From a non-technical user’s pov kinda true.

But not true at all when you enumerate the actual responsibilities of an OS.

The terminal

Not really. Today at work that error appeared to me. As a software developer of course I have access to terminal, I use it every day.

I just closed the message and opened the terminal again, and it worked.

This is Microsoft’s fault, not any other’s.

Same thing with git.

There is no shortage of git beginners that refuse to use a GUI.

They ask for help for something, I haven’t used git CLI in years, so I tell them “go to this place and click those button”, then they open the vscode terminal and ask “but can I do it from CLI?” Okay then I go to search the command. Meanwhile I tell them to checkout a branch or something as basic as that and watch them struggle for way longer than it took me to find the command I was looking for.

I get that thousands of elitists have convinced you that using git from a GUI is a sin. But it’s fine, I won’t tell no one. I use a GUI myself.

The C example is the wonderful happy path scenario that only manifests in dreams.

Most projects don’t have a dependency list you can just install in a single apt command. Some of those dependencies might not be even available on your distro. Or there is only a non-compatible version available. Or you have to cast some incantation to make that dependency available.

Then you have to set some random environment variables. And do a bunch of things that the maintainers see as obvious since they do it every day, so it’s barely documented.

And once you have it installed, you go to run it but discover that the fantastic CLI arguments you found online that would do what you installed this program to do, are not available in your version since it’s too new and the entire CLI was reworked. And they removed the functionality you need since it was “bad practice and a messy way to do things”.

All of this assuming the installation process is documented at all and it’s not a “just compile it, duh, you should know how to do it”.

In my case, I don’t usually encounter cases where I can’t just ?. But when I do, just make an error enum (kinda like thiserror) that encapsulates the possible errors + possibly adds more.

On the call site, just convert to string if I don’t care about specifics (anyhow-style).

I don’t find this much painful.

Concise: not much on the declaration side, since you have to create an entire enum for each function in worst-case scenario. But on code side, it’s just .map_err(MyError)?.

Type-safe: can’t beat errors as enum values wrapped in Result.

Composable: i don’t think you can beat rust enums in composability.

I don’t use anyhow/thiserror, so I’m not sure. But I believe thiserror fixes the conciseness issue for this.

“not having mandatory parenthesis in if statements is hazardous, so I prefer to write C instead of rust, because I really care about safety” < that’s how you sound.

Rust allows you to choose whatever method you want.

• Early return propagating the error
• Early return ignoring the error (maybe by returning a default value)
• Explicit handling by if-else (or match) to distinguish between error and not error cases.
• Early return and turn the error into another type that is easier to handle by the caller.
• Assume there is no error, and just panic if there is. (.unwrap)

There are only 2 error handling methods that you cannot do:

• Exceptions
• Ignore the error and continue execution

And that is because both of them are bad because they allow you to do the second one, when .unwrap is just there and better.

If your concept of “not ugly” is “I just want to see the happy path” then you either write bad code that is “not ugly” or write good code that is “ugly”. Because there is no language that allows you to handle errors while not having error handling code near where the errors are produced.

Most of the times you can just let ... else (which is basically a custom ? if you need if let ... else it’s because you actually need 2 branching code paths. In any other language you also do if ... else when you have 2 different code branches. I don’t see why this is a rust-specific issue.

I’d say it’s much more influential the names of the identifiers of the standard library.

A language with function keyword that names it’s stdlib functions strstr and strtok will inspire way worse naming than on that has fn keyword with stdlib functions str::contains and str::split.

We could search for a random crate on crates.io and see what identifiers people actually use, or we could spread misinformation on Lemmy.

You used macro_rules, which is not common at all. Most rust files don’t contain any macro definition.

This code doesn’t even compile. There is a random function definition, and then there are loose statements not inside any code block.

The loop is also annotated, which is not common at all, and when loops are annotated it’s a blessing for readability. Additionally, the loop (+annotation) is indented for some reason.

And the loop doesn’t contain any codeblock. Just an opening bracket.

Also, the function definition contains a lifetime annotation. While they are not uncommon, I wouldn’t say the average rust function contains them. Of course their frequency changes a lot depending on context, but in my experience most functions I write/read don’t have lifetime annotations at all.

Yes, what you wrote somewhat resembles rust. But it is in no way average rust code.

Not to be confused with glibc. Where the g does actually stand for gnu.

But they can’t say “I’m going to rewrite this in that other language” because that’s the thing they hate about rust, so if they said that it would be too obvious that they’re full of shit.

Any body could just go to down detector. And of course effectively check the status of cloud flare based on if downdetector shows this page themselves.

My M turned upside down. I’m leaving it like this

The newest windows terminal is called “terminal”.

I used to type “cwd”, but after installing terminal, I type “terminal”. Probably same situation for OP.

My comment explicitly avoids the “standard” problem.

A user could have many "theming system"s installed at once, while only having 1 DE. The user ideally would configure only one, and some program should try to translate that system into the other ones.

Then each app will fetch the list of theming systems the user has installed, and choose whichever the app prefers. And if there’s no match, fall back to a default hard coded theme.

Except accept/cancel is sometimes switched.

As a PC gamer that doesn’t often use a controller. I often have to enter menus twice. Once to just exit it, and another to accept whatever is the first entry.

Specially when emulating old Nintendo games, which don’t say which button is which.

This can also be a side product for code blocks being expressions instead of statements.

In rust for example they are, so it’s not rare to see functions like:

fn add_one(x: i32) -> i32 {
    x+1
}

This lets you do amazing things like:

let x = if y < 0.0 {
    0.0
} else {
    y
}

which is the same as x = y < 0.0 ? 0.0 : y

But is much better for more complex logic. So you can forget about chaining 3-4 ternary operations in a single line.

I’ve got all that. I just needed to convert a string of characters into a list of glyph IDs.

For context, I’m doing a code editor.

I don’t use harfbuzz for shaping or whatever, since I planned on rendering single lines of mono spaced text. I can do everything except string->glyphs conversion.

Just trying to implement basic features such as ligatures is incredibly hard, since there’s almost no documentation. Therefore you can’t make assumptions that are necessary to take shortcuts and make optimizations. I don’t know if harfbuzz uses a source of documentation that I haven’t been able to find, or maybe they are just way smarter than me, or if fonts are made in a way that they work with harfbuzz instead of the other way around.

As someone trying to have as little dependencies as possible, it is a struggle. But at the same time, harfbuzz saved me soo much time.

EDIT: I don’t do my own glyph rasterization, but that’s because I haven’t gotten to it yet, so I do use a library. I don’t know if it’s going to be harder than string->glyphs, but I doubt so.
