Research direction

Start by running the reproduction and tracing the CLI entry point for hanami g slice, especially how it discovers the Hanami app. Compare that behavior with the app defined in config/initializers/load_hanami.rb rather than config/app.rb; done means generating a slice works in this Rails setup without moving the app definition, with regression coverage for the scenario.

Description

bug help wanted

Describe the bug

We are working to incrementally migrate a Rails application to Hanami, gradually replacing an area of the Rails code with its own dedicated slice as we go (taking this post as inspiration and a template). As such, we have Hanami stuff in slices/**/* and config/initializers/load_hanami.rb, but nothing in config/app.rb.

To Reproduce

rails new ibis
cd ibis
bundle add hanami
cat << END_INITIALIZER > config/initializers/load_hanami.rb
require 'hanami'
module IbisHanami
  class App < Hanami::App
    prepare_container { |container| container.autoloader.ignore('app') }
  end
end
Hanami.boot
END_INITIALIZER
mkdir -p slices/osprey
cat << END_SLICE > slices/osprey/my_class.rb
module Osprey
  class MyClass
    def call = 'Hello from slice!'
  end
end
END_SLICE
hanami g slice pigeon # does not generate a new slice, instead gives the usage docs for creating a new Hanami app

Expected behavior

It would be nice if there were a way to use the convenient CLI commands in applications that use hanami, but define their Hanami::App somewhere other than config/app.rb
