) is used instead - which is leveraged through the JvmModelInferrer

Hi

I still have to update the examples of the book to Xtext 2.8.0, I will
do that in the next few days. The Xbase example won't compile with
Xtext 2.8.0 because Xtext artifacts have to be regenerated, by running
the mwe2 workflow.

cheers
Lorenzo
