Hello,

is it possible to generate Java code using Epsilon?

Many thanks.

The Epsilon Generation Language (EGL) can be used to produce text from models. That text could be HTML, Java code or anything you want. Could you take a look at this page, and chapter 7 of the Epsilon book?

http://eclipse.org/epsilon/doc/egl/

We have some beautifiers for Java code, but you'd need to write most of the code generation process yourself.

Alternatively, you could use a model-to-model transformation (using the Epsilon Transformation Language, for instance) to produce a model of a Java program according to the MoDisco Java metamodel and then save it to a set of .java files. I think MoDisco provides the model-to-text transformation itself. I haven't tried it myself, but it could be useful for you Smile

Hi Philippe,

In case it helps, Pongo [1] is an example of a non-trivial Java code generator implemented with EGL.

Cheers,

Also incidentally, one of my students did a Java code generator for Hibernate POJOs based on Epsilon:

Hi there,

I was also interested in creating a tool that could generate similar java files (with slightly different constraints), and the examples linked in this discussion are broken links. Are there any examples you could link that I could take a look at as I've had quite the problem finding examples.

Many thanks,
Usman
