Defined in:
lib/tapioca/compilers/dsl/frozen_record.rb

Overview

Tapioca::Compilers::Dsl::FrozenRecord generates RBI files for subclasses of FrozenRecord::Base.

For example, with the following FrozenRecord class:

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

and the following YAML file:

# 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:

# 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
