Hello again. Implemented Java like struct constructors which work like that:

import "std/memory.cup"

struct Foo{
	i: i32;
}

Foo(a: i32){
	let ptr: Foo* = malloc(sizeof(Foo));
	ptr.i = a;
	return ptr;
}

fn main(){
	let a: Foo* = new Foo(5);
	print(a.i);
}

Build Issue Environment macOS BigSur version 11.6

Description I was trying to follow the installation guide. I can't seem to build it on macOS BigSur.

What I did First of all, I googled this error.

$ ./meta/bootstrap.sh
[+] Compiling the bootstrap compiler...
ld: dynamic main executables must link with libSystem.dylib for architecture x86_64

https://stackoverflow.com/a/65570573

In accordance with this, fixed. (meta/bootstrap.sh)

   Darwin)
        cp bootstrap/macos.yasm bootstrap/cupcc.yasm
        yasm -f macho64 -o bootstrap/cupcc.o bootstrap/cupcc.yasm
        ld -o bootstrap/cupcc bootstrap/cupcc.o -macosx_version_min 11.6 -L /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -lSystem
        ;;

Then, I cannnot fix the next error.

$ ./meta/bootstrap.sh
[+] Compiling the bootstrap compiler...

Thanks for your great work. I would like to get the source code which produce the bootstrap assembly code.

Maybe you write the bootstrap code in C, Rust ..

Thanks.

Leverages /usr/bin/env to invoke yasm/ld from PATH. With this I can build the compiler on NixOS. The way this would work in libc is you would call execvpe instead of execve, which resolve the program to one that is found in PATH. I expect the final solution for this would be to add functionality in std to find a program in PATH. Once there's a way to access the environment variables that can be implemented.

First of all, i wanna thank you for this repo :) This is not a issue, but a question, since obviously you have more experience than me, and im just trying to find something.... I was searching for more repos like this, a kind of "programming language", but i literally found nothing, if you had to know some code that could help i will be thankful. ! I basically would love to have it in c/cpp, but anything can work !

Thanks for your time, and hope you reply soon :)

The "#!/usr/bin/env bash" shebang header is more flexible and works with more distributions. Using /usr/bin/env means bash will be selected based on PATH. This means different versions of bash can be used for each shell environment which is difficult when using a hardcoded globally share path like /bin/bash. This also makes it work on more distributions which don't use global shared paths like NixOS.

Maybe instead of using defer statements we can use with blocks:

struct A{
    a: i32,
}

fn new_a(): A*{
    ...
}

method A::close(){
    ...
}

fn main(){
    with let foo: A* = new_a(){
        ...
    }
}

Which essentially means:

struct A{
    a: i32,
}

fn new_a(): A*{
    ...
}

method A::close(){
    ...
}

fn main(){
    let foo: A* = new_a();
    ...
    foo::close();
}

I tried to compile the following program:

struct A{
	a: int;
	b: int;
	c: int;
}

fn a(): A{
	let a_: A;
	a_.a = 1;
	a_.b = 2;
	a_.c = 2;
	return a_;
}


fn main(){

}

Compiler tells me:
