Updater Scripts / Tooling

[zikeji]

With my other discussion I share my own installer/updater, however it is very much a separate layer that utilizes AppManager. It would be nice to integrate into the built in update mechanism.

Before I work on anything I would like to spitball a spec/proposal:

In AppManager we can alternatively supply a path to a executable - not sure how this would look in the UI, maybe just lets you paste the path directly into the Update Link.

Executables being passed here would be expected to support two subcommands (latest, download) that AppManager would leverage.

Workflow:

1. AppManager would call the/updater/executable latest and compare stdout against the current version
2. If same, no updates
3. Otherwise, then call the/updater/executable download and use stdout as a valid path to an AppImage
4. Run the internal install mechanism against the output of Zsync update feature #3.

A very rough draft of how this would be expected to function and documented. But this would offer alot of flexibility for specific needs when you have closed source AppImages.
