Tooling to make it possible to run "new" code in old Elixir versions.

Currently the following functions not available before 1.3 can be backported:

• String.trim
• String.to_charlist
• String.pad_leading
• String.pad_trailing can replace trim and to_charlist functions which were not available prior to Elixir 1.3.

If available in Hex, the package can be installed by adding backports to your list of dependencies in mix.exs:

def deps do
  [{:backports, "~> 0.2.0"}]
end

Whatever module uses a function that is not available, just include Backports

This code will work in Elixir 1.1 and 1.2

defmodule Foo do
  use Backports

  def bar do
    String.trim("  amazing   ")
  end
end
