 @petrichor:envs.net | so i've noticed that for a flake version-controlled with git, only files that are tracked by git are copied to the store, but if i use mercurial all files are copied regardless of whether mercurial knows about them or not | 13:08:49 |
| @petrichor:envs.net | is git the only "fully supported" dvcs in this way, or are there alternatives? mercurial is the only other one listed in the flakes manual as valid for a flake url | 13:11:28 |
| @petrichor:envs.net | i guess what i really want to know is: how can i tell nix that there are certain files in a flake on my local disk that should never be copied to the store, regardless of what vcs i'm using (or none)? | 14:13:21 |
 @ronnypfannschmidt:matrix.org | i wonder if .hgignore is respected, for git all added files are copied over , but mercurial doesnt have a index | 14:26:07 |
| @petrichor:envs.net | nope, sadly .hgignore is ... ignored ☹️ | 14:38:00 |
| @petrichor:envs.net | mercurial has no index, but it does have a concept of tracked/not tracked (aside from explicitly ignored files) | 14:38:25 |
| @ronnypfannschmidt:matrix.org | i presume its just not implemented for the nix integration then, unfortunately im no longer using mercurial | 14:50:28 |
| @petrichor:envs.net | nix doesn't truly respect the git index either, because it will include edits to a file that haven't be either staged or committed, as long as the path itself is staged or committed | 15:01:00 |

nix doesn't truly respect the git index either, because it will include edits to a file that haven't be either staged or committed, as long as the path itself is staged or committed my understanding is that this is intentional for development, the index is used to inform of the set of files, and mercurial is simply not matching that design or integrated | 09:31:56 |
| @ronnypfannschmidt:matrix.org | anyone aware if a way to declare a nixos system thats getting crosscompiled instead of build on binfmt? my x86_64 laptop is a tad slow on building stuff for my rpi andi wonder if i can build it faster that way | 09:57:46 |

anyone aware if a way to declare a nixos system thats getting crosscompiled instead of build on binfmt? my x86_64 laptop is a tad slow on building stuff for my rpi andi wonder if i can build it faster that way You could try cherry-picking some packages from e.g. pkgs.pkgsCross.aarch64-multiplatform | 09:59:06 |
| CRTified | But cross compiling everything is not necessarily favorable, as you will get cache misses (if you're targeting an architecture that gets cached) | 09:59:48 |
| @ronnypfannschmidt:matrix.org | is there a recommendd way to pick as much cached as possible? | 10:01:10 |
| CRTified | None that I am aware of | 10:01:57 |

| metasyntactic | I have a weird question about automatic updates with a flake for multiple machines: when I automatically update a flake periodically, it will update and commit a new flake.lock. What is the preferred way to do that for multiple machines that pull from a git repo for the flake to their /etc/NixOS clone of the upstream repo? Not commit flake.lock? Add scripts to constantly pull from master before updating? Have only one machine run flake update, push to master and just have the other machines rebuild periodically? What do people do? | 15:33:14 |
 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 | if it's not in the store, it's not part of the flake | 20:54:38 |
| 14 Aug 2023 |
| @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 |
