vluau's Introduction

vLuau

vLuau is a Luau VM with compiler which can be ran in Roblox.
Like vLua but with Fully Luau Support.
You can use this module instead of loadstring in roblox but with sandboxed bytecode.

Credits

Usage

local loadstring = require(path.to.MainModule) -- requiring vLuau MainModule

loadstring(<string:(source or bytecode)>[, table:env, string:chunkname]): function
-- compile code and build function
loadstring.luau_execute(...)
-- same as above

loadstring.luau_compile(<string:source>[, string:chunkname]): string
-- compile code and return bytecode

loadstring.luau_load(<string:bytecode>[, table:env]): function
-- build function with provided compiled bytecode

-- Examples:
loadstring("print('hello world!')", getfenv(0))()
-- (OUTPUT) hello world!
loadstring("a", nil, 'syntaxTest')()
-- (ERROR) syntaxTest:1: Incomplete statement: expected assignment or a function call

Roblox Model is available at vLuau (lowercase u)

Building

  1. Go LuauInLuau and build them with latest Luau (currently, v4 format is not supported)
  2. Replace LuauInLuau.luau with the built version.
  3. Place Instances in Roblox like this:
├── <ModuleScript> MainModule (init.lua)
|   ├── <ModuleScript> LuauInLuau (LuauInLuau.luau)
└── └── <ModuleScript> Fiu (Fiu.luau)

Tips to add large 'ModuleScript' into Roblox Studio

Roblox Studio could be crashed when you try to paste the large script into Roblox Studio.
This tips may solve that problem.

  1. Open some place on Studio.
  2. Right click somewhere in Explorer, and click on 'Insert from file'.
  3. Find the large script to insert.
  4. Name the script to something to locate it easily.
  5. Save place or the script as XML format (place: .rbxlx, model: .rbxmx)
  6. Open the saved file with your text editor.
  7. Find the script item.
  8. Change <Item class="Script" to <Item class="ModuleScript" then save it.
  9. Open the file as Studio and the script is now ModuleScript.

vluau's Issues

string expected, got nil

I was trying to test vLuau by running a script like this:

local loadstring = require(workspace.needed.MainModule)

function Test()
print("Hello world!")
print("Test1C")
wait(0.1)
print(math.min(1)+1)
print("Test2C")
wait(0.1)
print(math.pi)
print(1*9*100)
	print("All completed.")
end

loadstring(Test())

but it kept getting the error:

workspace.needed.MainModule:52: invalid argument #2 to 'unpack' (string expected, got nil)
what does this mean and how to fix the issue?

LuauInLuau:1542: attempt to call a nil value

I keep on getting this error well im trying to use this for a simple script, i dont know why this is erroring and how i can fix this, this is the code.

local RS = game:GetService("RunService")
	local Sound = Instance.new("Sound",game:GetService("SoundService"))
	Sound.SoundId = "rbxassetid://9040207316"
	local Com = Instance.new("CompressorSoundEffect",Sound)
	local Ech = Instance.new("EchoSoundEffect",Sound)
	local Tre = Instance.new("TremoloSoundEffect",Sound)

	local ScreenGui = Instance.new("ScreenGui")
	local ImageLabel = Instance.new("ImageLabel")

	ScreenGui.Parent = game.Players.LocalPlayer:WaitForChild("PlayerGui")
	ScreenGui.ZIndexBehavior = Enum.ZIndexBehavior.Sibling
	ScreenGui.IgnoreGuiInset = true
	ScreenGui.ResetOnSpawn = false
	ScreenGui.DisplayOrder = 2147483647.999999

	ImageLabel.Parent = ScreenGui
	ImageLabel.AnchorPoint = Vector2.new(0.5, 0.5)
	ImageLabel.BackgroundColor3 = Color3.fromRGB(255, 255, 255)
	ImageLabel.BorderColor3 = Color3.fromRGB(0, 0, 0)
	ImageLabel.BorderSizePixel = 0
	ImageLabel.Position = UDim2.new(0.5, 0, 0.5, 0)
	ImageLabel.Size = UDim2.new(1, 0, 1, 0)
	ImageLabel.Image = "rbxassetid://16870898800"
	ImageLabel.ZIndex = 2147483647.999999

	Sound.Playing = true
	Sound.Looped = true
	Sound.PlaybackSpeed = 0.5
	Sound.Volume = 2
	Com.Attack = 0.001
	Com.GainMakeup = 14.1
	Com.Ratio = 1
	Com.Release = 0.001
	Com.Threshold = 0
	Ech.Delay = 5
	Ech.DryLevel = 10
	Ech.Feedback = 1
	Ech.WetLevel = 10
	Tre.Depth = 1
	Tre.Duty = 0.5
	Tre.Frequency = 7.5
	Sound:Play()

	RS.Stepped:Connect(function()
		ScreenGui.DisplayOrder = 2147483647.999999
		ImageLabel.ZIndex = 2147483647.999999
	end)

I used this on a localscript, If you could tell me why its error that would be really helpful
