A blazingly fast Lua(u) decompiler, forked from medal.

Usage

Usage: medal.exe <COMMAND>

Commands:
  decompile  Decompile a single bytecode file, either raw or base64 encoded
  serve      Start a simple web server to handle decompiling
  help       Print this message or the help of the given subcommand(s)

Options:
  -h, --help     Print help
  -V, --version  Print version

Script

When using medal serve, you can use the decompiler directly inside of your executor. These scripts assume you are self-hosting the decompiler. If you are using some sort of API, make sure to replace http://localhost:3000 or http://10.0.2.2:3000 with the correct API base.

Windows

getgenv().decompile = function(script_instance)
  local bytecode = getscriptbytecode(script_instance)
  local encoded = crypt.base64encode(bytecode)
  return request(
    {
      Url = "http://localhost:3000/luau/decompile",
      Method = "POST",
      Body = encoded
    }
  ).Body
end

loadstring(game:HttpGet("https://raw.githubusercontent.com/luau/SynSaveInstance/main/saveinstance.luau"))()({
  mode = "scripts",
  NilInstances = true,
})

Android Emulator

Note

• If you have a proxy enabled in WiFi settings, add 10.0.2.2 to the exceptions or disable the proxy
• If you are using a VPN, allow LAN connections

Run the web-server on your actual machine.

If you are using an emulator, localhost will not work since that will refer to the emulator's device. Instead, we must use 10.0.2.2 instead. To test if everything is working, on your actual machine [http://localhost:3000/] should load fine, and on the emulator's browser, [http://10.0.2.2:3000/] should load. If your emulator is giving you HTTP connection fail errors, then you can try ngrok instead.

getgenv().decompile = function(script_instance)
  local bytecode = getscriptbytecode(script_instance)
  local encoded = crypt.base64encode(bytecode)
  return request(
    {
      Url = "http://10.0.2.2:3000/luau/decompile",
      Method = "POST",
      Body = encoded
    }
  ).Body
end

loadstring(game:HttpGet("https://raw.githubusercontent.com/luau/SynSaveInstance/main/saveinstance.luau"))()({
  mode = "scripts",
  NilInstances = true,
})
