Overview

‘Tapioca::Dsl::Compilers::ActiveRecordScope` decorates RBI files for subclasses of `ActiveRecord::Base` which declare [`scope` fields](api.rubyonrails.org/classes/ActiveRecord/Scoping/Named/ClassMethods.html#method-i-scope).

For example, with the following ‘ActiveRecord::Base` subclass:

~~~rb class Post < ApplicationRecord

scope :public_kind, -> { where.not(kind: 'private') }
scope :private_kind, -> { where(kind: 'private') }

end ~~~

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

~~~rbi # post.rbi # typed: true class Post

extend GeneratedRelationMethods

module GeneratedRelationMethods
  sig { params(args: T.untyped, blk: T.untyped).returns(T.untyped) }
  def private_kind(*args, &blk); end

  sig { params(args: T.untyped, blk: T.untyped).returns(T.untyped) }
  def public_kind(*args, &blk); end
end

end ~~~
