# Maybe

[![Hex.pm](https://img.shields.io/hexpm/v/maybe.svg)](https://hex.pm/packages/maybe)

[![Build Status](https://travis-ci.org/infinitered/maybe.svg?branch=master)](https://travis-ci.org/infinitered/maybe)

Access nested Elixir maps and structs, protected from `nil`. Somewhat similar to "Optionals" in Apple Swift.

```elixir

import Maybe

info = %{city: %{name: "Portland"}}

maybe(info.city.name)

# => "Portland"

map = %{}

maybe(map.city.name)

# => nil

```

See the original [forum post](https://elixirforum.com/t/maybe-nil-protection-for-nested-structs/468) for

more an explanation of the problem this package solves.

## Installation

Add `maybe` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:maybe, "~> 1.0.0"}

  ]

end

```

See [the documentation](https://hexdocs.pm/maybe) for more details.
