Hello,
Are there any Xtext-based DSLs (tutorials, examples, etc.) which cover targeting non-Java environments? I have a DSL which needs to translated to code which is to run in a C/C++ application with no JVM present, and I was hoping to avoid having to embed a JVM.
The DSL typically looks like this:
entity MyEntity {
name SomeName
handler {
<insert some code here>
}
}
I've been looking at using Xbase, but it seems very heavily tied to JVM execution, and I'm not sure how much work it would be to get it to generate C/C++ code instead.
Worst case I can embed C/C++ code inside a string, but if there is a more elegant solution which allows the user to leverage Xtext features in the embedded code, it would be very nice.
Any ideas?

You can always use Xtext without Xbase and implement the expressions
manually. That's actually a very common usecase. The docs are pretty
clear about the cases where Xbase is applicable. Also, Jan wrote a blog
on that topic recently:
