Description of issue

Whenever I run brew uninstall --zap <app> the configuration files are not removed.

The files that should be removed are displayed in the CLI, but after the uninstall is finished, none of the files mentioned have been touched.

Relevant casks

All

[gromgit]

Generalizations like "Relevant casks: All" aren't useful input for debugging (and quite likely wrong). Can you show us the output of a actual brew uninstall --zap <cask>, during which you noticed the files not being removed?

Additionally, this is the PR where the zap for the plist was added: Homebrew/homebrew-cask@a433a85

At some point between gimp 2.8 and 2.10 they changed their application domain from org.gnome.gimp to org.gimp.gimp. Also, even if a little bit strange, the .plist and .savedState files have a colon/slash after the version number.

[gromgit]

I submitted a PR to fix the GIMP paths, and it's been merged. brew update, then reinstall GIMP and see if an uninstall now correctly trashes the indicated paths.

Well considering inkscape had the correct path the whole time and didn't work, nothing will have changed.

[gromgit]

Maybe, maybe not. You're already assuming both failed for the same reason on your system, when the GIMP cask had a clear issue that affects everyone.

Do you have a specific reason not to try?
