Hi,

as I mentioned in an other message I am record my knowledge related to the EMF editor in some new templates to reuse it for new projects.

Now I was thinking about how does the future of code generation look like within EMF?

Is there a EMF editor generator for e4 in development?

Which template engine will be used, the current JET1 seems more or less outdated and I expect stuff what emf.codegen has implemented its own (e.g. merge as far as I understood) is now part of a platform (I didn't take a closer look on all the other M2T projects like Acceleo or Xpand) .

Are there any plans for EMF 3?

Greetings

Stephan

You mean for pure e4 applications (the ones who don't use the backward
support?)

IMHO the best would be to split up the generated code from EMF into 2 parts:
* The pure POJO which holds the UI and only depends on SWT/JFace and
naturally EMF-Core

* The 3.x Framework integration

I'm not aware of any plans and doubt that there are resources available
but naturally I'd happy to help you to get started. How such a single
sourcing / generating approach could work is presented by e4 workbench
model tooling where the same UI-Code runs in:
* Eclipse 4.0 Application Framework
* Eclipse 4.0
* Eclipse > 3.6

Yes I saw your slides from the ESE 2010 on your blog.
I already thought about it to integrate some of the features to my generator. (org.eclipselabs.emf)
Especially because your wrote DI is available on 3.6 too.

What is about the generation itself, is there a replacement for the JET1 and JMerge ?
There are some restriction to extend/change the current generation.

Stephan,

I'm sure there are folks who'd like to sett JET replaced by Acceleo,
Xpand, or JET2, but we don't have immediate plans for those efforts.
It's a lot of work. JMerge is a utility that's reusable independent of
the template language that's used. I expect many folks will keep
reusing it in its current state; it works quite well...

The my hope is/was that one of the other "code generators" have already such a merge feature.

Stephan,

As I said, JMerge is an independent reusable feature so any code
generator can use it. They generally do.

Hi Stephan,

Obeo currently works on Acceleo version of EMF generator. We plan to
release this (at least for the .edit and .editor part) into the EEF
project for June.

Cheers,

Goulwen,

Does this support pure e4?
