2026-07-13fullscreen: info/EXIF, fullscreen, slideshow, Esc back (ot0)Paul Buetow
M4 (task ot0): fullscreen + slideshow + info overlay. - src/info.{c,h}: plain-C EXIF gather via libexif (camera, lens, focal, aperture, shutter, ISO, datetime, orientation) + file info (dims, format, size). info_format() produces the overlay text. Unit-tested. - src/window.c: fullscreen toggle (f), slideshow (S, 3s auto-advance), info overlay (i, GtkLabel in GtkOverlay, auto-hide 5s), Esc contextual back (fullscreen→unfullscreen→large→grid→quit). Stack wrapped in GtkOverlay. ggaze_window_get_stack() accessor for tests. - src/shortcuts.c: f, S, i, Escape bindings. - meson.build: libexif dep added. - tests: unit test_info (EXIF extraction + orientation tag). 14/14 green, ASan clean.
2026-07-12walkdir: navigator, shortcuts, window wiring, drop target, tests (ht0)Paul Buetow
M2 (task ht0): walk the directory. - src/navigator.{c,h}: GObject (no GtkWidget) holding the folder listing — image-MIME filter + extension fallback, hide-RAW-sidecars (decision #33), sort name/time/size, cursor + prev/next/wrap, path-based marks (survive re-sort, pruned on rescan/monitor, cleared on remove), nearest-fallback, GFileMonitor debounced 250ms (decision #28), 'changed' signal. 92% gcov. - src/shortcuts.{c,h}: GtkShortcutController (MANAGED) binding h/l/Left/Right/ g/G/o/q to win.* actions; one table all milestones add to. - src/window.{c,h}: open file->parent+current / folder->first; h/l/g/G actions -> nav -> load -> viewer; single GCancellable last-write-wins (g_file_equal guard for M3 async); header title 'filename · n/total'; GtkDropTarget (GDK_TYPE_FILE_LIST, many->first, decision Z); GtkFileDialog open. - data/gschema: add hide-raw-sidecars key. - tests: unit test_navigator (12 subtests), integration test_walk_folder (temp fixtures walk + ./sample-images skip-if-absent). 8/8 green; ASan clean (GIO_USE_VFS=local in fixtures_env). Fixed during this milestone: a UAF (borrowed c_name used after unref), a cancellable double-ref leak, time::modified UINT64 vs INT64, and several test-harness leaks. Sub-agent review issues addressed (mark pruning on rescan/monitor, remove-before-cursor test, recursive temp-dir cleanup, callback _cb naming, connect-before-mutate).
2026-07-12showimage: loader, detect, viewer widget, EXIF orientation, tests (gt0)Paul Buetow
M1 (task gt0): show one image with zoom/pan. - src/loader/detect.{c,h}: magic-byte format sniffing (JPEG/PNG/GIF/WebP/ TIFF/ICO/JXL/AVIF/HEIF) -> GgazeFormat; pure, no I/O, unit-testable. - src/loader/loader.{c,h}: loader_load() sniffs the header and dispatches to the first registered backend; GgazeLoaderBackend struct; pixbuf is the fallback (last, accepts UNKNOWN). M1 ships only the pixbuf backend. - src/loader/backends/pixbuf.c: GdkPixbufLoader decode + gdk_pixbuf_apply_embedded_orientation (decision #26) -> GdkTexture via gdk_memory_texture_new (avoids the deprecated gdk_texture_new_for_pixbuf). - src/viewer.{c,h}: GgazeViewer : GtkWidget custom widget (decision #31) — fit/100%/in/out zoom, cursor-centered zoom, drag-to-pan with clamping, dark background, GtkSnapshot render nodes. - src/window.c: open -> loader_load -> viewer_set_texture -> stack 'large'. - tests: unit test_detect (13 cases) + test_loader_pixbuf (plain/rotated-EXIF 8x4 orient6->4x8/png/rgba/missing/unsupported jxl-avif-heif/corrupt), integration test_open_and_show (fixture + rotated + ./sample-images skip-if-absent). 6/6 green; detect 97% / loader 91% / pixbuf 87% coverage. - fixtures: gen.py produces plain.jpg, rot6.jpg, small.png, rgba.png. - AGENTS.md: documents the ./sample-images optional test corpus convention. Sub-agent review fixes: use-after-free of c_name in ggaze_window_open (BLOCKER), gtk_stack_get_pages leak in test_window (BLOCKER), coverage gap, dead branch, viewer measure, _prefix/_cb naming, include order, extern in header, pan clamp, stale comments — all addressed.
2026-07-12skeleton: GtkApplication, window, GSettings schema, desktop, tests (ft0)Paul Buetow
M0 (task ft0): the app shell — no feature views yet (those are M1 large, M7 grid). - src/main.c: g_application_run + --version via handle-local-options (--help is GApplication's own); exits before activate so --version works headless. - src/app.{c,h}: GgazeApp : AdwApplication : GtkApplication (libadwaita styling, decision #29), single-instance (decision #32), G_APPLICATION_HANDLES_OPEN; activate + open reuse the active window (replace-on-new-open); ggaze_window_open remembers the GFile. - src/window.{c,h}: GgazeWindow : GtkApplicationWindow with AdwHeaderBar and a GtkStack (children 'grid'/'large', default 'grid'); dispose clears the file. - data/org.buetow.ggaze.desktop (image/* MIME, validated) and data/org.buetow.ggaze.gschema.xml (all keys + defaults, --strict clean). - meson: libggaze static lib shared by the executable and tests; install to bindir/applications/glib-2.0 schemas; gnome.post_install compiles schemas + updates desktop db. - tests: unit test_app (--version/--help/unknown via subprocess), integration test_window (offscreen stack checks + open-titles), bootstrap. 3/3 green. - docs/tech-stack.md: window-geometry shape corrected to (width,height, fullscreen,maximized) to match the schema.
