wikipedia about "Obfuscate" - make ureadeable and decrease size!

but LuaObfuscator only increase file SIZE!!!

file with 1xx lines - size 4 KB

Hello, how can I desobfuscate a lua code please?

Hi so I've been experimenting with this and when I try to use it on files that have over 750+ lines it will cause an error and be unable to finish.

Error that I get when I try to do it to files with more than 750 lines:

Are you aware that this is an issue?

C:\Users\rober>C:\Python34\python.exe C:\Users\rober\Desktop\LuaObfuscator-master_main_.py [--input input.lua] [--output output.lua] [--level 1] [--dontcopy] [--debug]
Version: Beta 1.0.3 (Updated on Jun 09, 2016 @ 06:44 AM)

main.py: error: unrecognized arguments: [--input input.lua] [--output output.lua] [--level 1] [--dontcopy] [--debug]

So I am getting an error when trying to use this script on a linux(centos 7) system. It works perfectly fine on my windows pc, does this not work for linux systems because this is the error I get when I try to run it on linux:

Traceback (most recent call last): File "__main__.py", line 2, in <module> import obfuscator File "/home/obfuscator.py", line 3, in <module> import tokenizer File "/home/tokenizer.py", line 139 print("Fatal error occurred.", "Please check that your input is syntactically correct.", sep="\n") ^ SyntaxError: invalid syntax

lua.exe: D:/tools/AAA/LuaObfuscator/__decrypt_0.lua:1: '' expected near '�'

I run this decrypt file alft report a error,way?
Variable name illegal?

How can i do it

0 LoganDark ~/Desktop/ShEdit lua main.lua.obf
lua: main.lua.obf:1: <name> expected near char(226)

This happens whether I use level 1, 2, 3, or 4.

Here's the contents of the file I'm trying to obfuscate:

local lex = require('.lib.lexer')

local function getTokens(text)
  return ({lex(text)})[2].getTokenList()
end

local function flattenTokens(tokens)
  local flattened = {}

  local function append(type, data)
    local last = flattened[#flattened]

    if last ~= nil and last.type == type then
      last.data = last.data .. data
    else
      flattened[#flattened + 1] = {type = type, data = data}
    end
  end

  for t = 1, #tokens do
    local token = tokens[t]

    for w = #token.LeadingWhite, 1, -1 do
      local white = token.LeadingWhite[w]

      if white.Data ~= nil and white.Data:len() > 0 then
        append(white.Type, white.Data)
      end
    end

    if token.Data ~= nil and token.Data:len() > 0 then
      append(token.Type, token.Data)
    end
  end

  return flattened
end

local function flatToLines(flattened)
  local function splitTwoLines(tokens)
    local l1 = {}
    local l2 = {}

    for i = 1, #tokens do
      local token = tokens[i]
      local data = token.data
      local pos = data:find('\n')

      if pos then
        local before = data:sub(1, pos - 1)
        local after = data:sub(pos + 1)

        if before:len() > 0 then
          l1[#l1 + 1] = {type = token.type, data = before}
        end

        if after:len() > 0 then
          l2[#l2 + 1] = {type = token.type, data = after}
        end

        for x = i + 1, #tokens do
          l2[#l2 + 1] = {type = tokens[x].type, data = tokens[x].data}
        end

        return l1, l2
      else
        l1[#l1 + 1] = {type = token.type, data = data}
      end
    end

    return l1, nil
  end

  local lines = {}
  local current = flattened

  while current and #current > 0 do
    local l1, l2 = splitTwoLines(current)
    current = l2

    lines[#lines + 1] = l1
  end

  return lines
end

return {
  getTokens = getTokens,
  flattenTokens = flattenTokens,
  flatToLines = flatToLines
}

Here's the command I used to obfuscate it:

It says "Assuming "Data" is a global.", so I think it doesn't realize that tables can be accessed like table.key instead of just table['key'].

Example lua code

(Ignore the fact the code itself doesn't work in gmod, it's only about showing you an example)

python __main__.py --input .\sh_gmodstorehack.lua --output obf.lua

local html = vgui.Create("DHTML")
        html:SetPos(42, 42)
        html:SetWidth(280)
        html:SetHeight(120)
        html.button = vgui.Create("DButton")
        html.button:SetText("")
        html.button:SetPos(42, 42 + 120)
        html.button:SetSize(285, 30)

Also the code i showed is technically working even if there is no point of using it, and the obfuscated version doesn't compile in gmod
