Destructure

Adds Javascript-style destructuring to Elixir. Instead of:

def full_name(%{first_name: first_name, last_name: last_name}) do
  "#{first_name} #{last_name}"
end

You can write:

import Destructure

def full_name(d%{first_name, last_name}) do
  "#{first_name} #{last_name}"
end

It also works in case statements, like this:

case post(url, data) do
  {:ok, d%{body}} -> # instead of {:ok, %{body: body}}
    # use body variable
  _other ->
    # ...
end

Unlike Javascript, you can still bind custom variables:

d(%{first, last, email: mail}) = %{...}

See the Hex Documentation for more details.

Installation

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

```elixir
def deps do
  [{:destructure, "~> 0.1.1"}]
end
```

1. Ensure destructure is started before your application:

```elixir
def application do
  [applications: [:destructure]]
end
```
