luascope

Lua Scope is for looking into Lua chunk, or IOW, decode lua chunks. A Lua 5.1/5.2/5.3 binary chunk disassembler. LuaScope was inspired by Jein-Hong Man's ChunkSpy. LuaScope attempts to be lua version agnostic.

  • Based on ChunkSpy on Lua 5.1
  • Works as ChunkSpy on Lua 5.2
  • Works also as ChunkSpy on Lua 5.3

Dockerfile and shell scripts are provided for you to run 5.1/5.2/5.3 inside a container.

Compatibility

This was tested only on Ubuntu, but should work on any Unix-based system.

Steps to get started

  1. Make sure b2b directory has git submodule by running either git clone --recurse-submodules https://github.com/codervijo/luascope or git submodule update --init
  2. Make sure docker is installed
  3. Run ./lua53dock.sh to run luascope with Lua-5.3

If you do not have docker for any reason, do the following instead of 3 steps above: lua ./scope.lua
