Is it possible to decompile BEAM files with :debug_info chunk to actual Elixir source code? This data is from :debug_info iex(2)> Secret |> :code.which |> :beam_lib.chunks([:debug_info]) |> elem(1) |> elem(1) |> Keyword.get(:debug_info) |> elem(2) |> elem(1) |> Map.get(:definitions) [{{:hello, 0}, …

[image] tim2CF: If it’s possible to transform :debug_info to AST - please write how, thanks! What would the use case for this? Maybe there is a simpler way to achieve what you want?

The idea is to create a analysis tool that will work with AST of Elixir program

The problem is that the transformation from Elixir to BEAM bytecode loses information. A simple example: a = 1 a = 2 will result in bytecode somewhat like a = 1 a1= 2 Because rebinding variables isn’t possible in bytecode, so Elixir fakes it. There are plenty of such examples. Decompiling BEAM b…

[image] cdegroot: but getting back to the original Elixir AST is, I think, almost impossible. At the time you wrote this it seems that was already possible with Dbgi chunk, that you can see the pull request for it here , and get some more background from this 2017 Jose video: [The Fe…

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…

Hello dear friends. hope you can help me. I have some .beam files I want to decompile into .erl files (source code) How can I do this. Please help me, I will thank you.

It depends on if the beam file includes the AST or not. Try this: https://gist.github.com/shino/e5d76ced2e44cc6a21d0 I believe there are some mechanisms in the compiler to turn the beam bytecode into Core Erlang if you just want to deduce the logic similar to an …
