Problems with imports inside textmodels [message #50800]

Hi there,

we want to use simple text imports inside text models. Our xtext
definition for that is:

Import : 'import' importedURI=STRING ';';

Umfortunately this doesn't work. If we copy the elements from the imported
file into the base file it works. Here an example:

The grammar:
grammar org.xtext.example.ProblemDSL with
org.eclipse.xtext.common.Terminals

generate problemDSL "http://www.xtext.org/example/ProblemDSL"

Model :
(imports+=Import)*
(exdeus+=Exdeus)*
(refs+=Reference)*;

Import :
'import' importedURI=STRING ';';

Exdeus :
'exdeus' name=ID ';';

Reference :
'ref' name=[Exdeus] ';';

The base model file:
import "MyModel2.psdl";

ref foo;

The imported model file "MyModel2.psdl":
exdeus foo;

The template file is as follows:
«IMPORT problemDSL»;

«DEFINE main FOR Model-»
«FILE "output.txt"»
«EXPAND exdeus FOREACH exdeus»
«EXPAND reference FOREACH refs»
«ENDFILE»
«ENDDEFINE»

«DEFINE exdeus FOR Exdeus»
Exdeus «name»
«ENDDEFINE»

«DEFINE reference FOR Reference»
Reference «name»
«ENDDEFINE»

This in combination throws the following error message:
2101 [main] ERROR eclipse.emf.mwe.core.WorkflowRunner - [ERROR]:
classpath:/model/MyModel.pdsl(3): Couldn't resolve reference to Exdeus
foo(Element: -UNKNOWN-; Reported by: MweReader: loading file from
classpath:/model/MyModel.pdsl)

Hi Steffen,

please try something like

Import :
'import' importURI=STRING;

Regards,
Sebastian

Hi Steffen,

as Sebastian said it's importURI not importedURI.
I've found the missleading occurence in the documentation and have fixed
it. Thanks for the feedback.
