Defined in:

Overview

`Tapioca::Compilers::Dsl::FrozenRecord` generates RBI files for subclasses of [`FrozenRecord::Base`](github.com/byroot/frozen_record).

For example, with the following FrozenRecord class:

~~~rb # student.rb class Student < FrozenRecord::Base end ~~~

and the following YAML file:

~~~ yaml # students.yml

  • id: 1 first_name: John last_name: Smith

  • id: 2 first_name: Dan last_name: Lord

~~~

this generator will produce the RBI file `student.rbi` with the following content:

~~~rbi # Student.rbi # typed: strong class Student

include FrozenRecordAttributeMethods

module FrozenRecordAttributeMethods
  sig { returns(T.untyped) }
  def first_name; end

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

  sig { returns(T.untyped) }
  def id; end

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

  sig { returns(T.untyped) }
  def last_name; end

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

end ~~~
