ruby2_keywords

Provides empty Module#ruby2_keywords method, for the forward source-level compatibility against ruby2.7 and ruby3.

Installation

Add this line to your application's Gemfile:

gem 'ruby2_keywords'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby2_keywords

Usage

For class/module instance methods:

require 'ruby2_keywords'

module YourModule
  ruby2_keywords def delegating_method(*args)
    other_method(*args)
  end
end

For global methods:

require 'ruby2_keywords'

ruby2_keywords def oldstyle_keywords(options = {})
end

You can do the same for a method defined by Module#define_method:

define_method :delegating_method do |*args, &block|
  other_method(*args, &block)
end
ruby2_keywords :delegating_method
