This adds the method to Ruby. It pipes in the returned value of the left as the first parameter of the Proc (or anything with :call defined) on the right.

Unicode ᐅ

To enter ᐅ you need to:

  • Linux: type CTRl-SHIFT-U and then 1405 followed by the Space or Enter key.
  • Mac: hold the Option key while you type 1405 and then release the Option key.
  • VIM: press CTRL-v then SHIFT-U then 1405 and hit Enter.
  • Emacs: press CTRL-x then 8 then Enter and type 1405 and hit Enter.


Add this line to your application's Gemfile:

gem 'elixirize'

And then execute:

$ bundle

Or install it yourself as:

$ gem install elixirize


def add a, b
  a + b

subtract = ->a, b{ a - b }

add(4, 5). subtract, 15
# => -6

def divide a, b
  a / b

add(40, 60). method(:divide), 20
# => 5


Since Ruby is designed largely to call methods on the object that was returned I've written the ~ method on Symbol to allow method calls on the returned object rather than only being the first parameter passed in.


s = "a b c d"
val = s.
  (~:split, " ").
  (~:join, "-").

# => "A-b-c-d"

You can mix both behaviors without any issue.

This may seem counter intuitive as it's the same thing as just calling the method on the object, but consider this a noticeable refactoring step. If you're designing a project in a manner where you want results piped in as the first parameter then the tilde-symbol will be your TODO reminder to convert/refactor how your code base is implemented.


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

Add ᐅ piping method to Ruby for an Elixir feel. First parameter must be an object that responds to :call.
