README

eos-knowledge-downloader

The eos-knowledge-downloader tool is a command line utility which readies a directory of shard content and static files for use in a EndlessOS knowledge application. This tool assumes the app will be packaged as a flatpak, and searchable through EndlessOS's global desktop search.

The cli tool will set up things like a gnome-shell provider and a dbus service file which all knowledge apps should have. It downloads and properly constructs and subscriptions directory of sharded content. Finally, it downloads any application specific assets to a directory, making it easy to set up electron “templates” for use with many different sets of content.

The tools operates by reading in a single app json file which describes all the application metadata needed. This json file can be either local or a url. Similarly, all assets referred to by the app json can be either relative to the app jsons location, or downloaded through and external url. This should make it very flexible where content is stored. Application content can be stored separately from application code if so desired, and the asset content can be stored separately shard content.

For example, you could store app code on github, assets on dropbox and shard content on Endless's content portal. Or you could store assets and code together on github, and custom shard content on google drive.
