aiongg e81a21e645 refactor(save): delegate atomic writes to craft-atomic
The engine's atomic module keeps its functions and signatures and delegates to craft-libs/craft-atomic (pinned to e9546e19), so every save and export caller is unchanged. write_atomic_with also turns a panicking writer into an error, so its temporary file is removed. Recovery checkpoints and package output keep their own writers, which replace links instead of following them.

On Unix, new files follow the umask and replaced files keep their permissions.

natocool2andClaude Opus 5.5 5a5e97b0a6 Bump quick-xml to 0.41 (RUSTSEC-2026-0194, RUSTSEC-2026-0195)
The .docx/.xlsx text import iterates attributes with quick-xml's default duplicate check, so one crafted
start tag with N attributes cost O(N^2) (RUSTSEC-2026-0194, fixed in quick-xml 0.41). Bumping also clears
RUSTSEC-2026-0195 (NsReader namespace allocation), which this workspace does not reach (no NsReader).

unescape_value() is deprecated in 0.41 (clippy -D warnings); normalized_value(Implicit1_0) is what the
deprecated method now does. Regression test: an element with 100,000 attributes parses in < 5 s.

aiongg 52637295f0 Colour management on craft-cms: Coated FOGRA39 default CMYK, BPC display, FOGRA39 output intent
- designcraft-color: ICC profiles (built-in RGB working spaces, user .icc files) go through
  craft-cms. The default CMYK working space is craft-cms's Coated FOGRA39; CMYK swatches show
  relative colorimetric with the settings' black point compensation, as placed images do.
  Generic CMYK and Device CMYK stay selectable; names of the profiles FOGRA39 stands in for
  resolve to it; ColorSettings::with_known_profiles replaces unavailable saved names with the
  defaults (used when the UI restores saved settings). Lab, gamut error and proofing of ICC
  CMYK spaces use craft-cms transforms. The Generic CMYK output profile is encoded by craft-cms.
- designcraft-images: Profile, Transform, TransformOptions, Intent and Builtin are craft-cms's;
  its black point compensation replaces the module's sRGB table. Untrusted profiles are still
  ignored with a log line.
- designcraft-pdf: the PDF/X output intent is the working CMYK space's profile: the FOGRA39
  built-in with identifier FOGRA39, user profiles as loaded, Generic CMYK otherwise.
- moxcms is no longer a direct dependency.

aiongg b20ddf87ec Images: CMYK and profiled photos show in their colours
Placed rasters are converted to display sRGB once, at decode time, in one
module (designcraft-images colour):
- embedded ICC profiles in JPEG, PNG, TIFF, WebP and PSD (RGB and grey) are
  applied; sRGB-like profiles leave the pixels exactly as decoded
- CMYK JPEGs (incl. YCCK, Adobe-inverted values), CMYK TIFFs and CMYK PSD
  composites go through their embedded CMYK profile, else the working CMYK
  space, with the colour settings' intent and black-point compensation
- oversized (> 16 MiB), unreadable or mismatched profiles are ignored with a
  log line

The render image cache is rebuilt when the colour settings change. PDF/A
exports of CMYK TIFFs get the same managed RGB as the screen.

aiongg 38dad0fbde Windows: dragging across monitors with different scales doesn't grow or crash the window
winit 0.30.13 mishandles WM_DPICHANGED during a live drag on Windows 11:
the window flips between the two scales and grows past the GPU surface
limit. Pin winit to the one commit of rust-windowing/winit#4694, its
0.30.x backport of the fix.

The device asks for the adapter's largest texture side instead of
eframe's fixed 8192, and an uncaptured wgpu error is logged instead of
panicking, so a window larger than the surface limit draws wrongly
until it shrinks rather than closing the app.

Brandon ThomasandClaude Opus 5.5 3624f48819 Release 0.7.1: rebuild with the fixed shared release workflow
The previous release build failed in craft-common-actions, not in this
repo: riscv64 packaging got --formats deb,rpm,tar (fixed in
craft-common-actions#3), Linux jobs lacked the ALSA headers
(craft-common-actions#5), and Windows signing needed the AZURE_* secrets
listed in the caller.

The system font scan also reads the font files CoreText has available
(core-text's collection of all available fonts, safe API), so fonts that
Adobe Fonts, RightFont and other font managers register from their own
folders are cataloged. Files the font folders already hold are read once;
paths that lead to no file are skipped. FontDb::global serves the desktop
app and designcraft-cli alike; the scan stays in the background.

Abdelrehman Fouad 62faa8eee2 Text: Optical kerning spaces pairs from their outlines
Optical kerning was treated exactly like Metrics: the font's kern pairs
and nothing else, so text set with Optical in InDesign came out wider,
rewrapped and went overset in tightly fitted frames.

Now the font's pairs are turned off for Optical text and each pair is
spaced from its outlines (crates/compose/src/optical.rs): every glyph's
ink is sampled into 28 bands across the em, the pair's mean and smallest
ink gap over the bands both glyphs ink are compared with the font's
stem-to-stem gap (the pair nn, or HH then oo), and the pair moves 60% of
the way towards it, keeping 30% of that gap and moving at most -0.12 or
+0.06 em. Latin, Greek and Cyrillic letters, digits and Western
punctuation take part; spaces, marks, missing glyphs, right-to-left
runs, upright and tate-chu-yoko glyphs and pairs across a fallback font
keep their font spacing. Profiles and references are cached, bounded.

