 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 |
 @rick:matrix.ciphernetics.nl | This one, I guess: https://news.ycombinator.com/item?id=34490376 | 18:28:30 |
| @linus:schreibt.jetzt | you got me :p | 18:29:44 |
| raboof | https://arnout.engelen.eu/nixos-iso-gnome-r13y/ / https://arnout.engelen.eu/nixos-iso-minimal-r13y/ are more recent (would be happy to work together on r13y.com) | 18:31:37 |

https://arnout.engelen.eu/nixos-iso-gnome-r13y/ / https://arnout.engelen.eu/nixos-iso-minimal-r13y/ are more recent (would be happy to work together on r13y.com) wow that's a lot of haskell libraries. I had forgotten that GHC object files are not reproducible. are there any recent developments about this? | 09:59:02 |
| @rnhmjoj:maxwell.ydns.eu | * wow, that's a lot of haskell libraries. I had forgotten that GHC object files are not reproducible. are there any recent developments about this? | 09:59:05 |
| atemu12 | Perhaps you could ask nh2, they're into GHC stuff | 10:00:03 |
| raboof | I didn't notice much activity in https://github.com/NixOS/nixpkgs/issues/151347 / https://gitlab.haskell.org/ghc/ghc/-/issues/12935 | 10:06:54 |
| raboof | though it seems it doesn't necessarily impact all haskell builds? there's quite some green ones in https://reproducible.archlinux.org/ | 10:09:53 |
| raboof | quick experiment: haskellPackages.void seems reproducible for us as well | 10:10:58 |
| @rnhmjoj:maxwell.ydns.eu | could it be related to parallel builds/optimisation level? | 10:11:21 |
| raboof | yeah single threaded builds seem more reliable but also quite a price to pay (https://github.com/NixOS/nixpkgs/issues/151347#issuecomment-997817696, https://gitlab.haskell.org/ghc/ghc/-/issues/12935#note_373865) | 10:13:26 |
