| bmabsout | Hello! I'm trying to run a function from flake so that the output is in a nix shell, I ended up doing things manually like this nix shell --impure --expr "(builtins.getFlake \"nixpkgs/nixos-21.11\").legacyPackages.x86_64-linux.python39.withPackages (p: [p.numpy])" is there a better way to do this? | 19:48:28 |
| bmabsout | Is there a way to do something similar in meaning to nix shell nixpkgs/nixos-21.11#python39.withPackages --something "(p: [p.numpy])", I might be getting a few concepts wrong here | 19:51:16 |

| bmabsout | Just found this! https://github.com/NixOS/nix/issues/5567 | 16:40:14 |
 flyx | iggybibi: in your Flake output, you can provide devShell and devShells, which you can then invoke with nix develop. is that what you're searching? | 16:42:56 |
| flyx | or if it's from an external flake, write a shell.nix that basically does what you've put in your command | 16:45:39 |
| bmabsout | Not really, I wanted a one liner like nix-shell -p 'python3.withPackages (ps: with ps; [ numpy scipy ])' | 16:46:08 |
| bmabsout | that drops me into a shell with python and these packages (or any lang with this setup) | 16:46:36 |
| flyx | I don't see where in the output schema a flake can provide functions in the first place | 16:51:15 |
| flyx | ah, they would be part of the python39 derivation that is queried | 16:53:16 |
| bmabsout changed their display name from iggybibi to bmabsout. | 17:05:23 |

Not really, I wanted a one liner like nix-shell -p 'python3.withPackages (ps: with ps; [ numpy scipy ])' I asked about this on Discourse, but I never got an answer: https://discourse.nixos.org/t/nix-shell-equivalent-of-nix-shell-p-arbitrary-expression/14832 | 00:50:18 |

 tomberek | anyone familiar with how a pure evaluation avoids "impure.nix" from nixpkgs? Context: i'm running nix inside of a container and getting:
error: access to absolute path '/.config/nixpkgs/overlays.nix' is forbidden in pure eval mode (use '--impure' to override)
it is a quite pure/minimal environment, but manually put together from a "scratch" starting point
| 01:51:51 |
| tomberek | hrm... it seems to stem from using the static nix | 02:21:36 |
| tomberek | i'm using variants around (Nix) 2.6.0pre20211217_6e6e998 and
nix (Nix) 2.6.0pre20211222_7feb741 with nix and nix-static to see why there is a difference. My thought was that "system" was not detected the same way with the static build... still investigating. | 02:44:29 |
| tomberek | okay, reproduced this on a normal NixOS machine using the same nix-static binary on an attribute that has not already been cached/built locally | 03:03:22 |
| tomberek | nix run github:nixos/nix#nix-static eval nixpkgs#coreutils.meta | 03:52:34 |
