Hello, everyone!

I am here to present Flux, my new programming language.

It's statically typed, compiles to native binaries, and offers the power of C with the ergonomics of Python.

Here's Hello World:

#import "standard.fx";

using standard::io::console;

def main() -> int
{
    print("Hello World!");
    return 0;
};

Here's zero copy byte reinterpretation:

#import "standard.fx";

struct Packet
{
    data{8} type;       // unsigned by default
    data{16} length;
    data{32} timestamp;
};

def main() -> int
{
    byte[7] bytes = [0x01, 0x00, 0x20, 0x5F, 0x12, 0x34, 0x56];
    Packet pkt from bytes;  // Sugar for 'Packet pkt = Packet from bytes;'
    
    print(f"Type: {pkt.type}");
    print(f"Length: {pkt.length}");
    print(f"Time: {pkt.timestamp}");
    
    return 0;
};

Here's an example of bit slicing:

#import "standard.fx";

using standard::io::console;


def main() -> int
{
    noopstr x = "Testing!";

    data{4} as u4;
    u4 a = x[8``11]; // `` denotes bit range

    println(int(a));

    return 0;
};

This looks really interesting, especially the zero-copy reinterpretation and bit-level operations.

Out of curiosity, how are you handling memory safety with features like Packet pkt from bytes? Is there any validation layer, or is it intentionally low-level like C?

Also, do you have plans for tooling around the language (e.g. debugging or build system integration)? That’s usually where things get really interesting.

Nice work, looks like a fun project to follow.

There is a minimal validation, it is intentionally low level like C.

Yes I definitely plan to add debugging, a build system, and an LSP.

Thank you for the kind words!
