# Backports

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.

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed

by adding `backports` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [{:backports, "~> 0.2.0"}]

end

```

## Usage

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

This code will work in Elixir 1.1 and 1.2

```elixir

defmodule Foo do

  use Backports

  def bar do

    String.trim("  amazing   ")

  end

end

```
