RuboCop Dry Import

A custom RuboCop extension that detects unused Import dependencies in classes using dry-rb’s dependency injection.

Add this line to your application's Gemfile:

gem 'rubocop-dry-import', require: false

Add the extension to your .rubocop.yml:

require:
  - rubocop_dry_import

Dry/UnusedImport:
  Enabled: true
  ImportName: 'Import' # Optional, defaults to "Import"

Run RuboCop as usual:

bundle exec rubocop

class FooService
  include Import['service_a', 'service_b']

  def call
    service_b.call
  end
end

Offense:

Include Import['service_a', 'service_b']
               ^^^^^^^^^^^ Imported dependency `service_a` is not used in the class.

Autocorrect: Not available (yet).
