Kurze Stichwörter treffen nur noch am Wortanfang bzw. als ganzes Wort ("gen" nicht in
"Leiden", "war" nicht in "Gegenwart"), Ordnernamen werden nicht mehr nach Wörtern
durchsucht, sondern über FOLDER_THEMES einem Motiv zugeordnet. Mehr Varianten für
Philosophie, Psychoanalyse und Krimi; Großbuchstaben und lange Autorennamen laufen
nicht mehr über den Rand.

# Folders and the library (redesign)
|
|
|
|
## Folders everywhere: tags shown as filter chips
|
|
|
|
One idea of a folder for every area — Bücher, Zeitschriften, Hörbücher,
|
|
Podcasts, Blogs (and the news' Ressorts, which already work this way):
|
|
|
|
- A thing can be in **several folders** (they work like tags); none is fine.
|
|
- Folders are **filters**, not rooms: a row of chips on top —
|
|
`Alle · <folder> n · … · Ohne Ordner` — tapping one filters in place; no
|
|
"inside a folder" view, no back button. On a wide window the row wraps.
|
|
- **Assigning**: mark one or more things (long press / ☐ select mode, or ⋮ on
|
|
one), then "In Ordner …": a sheet with every folder of the area as checkboxes
|
|
and "Neuer Ordner". No typing a name that must match.
|
|
- **Managing** (⋮ on the chip row → "Ordner verwalten"): rename, merge (rename
|
|
onto an existing name), delete (the things stay, only the folder goes),
|
|
reorder by dragging. The order is the chip order.
|
|
- **Automatic groups** stay automatic and look different from folders (no
|
|
chip; a stack/group heading): audiobook series, magazine periodicals.
|
|
|
|
### Where folders are kept
|
|
|
|
| Area | Field | Notes |
|
|
|------|-------|-------|
|
|
| E-books, magazines | encrypted meta `folders: [names]` | `folder` (the first) kept for older clients; read `folders` or else `[folder]` |
|
|
| Audiobooks, podcasts | `PodcastFeed.folders` (JSON list) | feed setting `folders`; `folder` (string) still accepted |
|
|
| Blogs | `Source.folders` (exists) | |
|
|
| News | `Source.category` (one Ressort) | already chips in Nachrichten |
|
|
|
|
The folder order per area: e-books in the encrypted user settings blob (names
|
|
are private), the others on the server (`/podcasts/folders/`, `/feeds/folders/`,
|
|
`{order: [names]}`).
|
|
|
|
### Shared code: `static/js/folders.js` (diora-web, every platform)
|
|
|
|
```
|
|
DioraFolders.chips(el, {folders: [{name, count}], active, none: count|0, onPick(name|''|null), onManage()})
|
|
DioraFolders.assign({title, folders: [names], selected: [names], onDone(names)}) // the sheet
|
|
DioraFolders.manage({folders: [names], onRename(old, new), onDelete(name), onOrder(names)})
|
|
```
|
|
Each area keeps its own storage and calls these for the look and the dialogs.
|
|
|
|
## The library (Bücher, Zeitschriften)
|
|
|
|
- **Header**: title, search (title, author), sort (zuletzt gelesen · Titel ·
|
|
Autor · hinzugefügt), ⊞/☰ grid or list, `+` (Buch hinzufügen, Aus Cloud).
|
|
- **Filter chips**: Alle · Angefangen · Ungelesen · Gelesen — then the folders.
|
|
- **Weiterlesen**: one card on top (cover, title, "Seite 132 von 186 · gestern",
|
|
▶), not repeated in the list below.
|
|
- **Grid** (default on phone and desktop): covers with a progress line, title.
|
|
**List** (default on e-ink / diora Reader): one row per book, small cover,
|
|
title, author, % / ✓.
|
|
|
|
### Covers, end-to-end encrypted
|
|
|
|
A client that has a book's file extracts its cover (EPUB: the OPF cover image;
|
|
PDF: page 1), scales it to 240 px wide JPEG, **encrypts it with the user's key**
|
|
(AES-GCM like the meta) and uploads it once: `POST /books/<id>/cover/
|
|
{cover_ct, cover_iv}`. `GET /books/` lists `has_cover`; `GET /books/<id>/cover/`
|
|
returns `{cover_ct, cover_iv}`. Clients cache the decrypted image locally. The
|
|
server never sees a cover.
|
|
|
|
### Generated covers
|
|
|
|
A book without a cover (or one set to `cover: 'generated'` in its meta) gets one
|
|
drawn by `static/js/gencover.js`: an SVG, the same on every device, never stored.
|
|
A **concept** (motif, palettes, typeface) is chosen by score:
|
|
|
|
- words in the title (3), the shelf category (2) and the author (2, only at a
|
|
name's start). A stem of five letters or more counts anywhere (German
|
|
compounds), a shorter one at a word's start, one of three letters as a whole
|
|
word; `^` / `$` in the list force a word's start / end.
|
|
- the folders, by name (`FOLDER_THEMES`): the first counts 2.5 — more than an
|
|
author or shelf word, less than a title word — further ones 1.
|
|
|
|
Concepts: konstruktiv (Marx), geometrie (Philosophie: rings, turning squares,
|
|
triangle/circle/square), psyche (Psychoanalyse: two ellipses, the Borromean
|
|
knot, a spiral), karte (Geschichte), kosmos (Science-Fiction), ornament
|
|
(Fantasy), raster (Politik, Soziologie), schatten (Krimi: a red line, a lit
|
|
doorway), grusel (Horror), klassiker (patterned paper with a title plate),
|
|
sakral (Religion & Mythologie), spiel (Kinder & Jugend), code (Informatik),
|
|
typo, wellen, botanik, berge, zellen — and bauhaus when nothing matches. A hash
|
|
of title and author picks palette, layout and every detail.
