 Charles | you could have a scheduled/periodic CI run that bumps flake.lock and then have all machines pull and rebuild | 20:37:43 |

 @petrichor:envs.net | is there a way to tell nix never to copy a given file into the store from a flake, that isn't dependent on the vcs being used? | 12:24:00 |
 @antifuchs:asf.computer | I tend to use the various source-cleaning functions for that, e.g. https://github.com/NixOS/nixpkgs/blob/master/lib/sources.nix#L26 | 16:54:21 |
| @antifuchs:asf.computer | requires that any references you make are based on pre-cleaned trees already, so it's not fully easy tbh | 16:54:50 |

is there a way to tell nix never to copy a given file into the store from a flake, that isn't dependent on the vcs being used? every file in a flake is in the store. | 20:54:29 |
| @ulli:hrnz.li | if it's not in the store, it's not part of the flake | 20:54:38 |

| @petrichor:envs.net | OK, so I want to be able to tell nix that not every file in the source tree while I'm developing it is part of a flake | 09:00:10 |
| @petrichor:envs.net | that's easy with git, but I don't know how to do it with any other vcs (or none) | 09:00:38 |
| @petrichor:envs.net | e.g. maybe a .flakeignore file, a la .dockerignore? https://docs.docker.com/engine/reference/builder/#dockerignore-file | 16:31:21 |

 lxsameer | hey folks, is it possible to have multiple devShells for a platform? for example, one with glibc and one with musl under linux? | 22:21:46 |
 Ilan Joselevich (Kranzes) | Yep, the flake schema is devShells.x86_64-linux.X | 23:04:46 |
| Ilan Joselevich (Kranzes) | devShells.x86_64-linux = {
clang = pkgs.mkShell.override { stdenv = pkgs.clangStdenv; } {
packages = [ pkgs.hello ];
};
gcc = pkgs.mkShell {
packages = [ pkgs.cmatrix ];
};
};
| 23:11:05 |
| Ilan Joselevich (Kranzes) | devShells.${system} is an attrset | 23:11:17 |
| Ilan Joselevich (Kranzes) | what's the musl stdenv that I don't know | 23:11:59 |
 CRTified | In reply to @kranzes:matrix.org
devShells.x86_64-linux = {

Where's pkgs coming from there? | 23:21:53 |
