How to force hawk to follow package structure [message #1841003]

Hi

I'm using hawk as a source model in a transformation. I facing a difference between how 'plain' epsilon source model works and hawk as source model.

The example in attachment shows illustrates my problem. The rule definition:

rule aRule transform s: IN!company::Company to t : OUT!companyTab::CompanyTab {
	t.col1 = s.name + "_transformed_" + s.isHeadquarter;
}

works fine in plain epsilon, but not with hawk. If change 's: IN!company::Company' to 's: IN!Company' it works in both cases. Now, the first FQN complies with the model definition, hence I would expect to also work in hawk. Maybe I'm missing something...

Thank you for your help and kind regards

Hi Jo,

Yes, when using the `A::B` notation, Hawk currently only allows straight metamodel URIs to be used for `A` (for instance, `https://www.home.org/companyTab::CompanyTab` would work).

I'll see if we can make it so `packageName::type` also works.

Best,
Antonio

Hi Jo,

No problem. I've got a merge request with the enhancement ready:

https://gitlab.eclipse.org/eclipse/hawk/hawk/-/merge_requests/8

Once it passes all tests, I'll merge it. It should be available within a few hours :-).

Best,
Antonio
