Pipper

Pipper provides the <|> operator as a shorthand macro:

import Pipper

# This:
list = [1,2,3]
list <|> Enum.map(&(&1 * 2))
IO.inspect list # list == [2,4,6]

# Equivalent to:
list = [1,2,3]
list = list |> Enum.map(&(&1 * 2))
IO.inspect list

Wishes and Dreams

=|> would be a better operator, to make the assignment clearer. But it's not available.

Installation

If available in Hex, the package can be installed as:

1. Add pipper to your list of dependencies in mix.exs:

   def deps do [{:pipper, "~> 1.0.0"}] end

2. Ensure pipper is started before your application:

   def application do [applications: [:pipper]] end
