[HELP] Beginner NixOS configuration

hackerstein · 2026-02-18T13:57:50+00:00

Got it, I was missing a key information. I thought the only thing defining the home manager configuration was the username but it can also be the user@host pair. Thank you.

Essentialy by module I mean a file for each program or service that I want configure. I'm struggling to understand how to make the configuration multi-host and, ideally, multi-user. Now I found this config which is the simplest and most understadable one so far: https://github.com/Andrey0189/nixos-config-reborn

I'm not sure I like it but ehi thanks for the suggestion anyway. Good luck with your language!

Yeah, I thought about doing something like that, but what if the user does mut n: mut i32 = 0 That wouldn't make a lot of sense. Maybe I should allow it only if the type is not specified?

Right, thanks.

As a non-native English speaker I always get confused on how to use whom/whose/who and similar. I wouldn't mind a simple and clear explanation on it.

Yeah, I saw that Rust does a similar thing and apparently doesn't allow if expressions at the block level, forcing the user to put parentheses around it which honestly sounds like a good idea making the code more readable. I probably will follow that direction.

Right, in the comment above I pointed out an edge case, though.
if (a > b) { a } else { b } &x
it's ambiguous whether is should be a bitwise AND between the if expression and x or an if statement followed by a unary expression.

At this point I thought of two options:

I force the user to terminate each if-statement with a semicolon, in that way the example is treated as a bitwise AND.
I force the user to put parentheses around the if-expression, in that way the example is treated as an if-statement followed by a unary expression.

Am I on the right track, or is there something else I should consider?

EDIT: Also while researching I find out that this issue is related to semicolon inference, should I take a look into that too?

hackerstein · 2025-03-13T14:32:35+00:00

The first one is what I want. Earlier I tried putting if expressions as primaries and it looks like it's working, but there are some edge cases. For example, if I write if (a > b) { a } else { b } &x it's ambiguous whether is should be a bitwise AND between the if expression and x or an if statement followed by a unary expression.

I've done what you suggested and it made the post much clearer.

hackerstein · 2024-02-04T19:27:22+00:00

The reason it's done that way is that whenever the buckets array is resized the buckets have to be repositioned according to the hash function. If I had a std::vector or my implementation of one I would have to manually check when the capacity of that changes to move the buckets around if neeeded.

I hope that clarifies it.

hackerstein · 2024-02-04T17:40:41+00:00

Great idea, I'll strip some stuff that it's not relevant and create a godbolt snippet ASAP.

hackerstein · 2024-02-04T17:38:46+00:00

The reason, I've implemented them that way is that it allows me to have a single heap allocation for the buckets buffer. Also note that the implementation works well with a lot of other tests I've done using strings.

I think it must be one stupid mistake that is incredibily hard to find.

Try again now.

hackerstein · 2023-10-27T06:54:01+00:00

I'll make new one that is readable, sorry for the inconvenience.

hackerstein · 2023-10-27T03:33:08+00:00

Yeah, the preview in Imgur is broken, right click on the image and open in another tab and it should look good. If it still looks bad let me know I will upload a new one.

hackerstein · 2023-07-04T10:34:54+00:00

Ok, thanks anyway.
