[TCS] Examples that convert .tcs file to model [message #17718]

Hi, sorry if I've used the wrong group for this question.

I'm looking for any working example that converts a source .tcs file into
a TCS conformant model file. I'd also be interested to know whether TCS is
good choice for converting from models to concrete text (I won't need to
go from text to model), or should I use another approach?

Maybe this question would be better asked on the GMT newsgroup, which
I've added to the "to" list.

I have added an example here:
http://www.eclipse.org/gmt/am3/tcs/download/TCSInjector.zip
Also reachable from here: http://wiki.eclipse.org/index.php/TCS

I'd also be interested to know whether

Yes, TCS provides you a bridge between models and concrete text (text to
model and model to text).

Hope this help ;-)

Regards,
Freddy.

Thanks for this sample Freddy, it works fine.

I've extended my project copy by defining a metamodel for the AddressBook
by handcrafting an AddressBook.km3 (reverse-engineered from the
AddressBook.tcs, is there a more clever way to produce the metamodel?).
I've then successfully extracted a model file (AddressBook1.ecore) to a
text file (AddressBook1.out) using the ant task am3.saveModel (with
extractor embedded element).

I then tried to transform the text file back to a model file using the
am3.loadModel with injector approach, but without success as follows:

<target name="text2model" depends="loadModels">
<am3.loadModel modelHandler="EMF" name="M" metamodel="AddressBook.tcs"
path="${path}output/AddressBook1.out">
<injector name="ebnf">
<param name="name" value="TCS"/>
<classpath>
<pathelement location="${path}TCS/TCS-importer.jar" />
</classpath>
</injector>
</am3.loadModel>

<am3.saveModel model="M"
path="${path}output/GeneratedAddressBook1.ecore"/>
</target>

... where metamodel AddressBook.tcs is defined to be the
AddressBook.tcs.ecore file.

When I execute this I get:
text2model:
[am3.loadModel] Loading of model M
[am3.loadModel] no type named 'ConcreteSyntax' in metamodel
'AddressBook.tcs'
[am3.loadModel] java.lang.NullPointerException
[am3.loadModel] at
org.atl.engine.repositories.emf4atl.ASMEMFModel.newModelElem ent(ASMEMFModel.java:206)
[am3.loadModel] at
org.atl.engine.vm.nativelib.ASMModel.newModelElement(ASMMode l.java:74)
[am3.loadModel] at
org.atl.engine.vm.nativelib.ASMModel.newModelElement(ASMMode l.java:62)
(stack continues...)

I've examined the AddressBook.tcs.ecore and it does contain the
ConcreteSyntax type, so I'm a bit confused.

Again, any help would be greatly appreciated.

Thanks
Paul

You could define your metamodel directly in KM3 (which is a Domain
Specific Language or DSL for defining metamodels) and then automatically
transform it into other formats such as Ecore for example.

I think the error comes from the value of the "metamodel" parameter of
the am3.loadModel task. For instance, it may be metamodel="AddressBook"
if you already have loaded the AddressBook metamodel like this:
<am3.loadModel modelHandler="EMF" name="AddressBook" metamodel="MOF"
path="AddressBook.ecore" />

Hugo,

Thanks for your reply. Unfortunately changing the metamodel as you
suggested has resulted in the same type of error (no type named
'ConcreteSyntax' in metamodel 'AddressBook').
I suspect the injector is expecting to find the TCS metamodel. If that's
the case then I wonder how I can load a text file using my metamodel.

The normal process is to create first your metamodel ;-)

In this case (text to model), you will need to generate and to use a
"specific" AddressBook injector (i.e. AddressBook-importer.jar).

I have created a complete TCS use case for AddressBook available here:
http://www.eclipse.org/gmt/am3/tcs/download/TCSSample.zip

And I have also started a tutorial:
http://wiki.eclipse.org/index.php/TCS/TCS_Toolkit_Tutorial

For the moment, this wiki page is only a stub. But I hope this can help
you :-)

Regards,
Freddy.
