| xgwq | Hi, I currrently try to package a go package that fetches the version from Buildinfo like this
func GetVersion() (ret string) {
if b, ok := debug.ReadBuildInfo(); ok && len(b.Main.Version) > 0 {
ret = b.Main.Version
} else {
ret = "unknown"
}
return
}
Building that with nix gets (devel) as version, how can I set the version to the real package version?

 Diamond (it/she) | you could look into fetchgit with preserving .git | 22:14:48 |
| Diamond (it/she) | https://discourse.nixos.org/t/keep-git-folder-in-when-fetching-a-git-repo/8590 | 22:15:04 |
| Diamond (it/she) | https://pkg.go.dev/cmd/go -buildvcs=true will also enforce this | 22:21:49 |
| Diamond (it/she) | which you should have that set | 22:21:52 |
| xgwq | This seems to go in the right direction but does not find the tag to get its version from and instead results in v0.0.0-20250719172851-d68c15f4dc17+dirty. | 23:52:25 |
| xgwq | Adding preBuild = "git tag v${version}"; adds the right version but still keeps the +dirty. | 23:55:46 |

| Diamond (it/she) | fetchTags = true i think | 03:29:11 |
| Diamond (it/she) | although that dirty seems to be because nix patches the package maybe? | 03:29:19 |
| Diamond (it/she) | it's doing something w the repo | 03:29:27 |
| Diamond (it/she) | you can do preBuild = "git status;"; and see | 03:29:36 |
 Paul Meyer (katexochen) | using fetchgit will result in the source not being reproducible, as it is not possible to get .git deterministic at this point.
I'd suggest to apply a patch or substituteInPlace to make it return the correct version. | 09:16:08 |
| xgwq | That does it. The dirty comes from nix deleting half the repo and untracking the other half. | 10:30:03 |

 Alyssa Ross | In reply to @diamondburned:matrix.org
is that true? pkgs.fetchgit still has to be hash locked afaik yes but that hash changes sometimes | 18:51:14 |
| Alyssa Ross | it's bad | 18:51:24 |
| Alyssa Ross | if you set leaveDotGit | 18:51:24 |

I'm looking for a bit of help for compiling this Go software: https://github.com/NixOS/nixpkgs/pull/427193 (https://github.com/buildpacks/pack). The issue started to appear after they did this: https://github.com/buildpacks/pack/pull/2390
When I run the build, it end up with:
