Cloth

Cloth is a statically typed language for portable native programs. It combines classes, interfaces, and value types with managed memory and explicit nullability.

// Main.co
static func Main() {
  println("Hello, Cloth!");
}

Every .co file defines a type named after the file. Main.co defines Main; you do not repeat the name in a class declaration. Packages follow directories beneath your source root. Names beginning with an uppercase ASCII letter are public; lowercase and underscore-prefixed names are private.

Classes, strings, and arrays use garbage-collected references. Structs and enums are values. References are non-null by default; write T? when absence is part of your data.

Start learning

1. Install the toolchain.
2. Write and run Hello World.
3. Learn files, values, and functions.
4. Build a program with multiple files.

The language reference explains the supported syntax and semantics. Tools and projects covers clothc, Shuttle manifests, and local dependencies.

Reading the examples

Code blocks marked cloth contain Cloth source. A comment such as // User.co identifies the filename required by a type declaration. Short statement examples belong inside a function unless otherwise stated.

Cloth is under active development. These pages describe implemented behavior, including native structs, and state relevant limitations where you encounter them. A complete standard library, remote package registry, generics, and recoverable exceptions are not currently available.
