Hello everybody,

I have developed a DSL. Now I want to embed this DSL in java.
I am new in this concept (Embedding DSL in GPL or java).

Is it possible?
Can I write the code between java codes with my DSL keywords?

Best regards
Parisa

Hi,

To give a better explanation about what I want to do, it's better to say.
I want to have a DSL in which I have the ability of writing java code.

Hi,

so you want to have java like expression inside your dsl?

java: hard to do.
xbase; very easy to do.

have a look at the domain model example or at the seven languages examples (see docs)

Hi Parisa

You can do it using Xbase grammar in your grammar. You can see the process in this link : http://stackoverflow.com/questions/12196448/how-to-include-java-code-block-in-xtext-dsl

Thanks for mentioning that, Christian :)
In the near future, I'm planning to refactoring the plain expression
part to be reusable in other DSLs.

Hi,
is it possible to embed the syntax of a DSL in GPL?
For example here I define a DSL with Xtext and embed this syntax in java.

Hi Christian,

I have thought about it and I think if I embed a Java in DSL and use a reference to Java-Code. It can be vice versa, therefore I can have a Java Code which can refer to DSL-Code.

Actually the implementation must be done with two editors. It's only a solution but it's not a scientific solution.

Regards,
Parisa

Hi Christian,

how can I call java content assistance/ auto completion in DSL text editor in runtime instance of eclipse. Now I have auto completion but I want to open Java auto completion. In which part of forum or in which internet link can I want something about "Call completion engine"?

I have searched a little but I didn't find any code to call it manually.
