ObjectAs

A simple refinement to get Object#as

Installation

Add this line to your application's Gemfile:

gem 'object_as'

And then execute:

$ bundle

Or install it yourself as:

$ gem install object_as

Object#as it much like Object#tap except that it returns the value of the block instead of the value being tapped.

> "Ruby".as {|n| n.reverse }
=> "ybuR"

Object#as is useful when chaining methods. This is a complete Ruby source file:

require 'object_as'
using ObjectAs
[1, 2, 3].map {|x| x * x }.as {|array| array.reverse }.each {|x| puts x }
# prints 9, 4 and 1

For Ruby versions older than 2.1, there is a way to use Object#as without refinements. This method uses monkeypatching.

require 'object_as_no_refinements'
[1, 2, 3].map {|x| x * x }.as {|array| array.reverse }.each {|x| puts x }
# prints 9, 4 and 1
