TIP: How to remove app configs after uninstalling package

A script/alias I use when removing an app I was only testing.

Updated the “rnsu” function.

Now it is more robust using a fuzzy search, while also checking the .cache and .local/share directories for both folders and files matching part of the package name. Be careful with this and pay attention to which folders/files are being sent to the trash. In any case, you can just restore the files as they are not permanently deleted.
function rnsu
    if test (count $argv) -eq 0
        echo "Usage: rnsu package_name"
        return 1
    end

    set package_name $argv[1]

    # Run the pacman command
    sudo pacman -Rnsu $package_name

    # Ask the user if they want to remove the related files
    read -P "Would you like to remove the related configs for \"$package_name\"? (y/n): " response

    if test "$response" = "y"
        set directories ~/.config ~/.cache ~/.local/share
        set found_items 0

        for dir in $directories
            set -l matches (find $dir -maxdepth 2 -iname "*$package_name*")
            if test (count $matches) -gt 0
                set found_items 1
                for match in $matches
                    echo "Found: $match"
                end
            end
        end
