Hi all,
As defined in the title, I try to add "just" a temporal operator "always"
in the MDT/OCL.
I add it in the EssentialOCL xtext grammar
EssentialOCLPrefixOperator:
'-' | 'not'
| 'always';
but when I try to write some constraints,
I has this error "Unresolved Operation 'Boolean::always()'"
I find that I should extend oclstdlib, pivot, etc.
but I don't know the order of changes.
what are the several steps?
Best regards,
Fy Za

Hi Ed,
I succeeded to extend CompleteOCL with always operator (as you said, I should follow the 'not' operator).
However, my extension was defined in the code level. I edit some classes like for example org.eclipse.ocl.examples.library.oclstdlib.OCLstdlibTables.java.
However, when I try to generate this class with some modifications defined in the OCL-2.4.oclstdlib using org.eclipse.ocl.examples.codegen.tables.model2tables.mtl,
I have many errors in org.eclipse.ocl.examples.library.oclstdlib.OCLstdlibTables.java.
.
What is the element that should be clicked to run the model2tables.mtl? the OCL-2.4.oclstdlib file? or all the package?
I 'd like to know if I should use this model2tables.mtl directly or using a mwe2 workflow ?
Best regards,

Extending the OCL grammars is possible, but not supported; no tutorials etc.
Since you are extending with something very similar to 'not' you can
search out/step through resolution of a not expression.

Hi
In principle you can just do GenerateAll but it has a registration bug.
I think
Generate OCLstdlib model,
Generate Pivot Models,
Generate Xtext Models,
Generate All Editors
can be run in any order; probably better to run Generate Xtext Models
before Generate All Editors (or just one of the editors).

Hi
The CST is Xtext friendly. Just save the Xtext resource.
The AST is OMG-defined.
Try looking at the examples/Junit tests.
