Cross references in DSLs of xtext [message #1240855]

Hi all,
Currently I have 2 DSLs say model1.dsl1 and model2.dsl2.
I am importing model1.dsl1 in model2.dsl2.

So my grammar for import in model2.dsl2 looks like this:

ModelImport: 
	"import" importedNamespace=QualifiedIDWithWildcard
;

QualifiedIDWithWildcard:
	QualifiedID(".*")?
;

QualifiedID:
	ID("."ID)*
;

This works fine if both the .dsl1 and .dsl2 are in same folders.
If my .dsl1 is under "Example" folder i.e. Example/model1.dsl1 and model2.dsl2 is outside Example folder then how the grammar needs to be changed to support this?

Thanks in advance Smile

Hi cross refs is about objects not files.
Imports are for visibility.

If you actually want to crossref adsl stuff from bdsl

P.s. by default it is OK if both files are in the same project or in a referenced project

Hi Christian,
I just want this because I don't want to include namespace in referenced objects always.
i.e. instead of SomeName.a1, SomeName.a2, I will add an import statement which says

import SomeName.*;

and then use a1, a2 and so on directly. But when this SomeName dsl is present in the other folder as explained above, I am not able to refer it, it says it couldn't resolve it.

Regards,
Arshad

Hi,

this will work out of the box if
. you reference the stuff as described in my blog
- have a construct with importedNamespace

so what do you mean with other folder? as i said: if the other folder is in the same project or a referenced project it is fine.
and it will work out of the box.

if not you have to share more detail...
