feat(publish): a release keeps its colour, and a description for Explore
Publishing takes a description for Explore (rich text, as its JSON),
which Explore shows in place of the studyset's own: a studyset may
introduce itself to strangers otherwise than in the library, where its
author may leave it empty. Without one, as from older apps, the
studyset's description as before; one that isn't rich text, or over
100,000 characters, counts as none. A release also keeps the studyset's
colour, which Explore gives out with it; releases before have none. The
publication's releases say their description, for the next publish to
start from.

Migration release-colour adds a nullable column:
ALTER TABLE "studyset_release" ADD COLUMN "colorName" text;
the server before it reads and writes the table as ever.

halkyon_learn_server

This is the starting point for your Serverpod server.

Start your server by running:

cd halkyon_learn
serverpod start

When you are finished, you can shut down the running server with Q.

Dictionaries

The dictionaries people look words up in (JMdict, …) are reference data the server holds for everyone. They come as dictionary files, which halkyon_learn_curator makes from the sources' downloads (its README says how). At every start, and every hour at seven past, the server loads the files in its dictionaries folder that changed since they were last loaded (by their SHA-256): in the background, a source at a time, and all at once, so searches meanwhile still find the old entries. A file it can't read is logged and left out. A dictionary whose file is gone is unloaded, once every file in the folder could be read (the curator removes the files of languages an instance no longer keeps). DICTIONARIES_DIR names another folder.

EDRDG's licence asks a server showing its dictionaries to update them at least once a month:

  • An instance keeps them current by itself: the dictionaries service in deploy/compose.yaml (the curator, in a container of its own) downloads EDRDG's files of the day once its files are a week old, converts them, and replaces them in a volume the server reads (curate update, the curator's README); the server takes them up within the hour. To supply files yourself instead, remove the service and mount deploy/dictionaries/ into the server (compose.yaml says how), and update them monthly.
  • Development: dart run halkyon_learn_curator:curate update --into ../halkyon_learn_server/dictionaries in the curator's folder (about a minute); the server takes them up within the hour.

JMdict in English, with the JLPT levels and Tatoeba's example sentences, is about 20 MB gzipped and takes the server half a minute to load (219,000 entries). KANJIDIC2 in English, with the JLPT levels of the kanji and the kana, is a dictionary of characters beside it (kanjidic-en.jsonl.gz, 0.7 MB, 12,800 entries): the app's Kanji & kana tab. Their licences (CC BY-SA 4.0; CC BY 2.0 FR for the sentences; CC BY for the JLPT lists) ask for attribution: the app lists the credits each file carries.
