Which lines are whose

Select nodes and press P to see the lines they wrote, picked out of the real generated file. A pure node has no line of its own, so the preview lights the line its value ends up in.

Then 0.33.0 the whole script with nothing selected.

P, with or without a selection

Try it: Click a node in the graph. Shift-click to add another, or click the canvas to preview the whole script.

2 / 110.1.0

Find a node by name

Right-click the canvas and type. Nodes are found by their names, by what other tools call them (sleep finds Wait), and by the Luau they write (if finds Branch).

Then 0.45.0 the Luau it writes, 0.74.0 other names.

Right-click the canvas

Try it: Type sleep into the search, then walk the list with ↑ ↓.

3 / 110.50.0

Or by how it looks

The node picker lists the same nodes and draws each one as you reach it, in your wire style, for when you remember a node's shape better than its name. Press and hold with two fingers to open it on a tablet.

Then 0.74.0 two fingers on a touch screen.

Ctrl + Right-click

Try it: Point at a node in the list, or walk it with the arrow keys.

4 / 110.90.0

Code that knows its names

Rest on a name in Code Block or a Luau file and the editor says what it is: a local and its type, a parameter, a method with its signature and a link to where Roblox documents it.

Then 0.93.0 in .luau files, 0.94.0 types and methods.

Hover, or move the caret onto a name

Try it: Hover stats, IsA or award. Tab steps through the names.

local Players = game:GetService("Players")
local coins = 0

local function award(player: Player, amount: number)
	coins += amount
	local stats = player:FindFirstChild("leaderstats")
	if stats and stats:IsA("Folder") then
		print(player.Name, coins)
	end
end

Players.PlayerAdded:Connect(function(player)
	award(player, 10)
end)

5 / 110.89.0

Completion that knows Roblox

As you type Luau, the editor offers what fits where the cursor is: Roblox's classes in Instance.new and :IsA, its services in :GetService, and a datatype's constructors and constants after its dot.

Type, then ↑ ↓ and Enter or Tab

Try it: Pick where to ask, then keep typing in the box. Enter takes the option that is lit.

local part = Instance.new("")

local storage = game:GetService("")

if hit:IsA("") then

local up = Vector3.

6 / 110.104.0

Your own docs, as you write them

Doc comments above a function show in its hover: prose, examples, parameters and returns. Moonwave's @class, @prop and @interface are read too, and the tags are coloured where you write them.

Then 0.110.0 @class, @prop and @interface.

--[=[ ]=] or --- above a declaration

Try it: Hover Inventory, capacity and add.

--[=[
	@class Inventory
	What a player is carrying, by item name.
]=]
local Inventory = {}

--[=[
	@prop capacity number
	@within Inventory
	How many items fit.
]=]
Inventory.capacity = 20

--[=[
	Adds an item, unless the inventory is full.

	```lua
	Inventory.add(bag, "Sword")
	```

	@param bag { string } -- the items held now
	@param item string -- what to add
	@return boolean -- whether it fitted
]=]
function Inventory.add(bag: { string }, item: string): boolean
	if #bag >= Inventory.capacity then
		return false
	end
	table.insert(bag, item)
	return true
end

return Inventory

Inventory.add(bag, "Sword")

From the DataModel into your code

The Project panel's DataModel tab lists your place as Studio's Explorer does. Drag an instance into Code Block: on a blank line it becomes a whole local, anywhere else the path alone, starting from a local that already holds part of the way.

Then 0.128.0 dragged into Code Block, 0.151.0 from the locals in scope.

Drag a row, or Enter on it and then on where it goes

Try it: Drag Config onto the blank line: it starts from Shared. Then try Shared itself, or Door into print().

local Shared = game:GetService("ReplicatedStorage").Shared

local function openDoor()
	local Config = Shared.Config
	print(workspace.House.Door)
end

8 / 110.107.0

Wally packages, in the tree

wally.toml sits in Graph content with each package it lists and the version installed, and Packages shows under Compile content. Add from Wally… on its menu installs a package with what it depends on.

Then 0.112.0 Add from Wally, 0.113.0 Remove a package.

Right-click wally.toml

Try it: Switch to after Add from Wally… and Flux arrives with its version.

9 / 110.140.0In progress

Luau in, graph out

Import as graph turns a .luau file's statements into nodes; what has no node yet stays as Luau text, and comments become comment boxes. Still in progress, so test what you import.

Then 0.143.0 Verbatim, Tidy and Modern, 0.166.0 names and types as written, 0.167.0 laid out in rows, 0.169.0 the library's own nodes, 0.171.0 event handlers and threads.

Right-click a .luau file

Try it: Tap a line of either file, or a node, to see what it became. Verbatim keeps one chain, Tidy cuts it into rows, and Modern writes the and … or line as an if-expression.

The work fills the window

Controls float over the graph in groups. On a computer the panels are cards that dock, fold and take tabs; on a tablet they open from the groups along the top; on a phone they are sheets from a bar along the bottom.

Then 0.122.0 tabs and folding, 0.130.0 the panels redrawn.

The same editor on any screen

Try it: Switch between Computer, Tablet and Phone. Each is the editor itself, on that screen, with the same graph open.

11 / 110.144.0

A menu for each kind of row

Every context menu is the same menu: it opens over everything, stays on screen, and is divided where its entries are different kinds of thing. What it offers depends on what you opened it on: a folder, a graph, Wally's file, Luau you wrote, or Luau Roswaal writes.

Right-click, then ↑ ↓ Enter Esc

Try it: Right-click each row in the tree. Only Luau you wrote, and a folder holding some, offer to import it as graphs, and only wally.toml offers packages.
