Application Settings Backup

The command-line utility mackup provides a decent starting point to enable Install Doctor to provide the capability of backing up personalized application settings. mackup has a shortcoming though. It was not designed to accompany configurations that end up being stored in different places on different operating systems / package managers.

Mackup

For this reason, we use mackup to handle the back-up and restore of the "golden" copy of application settings which will usually be stored in the ~/.config directory. In some cases, we can get away with, for example, symlinking the ~/.config/ABC to ~/Library/Application Settings/ABC. But, in other cases like Flatpak, we need to keep the Flatpak configuration stored under ~/.var/com.abc.XYZ synchronized with ~/.config/ABC.

software.yml Application Setting Definitions

The mackup configurations will handle the backing up of the "golden" copy and the technical package manager specific linking / synchronization is handled by our CLI. If you browse through the software.yml file, you will see something like the following which provides enough details to our CLI to handle the technical details:

  google-chrome:
    _name: Google Chrome
    _app: Google Chrome.app
    _link:cask:
      - src: "${XDG_CONFIG_HOME:-$HOME/.config}/google-chrome/Default"
        target: "$HOME/Library/Application Support/Google/Chrome/Default"
    _link:choco: 'TODO'
    _link:flatpak:
      - src: "${XDG_CONFIG_HOME:-$HOME/.config}/google-chrome/Default"
        target: "$HOME/.var/app/com.google.Chrome/config/google-chrome/Default"
    cask: google-chrome
    choco: googlechrome
    flatpak: com.google.Chrome
    yay: google-chrome

The keys that start with _link add the instructions necessary to synchronize the configurations amongst the various possible locations in the most efficient manner. The cask and flatpak have their definitions in place. The choco still needs some work. And the yay option needs no definition because the configuration is already in the proper place by default for unrestricted system package managers.

backup-apps Script

On a side note, once the proper application definitions are in place in the software.yml file and the proper configurations are made in this folder's .mackup folder, then you can use our convienience script located at ~/.local/bin/backup-apps to perform the backup. It was created to avoid having to leave a ~/.mackup folder and a ~/.mackup.cfg file in the home directory.

TODO

We need to go through the software.yml file and figure out which applications would benefit from application setting synchronization. Basically, any application that has cask and flatpak options will need to be configured. It is possible that some settings might reside outside of ~/Library/Application Support.

For now, the choco definitions should use Unix style forward slash definitions along with %APPDATA% to define the location of the settings.
