Hi

in my DSL I have a statement like the following

'grammar' ePackage=[ecore::EPackage|STRING]

with which I load an EPackage.

now, I'd like to know the java package of the corresponding EMF
generated classes (in particular the package of the generated interfaces).

Thus, for instance, if I write in my program

grammar "mypatch/to/my.ecore"

I'd like to know where the EMF classes corresponding to my.ecore are
generated.

Is there a direct way to achieve this? Or should I go through the
corresponding genmodel? if so, could someone point me to some example on
how to do this please?

many thanks in advance
Lorenzo

Hi Lorenzo,

you have to find the respective genmodel and inspects its values. The
EPackage itself does not know about the (to be) generated artifacts.

Sebastian

thanks

for this purpose it might be enough to look into the same directory
where the EPackage, however, given an EPackage I can't seem to find a
way to get the path of the corresponding ecore... I guess I have to
store that information somewhere else when I load the EPackage, can it be?

cheers
Lorenzo

Alternatively, you could reference (through a URI) the GenModel instance (from the GenModel Ecore meta model) which holds a reference (URI) to the EPackage.

Hi

you mean: instead of loading the .ecore file, load the .genmodel file,
then from there, through GenModel, get a reference to EPackage?

cheers
Lorenzo

By the way, I managed to get a GenModel instance, but I can't seem to
find the information you talk about from GenModel instance...

If you open the .genmodel file in an(y) appropriate editor, then you should a 'foreignModel' element as the first child of the root.

Hi Lorenzo,

have a look at the attributes of the corresponding GenPackage. It should
expose something like base package.

Regards,
Sebastian
