I want to generate Enums with attributes but I could not figure out how to put the constructor argument expressions to the JvmEnumerationLiterals definitions.

Is there a way to do this with the ModelInferrer or is there another way to do it?

Thanks

if you have a look at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.generateEnumLiteral(JvmEnumerationLiteral, ITreeAppendable, GeneratorConfig)
you can see that it is not yet done.

so please file a bugzilla,

as a workaround you may subclass JvmModelGenerator.

I think there is already a bugzilla for this.

First subclass the JvmModelGenerator class and add something like this:

    override generateEnumLiteral(JvmEnumerationLiteral it, ITreeAppendable appendable, GeneratorConfig config) {
      super.generateEnumLiteral(it, appendable, config)
      compilationStrategy?.apply(appendable)
    }

And then you can do something like this in your inferrer:

element.toEnumerationLiteral("literal name, [		
    initializer = [
      append("(my attribute)")
    ]
]
