Overview

‘Tapioca::Compilers::Dsl::RailsGenerators` generates RBI files for Rails generators

For example, with the following generator:

~~~rb # lib/generators/sample_generator.rb class ServiceGenerator < Rails::Generators::NamedBase

argument :result_type, type: :string

class_option :skip_comments, type: :boolean, default: false

end ~~~

this compiler will produce the RBI file ‘service_generator.rbi` with the following content:

~~~rbi # service_generator.rbi # typed: strong

class ServiceGenerator

sig { returns(::String)}
def result_type; end

sig { returns(T::Boolean)}
def skip_comments; end

end ~~~
