@mewp:nurupo.pl@mewp:nurupo.pl such as find . > $out 15:14:12
@mewp:nurupo.pl@mewp:nurupo.pl(there are probably better methods, just none of them come to mind right now)15:14:59
@azazel75:matrix.orgazazel75thanks, I'll try to do that15:15:35
@azazel75:matrix.orgazazel75gitIgnoreFilterWith is https://github.com/hercules-ci/gitignore.nix/blob/master/find-files.nix#L2415:16:34

@cabalcrow:matrix.orgCabalCrowis there a way to force nixos-rebuild to copy .git folders into the store directory?15:48:25
@mewp:nurupo.pl@mewp:nurupo.plyou could likely create a package with the current configuration repo if that's what you want. no built-in module for that afaik15:50:07
@azazel75:matrix.orgazazel75

so, i did what you suggested mewp , whit a new package like:

          pkgsSrcContents = pkgs.stdenvNoCC.mkDerivation {
            name = "src-contents";
            src = pkgsSrc;
            builder = pkgs.writeText "builder.sh" ''
              ${pkgs.findutils}/bin/find $src >> $out
            '';
          };

@cabalcrow:matrix.orgCabalCrowwell that is a shame15:55:26
@azazel75:matrix.orgazazel75 it turns out that even if flake.nix isn't in the resulting $src, if I change it between two runs the hash of that $src store path will change 15:57:12
@mewp:nurupo.pl@mewp:nurupo.plinteresting, what about this last package containing only the names? does it also change?15:58:04
@azazel75:matrix.orgazazel75it changes because the path of $src changes... I should calculate a checksum of the whole contents of $src, maybe with a volatile tar command..15:59:35
@mewp:nurupo.pl@mewp:nurupo.pl you can avoid that by cding to the directory before find 16:00:18
@azazel75:matrix.orgazazel75yes16:00:53
@mewp:nurupo.pl@mewp:nurupo.pl then you'll be able to see if the list of files changes. you can also do find -type f . | sha1sum to see if the hashes differ 16:02:10
@mewp:nurupo.pl@mewp:nurupo.plit would be very weird for the hash to change without src changing16:02:45
@mewp:nurupo.pl@mewp:nurupo.pl(none of this has anything to do with flakes btw, this would work the same without them)16:04:19
@azazel75:matrix.orgazazel75 find -type f . | sha1sum would expose only a difference in the names of the contents though 16:08:54
@mewp:nurupo.pl@mewp:nurupo.pl sorry, find -type f . | xargs sha1sum is what I meant 16:09:50

@abmantis:abcosta.com@abmantis:abcosta.com Hey! Why is it that when I use nix develop (on some repo I've used already) it fetches and updates the packages automatically? It takes quite a while, and I would be happy most of the times to use the current packages I already used one day ago. any way to stop that? 19:24:06
