 @dawnofmidnight:catgirl.cloud | * lixPackageSets.git is updated periodically, but it's not the same as lix-on-main (it's probably a couple of days behind), and you'll end up pulling the version of lix that nixpkgs has and the lix-on-main that you're using. aiui that mostly exists for folks who want the newest possible lix while still benefiting from the binary cache | 02:07:50 |

 somasis | what's the correct way to get pure evaluation when using nix repl? when not evaluating a flake, specifically. using --option pure-eval true doesn't seem to have an effect as builtins.currentSystem still returns "x86_64-linux" | 14:14:11 |

 hexa | --pure-eval? | 14:23:07 |
| somasis | didn't know that flag exists, but same result, builtins.currentSystem gives "x86_64-linux" :/ | 14:23:44 |

| somasis | huh... | 14:24:32 |
| somasis | hmm okay that's not good | 14:24:39 |
| somasis | hmm okay that's not good lol | 14:24:41 |
| somasis | I didn't think nix repl -f . would cause that to differ, yet it does | 14:25:17 |
| somasis | I didn't think nix repl -f . while in my config directory would cause that to differ, yet it does | 14:25:24 |
| hexa | I suppose accessing the filesystem like that is impure, that's why nix copies flake repos to the store before evaling 😄 | 14:26:44 |

| somasis | ah, yeah I guess it would have to do with that | 14:27:15 |
| hexa | can you say why you need a pure repl? | 14:27:37 |
 ekler | • --file ⟨#opt-file⟩ / -f file Interpret installables ⟨../../command-ref/new-cli/nix.md#installables⟩ as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression will be read from standard input. Implies --impure.
| 14:27:41 |
| hexa |
Implies --impure.
| 14:27:56 |
| hexa | right at the very end | 14:28:01 |
| ekler | yes, that's my point
| 14:28:14 |
| somasis | oops :) | 14:28:35 |
| somasis | today I've been playing around with trying to eliminate impurities from my config without using flakes. I've gotten there by trying nix flake check into doing its thing with a minimal flake.nix ({ outputs = import ./ {}; } and a well-written default.nix), but I wanted to poke around at it some more in nix repl | 14:29:47 |
