@ppenguin:matrix.orgppenguin I'm in the midst of fixing the "fallout" from removal of poetry2nix from nixpkgs for my xls2latex package, but I'm getting a bit confused (partly because of multi-layered flakes/shells). So now I have this flake, aiming to achieve the "sweet spot" of being compatible with non-flake usage (fetchFromGithub) and having the necessary flake outputs to do seamless development on it (repo devShell) and inclusion in user deployments, preferrably via overlay so the user can call it as a normal pkgs.xls2latex.

Now I'm looking for advice:

  1. whether the current flake structure is "best practice" for this case (notably defining the repo's package attr xls2latex via callPackage in let .. in and directly refering to it for the different flake outputs),

  2. secondly I get a strange errorr message in a consuming flake (see next)

The content of the nix path in the error is the default.nix from the xls2latex repo. (And the pandoc shell simply refers to the xls2latex package from pkgs for the build inputs.. 		14:45:47
@ppenguin:matrix.orgppenguinRedacted or Malformed Event15:05:54
@ppenguin:matrix.orgppenguin Following this pattern I managed to solve the error, the only funky thing(?) now is that I have flake outputs like this: overlays.${system}.default, which seems a bit unusual, but I need pkgs (system dependent) for the callPackage, so chicken & egg problem? 15:12:48

@jsimonrichard:matrix.orgSimon Richard I'm trying to use the development shell generated by the poetry2nix template, but when I run poetry add ... I get [org.freedesktop.DBus.Error.UnknownObject] ("No such object path '/org/freedesktop/secrets/aliases/default'",). Is this likely to be an issue with my host configuration, or is this a bug? (in case it's helpful, my host configuration can be found here: https://github.com/jsimonrichard/nix-config) 03:27:04
@julius:mtx.liftm.deˈt͡sɛːzaɐ̯

Simon Richard: Not entirely sure this is the same issue I had, but I have

          shellHook = ''
            export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring
          '';

on my dev shell…

03:48:15
@jsimonrichard:matrix.orgSimon Richard Thanks, that worked! However, the second time I ran nix develop I got the error attribute 'format' missing. I think it's being caused by the pypoetry.toml file or the poetry.lock file since those are the only files that have changed since the first time I ran nix develop. Any thoughts? 14:56:48

Hey all, is there a newer way to add overrides that isn't in the docs?

I keep getting errors that both poetry2nix.overrides and poetry2nix.defaultPoetryOverrides is missing from poetry2nix

14:31:48
@k900:0upti.meK900 Is poetry2nix your flake? 15:58:08
@k900:0upti.meK900* Is poetry2nix your flake input? 15:58:14
@k900:0upti.meK900Check the flake example in the repo 15:58:20

Is
poetry2nix your flake input?
It was my misunderstanding of how scope works in nix. I got past that, but now there are other problems :( 		15:58:06
