A new hobby programming language for OS developement?

Just came up with this and wanted some feedback on it. I was just rewriting various assembly programs I've written with more C or Rust like syntax. I'm mostly just doing this for fun and for myself and accept that there are various reasons not to try and replace assembly with a programming language in OS developement. The idea is that this would simultaneously replace C and assembly. I also want it to be describing whats actually happening rather than abstracting it away as much as is reasonable. Reasonable being kind of arbitrary.
Code: Select all
// HELLO WORLD EXAMPLE
const MESSAGE:[b8] = "Hello World";
func main() -> sys_exit {
stdout = MESSAGE;
return 0;
}
// PART OF KERNEL MAIN EXAMPLE
func error(val: b8) -> hlt {
0xb8000 = "ERR: ";
0xb800a = val;
}
func check_multiboot() {
if (eax != 0x36d76289) {
error("M");
}
return;
}
func main32() -> hlt {
check_multiboot();
}
// MULTIBOOT HEADER EXAMPLE
#pragma section .multiboot_header
#define MULTIBOOT2 0xe85250d6
#define i386 0
#define FRAME_BUFFER_TAG 5
{
const MAGIC:b32 = MULTIBOOT2;
const ARCHITECTURE:b32 = i386;
}
{
const TAG_TYPE:b16 = FRAME_BUFFER_TAG;
const OPTIONAL:b16 = 0;
const WIDTH:b32 = 500;
const HEIGHT:b32 = 500;
const DEPTH:b32 = 32;
}
{
const END0:b16 = 0;
const END1:b16 = 0;
const END2:b16 = 0;
}

It doesnt seem too bad, the only problem is actually creating a compiler for that language

Congrats on starting your own language!
You've got a few inconsistencies:
In the first line, you're assigning to the memory in '0xb8000'. In the second line, you're treating 0x36d76289 as a number literal.
Are you assigning a variable? If this is a function call, how do you assign a variable?
I like putting the the type after the declaration. It actually makes implementing the parser a little easier.
How do you now 'eax' doesn't get clobbered during the function call to check_multiboot?
Are you trying to invent a high level language (e.g. C?) or trying to invent a
high level assembler?
You might be able to start by writing a assembly processor, where you replace mov with =, e.g.:
and replace local stack locations with typed variables?

Good one.
Generally speaking, pick
one project. Language, standard library, OS kernel, version control system, ... -- if you work on more than one of those, you're just more likely to fail at all of them.
You don't invent a better hammer
in order to make a better sword. You might invent a better hammer, because you feel the ones available aren't good enough. Only when the hammer is done and has proven itself,
then think about what your next project might be.
