ObjectThru

This is a ruby gem which provides Object#thru as a complement to Ruby's Object#tap. Object#thru comes handy if you are doing lots of chained/functional style programming and you want to return the result of a chained call without the need for temp variables.

Add this line to your application's Gemfile:

gem 'object_thru'

And then execute:

$ bundle

Or install it yourself as:

$ gem install object_thru

Object#thru accepts either a block or a callable. If a block is given, the block is called with the object, Object#thru was called on. If called with a callable, the callable is called with the object, Object#thru was called on.

require "object_thru"

[1,2,3]
.map { |integer| integer * 3 }
.reject { |integer| integer <= 9 }
.thru do |array|
  array.length <= 1 ? array.first : array
end
# => 9

require "object_thru"

ensure_integer = -> (object) { object.respond_to?(:to_i) ? object.to_i : 0 }
"123".thru(ensure_integer)
# => 123
