Yes, it is stable.

How can I avoid "value assigned to last is never read" warning from this macro? in c/[email protected]

  #[allow(unused_assignments)]

Thank you. This works!

It doesn't work, at least, on rustc 1.75.

Clippy didn't tell anything about the macro.

13 +         Some(cons_rc) => {
   |

To put #[allow(this_linting_rule)] like this:

    [ $x:expr, $( $y:expr ),* ] => {
	#[allow(unused_assignments)]
	{

I got error[E0658]: attributes on expressions are experimental.

To put it like this:

#[macro_export]
#[allow(unused_assignments)]
macro_rules! list {
    () => {
	None

It doesn't work.

Removing last will break my library.

#[macro_export]
macro_rules! list {
    () => {
	None
    };
    [ $x:expr, $( $y:expr ),* ] => {
	{
	    let mut first = cons($x, &None);
	    let mut last = &mut first;
	    $(
		let yet_another = cons($y, &None);
		if let Some(ref mut last_inner) = last {
		    let last_mut = Rc::get_mut(last_inner).unwrap();
		    last_mut.cdr = yet_another;
		    last = &mut last_mut.cdr;
		}
	    )*
	    first
	}
    }
}

This macro works as I expected because it can pass these tests.

    #[test]
    fn dolist() {
        let mut v = vec![];
        dolist!((i &cons(10, &list![20, 30, 40])) {
            v.push(i.car);
        });
        assert_eq!(v, vec![10, 20, 30, 40]);
    }

    #[test]
    fn turn_list_to_vec() {
        assert_eq!(list_to_vec(&list![1, 2, 3]), vec![1, 2, 3]);
    }

    #[test]
    fn count_elements() {
        assert_eq!(list_len(&list![10, 20, 30]), 3);
    }

However I got the warning "value assigned to last is never read."

How can I avoid this warning?

P.S. Full code

Mageia 9 released in c/[email protected]
[–] [email protected] 9 points 1 year ago

Because of the Redhat incident, I started to see people asking for community-based distros without a corporate that dominates the community. And, Mageia is one of them. So, I hope it will be more popular.

  • KDE is the default. So, for KDE users, Mageia with KDE was tested.
  • Mageia comes with Drake tools for configuring almost everything. IMO *drakes look quite friendly. Since they have been around for 20+ years, they must be stable.
  • Each release will be supported for 18 months, which is longer than Fedora.
What is the advantage of PKGBUILD over RPM specs? in c/[email protected]
[–] [email protected] 1 points 1 year ago

Such files are relatively easy to create and read, as they are basically shell scripts.

I agree. I lean towards writing in Bash script instead of learning yet another special-purpose language. Nonetheless, the RPM spec doesn't seem to pose any additional difficulty.

The immutability and configuration of Nix seems so appealing but at this point I’m really comfortable with Arch and it does everything I need in a pretty sane way so idk if I’d switch anytime soon.

Back in 2018, I had the experience of using NixOS. At that time, I noticed that the Nix language had a striking resemblance to Haskell, which stirred up feelings of anxiety within me.

One is that it’s a shell script,

Using Bash sounds convincing to me.

Do you also dislike openSUSE and openMandriva?

Will running nREPL on a Clojure application in a production environment result in a noticeable performance impact? (lemmy.one)
 

I anticipate that my application might encounter an issue that requires debugging or fixing using nREPL, but I'm concerned about the potential performance impact of using nREPL.
