What is Cm?

Cm is a modern systems programming language designed to combine the familiar syntax of C++ with the safety and powerful features of Rust.

Design Goals

1. Readability: Familiar syntax for C++/Java/C# developers.
2. Safety: Strong type system and modern memory management.
3. Performance: High performance through LLVM backend, comparable to C++.
4. Modern Features: First-class support for Pattern Matching, Generics, and Interfaces.

Core Features

1. Familiar Syntax

Based on C++ syntax, it eliminates unnecessary complexity while maintaining power.

2. High Portability

Supports multiple backends:

• Native: Executables via LLVM (x86_64, ARM64).
• WebAssembly: For browser-based high-performance applications.
• JavaScript: JS code generation for Node.js/browsers.
• JIT: For quick testing and scripting.

3. Strong Type System

Strict type checking prevents bugs at compile time.

4. Zero-cost Abstractions

Features like Generics and Interfaces are implemented without runtime overhead.

Example Code

int main() {
    println("Hello, Cm!");
    return 0;
}
