Importing a grammar which inturn has imported a Metamodel [message #50739] Fri, 12 June 2009 13:12 Go to next message
Eclipse UserFriend
Hello All

I am tryin to write a grammar(say gr_1) that has imported another
Grammar(gr_2).
However gr_2 has also imported Metamodel say m_1.

So does using rules of gr_1 in gr_2 valid in the XText?

->Moreover I have suppressed the generation of Metamodel in gr_1.

Can't get it working!!

My implm is somewhat like this:
------------------------------gr_2-----------------------

grammar org.xtext.example.MyDsl4 with org.xtext.samm_dsl.Edifice

generate myDsl4 "http://www.xtext.org/example/MyDsl4"

Core:
('Entity:'core_elem+=MemoryDescriptor)*
;
..
..
------------------------------------
---------------------------gr_1----------------------------- ----

grammar org.xtext.samm_dsl.Edifice with org.eclipse.xtext.common.Terminals

import "http://www.eclipse.org/emf/2002/Ecore" as ecore



import "http://q-impress.eu/samm/core" as refn_core
import "http://q-impress.eu/samm/datatype" as refn_datatypes
import "http://q-impress.eu/samm/deployment/targetenvironment" as
refn_depl_targetenv
import "http://q-impress.eu/samm/deployment/hardware" as refn_depl_hardware
import "http://q-impress.eu/samm/deployment/allocation" as
refn_depl_allocation
import "http://q-impress.eu/samm/behaviour" as refn_behaviour
import "http://q-impress.eu/samm/usagemodel" as refn_usagemodel
import "http://q-impress.eu/samm/staticstructure" as refn_staticstructure

import "http://q-impress.eu/identifier" as ident



Identifier returns ident::Identifier :
Entity;

//This part pertains to Core classes
Entity returns refn_core::Entity:
(NamedEntity | Connector | EndPoint | HardwareDescriptor)
;

..
..

MemoryDescriptor returns refn_depl_hardware::MemoryDescriptor:
'MemoryDescriptor' 'id:' id=STRING '{'
//parent attrib(s)
'doc:' documentation=STRING';'

//class specific attributes
'bw:' bandwidth=INT ';'
'fsbFreq:' fsbFrequency=INT ';'
'accessFreq:' accessLatency=INT ';'
'burstLen:' burstLength=INT ';'
'}'

;

I specified my grammar wrongly in my previous post.(just interchanged)
Sry. consider this..

I am tryin to write a grammar(say gr_1) that has imported another
Grammar(gr_2).
However gr_2 has also imported Metamodel say m_1.

So is using rules of gr_2 in gr_1 valid this way in the XText?

->Moreover I have suppressed the generation of Metamodel in gr_2.

Can't get it working!!

My implm is somewhat like this:

Hi Durga,

please attach your mwe-file. I assume that you did not register your
imported metamodels in your workflow.
Thanks.

I indeed registered the generated EPackages in the mwe file.

But the problem I guess is the inavailability of the following packages:

org.xtext.samm_dsl.edifice
org.xtext.samm_dsl.edifice.util
org.xtext.samm_dsl.edifice.impl

----------------------------------------------

But these packages are indeed not intended to be generated Since, I've
suppressed the generation of ecore model for the edifice dsl.(gr_2)

Thanks.

Hello Sebastian

I'm really sry but I must say that the error I get is when I run the
workflow for gr_1( not gr_2).

I messed up the order of grammars!! sry..

Thanks.

Hi Durga,

I guess you did not suppress ecore-generation in the workflow file, that
finally fails with the exception trace that you posted originally.

Please try to establish references to the genmodels of the metamodels
that were imported in your base language. It can be done similar to the
following snippet:

<fragment class="org.eclipse.xtext.generator.ecore.EcoreGeneratorFragment ">
<genmodels
value="platform:/resource/dontknowthepath/metamodel1.genmodel,
platform:/resource/whateverpath/metamodel2.genmodel"/>
</fragment>

Hope that helps,
Sebastian
