Overview

‘Tapioca::Compilers::Dsl::ActiveSupportCurrentAttributes` decorates RBI files for all subclasses of [`ActiveSupport::CurrentAttributes`](api.rubyonrails.org/classes/ActiveSupport/CurrentAttributes.html).

For example, with the following singleton class

~~~rb class Current < ActiveSupport::CurrentAttributes

extend T::Sig

attribute :account

def helper
  # ...
end

sig { params(user_id: Integer).void }
def authenticate(user_id)
  # ...
end

end ~~~

this generator will produce an RBI file with the following content: ~~~rbi # typed: true

class Current

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

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

sig { params(account: T.untyped).returns(T.untyped) }
def self.account=(); end

sig { params(account: T.untyped).returns(T.untyped) }
def account=(); end

sig { params(user_id: Integer).void }
def self.authenticate(user_id); end

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

end ~~~
