"Duplicate originals" appears under the trash in the collections
sidebar while the catalog holds any, and Settings says how many there
are beside the other whole-library passes. Both open one page: every
group with its picture and paths, the copy that stays (tap another path
to change it), a per-group Include box, what the survivor will gain and
any flag, label or face conflict, and why a group was skipped.
The summary is the dry run -- "N groups, M files to trash, K skipped" --
and nothing moves until "Check" has read the copies and "Move M copies
to trash" is pressed. Both run on workers with progress on the page, in
the activity register and, for the move, on the library status line;
Stop ends a job between groups. When it ends the grid, the sidebar and
the trash are refreshed and the survivors' judgements are written to
their sidecars and XMP the way a rating keystroke writes them.
The page is paginated at 30 groups, so a redraw decodes 30 thumbnails
and previews 30 merges whatever the size of the library. Back and
Escape leave it like its own Back button.
Rating and flagging in develop (FR-UI-5, amended 2026-09-19) landed with
the keyboard audit: 0-5, P, X and U in develop's key scope, stars and
Pick/Reject in its top bar, and flag and stars on the roll's cells. Two
of the amendment's rules were held by nothing. The keys must judge the
photograph on screen and never a selection left behind in the grid, and
judging must not move on to the next frame, which is culling's
auto-advance and not develop's.
The rating, flag and label callbacks that take a row each spelled the
row-to-image lookup themselves. It is now one function, `image_at_row`,
which answers None for a negative row as well as one past the end: the
roll passes -1 when the open photograph is outside the loaded window,
and the right answer then is to judge nothing. A test says so. The key
bindings live in Slint, where no test can press them, so a second test
reads develop's handler as the gestures gate and the canvas-order test
do, and checks that each judgement key calls the row callback on
`library-roll-current` and that none of them steps the roll or the
cursor.
The writes themselves go through `apply_judgement`, the grid's own path:
one catalog statement, then the sidecar and XMP writes behind it.
An audit of every action by view against the keys the handlers bind left
develop without zoom, pan, fit or a way back to the grid, the grid without
select-none, thumbnail size or keywording, People with no key at all, and
the export and copy sheets without Enter. It also found the reverse gap
FR-UI-5 forbids: pick and reject had no route but P, X and U, and the
2026-09-19 amendment's judging in develop had not been built.
Develop: Ctrl+= and Ctrl+Plus zoom in and Ctrl+- out about the middle of the
view, Ctrl+0 fits and Ctrl+1 goes to 1:1, Shift and an arrow pan a magnified
view, G goes back to the grid, Ctrl+Y redoes, and Enter keeps a crop that hid
a mask. 0-5, P, X and U rate and flag the open photograph without moving on,
with stars and Pick/Reject in the top bar as the pointer and touch route.
= and - nudge the control last moved by a hundredth of its travel; the
framing sliders, perspective included, now count as "last moved", so R puts
them back as well. J turns the selected mask part's join chip.
Grid: Ctrl+D and Ctrl+Shift+A clear the selection, = and - resize the
thumbnails, Ctrl+K opens keywording, and Flag in the selection bar gives
pick and reject a pointer and touch route. Sidebar: Enter commits a
collection's name, and Enter or Escape hands the keyboard back to the grid,
where it used to go nowhere until something was clicked. People: Up and Down
walk the rail, F2 puts the name field under the keys, and Escape or Back now
leave the screen the way its back button does instead of doing nothing.
Sheets: Enter does what the export or copy sheet's button does.
The choices follow Lightroom where it has one. No new key steals typing: the
grid's and People's keys live on focus holders that are not ancestors of any
text field, and the sheets' Enter comes after a focused field has had it.
Every binding is tagged beside its handler, and the gate added in the
previous commit holds the two to each other.
Colour labels could be read from a Lightroom sidecar and queried by the
selector, but nothing drew one or set one, so the only labels a library
held were ones another program had written.
Every mark carries its label's initial on its colour — R, Y, G, B, P —
so a label is read without telling red from green, which is what
NFR-A11Y-3 asks of colour labels by name. A grid cell shows the mark
before its filename. In the grid, 6, 7, 8 and 9 set red, yellow, green and
blue as Lightroom's keys do, on the photograph under the pointer or on
the selection by the rule the star keys follow; the same key again takes
the label off, and over a mixed selection it sets it on all. The
selection bar gains Label, which opens the six choices — each a mark and
a name — and purple, which has no key, is there. In develop the top bar
says "Label: Green" beside the mark, opens the same choices, and 6-9
label the open photograph.
Each gesture is one catalog transaction, then the grid, the counts and
both sidecars are written as a rating's are. The filter bar gains a chip
per label, its mark and its name with a count, one at a time; the filter
is one SQL term, travels in the place record, and "All" clears it.
A rating and a flag are written to DarkRoom's sidecar as well as the
catalog, because the catalog is a disposable index and the sidecar is
how a judgement reaches the photographer's other devices. A label had no
place there, so once labels could be set, one would have lived only in
the catalog of the device it was set on and gone with it.
