[news.eclipse.modeling.gmt] Re: [Epsilon] Configuring HUTN file

[Louis Rose <louis@xxxxxxxxxxxxx>]

Hi Pau,

Many thanks for your message. Apologies for the late reply; I had a 
deadline yesterday.

To use the HUTN configuration metamodel, you should:

1) Create a new instance of the metamodel. In the Epsilon perspective, 
Click File | New | EMF Model. Select: 
"http://www.eclipse.org/gmt/epsilon/hutnConfig"; as the Metamodel URI, 
and "Configuration" as the root instance type.

2) Open the new model, and define your rules with tree-structure editor.

3) In your HUTN source file, specify the config file in the same block 
as the metamodel nsURI. For example:

 @Spec {
	MetaModel "FamiliesMetaModel" {
		nsUri = "http://www.example.org/families";
		configFile = "FamiliesConfig.model"
	}
}

The value of "configFile" is relative to the HUTN source.

4) Save the HUTN source, and your configuration file should be loaded.

Does this fix your problem?

(On a related note, we do not yet support embedded configuration, as you 
describe. This seems to be a sensible alternative to the method outlined 
above, and is mentioned in the HUTN specification. I will add it to the 
list of features to be implemented in the next iteration (later this month).

Many thanks,
Louis.
