Animelon's way of learning from video, from the person's own Jellyfin
server: connected per device (Settings, or a studyset's Add material ›
Watch from Jellyfin) with a name and password or a Quick Connect code,
over HTTPS only (plain HTTP only to a server on the same machine); the
token stays in the system's keyring. Shows, films and videos tied to a
studyset follow the person in their settings as the server's and the
item's ids alone (settings schema 9), named by the server when shown.
The Watch screen plays the video (video_player on Android, media_kit's
libmpv on Linux and Windows) with the line in the studyset's front
language cut into the dictionary's words with furigana, and the back
language's line beneath; a word tapped pauses the video and becomes a
card with the line and its translation as its first hint, tagged with
the show. The video's words are listed, most frequent first. The sound is
the track in the studyset's language, whichever the file marks default,
and the menu switches it; the subtitles read are a whole track, never a
forced one (which only covers what the sound doesn't say), and captions
for the hard of hearing only without plain ones. The line and its
translation take the video's width in a box of a fixed height, so the
video keeps its size; in the dark theme the video's colours glow around
it, as YouTube's ambient mode, and the words' panel takes the colour of
the episode's picture under the pointer.
A line is cut into words with one request: DictionaryEndpoint.withKeys
looks up every stretch of it that may be a word, as it stands and as
every word it may be a conjugation of, in the new dictionary_key table
(one row per key, indexed; migration dictionary-keys adds the table and
its index, nothing else), which the loader fills beside the entries.
The instance gets the text of each line looked up and keeps none of it,
as the Watch screen says.
Linux builds need libmpv-dev, and the app links libmpv: the snap stages
Ubuntu's libmpv2, makes the update-alternatives links for BLAS and LAPACK
that ffmpeg's speech recognition needs (staging never runs install
scripts), and removes what the GNOME runtime and core24 already hold, as
older copies of cairo, pango and librsvg hid the runtime's from its GTK.

Halkyon's website is one site for all its apps, as Proton's is, so
Halkyon Learn's page is halkyon.app/learn rather than a site of its own
at learn.halkyon.app, which redirects there. The snap's and the F-Droid
repository's listings point to it.

The launcher showed Flutter's logo: the project template's icons were
never replaced. tool/app_icons.py now makes every icon from the
kingfisher (assets/icon/halkyon_icon.png), through flutter_launcher_icons
v0.14.4 configured in the app's pubspec: Android's adaptive icon (the
kingfisher inset 16 % on white, for each launcher to cut to its shape)
and the square one before Android 8; iOS's, without transparency;
macOS's, the rounded tile on Apple's grid (824 of 1024 pixels); and
Windows', the rounded tile, its .ico with every size from 16 to 256
pixels (the tool writes only 256). It keeps the iOS project file as it
was, which the tool would break (flutter_launcher_icons issue 634), and
writes the snap's icon as tool/snap_icon.py did, which it replaces.
The Linux runner gives its window the bundled icon too, for desktops
that don't take it from the desktop file.

snap/snapcraft.yaml builds the Linux app as a strictly confined Snap on
core24 with the GNOME extension (GTK, WebKitGTK, GStreamer and libsecret
come from its runtime; files and the browser go through the desktop's
portals), connecting to learn.halkyon.eu, the project's instance. It
builds what is committed, with Flutter pinned as in CI.
- The session: libsecret's keyring over D-Bus needs the
password-manager-service plug, which the Store never connects by
itself, so unless it is connected the app keeps the session in an
encrypted file whose key comes from the Secret portal
(snap/local/secret-backend).
- network-manager-observe lets Serverpod hear that the network went and
end the sync's connection at once; until the Store grants it, it too
is connected by hand.
- The listing points to the project, not the instance: the website
learn.halkyon.app, contact and issues support@halkyon.app.
- The icon is the app's with rounded corners (tool/snap_icon.py), for
the Store and the dock alike.
- The app's version is 0.1.0, build 1.
