Lua 5.3 fork with added functionality to support other environments
This was created for one of my old obfuscation projects, but since I have moved on from writing Lua obfuscators, I have decided to make this project public. It is mostly comprised of patches from the lua-users wiki and some that I found on Google.
It adds features that aim to be compatible with scripts written for the following platforms
- Luau (no typechecking or underscore number separators)
- FiveM
- Garry's Mod (no C style comments)
This project was created so the resulting bytecode could be embedded in a custom virtual machine written in Lua for the purpose of obfuscating scripts for multiple platforms with a single version of Lua.
This code has not been tested in production, and although the test suite passes, here (most likely) be dragons. This project will not be updated, and support will not be provided if you run into problems. Use at your own risk. The code is likely very messy and has a lot of room for optimizations, as this is my first C project (although I wouldn't call it that, as most of the work done here was applying patches written by others).
The build system has been modified to use CMake, based on this project. You can view the .github/workflows directory to see how to build and test on your platform.
For support with scripts written for Roblox, a continue keyword was added and both it and the goto keyword have been modified to be contextual. This means you can use them as variable names without any syntax errors.
Apollo contains support for FiveM's backtick string literal for calculating Jenkins one-at-a-time hashes.
Apollo allows the more traditional style comparison operators, || (or), && (and), ! (unary not), and != (inequality)
Relevant file: comparison test
Compound assignment operators have been added for addition, subtraction, multiplication, division, modulus, exponentiation, and concatenation. An increment operator (++) is also included.
Relevant file: compound assignment test
Apollo allows for iteration of a table without calling a function (defaults to next). The __iter metamethod can be set to control which function is used.
Relevant file: generalized iteration test
Support for binary literals has been added, following the 0b syntax. (example: 0b11001 == 25)
