Cross-cutting in EuGENia / diagram tab caption [message #1831360]

Hi there!

Given that we can break down a diagram into subdiagrams in EuGENia, would there be any way of implementing general cross-cutting?

For example, how could I link an arrow/transition in a diagram to a pre-existing different diagram when double-clicking such an arrow?

I'd also like to know how I could link a diagram tab caption to the subdiagram it shows.

Thank you for your attention.

Regards,

Clever.

Hi Clever,

Eugenia doesn't provide dedicated support for either of these. You'll probably need to modify/extend the generated GMF code to achieve these but that's about as much as I can help with this I'm afraid. I'd suggest posting a question to the GMF forum if you haven't done so already. Given that GMF Tooling is no longer actively maintained, my recommendation would be to also consider alternative options such as Sirius or Picto [1].

Thanks,
Dimitris

Thank you for your reply, Prof. Dimitris!

"Compared to existing graphical modelling frameworks such as Sirius and GMF/Eugenia, the main appeal of Picto is that model visualisation takes place in an embedded browser and therefore you can leverage any HTML/SVG/JavaScript-based technology such as D3.js, mxGraph and JointJS." => Picto's main appeal doesn't apply to my case...

"Picto displays read-only views of models and as such it is not a good fit if diagram-based model editing capabilities are required" => It sounds to limit my application...

I tried Sirius before EuGENia, and the latter proved to be much more effective and easier to use. Is EuGENia still up and running, i.e., counting on further development?

Regards,

Clever.

Hi Clever,

Eugenia is in maintenance mode at the moment. We're responding to queries and we'll keep fixing bugs but we have no plans to develop it further.

Thanks,
Dimitris

This is really bad news, Prof. Dimitris! EuGENia is an amazing tool and counts on your great support!

In this case, migrating into Picto doesn't really sound like an option after all...In addition to the aforementioned URL, would you suggest other online resources for newbie developers?

Thank you for your attention.

Regards,

Clever.

Hi Clever,

Eugenia is quite feature-complete and with its support for polishing transformations [1] you can use it to implement any editor you can implement with pure GMF. Adding more features would be mostly a matter of encapsulating common polishing transformations into first-class annotations, which we haven't seen much demand for. Resource-wise, beyond the articles in [2], GitHub search returns more than 800 examples of Ecore metamodels annotated with Eugenia annotations [3] which you could use for inspiration.

Thanks,
Dimitris
