Piparote

Another way to use Ruby object methods like pipes.

After reading an article about Elixir's pipe operator and some implementation people made on Ruby, I made this one as an exercise. Not sure if is good for production use.

Add this line to your application's Gemfile:

gem 'piparote'

And then execute:

$ bundle

Or install it yourself as:

$ gem install piparote

You can require the gem, include and use the Piparote module like this (here, using Nokogiri to parse my website):

require 'uri'
require 'open-uri'
require 'nokogiri'
require 'piparote'

include Piparote
include Nokogiri

puts 'http://eustaquiorangel.com'.
   URI.parse.
   open.read.
   HTML.parse.
   css('h2').
   map { |h2| h2.text }.
   join(' - ')

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
