Extended by:
T::Sig
Defined in:
lib/tapioca/dsl/compilers/rails_generators.rb

Overview

Tapioca::Dsl::Compilers::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 ~~~
