Iteraptor

Handy enumerable operations:

• to_flatmap

Installation

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

```elixir
def deps do
  [{:iteraptor, "~> 0.3.0"}]
end
```

1. Ensure iteraptor is started before your application:

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

Usage

iex> %{a: %{b: %{c: 42, d: [nil, 42]}, e: [:f, 42]}} |> Iteraptor.to_flatmap
%{"a.b.c" => 42, "a.b.d.0" => nil, "a.b.d.1" => 42, "a.e.0" => :f, "a.e.1" => 42}

To be implicitly as explicit as possible, the current implementation creates string keys for those, containing joiner and atoms for those that haven’t.

That makes normal maps to be resistant to

iex> %{a: %{b: %{c: 42}}} |> Iteraptor.to_flatmap |> Iteraptor.from_flatmap
%{a: %{b: %{c: 42}}}

Changelog

As of version 0.3.0, the module supports Keyword on input, but it will be output as map for |> Iteraptor.to_flatmap |> Iteraptor.from_flatmap back and forth transformation.

As of version 0.4.0, the module supports structs on input. Structs will be automagically created on |> Iteraptor.from_flatmap from keys like StructName%field if a) this structure is known to the system and b) keys are consistent (e. g. there are no subsequent elements, belonging to different structs: ["S1%f" => 42, "S2%f" => 3.14].)
