halkyon/apps/todo/snap/snapcraft.yaml

# Halkyon Todo's Linux app as a Snap (ADR 0033, step 5), built in LXD by the release
# tool (`dart run tool/release.dart todo`): snapcraft builds one recipe a folder, from
# its snap/snapcraft.yaml, and the root's snap/ is Learn's, so the tool builds this one
# in a clone of the repository at the release's tag with this folder in place of the
# clone's snap/ (`SnapRelease.projectPath`), but for snap/local/, which the recipes
# share. By hand, the same: in such a clone, `snapcraft pack`.
#
# It builds what is committed (the source is the clone's HEAD, the tag), never a
# working tree with its build caches, and always for todo.halkyon.eu. Flutter is
# pinned like the local and CI one (FLUTTER_VERSION in .forgejo/workflows/ci.yaml),
# spelled out as in Learn's recipe, which says why.

summary: Tasks and projects, sealed and synced between your devices
description: |
  Halkyon Todo keeps your tasks: an Inbox for what comes up, projects with
  sections, sub-tasks and labels, Today with what is overdue, and Upcoming as
  an agenda that opens into the month. Tasks repeat (every day, every other
  Tuesday, the first Monday of each month), have reminders, deadlines and
  priorities, and are typed the quick way: "Call Anna tomorrow 9am #Home p1".

  Each project shows as a list, a board or a calendar, grouped, sorted and
  filtered as you set it, the same on every device. Tasks are dragged between
  sections, days and hours.

  Everything is sealed on your device with your account's keys before it
  reaches the instance, which can't read it. You sign in with SimpleLogin, by
  Proton, or with an email address, a password and an authenticator app. It
  connects to todo.halkyon.eu, the project's instance, or to any other:
  everything an instance needs is in the repository, to run your own. The app
  is AGPL-3.0 and the server SSPL-1.0, so all of its code is public.
