# 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:
```ruby
gem 'ruby2_keywords'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby2_keywords
## Usage
For class/module instance methods:
```ruby
require 'ruby2_keywords'
module YourModule
ruby2_keywords def delegating_method(*args)
other_method(*args)
end
end
```
For global methods:
```ruby
require 'ruby2_keywords'
ruby2_keywords def oldstyle_keywords(options = {})
end
```
You can do the same for a method defined by `Module#define_method`:
```ruby
define_method :delegating_method do |*args, &block|
other_method(*args, &block)
end
ruby2_keywords :delegating_method
```