Tests: AV, To and r. close up and nn stays; HH closes up under Optical
but not Metrics (fails on main); every change on a pangram stays within
the bounds and spaces keep their width; profile, gap, adjustment and
character-class unit tests.

Docs: typography parity Kerning row and remaining effort, gap 4,
ROADMAP milestone 6 and progress log.

Fixes #181.

aiongg 62df5e764a Merge file-open-os: Save adds .designcraft, and the OS opens DesignCraft and IDML files
- apps/designcraft/Cargo.toml: the macOS target keeps objc2 0.6 / objc2-app-kit 0.3 (IME) and
  adds fmv-macos-events =0.1.0, which uses the same objc2 and objc2-app-kit versions.
- apps/designcraft/src/main.rs: the shared Arc<gpu::Startup>, catch_unwind and restart flow
  stay; the Apple-event handlers are installed before run_native (outside catch_unwind, held
  until the window ends), the app drains the inbox each frame, and documents that arrived are
  noted on the Startup. The open dialog keeps the INDD/INDT filter and ends with All files.
  The open-filter test checks both; the save-dialog test is added.
- apps/designcraft/src/gpu.rs: Startup::opening records the documents the OS handed this run;
  a start again after a graphics failure (both finish and the first-frame watch) passes them
  as file arguments, since Finder doesn't send them twice.
- apps/designcraft/src/apple_events.rs: poll returns the documents it handed the app, and
  queued() returns those still in the inbox when the window ends.
- crates/engine/src/cmd/file.rs: file.open decides by content first (IDML by its mimetype
  entry, then a DesignCraft package or JSON), then an InDesign file by its signature or
  .indd/.indt extension, then a .idml or .designcraft extension for the reader's own error;
  anything else is "not a DesignCraft or IDML file". INDD stays in file.openBytes. Save
  commands add .designcraft as on file-open-os; the params docs describe all of it.
- crates/engine/src/cmd/mod.rs: re-exports from both sides (is_document,
  with_document_extension and layout::chapter_numbering).
2026-10-10 23:21:12 +00:00
aiongg 11532d961e Documents: Save adds .designcraft, and the OS opens DesignCraft and IDML files
- file.save / file.saveAs / file.saveACopy add the .designcraft extension to a
  given path that lacks it and report the path written; saving back to the
  document's own file keeps its name.
- file.open tells DesignCraft and IDML packages apart by content, so files
  without an extension open; anything else is "not a DesignCraft or IDML file".
- Dropped or web-picked files without an extension open as documents when their
  content is one.
- Desktop save dialogs filter on the suggested extension and add it to a name
  typed without it, asking before replacing an existing file; the open dialog
  gains "All files".
- macOS: open-documents Apple events (Finder, Dock, Open With) through
  fmv-macos-events, queued until the window is ready; Info.plist declares the
  .designcraft type and an imported .idml type with CFBundleDocumentTypes.
- Windows MSI: .designcraft ProgId with an Open verb, IDML under Open with.
- Linux: shared-mime-info for both types and MimeType in the .desktop file.

choice, #806, #964) and reconciled with the backend fallback of #297:

- The app picks the window's adapter itself (eframe's native_adapter_selector,
  apps/designcraft/src/gpu.rs): adapters that can't present never, then
  WGPU_ADAPTER_NAME, hardware before software, native backends before OpenGL,
  the GPU that drives the primary display (Windows EnumDisplayDevices through
  winsafe, Linux /sys/class/drm), the power preference (WGPU_POWER_PREF;
  otherwise power saving on Windows and macOS, the system's order elsewhere),
  then DX12 before Vulkan. Every adapter and the choice are logged.
- wgpu's indirect-call validation is off (WGPU_VALIDATION_INDIRECT_CALL=1 turns
  it back on): its compute shader failed to compile on an Intel Mac and lost
  the Metal device (#334, first error).
- run_native runs under catch_unwind. A wgpu error or a panic in wgpu,
  egui-wgpu or naga during the first frames, or a first frame that doesn't
  reach the screen in 20 s, starts the app again without that adapter
  (DESIGNCRAFT_GPU_SKIP; exec on Unix, a new process on Windows). When no
  adapter of the start's backends is left, it starts again with the next
  backend. Each restart leaves out one more adapter or backend, so they end.
  Adapters without PCI ids (Metal) are keyed by name.
- The backend fallback (gpu/backend.rs, gpu.json) stays for driver faults that
  take the process down. Windows tries DirectX 12, then OpenGL, then Vulkan,
  each in its own instance: Vulkan last because creating its instance loads
  every installed Vulkan driver, and OpenGL kept out of the DX12 instance
  because creating it crashed in AMD's atio6axx.dll (#167).
- main returns an ExitCode and logs why the app stopped to standard error and
  the log file, which is all a Windows start without a console leaves (#273).
