Compiled. GC-free.

Cx is a compiled, GC-free systems language for game engines.

Cx is early. Expect breaks.

STATUS Release candidate

VERSION v0.1.0-rc

FOCUS Engines

hello.cx

name: str = "World"
age: t32 = 42
score: f64 = 9.8

print("Hello, {name}!")

What Cx is

Interpreter reference. Cranelift JIT active, parity-gated, incomplete.

THE CORE

No garbage collector. Explicit memory. Typed values. Small core.

THE STATUS

Interpreter is reference. Cranelift JIT is Phase 15 active: 155 fixtures, 66 PASS, 89 SKIP, 0 PARITY_FAILs.

Features

Interpreter surface is stable. JIT work remains.

NOW

Functions

Stable in the interpreter. Direct calls lower in the JIT.

Control flow

if/else and for lower. when JIT lowering is in progress.

Structs and methods

Struct fields lower. Method calls stay in progress.

Arrays

Fixed-size arrays work. JIT read/write fixtures pass.

Generics

Stable in the interpreter. JIT work remains.

Result<T>

Ok, Err, and ? work in the interpreter.

Imports

#![imports] resolves multi-file programs.

Testing

#[test], --test, assert, assert_eq.

Backend

Interpreter reference. Cranelift JIT active, parity-gated, incomplete.

LATER / IN PROGRESS

Type inference

Local inference works. Broader inference is in progress.

JIT gaps

when, methods, f64 ops, generics, Result, strings.

strref surface

Boundary type. Constructor syntax is unsettled.

C interop

Post-0.1.

Standard library

Minimal core first.
