LuaJIT Raw-Bytecode Decompiler (LJD)

Based on Dr-MTN/luajit-decompiler

WARNING! This code is not finished or tested! There is not even the slightest warranty that the resulting code is even close to the original. Use the decompiled code at your own risk.

SECOND WARNING! This is all a huge prototype. The "release" version should be written in Lua itself, because it's cool to decompile the decompiler — a great test too!

Requirements:

Python 3.7+ from Python.org

How To Use:

Use helper functions in tools.py, e.g. set_luajit_version, process_bytes, process_file, process_folder.

Typical usage:

from ljd.tools import set_luajit_version, process_file

# default version is 21, for LuaJIT-2.0.1
# set version to 20 for LuaJIT-2.0.0
set_luajit_version(20)

process_file('byte-code-path.lj', 'output-path.lua')

Licence:

Use GPL licence.

Notification from Dr-MTN/luajit-decompiler:

The original LJD (and Aussiemon's modifications) are distributed under the MIT licence, and a copy of this is included as LICENSE-upstream. However, all changes made by myself (Campbell "ZNixian" Suter) are licenced under the GNU General Public Licence, version 3 or any later version of your choice (a copy of which is available in the LICENSE file supplied with the source code).

I've chosen this license due to certain dynamics of the videogame modding scene for which these changes were made. If you have a use for this outside of games, and need a less restrictive licence, please let me know and I'll most likely be fine to relicence the project either to MIT or (preferrably) LGPL.

Also note that while this licence did not appear as my first modification to this project, I did not distribute the source before making this change, and never offered those changes under the original licence (even if the licence file supplied in those revisions was the original one).
