Mechanism to get subgenerator name

[adautomendes]

I'm writing some subgenerators and one requirement is to rename the output files based on the subgenerator name, for instance:

generators
      |__ app
      |      |__ templates
      |                |__ myFile
      |__ gen1
      |      |__ templates
      |                |__ myFile
      |__ gen2
            |__ templates
                      |__ myFile

Considering here that 'app' is composed with 'gen1' and 'gen2'. So both will write at my output and I need something like that:

myFile.app
myFile.gen1
myFile.gen2

I know that generators can access 'appname' to get top-level generator name, but what about the subgenerator name? There is any way to get the subgenerator name programmatically at runtime?
