/app/vendor/bundle/ruby/3.3.0/gems/r18n-core-5.0.1/lib/r18n-core/locale.rb:21: warning: bigdecimal was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add bigdecimal to your Gemfile or gemspec. Also contact author of r18n-core-5.0.1 to add bigdecimal into its gemspec.

I would volunteer if needed, just let me know 🙋‍♂️

How can I reproduce it? With bundle exec rspec and Ruby 3.3.5 I see no warnings about bigdecimal.

Provoke the warning in a mini example

Hope this helps 🤞

You need rackup to run the tiny roda based example.

gem install rackup

Then create a new directory and put the following file named config.ru in it. It is the example from roda's landing page, with the bundler bits you need to actually run.

# content of config.ru
require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem "roda-i18n", "~> 0.6.0"
  gem "roda", "~> 3.84"
end

# cat config.ru
require "roda"

class App < Roda
  plugin :i18n

  route do |r|
    # GET / request
    r.root do
      r.redirect "/hello"
    end

    # /hello branch
    r.on "hello" do
      # Set variable for all routes in /hello branch
      @greeting = 'Hello'

      # GET /hello/world request
      r.get "world" do
        "#{@greeting} world!"
      end

      # /hello request
      r.is do
        # GET /hello request
        r.get do
          "#{@greeting}!"
        end

        # POST /hello request
        r.post do
          puts "Someone said #{@greeting}!"
          r.redirect
        end
      end
    end
  end
end

run App.freeze.app

run this app / config.ru file:

$ rackup
