How can I purge *all* settings?

[tomicakorac]

Question:
How can I remove any and all traces of Foliate having ever existed on my system?

The issue I'm facing:

• I uninstall Foliate (apt purge foliate)
• I search system-wide for *(F|f)oliat* and permanently delete each and every instance of found results
• I re-install Foliate (apt install foliate)
• My old app settings are magically back!

I want to nuke all of Foliate data and make a clean install. How can I do that? Which are all the places that Foliate uses to store config, cache, data and any other traces of its existance?

Version:

• Foliate version: Latest
• OS/Distribution and version: Ubuntu 22.04
• Desktop environment: GNOME Shell 42
• Installation method: PPA

Run gsettings list-recursively com.github.johnfactotum.Foliate.

Or use dconf Editor, navigate to /com/github/johnfactotum/, right click on Foliate, and select "Reset recursively".

Thank you.

gsettings list-recursively com.github.johnfactotum.Foliate
No such schema “com.github.johnfactotum.Foliate”

list-recursively was a typo. Should be reset-recursively.

"No such schema" means that GSettings is not aware of the settings, because the schema isn't installed. This could happen if

1. You've uninstalled Foliate, in which case you should run it after reinstalling.
2. You're running Foliate without installing, in which case you need to run gsettings with the --schemadir option with the schema directory that you're running Foliate with.
3. You're using Flatpak, in which case you need to either run gsettings inside the app's sandbox, or you can just edit or delete ~/.var/app/com.github.johnfactotum.Foliate/config/glib-2.0/settings/keyfile.

Alternatively, in the first two cases, use dconf-editor, with which you can purge the settings whether the schema exists or not.
