did some evening hacking on my derivation diff utility and experimented with the output format a bit more. It now shows whether an input has been added, removed or updated and if updated whether that's because of a version bump (v) or a hash change without a version bump (h). Haven't pushed the current version to codeberg yet, as I'm still trying out new ideas, learning about more and more #guix internals that simplify what I'm trying to do along the way, and the codebase is a mess because of that! (hope to abandon this hacky learning project utility in favor of a prospective guix store diff command in guix proper one day)

a screenshot showing the output of my drv-diff utility diffing two derivations of the IRC client senpai. It shows:

A (senpai-0.4.1.drv): 629 (only A: 19, shared: 610 = 96.98%)
B (senpai-0.4.1.drv): 634 (only B: 24, shared: 610 = 96.21%)
A ∪ B: 653 | A ∩ B: 610 | Diff: 43 | IoU: 0.9342 93.42%

and it also shows a diff-tree that tries to give context why exactly the derivation DAG has changed.

i think it's beautiful that every upgrade of a rust application *has* to include at least one ASCII art homage to an F-Zero vehicle* in its tree diff

* if anyone wants to take guesses which one is shown here -> https://mutecity.org/wiki/Machine
