Package request: repology

[panicgh]

Project description

Repology is a packaging hub, providing users with comparisons of statistics of packages. For example, which pkgs are available in which versions and repositories.

I would find it interesting to run my own instance of repology, scraping e.g. company internal (RPM, DEB) repositories, GitLab for new version tags etc. This would allow for easy comparison of available packages and versions. For example the organization may run its own customized Linux distro (e.g. spun-off Debian; using regular snapshots of upstream repos) with branches for the integration of internal software (e.g. stable, testing/development versions of the distro).

This would need packaging of the software components of repology as well as NixOS modules.

I created a basic flake for repology for dev testing, could probably be of help while creating a package in nixpkgs
