| tpw_rules | (mostly putting it here so i don't forget about it, don't know when i'll have time to address it if someone else wishes to) | 05:56:08 |
 Rick (Mindavi) | I suggest opening an issue on nixpkgs to keep track of long-term things :) | 06:58:10 |
 atemu12 | I also don't think that's a very high priority, is it? It's the VM for tests, it doesn't need to be bit-perfect. | 08:43:26 |

ran the iso-gnome report again: https://arnout.engelen.eu/nixos-iso-gnome-r13y/ . nice batch of things to look into. (note that this is the build closure, so it contains not only the things that are in the gnome iso, but also the things that are needed to build the gnome iso) hmm, a lot of them are duplicates of https://github.com/NixOS/nixpkgs/issues/151347 . I wonder if there's any easy way to convert derivation paths back to nixpkgs attribute paths (for those that have one), should probably be doable | 11:59:38 |

| atemu12 | raboof: Not that I'm aware of. | 12:41:06 |
| atemu12 | You could take a look at the drvs and filter out everything that has GHC in it/uses it to compile | 12:41:31 |
 @trofi:matrix.org | If you have a nixpkgs tree it should be easy. nix-env -qaP will print you both .drv and attribute. | 13:11:54 |
| raboof | Neat! Had to add --drv-path to get the full path. Unfortunately it doesn't recurse into haskellPackages... | 13:53:36 |
| @trofi:matrix.org | yeah, to fix the recursion you need to pass packages-config.nix that exposes hidden attributes: pkgs/top-level/make-tarball.nix: nix-env -f . -I nixpkgs=$src -qa --meta --json --arg config 'import ${./packages-config.nix}' "''${opts[@]}" >> tmp | 13:59:18 |

| @trofi:matrix.org | I use a similar hack locally to map .drv files back to attribute names and to repology package names: https://github.com/trofi/nix-olde/ | 14:01:19 |

I use a similar hack locally to map .drv files back to attribute names and to repology package names: https://github.com/trofi/nix-olde/ btw there is not nix code in that repo. Unsettling a bit. | 14:06:21 |
| raboof | trofi: makes sense, thanks | 14:07:49 |
| @trofi:matrix.org | I used --arg config 'import <nixpkgs/pkgs/top-level/packages-config.nix>'. Might work for you as is. | 14:08:35 |

btw there is not nix code in that repo. Unsettling a bit. Heh. I'll probably add a Cargo.lock file soon and will add simple .nix derivation for it. I don't really know rust ecosystem and I'm afraid it will get stale (will needs bots to update it and so on). | 14:10:18 |

I used --arg config 'import <nixpkgs/pkgs/top-level/packages-config.nix>'. Might work for you as is. error: attribute 'nodePackages_latest' missing - I might not have nix-env set up correctly though, I never use it | 14:11:25 |
| @trofi:matrix.org | I think -I nixpkgs=$src (as a path to the nixpkgs tree) should do it. | 14:12:18 |
| raboof | doesn't seem like it... | 14:18:01 |

 @linus:schreibt.jetzt | grahamc (he/him): do you think you could update r13y.com, or maybe let someone else take it over? I'd like to link it in a discussion on Nix and reproducibility, but it's currently 6 months old ^^ | 18:23:45 |

| @linus:schreibt.jetzt | you got me :p | 18:29:44 |
