Luau Dissasembler

This is an effient luau dissasembler made in Lua 5.1. (THIS IS NOT FINISHED)

Usage

lua main.lua [luauc file]

Roblox Bytecode

Due to obvious reasons disassembling Roblox bytecode will not have opcode information or register deduction, however this can be easily fixed by remapping the opcodes in op.lua, but this is not needed to disassemble Roblox bytecode.

An example of this is:

Proto[0]
> #Stack: 2
> #Params: 0
> #Name: "undefined"

Constants[2]
> [0] (string) "print"
> [1] (function) "function: 00966F60"
> [2] (string) "Hello World!"

Instructions[5]
> [0->163] 163 { 0, 0, 0 }
> [1->65700] 164 { 0, 1, 0 }
> [2->1073741824] LOP_NOP { 0, 0, 64 }
> [3->131439] 111 { 1, 2, 0 }
> [4->16908447] 159 { 0, 2, 1 }
> [5->65666] 130 { 0, 1, 0 }

as you can see, all opcode names are missing except NOP.
