and if I do, it would read <nixpkgs-overlay> as well as NIXPKGS_CONFIG, in order to configure nixpkgs. And how would I best configure that with flake-based nixos config? you can set nixpkgs-overlay in nix.nixPath | 23:08:14 |

 bendlas | and what would I set that to, in this scenario? | 23:08:54 |
| figsoda | probably to the path that has your overlays | 23:09:11 |
| bendlas | In reply to @bendlas:matrix.org
Particularly, how would I best make it so that it takes the same configs and overlays, as configured through nixos modules? The wiki section I referenced, has stub files that do import <nixpkgs/nixos> {}, but that doesn't work so well with flakes ... . | 23:09:20 |

| figsoda | you would probably want to put it in a file | 23:11:47 |
| figsoda | otherwise you can do stuff like (builtins.getFlake "/path/to/your/nixos/config").nixosConfigurations.<name>.nixpkgs.overlays | 23:13:07 |
| figsoda | or (builtins.getFlake "/path/to/your/nixos/config").nixosConfigurations.<name>._module.args.pkgs | 23:13:57 |
| figsoda | * or (builtins.getFlake "/path/to/your/nixos/config").nixosConfigurations.<name>._module.args.pkgs if you want to overwrite <nixpkgs> | 23:14:07 |
| figsoda | you can replace /path/to/your/nixos/config with an interpolation of a relative path if that makes it easier | 23:15:03 |
| figsoda | and you can put that in a separate file or wrap it with a writeText or toFile | 23:15:42 |
| bendlas | that's not what I wanna do. but no problem. either I'll figure it out, or maybe someone who has solved this comes along .. | 23:17:58 |
| bendlas | Repeating this here: Does anybody have a working nixos flake config, that can share nixpkgs config and overlays between nixos modules and other nix tools doing import <nixpkgs>? | 23:21:28 |
| bendlas | * Repeating this here: Does anybody have a working nixos flake config, that can share nixpkgs config and overlays between nixos modules and other nix tools doing import <nixpkgs>? In a way similar to the Using nixpkgs.overlays from configuration.nix section in https://nixos.wiki/wiki/Overlays? | 23:23:03 |
| figsoda | In reply to @figsoda:matrix.org
otherwise you can do stuff like (builtins.getFlake "/path/to/your/nixos/config").nixosConfigurations.<name>.nixpkgs.overlays that's what this does | 23:25:33 |
| bendlas | I see. I was going in that direction (only with flake-compat), but couldn't test it so far because of unrelated difficulties. So I wondered if anyone already had something up. | 23:28:28 |
| bendlas | but I had a hunch that it would work like that, once I pushed it to a repo and didn't need --override-input any more -- which makes getFlake as well as flake-compat break in my test container | 23:32:32 |

 @peddie:matrix.org | hi, I tried to run nix develop on a flake-enabled repository and got error: A hash was specified for <package>, but there is no corresponding git dependency. in the flake.nix file in question, indeed I see a list of outputHashes but no other reference to the package in question (https://github.com/pola-rs/r-polars/blob/main/flake.nix#L23 arrow2-0.16.0). is this a flake problem? the specific command was nix develop github:Sicheng-Pan/r-polars | 02:48:47 |
| @peddie:matrix.org | same error with repo `pola-rs/r-polars` | 02:57:32 |
 kenji | Seems unmaintained, what happens if you remove the hashes?
| 06:34:40 |
| kenji | This doesn't seem like a flake specific problem.
| 06:35:04 |
| @peddie:matrix.org | ok thanks, opened an issue on github | 07:00:51 |
| @peddie:matrix.org | just didn't recognise that error message and initial googling suggested maybe flakes were associated with the error | 07:03:38 |
