 azazel75 | 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 | well that is a shame | 15:55:26 |
| azazel75 | 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 | interesting, what about this last package containing only the names? does it also change? | 15:58:04 |
| azazel75 | it 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 | you can avoid that by cding to the directory before find | 16:00:18 |
| azazel75 | yes | 16:00:53 |
| mewp | 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 | it would be very weird for the hash to change without src changing | 16:02:45 |
| mewp | (none of this has anything to do with flakes btw, this would work the same without them) | 16:04:19 |
| azazel75 | find -type f . | sha1sum would expose only a difference in the names of the contents though | 16:08:54 |
| mewp | sorry, find -type f . | xargs sha1sum is what I meant | 16:09:50 |

| @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 |
| mewp | I don't use nix develop, so I'm not sure, but direnv with use flake definitely doesn't do that | 19:25:44 |
 tomberek | Do you have automatic GC turned on to run nightly? If so, a feature that might help you is "nix develop --profile ./tools". It makes a symlink to protect that stuff from GC. You can even enter that profile directly instead of the flake-defined one with "nix develop ./tools". | 20:11:57 |
| @abmantis:abcosta.com | ohhh, I do have GC running! | 20:23:23 |
| @abmantis:abcosta.com | I'll try that out! thanks a lot | 20:23:32 |
