jazz - JSON handling library for Elixir

=======================================

Jazz is a JSON handling library written in Elixir, for Elixir.

Examples

--------

```elixir

use Jazz

JSON.encode!(%{name: "David", surname: "Davidson"})

  |> IO.puts # => {"name":"David","surname":"Davidson"}

JSON.decode!(~S/{"name":"David","surname":"Davidson"}/)

  |> IO.inspect # => %{"name" => "David", "surname" => "Davidson"}

JSON.decode!(~S/{"name":"David","surname":"Davidson"}/, keys: :atoms)

  |> IO.inspect # => %{name: "David", surname: "Davidson"}

# would raise if the keys weren't already existing atoms

JSON.decode!(~S/{"name":"David","surname":"Davidson"}/, keys: :atoms!)

  |> IO.inspect # => %{name: "David", surname: "Davidson"}

defmodule Person do

  defstruct name: nil, surname: nil

end

JSON.encode!(%Person{name: "David", surname: "Davidson"})

  |> IO.puts # => {"name":"David","surname":"Davidson"}

JSON.decode!(~S/{"name":"David","surname":"Davidson"}/, as: Person)

  |> IO.inspect # => %Person{name: "David", surname: "Davidson"}

defimpl JSON.Encoder, for: HashDict do

  def encode(self, options) do

    HashDict.to_list(self) |> Enum.into(%{})

  end

end

defimpl JSON.Decoder, for: HashDict do

  def decode(_new, parsed, _options) do

    parsed |> Enum.into(HashDict.new)

  end

end

JSON.encode!(HashDict.new([name: "David", surname: "Davidson"]))

  |> IO.puts # => {"name":"David","surname":"Davidson"}

JSON.decode!(~S/{"name":"David","surname":"Davidson"}/, as: HashDict)

  |> IO.inspect # => #HashDict<[{"name", "David" }, { "surname", "Davidson" }]>
