Lua Decompiler ^new^

Lua, as a lightweight, high-level scripting language, is widely embedded in applications ranging from video games to network appliances. While the source code is often obfuscated or stripped in deployed applications, the underlying Lua Virtual Machine (LVM) executes a standardized bytecode. This paper explores the theoretical and practical challenges of Lua decompilation. We examine the architecture of the LVM, the structure of compiled chunks, the semantic gap between stack-based bytecode and register-based source code, and the modern arms race between decompilers and obfuscators.

The decompiler reads the binary structure of the luac file, including the header, functions, constants (strings, numbers), and instructions. It parses the bytecode format, which varies between Lua versions (e.g., Lua 5.1, 5.2, 5.3, 5.4, or LuaJIT). 2. Control Flow Reconstruction lua decompiler
