Decompile BEAM files to Elixir source code

I have also done some experiments with the BEAM file. See the little beam_file project.

With BeamFile you can create byte, erl, and elixir-code (with the limitation discussed here) from the beam file.

Example:

defmodule Example.Math do
  @moduledoc "Math is Fun"

  def add(number_a, number_b), do: number_a + number_b

  def odd_or_even(a) do
    if rem(a, 2) == 0 do
      :even
    else
      :odd
    end
  end
end

iex> {:ok, code} = BeamFile.elixir_code(Example.Math)
iex> IO.puts(code)
defmodule Elixir.Example.Math do
  @moduledoc """
  Math is Fun
  """

  def add(number_a, number_b) do
    :erlang.+(number_a, number_b)
  end

  def odd_or_even(a) do
    case(:erlang.==(:erlang.rem(a, 2), 0)) do
      false ->
        :odd

      true ->
        :even
    end
  end
end
