feat: an F-Droid repository at learn.halkyon.app
Releases also publish the APK in the project's own F-Droid repository,
https://learn.halkyon.app/fdroid/repo. tool/fdroid_repo.sh adds the APK,
signs the indexes with the repository's own key and uploads them to
ramiel as the user fdroid, whose key can only write into the folder
Caddy serves (rrsync), the APKs first and the indexes last.
tool/release.sh checks that key and its password before building and
publishes after the Forgejo release.
- tool/release/fdroid/ holds the repository's settings (Halkyon, the
snap's icon) and the app's listing (the snap's text), with the
anti-features TetheredNet (learn.halkyon.eu only, for now) and
NonFreeNet (YouTube, the server's SSPL) declared with their reasons,
in F-Droid's own definitions and with its icons (fdroiddata, AGPL v3).
- The index key's certificate is pinned: a new key would make the F-Droid
app refuse the repository.
- fdroidserver v2.4.5, since Ubuntu's v2.2.1 knows neither TetheredNet
nor reasons.

build: Melos, a Dart check and every path for the single repository
- Melos 8.9 as the root's dev dependency, with scripts across the
workspace (analyze, test:dart, test:flutter, generate, check) and its
filters (--diff, --include-dependents); cli_util overridden to 0.5.2
for it, since Learn's flutter_launcher_icons asks for 0.4 and uses only
its logger, unchanged in 0.5.
- tool/check.dart in place of tool/check.sh: packages, formatting of our
own files, analysis, the tools' tests, then every package's tests
through Melos (--changed-since=<commit> for only what changed and what
depends on it). tool/pre-push is the hook: the signature check, then
the checks. CI generates every server's code and runs the same check.
- The images build from the root with a workspace narrowed to what they
need (tool/workspace_only.sh); compose, the deploy's migration test,
the snap, the release script, the editor's launch files and Learn's
asset tools (run from apps/learn) follow the new layout.
- The project's source is named as project-halkyon/halkyon (source link,
snap, F-Droid listing, release uploads); the AGPL packages carry the
licence's own text.

Halkyon Learn is a spaced-repetition app for your own material: studysets of
|
|
|
|
|
flashcards, notes, learning paths and PDFs, reviewed on an FSRS schedule. Every
|
|
|

|
studyset is made by its learners: build yours for any subject, or copy one that
|
|
|
|
|
someone published. It works offline and syncs between your devices.

Learn from what you watch: play films and shows from your Jellyfin server,
|
|
|
|
|
and every subtitle line is split into dictionary words, with readings above
|
|
|
|
|
and the translation below. Tap a word, and it is a flashcard.
|
|
|
|
|
|
|
|
|
|
Dictionaries for Japanese, Chinese, Korean, German, Greek and English; kanji,
|
|
|
|
|
hanzi and Hangul written by hand, each stroke checked; exam plans for the
|
|
|
|
|
JLPT, HSK and Korean levels, with a daily pace to your exam's date; and
|
|
|
|
|
studysets published to Explore and copied, later releases coming in as
|
|
|
|
|
merges that keep your own edits.
|

|

It starts with an anonymous account; signing in with GitHub or an email
|
|
|
|
|
address later keeps everything. It connects to learn.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.
