Syntax

Cluaupp does not define the language. Write CL++ 0.3.2 (.clpp / .clp / .clh); clpp emits Luau. Course and reference: kartzrbx.github.io/CLPP. Fences use language id clpp.

void init() is the script entry. There is no int main().

Accessors

This table is law. CL++ does not use ->. There is no : for tables or properties. Instances are class names: Player player, never Player*.

Write	Meaning	Luau
player.Name / player.Kick() / workspace.FindFirstChild("x")	property and instance method	. / :
age: int / player:Kick()	type or protected pcall	: / pcall
task::wait / Vector3::new / Class::Method / signal::Connect	static, method definition, manual Connect	. / :
"hi " .: name	concat	..
signal~>Connect(fn) / ~>Once	Sweep Connect / Once (default)	sweep:Add(..., "Disconnect")
name.Fire(...)	fire a signal	:Fire
items[0] / data["Coins"]	index only	[key]
Enum.Material.Plastic	enum	same

. on an instance method still passes self (player.Kick() → player:Kick()). player:Kick() in CL++ is the pcall form.

post / warn / report → print / warn / error. to_string / to_number / to_bool. null is nil. Range-for is for (T x in list).

Anonymous callbacks are func (params) { } / func () { }. [] is indexing only.

Exclusive CL++ (compiled by clpp)

guard (player != null) else {
  warn("Invalid player");
  return;
}

match (child) {
  BasePart p => BindPart(p),
  Model m => post("model spawned " .: m.Name),
  _ => warn("ignored instance")
};

observable int wallet = 100;
wallet.OnChange(func (int newValue) {
  post("Coins changed to: " .: newValue);
});

signal<Player, int> OnHit;
OnHit~>Connect(func (Player player, int amount) {
  post(player.Name .: " dmg " .: amount);
});
OnHit.Fire(player, 10);

array<string> names = {"Kartz", "Player1"};
dictionary<string, int> stats = { {"Coins", 100}, {"Gems", 50} };

spawn { task::wait(1); post("ready"); };
parallel { post("desync"); };

async Data FetchData(Player player) {
  return await DataService.Server.WaitFor(player);
}

[[server]]
void SaveData(Player player) { post(player.Name); }

[[client]]
void UpdateUI() { post("ui"); }

Inside Class::Method only: @this → self, @janitor → self.janitor. Not in void init(). Details: @this.

Fusion HUD uses Fusion.scoped, Fusion.Value, Fusion.Computed, Fusion.New. See examples/game.

What Cluaupp adds after clpp

• require(ClppLibs.X) → require(ReplicatedStorage.CluauppLibs.X)
• --!strict from cluaupp.config.json / #pragma strict
• out/ layout for Rojo (init, build, watch)
