Hanami Ruby 3.0

Monkey patches Hanami components to support Ruby 3.0. This includes

1. Copying Hanami 1.3.X files to support Ruby 3 syntax.
2. Copying Hanami 1.3.X files and getting rid of deprecated DRY libraries to allow upgrade of those gems.

Overview

To use this gem, make sure your app works with Ruby 2.7.6.

This should only be installed for a short time, during the Hanami Upgrade process. It just overrides a few of the Hanami classes, replacing code raising deprecation warnings with updated code supported Ruby 3.0 syntax.

Warning!!!

This code just overrides the Hanami components, does not introduce tests of any sort. Before you upgrade your Ruby version, make sure, that your code is covered with tests, and your deprecations tracked.

Usage

In your project, install overrides for the given classes

# custom-hanami-utils is required to allow installing Hanami 1.3.5 with ruby 3
gem 'hanami-utils', github: 'swilgosz/hanami-utils', branch: '1.3.x-support-ruby-3.0'

# Deprecated DRY libraries are renamed to RDY - we install those so we can update our DRY libraries freely.
%w[core container configurable equalizer monads logic types struct validation].each do |name|
  gem "rdy-#{name}", ascenda_private: "Kaligo/rdy", glob: "lib/rdy/#{name}/rdy-#{name}.gemspec"
end

gem 'hanami-ruby3'

Then load overrides in the environment.rb, after loading Hanami files.

require 'hanami/setup'
require 'hanami/ruby3'

With this, you should not have any Ruby Deprecation warnings and you should be fine do update to Ruby 3.0
