AERO

Write like Python, run like C++.
Aero 1.2.1 is now officially released — fusing C performance with Rust safety.

TIMELINE VERSIONS / HISTORY

What is it? A systems programming language.

Aero is a statically typed systems programming language.
Python-like syntax, compiled to native machine code by LLVM.
Generics · Type inference · Borrow checking — memory safety without a garbage collector.

THE LANGUAGE

Write like Python.
Run like C++.

The syntax is close to Python, and underneath, LLVM generates the machine code. Aero 1.2.1 adds Arena memory management and Vec dynamic arrays — done with GC and manual free, as safe as Rust, as fast as C. print is C's printf internally, with identical format placeholders.

$ aero run hello.aero
✓ JIT compiled and executed — output: hello world
$ aero build hello.aero
✓ AOT build complete — standalone exe: hello.exe
✓ 158 integration + 49 type-system tests all passing — TEST SUITE GREEN
arena.aero — Arena memory management
// arena.aero — region allocation, auto-reclaimed
arena MyArena {
data: [i32; 1024];
}
fn main() {
let mut arena = MyArena::new();
arena.data[0] = 42;
print("arena[0] = %lld\n", arena.data[0]);
// freed automatically when leaving scope, no manual free
}
vec.aero — Vec dynamic arrays
// vec.aero — safe dynamic arrays
fn main() {
let v = Vec::new();
v.push(10);
v.push(20);
v.push(30);
print("len = %lld, first = %lld\n", v.len(), v.get(0));
v.sort();
v.reverse();
}
