Hello everybody,

is there a tutorial or maybe a video or any other ressource, that explains how to start working with sirius starting with nothing? Everything I can find is always based on the basicfamily - example.

Regards
Lars

Hello,

I am not sure to understand the question. Are you looking for tutorials
on how to create a metamodel? That would be more an EMF question. There
are documentations in the Eclipse Help and online
https://www.eclipse.org/modeling/emf/docs/

Regards,
Steve

Hi Steve,

thank you for your answer.

My question was meant as "how to start working with sirius". I do have a ecore modell. All my tries to get Sirius working were futile. I always end up either at the point where classes from my modell are not found (see Screenshot) or when it seems to be working I get only a empty list to select a semantic element from (see second screenshot).

I've cross checked everything that came to mind with the basicfamily example which works just fine. There seems to be nothing important different.

I'm really out of ideas and would like to have a fool proof description on how to get from an ecore modell to a working graphical diagram and editor in sirius.

Regards
Lars

Hi Lars,

In your odesign, on the Viewpoint element "datavault" (child of the root
element), did you fill the "Model File Extension" with the extension of
your models ("datavault" I guess)?
On the Diagram description named datavault diagram, there is a tab
metamodels in the properties view. Is your metamodel registered?
On your node mapping named datavaultNode, the domain class is set as
"datavault.Node"?
Is your metamodel deployed or is it a project in the same Eclipse as
your Viewpoint Specification Project?

Regards,
Steve

Hi Steve,

that was an fast answer! Thanks!

Unfortunately the answer to all but the last of your questions is yes.

My metamodel and my VSP are both projects in the same eclipse.
I already tried and installed the metamodel and the via EMF generated editor to this same eclipse instance (via export and install into host).

I think I've exhausted most ideas that Google could provide Sad

Lars

Hello,

I am not sure if it is properly deployed and know to the registry this
way. Can you try with an Eclipse Runtime? Go to Run/Run Configuration,
add a new Eclipse Application and run it. It will open a new Eclipse
(Runtime) behaving as if the plugin project in the main Eclipse are
installed. In the Eclipse Runtime, import your Viewpoint Specification
Project. This time the metamodel should be properly registered and you
should not have the issues.

Regards,
Steve

Hi Steve,

nothing changed when trying as you suggested.

Because I thought, I've messed something up. I tried again:

- create ecore model
- create MVP based on ecore model
- created minimalistic representations

This time it validates (for now), but then if I create a modelling project and an example file, even with the correct extension, the "Viewpoints Selection" won't show my viewpoint.

I've now spent another two hours trying to work around this. Trying various clues from this forum. To no avail.

I'll give up a this point. In total I've spent 4 or 5 days on sirius now. I'll happily try again should a tutorial or video explaining the start-with-nothing-use-case ever exist...

Thanks for your fast responses though! I really appreciate it.

Regards
Lars

Hi Lars,

Yes, that's unfortunate, you probably have a small issue somewhere in
the registration of your metamodel in your environment, preventing
Sirius to work.
After creating the Ecore model, did you generate the code?
How did you create the example file? Were you able to create it via the
New/Example... wizard? In the Model Explorer view, do you see the
semantic model icon with the "M" decorator and are you able to see to
model element if you expand the tree under the file?

Regards,
Steve

Hi

Perhaps you are hitting
https://bugs.eclipse.org/bugs/show_bug.cgi?id=495611.

Have you Validated your model? the bug suggests that any validation
error may inhibit Siriius.

Did you fix a validation error? the bug suggests that Sirius seems to
remember the error long after the fix. Try a rename.

Regards

Ed Willink

Hello Felix,

If I remember correctly it was an attempt to provide a Class diagram
helping to create your metamodel indeed but that was not completed and
not added to Sirius.

Hi Ed and Steve,

your suggestions sounded promising so I tried it. Thanks! But, I had no success.

Regarding the "Viewpoint not available" issue:
- I did not and don't see the M on my example file.
- I revalidated the model (as I did previously) and made sure nothing comes up.
- I renamed my model example file.
- Additionaly I restarted eclipse at some points - just to be sure.
- still no M.

To answer other questions:

I had previously generated the code for the ecore model.
The model example was not generated by a wizard. I've just now took a look could not find such a wizard. I tried creating it via "Create dynamic instance.." and for another ecore I've imported an existing file. No difference.

It's really not unlikely that I'm missing something basic/essential when working with eclipse, as I'm not really experienced with it.

Regards
Lars

Hi

You need to provide a zipped project so that others can see what you
see. You might find http://wiki.eclipse.org/OCL/ForumNetiquette helpful.

Hi Ed,

I'm really lost here. In my case, what should I provide?

The workspace of my initially started obeo designer?
The workspace of the subsequent started "Run configuration"-instances? (Here are my projects located)
Only some projects of the workspaces in the "Run configuration"-workspaces?
Just Everything?

Could I delete the .plugins directory from .metadata in my archive, because it really inflates the archive?

Hi Lars,

You can provide a zip of your projects (metamodels, edit, editor and
design). You can also zip both worskpace folders to try to reproduce as
close as possible but that might be a big zip depending on your metadata.

Steve

Okay - to be sure I've zipped both workspaces.

- runtime-ValidationError

Contains the case where the odesign can not be validated, because some classes can not be found. Even though they exist and can even be selected by auto completion.

- runtime-ViewpointProblem

Here the validation works, but I can't add my Viewpoint datavaultDSL to the project datavaultDSL.sample in which my example "dvuml"-file is.

Note: The meta model in both (collection of) project are not the same.

I just found this entry:

https://www.eclipse.org/forums/index.php/m/1736069/?srch=selection#msg_1736069

After following what Laurent Fasani suggested, my current problems are gone. At least with another new very simple ecore model. I'll now try with my model.

This is what I had to do:

Quote:

As said in the previous post, a good way is to generate meta model in
your dev eclipse and launch a runtime in which you can:
1- create your modeling project and a an instance of your model(It is
available as your meta model is deployed in your runtime)
2- create a VSP [1]
3- activate the viewpoint on your modeling project

So each time you change your meta model, restart your runtime
In your runtime instance, if you call service[2] in your VSM (odesign)
with service: or aql: interpreter, you can directly test it in your
modeling project even if the VSP plugin is not deployed.

Finally something good happened on an monday morning. Let's see what the week brings Wink

It seems clear that the current ergonomics are such as to drive some new

1) Be a hobbit: https://www.youtube.com/watch?v=G49RUPv5-NU

2) For the elves and dwarves and so on, it would be nice to be able to
start a modeling specification project with a wizard that inputs an
ecore model and creates a small working example, maybe by asking the
user to list 2 or 3 entity classes (rectangles)

That is a pretty nice subject for becoming contributor to the project and that would be greatly appreciated by the user community. Do not hesitate to get in touch with the team through bugzilla (or even mattermost for more direct chat) if you plan to give it shot.

Interestingly you keep asking people to follow a "Forum Netiquette" ( http://wiki.eclipse.org/OCL/ForumNetiquette ) but what you are contributing right now is either noise or passive aggressive wording. Please considers that such statements are easily perceived as disdainful.

Yet again a valid point we'd like to move forward is obfuscated by this noise, and to be honest dampening any will to move forward.

Anyway, if there was an actual actionable point beside the Bug 495611, go ahead..

I can work with Sirius now, including my more elaborate model! I'm looking forward to try interesting stuff. Wink

My problems with getting it running were definitely rooted in my lack of understanding of how eclipse works. Now I finally understand, why the section "Launch a new runtime from your Eclipse" in the Starter Tutorial exists.
