The Chlang Programming Language

WARNING: This language is under development. Most features not implemented yet and can be changed in the feature. Use it at your own risk.

The main goal of this project is to create a statically and strong typed programming language. The language is inspired by Lua, Kotlin and Rust. It uses a register-based virtual machine like Lua

The register-based code can be used as an intermediate representation to generate code for native platforms like x86, ARM, etc.

Planned features:

• Variable, constant and function declarations
• Type checking and inference
• Function calls
• Control structures (if, while, for)
• Modules and packages
• Complex types (redesign type system and type environment)
• Data structures (arrays, vectors, user-defined structures)
• Interpreter for register-based virtual machine

Example

package main

const PI = 3.14159

struct Blog {
    title: string,
    content: string,
    likes: i32,
}

fn circle_area(radius: i32) -> f64 {
    return f64(PI) * radius * radius
}

fn multi_return(a: i32) -> i32, i32, f64 {
    return a, 2, 2.65
}

fn fibonacci_linear(n: i32) -> i32 { 
    let a = 0
    let b = 1
    for i in 0..=n {
        let c = a + b
        a, b = b, c
    }
    return a
}

fn main() {
    let radius = 10
    let area = circle_area(radius)
    let inside = if area > 100 {
        println("Area is greater than 100")
        true
    } else {
        println("Area is less than 100")
        false
    }
    println("Area: $area ($inside)")
    println("Fibonacci(10): ${fibonacci_linear(10)}")
    
    let a, b, c = multi_return(10)
    println("Multi return: $a, $b, $c")
}
