This must be run in a directory containing a PKGBUILD

Hello,

I updated my source.py from previous version of decman to newest as is shown in Readme as example and now I am getting this error:

[DECMAN] SUMMARY: The following foreign packages will be installed explicitly:

I see, something changed, I had to update git_url="https://github.com/kiviktnm/decman-pkgbuild.git",

But after this change it shows

I build it externally and ignoring it in source.py. Anyway it would be nice to have ability to just point to PKGBUILD file or repository holding it from source.py without replicating all that stuff about dependencies, build dependencies in both places and let it build / manage with it.

I think I know what the issue is. You probably had a different git_url in the beginning, which didn't have a PKGBUILD. However, decman stored the latest commit id of that repository as the latest reviewed version. Now that the git_url has changed, when decman tries to use git diff to show changes, it fails because the commit id doesn't exist in the new repository. The fix is to reset the stored commit id when git_url changes.

I'll implement the fix for this as soon as I can. My current life situation doesn't leave me with a ton of time, so it may take a while.

I'll provide instructions to reset the stored commit id manually tomorrow or during the weekend since I'll have time then.

As for the feature request, to just point to a PKGBUILD file, I'll look into that, since it will improve the user experience.

Exactly as you deducted! Thank you, no rush, take your time, life is more important! I am grateful for your tool because it allowed me to leave Guix (because of GNU only approach and lots of old packages, problems with rust, npm, ...) and NixOS (because of NIX DSL which I wasn't able to understand). Arch + Decman is ideal setup for me.

If the issue is the one I suggested, this should be a manual way to resolve it.

You'll have to edit the file /var/lib/decman/store.json. In that file, there is a dictionary pkgbuild_git_commits. Remove the entry "decman-git": "<some hash>".

Before:

{
  <snip>

  "pkgbuild_git_commits": {
    <possibly other entries>
    "decman-git": "10d10e816b474404545905e4cef894775acc2a0f"
  }
}

After:

{
  <snip>

  "pkgbuild_git_commits": {
    <possibly other entries>
  }
}
