Hi,

We are a group of students and we working on " Extend OCLParser for Another language (CCSL) ".

we have the project OCL ( Code source OClParser).

but what's the better way for extend OclParser ?

Solution(?) : extend directly the grammar (file .g) OCL and used ANTLR ?

The file .g , is it generated with ecore ?

Thanks for your time. Razz

Hi

You have two options:

The old LPG 2 parser
/org.eclipse.ocl/src/org/eclipse/ocl/parser/EssentialOCL.gi evolved to
be extensible for QVT. It is internally extended for Complete OCL. This
parser in its current form will be deprecated as from Eclipse OCL 3.2
but may be resurrected as a transformation from the new parser.

The new Xtext/ANTLR parser
/org.eclipse.ocl.examples.xtext.essentialocl/src/org/eclipse /ocl/examples/xtext/essentialocl/EssentialOCL.xtext
is extended internally by:

/org.eclipse.ocl.examples.xtext.completeocl/src/org/eclipse/ ocl/examples/xtext/completeocl/CompleteOCL.xtext
/org.eclipse.ocl.examples.xtext.oclinecore/src/org/eclipse/o cl/examples/xtext/oclinecore/OCLinEcore.xtext
/org.eclipse.ocl.examples.xtext.oclstdlib/src/org/eclipse/oc l/examples/xtext/oclstdlib/OCLstdlib.xtext

you should find this a much more promising avenue for extension; and
you get an editor almost for free.

hi Edward,

thank you for your reply.

We find no connection between Meta modele ecore and File .g (grammar)
What is the relation between meta modele ecore and file .g ?

Thank you in advance.

Hi

There are too many *.g files and *.ecore to try to guess which files in
which version of which plugin interest you.

Please express youir question more precisely.

Hi,

the file ocl.g is generated by a Meta modele or hand written ?

Thank.

Hi

There is no ocl.g.

As I wrote before:

"There are too many *.g files and *.ecore to try to guess which files in
which version of which plugin interest you.

Please express youir question more precisely."

i.e. provide the full folder path and version/origin of "ocl.g".

It appears to me that you are probably not using Eclipse OCL.

Hello Ed,

I' continuing the work hardly started by my students...

I have now a working editor of my new grammar based on OCL and generated from Xtext.

As a first test we simply extended the completeOCL.ecore and its xtext grammar.

I still have a problem, and this problem appears even before the introduction of new metaclass in the ecore.

I'm not able to "import" any uml model and to have the completion. Before it was not my priority I didn't care but now, I'd like to finalize this part.

Have you got an OCL file compliant with the CompleteOCL syntax which import a uml or any other model file ?

Consider a simple model where a 'A' class contains some 'B' class instances by using the 'myB' association

I tried this :

import MyImport : 'Simple.uml' 

context A
	inv test:
		self.myB.size() <> 0

What's wrong ?
Thanks in advance !

Regards,

Julien

Hi Julien

The UML support is work in progress.

I had hoped that with the underlying Pivot model being UML-based, that
the UML support would be much easier than the Ecore support. There is
support for pure UML, but any practical UML involves a profile, which is
not yet supported.

I'm hoping to get this in Indigo, but it will be touch and go.

You may be able to workaround the limitations by exporting your UML to
Ecore for now.

/org.eclipse.ocl.examples.xtext.tests/src/org/eclipse/ocl/ex amples/test/xtext/models/RoyalAndLoyal.ocl
(and sibling files) will provide you with an Ecore (and other) examples.

There is no completeOCL.ecore. Did you mean CompleteOCLCST.ecore?

Regards

Ed Willink

Hi Ed !

Sometimes I feel ambitious but I have no real needs to work on uml so I'm going to work on ecore models Rolling Eyes

It's perfect for all my tests. A little point for future readers of this post, I founded the royalandloyal.ocl in

"
/org.eclipse.ocl.examples.project.royalandloyal/oclsrc/RoyalAndLoyal/RoyalAndLoyal.ocl"

Quote:

Exactly ! I planned to make a mix between this metamodel and mine in order to provide a formal temporal extension to OCL.

Thanks for your message.
Good luck with the UML integration.

Regards,

Julien
