creating a RULE just to rename a ClassUNIT [message #1421444]

Hello,

i'm new to ATL so sorry for any dumb questions. First let me contextualize what I like to do. I'm working with an instance of the KDM, which was generated by MODisco. I would like to use this instance of KDM and create a rule in ATL to rename an specifies ClassUnit. I tried the code below. But the this code runs and creates a separate ClassUnit excluding all other elements of the KDM.


-- @nsURI MM=http://www.eclipse.org/MoDisco/kdm/code
-- @nsURI MM1=http://www.eclipse.org/MoDisco/kdm/code

module teste;
create OUT : MM1 from IN : MM;

rule renameClass { 
	from
		s : MM!ClassUnit (s.name = 'Client')
	using {
	newName : String = 'newName';
}	
		to 
		t : MM1!ClassUnit (
			name <- newName
		)

}

Does anyone know how to rename a element (ClassUnit) and just keep the other without change after the transformation?

Could you show me a basic example?

Thank you so much.

Sounds like you want to use refining mode:

The metamodels have to be the same for the input and output model:

create OUT : MM refining IN : MM;

Cheers,
Dennis

Hello Dennis, I did what you told me but it didn't work. When I put -- @atlcompiler emftvm on the ATL file I get I error saying "Errors occurred during the build.". I don't know what to do anymore, can you please send me a basic example of "refining model" with ATL, that would be great.

Thank you.

Dennis I made the followings steps, but it didn't work......

1 - I installed ATL/EMFTVM..
2 - Then I put -- @atlcompiler emftvm on the head of my ATL file, but it always get an error..
3 - Then I set up the ATL/EMFTVM launch as shown in the attached picture
4 - Then when I ask it to run I get the following message "org.eclipse.m2m.atl.emftvm.util.VMException: Error during module loading: Module rename not found"

[code]
-- @atlcompiler emftvm
-- @nsURI MM=http://www.eclipse.org/MoDisco/kdm/code

module rename;
create OUT : MM refining IN : MM;

rule renameClass {
from
s : MM!ClassUnit (s.name = 'Client')
using {
newName : String = 'newName';
}
to
t : MM!ClassUnit (
name <- newName
)

}
[\code]

Does I need to use the -- @atlcompiler emftvm???

Thanks

You don't have to use EMFTVM per sé, but it should definitely work. Unfortunately, I cannot see your attachment with the launch config. I've attached a zipped test Eclipse project that shows how to use EMFTVM for this scenario. Let me know if that works for you!
