Tabs let you define how big you want each indent to be, and spaces do not.

Spaces can too: Simply use more or less of them, to taste.

I have ADHD. Two spaces per indent makes it damn near impossible for me to scan code.

Then use four, or six, or eight, or 20. Hell, most code I’ve seen uses four spaces per indent anyway.

[Re: braille]

Surely there’s an editor out there that will automatically display indent spaces as a tab character. Or failing that it seems like it would be rather trivial create a program to convert n spaces to tabs, and vice versa.

As much as I sympathise with developers over headaches caused by themeing, I believe users (myself included) would be less up-in-arms about it if applications were less ugly by default. And boy howdy is libadwaita ugly as sin.

I’d be perfectly willing to tolerate a mismatched system, if the individual components looked at least okay. Like I’m not going to get e.g. steam or discord to match an e.g. Windows 9x theme, and I’m mostly okay with that because they aren’t horrible to look at. But, say, File Roller? Absolutely not. Horribly ugly.

Ough. Those must be some hefty test cases, even the deepest ones I tested (250 loops) completed in less than a tenth of a second. If its possible I may try to find a faster solution and resubmit later…

A bit late to the party but here’s a Rust solution that is probably maybe correct: https://pastebin.com/Eaes7hU9

Like last time, a brute force solution: checking if every substring is a set of well formed brackets, and, if so, recording it if its the longest seen so far.

Here’s an entry in Rust, though it feels quite a bit like cheating:

fn main() {
    let mut a = std::env::args().skip(1).next().unwrap();
    println!("{}", f(&mut a));
}


fn f(a: &mut String) -> String {
    let mut b = String::new();

    while *a != b {
        b = a.clone();
        *a = a.replace("{}", "").replace("()", "").replace("[]", "");
    }

    return b;
}

edit: added main function to take cli input.

Personally I quite like zstd, I find it has a pretty decent balance of speed to ratio at each of its levels.

Rust:

A super simple brute force attempt: https://pastebin.com/qbYQNQ7h

Also super slow. Took me a bit more than a minute for n=10.

edit: An updated version: https://pastebin.com/wVhxLmt9

Added some simple constraints to reduce the number of unfiltered entries that need to be generated, bringing the n=10 time down to 10ish seconds. EDIT: if any of the test cases are n=12 or greater, probably best to fail this without testing. It’s super inefficient memory wise.
