 dminca | Hi everyone, I'm facing an issue when trying to add more nixpkgs urls to my inputs within my flake. I'm on aarm64-darwin
https://codeberg.org/dminca/nix-config/commit/e3802ac776b6829dcf1427581d1e02af05123339
Does anyone know what might've caused this? you think pinning the *-unstable channel to -23-11 could cause such problems?
| 10:24:04 |
| dminca | I forgot to run nix flake update beforehand ... otherwise the rebuild wouldn't have been aware of the new inputs right 🤦♂️ | 10:29:02 |
| dminca | alright this was a catastrophe ... seems the nixos-23-11 branch lacks zsh autosuggestions flag, therefore I just reverted back to nixpkgs-unstable ... | 11:27:26 |
| dminca | * alright this was a catastrophe ... seems the nixos-23-11 branch lacks zsh autosuggestions flag, therefore I just reverted back to nixpkgs-unstable ...
However I'm not sure if this is coming from me pinning nixpkgs or from pinning home-manager https://codeberg.org/dminca/nix-config/commit/decaf43182f8eaf4f4c92ebaf5d78755e72707f1#diff-58cb4f58166586c1ed7f076c568d41682df3661c

| sam | What commit of nixpkgs does nix build nixpkgs#foo use? | 11:37:04 |
 Jassuko | Current version of the channel your system or user environment has? | 12:31:53 |
| sam | How does that relate to nix registry? | 12:32:37 |
| sam | If that's the case, why does nix build --eval 'expression containing <nixpkgs>' require the --impure flag, but nix build nixpkgs#foo does not. Is it somehow pure? | 12:34:45 |
| sam | Docs say: --impure: Allow access to mutable paths and repositories., so does nix build nixpkgs#foo not use the mutable paths? | 12:35:48 |
| sam | I'm a little bit confused on the difference between registries and channels, and which are considered immutable | 12:36:20 |
| sam | Also, if that's the case, why does nix build sometimes fetch nixpkgs from GitHub, even though the channel hasn't changed? | 12:37:08 |
| sam | I believe I have a case on my machine where nix build nixpkgs#foo works, but nix-build <nixpkgs> -A foo does not work (build error) | 12:39:05 |
| sam | nix build --impure --expr '(import <nixpkgs> {}).foo' also encounters a build error. How can this kind of error be reproduced on another machine? | 12:45:27 |

I'm a little bit confused on the difference between registries and channels, and which are considered immutable Your confusion is understandable, because this is, imho, a major design flaw in the flake registry. Unlike channels the online flake registry doesn't even require a user command to mutate, it simply does | 14:50:54 |
| Qyriad | On NixOS unstable, and the next NixOS release, this issue will be worked around to be much less confusing; flake:nixpkgs and <nixpkgs> will both point to the nixpkgs your system was built with: https://github.com/NixOS/nixpkgs/pull/254405 | 14:52:19 |

Your confusion is understandable, because this is, imho, a major design flaw in the flake registry. Unlike channels the online flake registry doesn't even require a user command to mutate, it simply does this is my favorite commentary on the mutable state hidden in the Nix registry:
nix.settings.flake-registry = __toFile "begone-evil.json" (__toJSON { flakes = [ ]; version = 2; });

| @axolotl:the-apothecary.club | could someone explain why the expression at https://codeberg.org/shitpostalotl/bespoke/src/branch/main/pkgs/greenfield.nix#L7 evaluates to false? the situation is that a flake input representing greenfield's source repo is passed as an arg to the derivation as fsrc. as you can see, i'm trying to reference a file in the source repo by path. however, fsrc always evaluates to a nonexistant "nix" subdirectory in the source, while any functions which take it as an argument always return the store path of that flake instead of fsrc | 05:26:13 |
