Ahlang
Ahlang is a statically and strongly typed scripting language with a syntax very inspired by Rust. It's designed to be a general purpose scripting language that can be easily embedded in other Rust programs. Although performance is a major consideration, it's not expected to be able to compete in this aspect with other more established scripting languages like Lua.
Features
- Static typing
- Object oriented programming
- REPL
Syntax example
fn example(y: i32) -> str {
const x: i32 = 1;
let y: f64 = y as f64;
y += 1.2564;
let z = x + y as i32;
let a: bool = true;
if a && z > 0 {
print("Z is {}", z);
}
return "Hello, world!";
