This is the Nix flake update validator. A tool which is able to evaluate a flake at two points in history, check that everything evaluates, and provide a diff of the two. In its target state, it will provide a similar function to DeterminateSystems' awesome update-flake-lock tool, but with nvd integration and other bells and whistles that we've come to like.

How to Use

Currently, this only supports locally-stored flakes, although we are planning to add support for git-based URLs for usage outside of CI pipelines where the repository is already downloaded.

nix run git+https://nayeonie.com/ahuston-0/flake-update-diff-tool -- <flake path>

For use in other nix-based projects, flpudt is available as packages.${system}.flupdt. Please see our examples/ folder for common use-cases.

Why the name

flupdt comes from Fl(ake) Up(date) D(iff) T(ool). The cli is also available as flake-update-diff-tool, for ease-of-use and those who use screen readers or similar accessibility tools that may not react well to flupdt.
