Generation oddity with imported grammar [message #59618]

Hi,

I get a strange generation error with already generated packages from
imported grammar duplicated in dependent grammar project src-gen.

context :

-----------------------------------
grammar A with Terminals

TopA :
(xyzs+=XYZ)+
;

XYZ :
'xyz' name=ID ';'
;
-----------------------------------

-----------------------------------
grammar B with A
import "http://www.sf.net/ABC"
// ABC package URI as declared in A/plugin.xml resolve XYZ right !

TopB :
(imports+=IMPORT)+
(links+=LINK)+
;

IMPORT:
'import' uri=STRING ';'
;

LINK :
' link' name=ID 'to' refXYZ=[XYZ] ';' // from A
;
-----------------------------------

question :

*) http:// protocol URI for imported package pb ?

strange behavior : already generated packages from imported grammar A are
duplicated in dependent grammar B project src-gen directory.

When looking at B.genmodel something say 'http://sourceforge.net/ABC' not
found.

Pb is : I declared "http://www.sf.net/ABC" and tried to import accordingly
... !

Should generated_package extension IDs like 'http://...' should be avoided
?

Is it a bug ?

Is it working as it should ?

regards,

Hi Lucas,

did set the reference to the existing genModels in your
EcoreGeneratorFragment?
Please have a look at the docs for details about it (or search this
newsgroup for "genModels".

http://www.eclipse.org/Xtext/documentation/0_7_0/xtext.html (search for
genModels

Regards,
Sebastian

in this doc 'platform:' should be read 'platform:/resource'

just realized after reading the excellent article from M. Paternostro :

Solution working for me :

------------------------------------------
Adding a package import in B.xtext

import "http://www.sf.net/A/XYZ"
-------------------------------------------------------

Adding a new bean in GenerateDSL.mwe :

<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup"
platformUri="${runtimeProject}/../project/src-gen">
<registerGeneratedEPackage value="net.sf.A.XYZPackage"/>
</bean>

And modifying EcoreGeneratorFragment fragment :

<fragment
class="org.eclipse.xtext.generator.ecore.EcoreGeneratorFragment "

genModels=" platform:/resource/project/src-gen/net/sf/xqz/engine/script/ Orchestror.genmodel "
/>

Et voila !

Hi Lucas,

I've searched the docs for platform: but could not spot the mistake. Can
you give me a hint as I'ld like to fix it.

Sebastian