The sidecar version now carries `label` (0 none, 1-5 as the catalog
codes it), written only when set. It merges under the rating's rule, so a
device that never labelled a frame cannot clear another device's label,
and a code this build does not know reads as none rather than as some
other colour. A judgement write carries the catalog's label with the
stars, and the scan takes a sidecar's label into the catalog when it has
one. An older build keeps the line as an unknown key and writes it back.
bddf325 and 00c028c went in unformatted, so the Desktop job's
`cargo fmt --check` step failed on master (run 1693) and the release job
that needs it was skipped. Whitespace only.
Rating keys in the grid follow darktable's rule: with the pointer over a
photograph outside the selection, 0-5, P, X and U judge that photograph
alone; over one inside it, the whole selection, as before; off the grid,
the selection. The hover is cleared when the grid scrolls, so a key after
a wheel turn cannot judge whatever used to be under the pointer.
Holding F and tapping digits filters by stars: one digit for exactly
that many, two for everything between them, F alone to show every
rating again. The filter gains a ceiling to do it (`max_rating`, one
BETWEEN in the query). The place record carries it, and a record from an
older build reads as having none. The star chips light across a capped
range and the bar says "2-3★ only" beside them.
The grid also takes Ctrl+E and Ctrl+Shift+E for the selection, Ctrl+V to
paste onto it and Ctrl+A to select all. The "Gestures" button is now
"Help", its sheet "Controls and shortcuts", and F1 opens it.
The scan/opening/status/error lines, offline mode and its retry, pinning a
collection offline, the sync and thumbnail-sweep state, and the callbacks
that route the grid to a rescan, a sync, another library, a panorama merge
or an export — the last of what AppWindow still carried under the
library- prefix — move onto the `Library` global started earlier on this
branch. Rust reaches them through window.global::<Library>() rather than
window.set_/get_/on_/invoke_ on the root.
library-visible is the one name that stays: it is computed from
active-page and active-view, the shell's own routing state, which a
global cannot read. AppWindow now declares no other library- property or
callback.
The keywording sheet's rows and its open/assign/unassign callbacks, the
star and flag callbacks a cell click or a judgement key fires, the burst
toggle and representative-chosen callbacks, the trash-selection shortcut,
and the rating/unjudged/flag filter chips with their rating-counts model
move from AppWindow onto the `Library` global started in the previous
commit. Rust reaches them through window.global::<Library>() rather than
window.set_/get_/on_ on the root.
AppWindow carried the grid's loaded window of cells, the keyboard cursor,
drag and drop, the held-row long-press state, columns and cell size, the
scroll and viewport bookkeeping, the photo roll's pick and centre-request,
and the local-only/reorder/collection-filing gestures that act on a
selection, as properties and callbacks on the root component. That state now
lives in the `Library` global declared in library.slint, next to the structs
(LibraryCell, TimelineBar, KeywordRow, PersonChip) it and the grid's other
components already share; Rust reaches it through
window.global::<Library>() instead of window.set_/get_/on_/invoke_ on the
root, the same change collections.slint's `Collections` global made for the
sidebar.
library-visible stays on AppWindow: it is computed from active-page and
active-view, the shell's own routing state, which a global cannot read.
Everything else still prefixed library- — the timeline, the filter bar,
ratings and flags, keywording, and the routes and status lines — stays on
the window for now and moves in the commits that follow.
controller holds LibraryController and the window-sizing constants every
other module reads and writes through pub(super) fields, the same shape
collections_ui and develop already use. open is the launch-to-scan cycle and
the worker that checks the catalog file before either touches it. offline is
what of a collection is on this device and the prompt that offers to change
it. window fills the grid model from the catalog and drains the thumbnail
fetch, which is the piece the catalog-reads-are-proportional-to-what-changed
rule (docs/catalog.md §1) bears on most directly. sync is the background
passes that reach beyond the loaded window: the metadata sweep, the
whole-library thumbnail pass, and the exchange with the server.
ratings_keywords applies a judgement or a keyword to a selection and queues
the sidecar and XMP writes behind it. timeline is the capture-time sidebar
and the photographer's place together, kept in one file because a restored
place ends by moving the timeline marker and a scrub is a restore of one
instant, so most calls between the two would otherwise cross a module
boundary. grid wires the grid's own callbacks — the keyboard cursor,
cell-size zoom, the routes into and out of develop — and filter_bar wires
the rating, people, date and offline-scope filters, calling back into
whichever of the above owns the work a filter change triggers.
Extracted by item rather than by line range, so every doc comment and
TRACES/GESTURE annotation stayed attached to the code it describes; the
sorted set of TRACES/GESTURE lines in the new directory is identical to the
original file's. Tests moved with the code they exercise, including the
handful of fixtures — settle, model_of, with_catalog, zoom_cell, pinch_step
— that only one target module needed and so were not worth sharing through
a test_support module the way the other splits use one. Items that crossed
a new module boundary were widened from private to pub(super), narrower
than the whole-file access the original gave them; a few items already
pub(crate) for recovery_ui or presets stayed there rather than being
narrowed, since nothing needed them tightened further.
mod.rs re-exports the same surface library_ui:: callers used before, so
lib.rs and every other caller needed no change.
