Revert dependencies graph

Hello, Guix Help! Updating with `guix pull` and `guix package -u` has made me waiting for 3 hours already. webkitgtk is compiling so long.
I've checked all browsers I have and found this is epiphany that needs webkitgtk

$ guix package --show=epiphany | grep gtk
+ gnome-desktop@3.24.2 gsettings-desktop-schemas@3.24.1 gtk+@3.24.0
+ sqlite@3.24.0 webkitgtk@2.22.4
But I have not found in manual revert dependencies graph.
Does Guix can show revert dependencies? I want only type something to check what the package needs webkitgtk.

Please, let me know if Guix shows revert dependencies of installed packages?

I had the same issue, but with qtwebkit.  Maybe this could help:
--8<---------------cut here---------------start------------->8---
for i in $(guix package -I | awk '{print $1}') ; do guix graph $i | grep -q qtwebkit && echo $i ; done
--8<---------------cut here---------------end--------------->8---

Oleg.

Guix calls "reverse dependencies" "dependents".  You can list them with:

--8<---------------cut here---------------start------------->8---
> guix refresh --list-dependent webkitgtk
Building the following 2 packages would ensure 3 dependent packages are rebuilt: eolie@0.9.45 gnome@3.24.3
--8<---------------cut here---------------end--------------->8---

Hope that helps!

`guix graph` can show the reverse dependency graph of a package. It does
not show the intersection of that graph with your installed packages,
but it still will help:

`guix graph --type=reverse-package webkitgtk | dot -Tsvg > ~/out.svg`

And then open the SVG image of the graph to view it.
