Hi,

@henrirosten would it be possible to make nixmeta.csv customizable? We have custom derivations which are not published on nixpkgs, but we would still like them to get matched including metadata. A prominent example would be a custom terraform or custom ruby version, which is easily possible through mkTerraform or mkRuby constructors. Such custom versions are not gathered in the csv, since nixpkgs and default versions are scanned only.

https://github.com/NixOS/nixpkgs/blob/nixos-24.11/pkgs/applications/networking/cluster/terraform/default.nix#L184
https://github.com/NixOS/nixpkgs/blob/nixos-24.11/pkgs/development/interpreters/ruby/default.nix#L424

We would like to use nixtract to gather the data once per day (expensive operation, searching for derivations through nix eval and gathering meta elements). This data can then get converted into csv and should get referenced as metadata CSV:

Thank you!
