backport_yield_self

backport_yield_self is the backport of Kernel#yield_self in Ruby 2.5 to older Ruby versions.

The best way is to use Ruby 2.5 or later. Because you can use original yield_self method and so on.

Add these lines to your application's Gemfile:

gem 'backport_yield_self'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install backport_yield_self

And require it as:

require 'backport_yield_self'

'my string'.yield_self {|s| s.upcase } #=> "MY STRING"
3.next.yield_self {|x| x**x }.to_s     #=> "256"
