Ruby on Rails Custom Generators with multiple sub generators

Question

Hi I was trying to generate a custom generator, So my here my custom generators is Myinitializer, which has myinitializer inside it. But I wanted to have more generators inside it, like the Rails and TestUnit has. I went thought https://guides.rubyonrails.org/generators.html but i could not find how to create these sub generators or whatever they are called. I tried creating a new file inside the generated directory (/lib/generator/myinitializer) but it does not do the sub generator thing.

rails -g

Rails:
  application_record
  assets
  channel
  ...
  system_test
  task

ActiveRecord:
  active_record:application_record

Myinitializer:
  myinitializer


TestUnit:
  test_unit:channel
  test_unit:generator
  test_unit:mailbox
  test_unit:plugin

So what i wanted to have something like:

MyInitializer:
  myinitializer
  anothergeneratorhere

What rmlockerd explained only half answered my question, Here's what worked:

I created the custom generators using rails g generator g1 and rails g generator g2 and organized them into the following directory structure:

# directory: /lib/generators
λ tree
.
└── gorking_generators
    ├── g1
    │   ├── g1_generator.rb
    │   ├── templates
    │   └── USAGE
    └── g2
        ├── g2_generator.rb
        ├── templates
        └── USAGE

The content of the files are as follows:

# file: g1_generator.rb
module GorkingGenerators
  module Generators
    class G1Generator < Rails::Generators::NamedBase
      source_root File.expand_path('templates', __dir__)
    end
  end
end
# file: g2_generator.rb
module GorkingGenerators
  module Generators
    class G2Generator < Rails::Generators::NamedBase
      source_root File.expand_path('templates', __dir__)
    end
  end
end

After this, I am able to see the generators in place when using rails g:

GorkingGenerators:
  gorking_generators:g1
  gorking_generators:g2

I can then use them using:

rails g gorking_generators:g1
