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:
