halkyon_app: data locations as precise as a country or a state
An operator's DATA_LOCATION and BACKUP_LOCATION may name a subdivision
(ISO 3166-2, US-CA, DE-BY) besides the EU or a country. The app adds
"(EU)" to a member country and the country to a subdivision ("Germany
(EU)", "California, United States", "Bavaria, Germany (EU)"), in
English and German, and shows the most specific flag there is: a
subdivision's own where the flag package has one, else its country's.
Subdivision names come from Unicode CLDR 48.2 (tool/subdivision_names.py),
bundled with their licence, which the app registers.

halkyon_shared

Shared Dart packages across Halkyon apps, a pub workspace:

  • halkyon_ui: Halkyon's look, the theme, fonts, layout and shared widgets (Flutter).
  • halkyon_app: what every app is built around, on an instance's halkyon_base: the instances a device keeps accounts on, signing in, each person's data opened and closed, and syncing it (Flutter).
  • halkyon_base: what every Halkyon server has, as a Serverpod module (halkyon_base_server and its generated client halkyon_base_client): signing in, the account and its deletion, the pruning, and the instance's basics.
  • halkyon_core: low-level primitives (pure Dart), SerialQueue and CoalescingRunner among them.
  • halkyon_interop: cross-app contracts (pure Dart).

Dart 3.13 and Flutter 3.47, with LeanCode's lints (leancode_lint), configured once in analysis_options.yaml here, which every package includes but the generated halkyon_base_client: its analyzer plugin only reaches packages of a workspace from the root. Run flutter pub get and dart analyze --fatal-infos here, and each package's tests in its folder (dart test, or flutter test for halkyon_ui, its example and halkyon_app). halkyon_base_server's tests start Serverpod's embedded PostgreSQL by themselves and need a git-ignored config/passwords.yaml (see its README).

tool/subdivision_names.py writes halkyon_app's names of subdivisions from a release of Unicode CLDR (python3 -I tool/subdivision_names.py release-48-2).

Licences: the server package halkyon_base_server is under the Server Side Public License 1.0, as the Halkyon servers are; every other package under the GNU Affero General Public License 3.0 or later.

Apps take a package by git, pinned to a signed commit; see halkyon_ui's README.
