AtomicMap
A small utility to convert deep Elixir maps with mixed string/atom keys to atom-only keyed maps. Optionally with a safe option, to prevent atom space exhaustion of the Erlang VM.
Usage
iex> AtomicMap.convert(%{"a" => 2, "b" => %{"c" => 4}}, safe: true)
%{a: 2, b: %{c: 4}}
iex> AtomicMap.convert([ %{"c" => 1}, %{:c => 2}, %{"c" => %{:b => 4}}], safe: true]
[%{c: 1}, %{c: 2}, %{c: %{b: 4}}]
iex> AtomicMap.convert(%{ "a" => [ %{"c" => 1}, %{"c" => 2}] }, safe: true]
%{a: [%{c: 1}, %{c: 2}] }
Installation
If available in Hex, the package can be installed as:
Add atomic_map to your list of dependencies in
mix.exs
:def deps do [{:atomic_map, "~> 0.0.1"}] end
Ensure atomic_map is started before your application:
def application do [applications: [:atomic_map]] end
