Uninstallation always removes settings

[KizzyCode]

The current uninstallation always removes the settings which breaks the "uninstall old version/reinstall new version" workflow performed by Homebrew's Cask (see here or here).

Is it possible to implement a switch like -uninstall_keep_prefs to allow an uninstallation without purging the settings (like apt-get purge vs. apt-get remove)?

[objective-see]

The installer, will perform a 'partial' uninstall if it detects that LuLu is already installed - leaving the settings intact. (i.e. its an upgrade).

But yah, invoking uninstall, will, well uninstall everything!

Ideally the homebrew cask could be updated to just call install :)

Yeah, we discussed this and I don’t see it coming that this will change (the update-process is hard-coded as uninstall-install-step in Homebrew itself)...
In my opinion you’re right because an uninstall-install-step is a reinstallation which is sth. different than an upgrade. However if the auto-updates are fixed (#91), the formula could be marked as auto-updating which would circumvent this problem.
