transfigure

An experimental Ruby native extension that allows changing an object's class at runtime.

Installation

gem install transfigure

Usage

require 'transfigure'

The transfigure gem adds the transfigure_into! method onto Ruby's Object class. Pass it another class to switch out the object's current class to another one:

class Foo
end

class Bar
end

obj = Foo.new
obj.is_a?(Foo) # => true
obj.transfigure_into!(Bar)
obj.is_a?(Foo) # => false
obj.is_a?(Bar) # => true

Requirements

The code has only been tested on MRI (cruby) 3.1 and will definitely not work on other Ruby engines like JRuby or TruffleRuby.

Running Tests

bundle exec rspec
