Good morning,

I want to generate a .qml file from an Ecore model using acceleo, I'm using Eclipse JUNO, I've succeeded in generating different files .h and .cpp but I couldn't manage to find the "property" that's responsible in determining the generated file type (.cpp/ .js/ .qml or any other type).
So, how can I determine the type (extension) of the generated file?)

Thank u in advance ^^

Hi

The external file system is not really part of the model transformation. Consequently many of its characteristics are hidden. The 'correct' solution is to pass filenames as additional input parameters if you really need them. Perhaps Acceleo has some helper functions. You could invoke a Java function.

Hi

Just as with normal functions you can have many arguments, add another if you need one. So in Acceleo I think templates can have manyparameters. Add another one.

I would expect to see it in the launch config, but I don't see parameters there but in the Main java I see

/*
* Add in this list all the arguments used by the starting point of the generation
* If your main template is called on an element of your model and a String, you can
* add in "arguments" this "String" attribute.
*/
so I guess this is what you follow.

Sorry. my Acceleo knowledge is very rusty. I don't use Accelo any more.

Hey,

Another question please, so the java Main that u mentioned! is it a java class/project that I should create within my Acceleo project? or it already exists in my project( even though I cnt find it !)

Kind regards,

Hi

Acceleo auto-creates a Java class with a main that invokes the Accelo support.

Good morning,

So I guess this is the java code, you'll find it below, that I should manipulate in order to get my .qml file ?!

******************************************************************************

/**
* This can be used to launch the generation from a standalone application.
*
* @param args
* Arguments of the generation.
* @generated
*/
public static void main(String[] args) {
try {
if (args.length < 2) {
System.out.println("Arguments not valid : {model, folder}.");
} else {
URI modelURI = URI.createFileURI(args[0]);
File folder = new File(args[1]);

List<String> arguments = new ArrayList<String>();

/*
* If you want to change the content of this method, do NOT forget to change the "@generated"
* tag in the Javadoc of this method to "@generated NOT". Without this new tag, any compilation
* of the Acceleo module with the main template that has caused the creation of this class will
* revert your modifications.
*/

/*
* Add in this list all the arguments used by the starting point of the generation
* If your main template is called on an element of your model and a String, you can
* add in "arguments" this "String" attribute.
*/

Generate generator = new Generate(modelURI, folder, arguments);

/*
* Add the properties from the launch arguments.
* If you want to programmatically add new properties, add them in "propertiesFiles"
* You can add the absolute path of a properties files, or even a project relative path.
* If you want to add another "protocol" for your properties files, please override
* "getPropertiesLoaderService(AcceleoService)" in order to return a new property loader.
* The behavior of the properties loader service is explained in the Acceleo documentation
* (Help -> Help Contents).
*/

for (int i = 2; i < args.length; i++) {
generator.addPropertiesFile(args[i]);
}

generator.doGenerate(new BasicMonitor());
}
} catch (IOException e) {
e.printStackTrace();
}
}
