Crutches Build Status Docs Status Hex Version License

Utility library for Elixir, designed to complement the standard library bundled with the language. This project aims to provide extra functions that can be useful in most projects, but haven't made it into the standard library yet. Similar to and inspired by ActiveSupport.


You can get Crutches from Hex. Add the following to your

file and run
mix deps.get
defp deps do
  [{:crutches, "~> 1.0.0"}]


If you want to import all functions provided by Crutches,

it in your module:
defmodule Foo do
  use Crutches

The above aliases

. All modules and functions in the library will be available to you. Take a look at the API reference for a list of modules.

If you only need a specific part of the library, you can

defmodule Bar do
  import Crutches.Option
  # Or:
  alias Crutches.Option

Again, refer to the API reference for a list of modules and functions that you can find in Crutches.

Project status, compatibility and versioning


all APIs are stable and subject to semantic versioning.

We specifically test our code against the following versions of Erlang/OTP and Elixir:

Erlang: 18.0, 19.0, 20.0 Elixir: 1.1.1, 1.2.6, 1.3.4, 1.4.0, 1.5.1

Learn Elixir with us!

Crutches is a great for Elixir beginners to contribute to. We are writing convenience functions as an addition to the Elixir standard library, a lot of which are inspired by ActiveSupport (a similar project from the Ruby world).

The great thing about a utility library is that it is easy to contribute without having to know a lot about the entire codebase. You can easily add a new function in a vacuum, without having to know about the rest of the codebase. Furthermore, we provide a list of features to be implemented, complete with tests, so you can get started right away, even if you don't have any ideas.

We want to be a safe place for anyone to get started with Elixir or with contributing to an open source project. If you see anything that isn't proper in your eyes, then be sure to let one of the collaborators know!

Sounds good? Take a look at the contributing information to get started. If anything is unclear, or if you are unsure about something, feel free to contact one of the collaborators.
