🧹 Nitpick comments (3)
faststack/faststack/qml/Components.qml (1)
13-14: Consider usinganchors.fill: parentfor more idiomatic QML.While the explicit
widthandheightbindings are functionally equivalent,anchors.fill: parentis the standard QML pattern for this use case and is more concise.Apply this diff if you prefer the standard approach:
- width: parent.width - height: parent.height + anchors.fill: parentfaststack/faststack/app.py (1)
236-238: Selection cleared even on launch failure.The
selected_rawsset is cleared unconditionally, even iflaunch_helicon_focusfails. Consider moving the clear operation inside theif successblock so users don't lose their selection when launch fails.Apply this diff:
success, tmp_path = launch_helicon_focus(unique_raw_files) if success and tmp_path: # Schedule delayed deletion of the temporary file QTimer.singleShot(5000, lambda: self._delete_temp_file(tmp_path)) + # Clear selection after successful launch + self.selected_raws.clear() - # Clear selection after launching - self.selected_raws.clear() self.sync_ui_state()faststack/faststack/qml/Main.qml (1)
17-27: Theme toggle works but could be more robust.The string comparison of
currentBackgroundColorwith"#212121"works for this simple case but is fragile. Consider using a booleanisDarkThemeproperty for more reliable theme tracking.Example alternative approach:
property bool isDarkTheme: true property color currentBackgroundColor: isDarkTheme ? "#212121" : "white" property color currentTextColor: isDarkTheme ? "white" : "black" function toggleTheme() { isDarkTheme = !isDarkTheme }

🔇 Additional comments (31)
.gitignore (1)
1-1: Good housekeeping improvements to.gitignore.Both changes are beneficial: removing the non-ASCII BOM character (line 1) improves file hygiene and prevents potential tool compatibility issues, and adding
prompt.md(line 25) prevents accidental commits of generated artifacts.Also applies to: 25-25
faststack/faststack/io/watcher.py (1)
5-5: LGTM!The
Optionalimport is correctly used for theself.observertype hint on line 28, accurately reflecting that the attribute can be either anObserverinstance orNonethroughout its lifecycle.faststack/pyproject.toml (2)
8-8: LGTM! Version bump aligns with the release.The version increment from "0.1.0" to "0.2" is consistent with the PR title and reflects the working Helicon Focus integration and viewer improvements.
10-10: LGTM! Author metadata updated.The author change from Gemini to Alan Rockefeller properly reflects the project's ownership.
faststack/faststack/models.py (1)
19-19: LGTM! Well-designed optional field.The
stack_idfield properly supports the new stack association feature with an appropriate optional type and default value, maintaining backward compatibility.faststack/faststack/tests/test_sidecar.py (2)
9-9: LGTM! Import path updated correctly.The import change reflects the relocation of
EntryMetadatafromfaststack.typestofaststack.models, consistent with the model consolidation.
24-24: LGTM! Test expectation updated for new default version.The version assertion correctly reflects the updated default sidecar version (2), maintaining test accuracy.
faststack/faststack/imaging/prefetch.py (2)
26-28: LGTM! Smart optimization to avoid unnecessary work.The equality check prevents canceling and restarting prefetch tasks when the image list hasn't actually changed, reducing churn.
65-80: LGTM! Effective race condition mitigation.The generation capture and dual-check pattern properly guards against race conditions:
- Line 67 detects if a task is stale before starting work (generation changed between submission and execution)
- Line 78 detects if generation changed during the decode operation, preventing stale results from being cached
While
self.generationis accessed without locks, this best-effort approach is appropriate for prefetch optimization.faststack/faststack/ui/keystrokes.py (1)
30-32: LGTM! Key bindings align with new workflow.The changes properly implement the new selection-based workflow:
Snow toggles selection (line 30), consistent withAppController.toggle_selection- Both
EnterandReturnlaunch Helicon Focus (lines 31-32), which is standard practice for keyboard compatibilityfaststack/faststack/io/helicon.py (1)
23-31: LGTM! Robust input validation added.The validation improvements properly guard against configuration issues:
- Lines 23-25: Checks for empty or non-string executable path
- Lines 27-28: Correctly creates a
Pathobject before callingis_file()(strings don't have this method)- Appropriate error logging for debugging
faststack/faststack/ui/provider.py (2)
95-104: LGTM! Clear and informative stack summary.The
get_stack_summaryproperty provides well-formatted stack information for UI display, with appropriate handling of the no-stacks case.
119-125: LGTM! Clean slot implementations.The new slots (
launch_heliconandclear_all_stacks) properly delegate to the controller, maintaining clean separation between UI and business logic.faststack/faststack/qml/Components.qml (1)
15-15: Good defensive check for image count.The addition of
uiState.imageCount > 0prevents potential issues when accessingcurrentImageSourcewith no images loaded. This aligns well with the Python-side handling of empty image lists.faststack/faststack/app.py (9)
10-10: LGTM!Import of
concurrent.futuresis appropriate for handling prefetch task futures and cancellation.
59-59: LGTM!The
selected_rawsattribute properly initializes a set to track user-selected RAW files for batch operations.
63-65: Good fix for proper event handling.Now correctly respects the return value from
handle_key_pressand returnsTrueto Qt when the event is handled, preventing further propagation. This follows the proper Qt event filter pattern.
71-74: Good defensive bounds checking.The clamping logic ensures
current_indexstays within valid range even if the sidecar'slast_indexis stale (e.g., files deleted since last run). This prevents index out of bounds errors.
88-90: Good defensive check for empty image list.Prevents attempting to decode when no images are loaded, returning
Nonesafely.
100-112: Proper handling of cancellation, with acknowledged limitation.The
CancelledErrorhandling prevents crashes when prefetch tasks are cancelled. The comment correctly notes that returningNoneis a simplified fallback. For a more robust solution, consider implementing a direct synchronous decode method as the comment suggests, but the current approach is safe and acceptable.
121-122: Helpful debug logging for UI state synchronization.These debug logs will aid in troubleshooting UI state issues without cluttering production logs.
143-143: Appropriate debug logging for edge case.The debug log when
image_filesis empty helps trace this condition without cluttering normal logs.
192-209: Well-implemented selection toggle with proper guards.The method correctly checks for empty image lists and RAW pair existence before toggling selection state. The UI sync ensures the interface reflects the change.
faststack/faststack/qml/Main.qml (8)
7-9: LGTM!Fullscreen configuration with Screen dimensions is appropriate for an image viewer application.
43-54: Good footer layout improvements.The explicit IDs and anchoring make the layout more maintainable and explicit. The padding calculation is appropriate.
56-70: Good footer label updates with proper theming.The template literals and conditional color bindings correctly display metadata with appropriate visual feedback. The fallback values ensure graceful display when data is unavailable.
72-85: Stack info display is clear with good contrast.The orange background with black bold text provides excellent visibility for stack information. The conditional coloring is well-implemented.
108-129: Well-structured menus with proper action bindings.The new View and Actions menus provide good UI access to features. All action triggers correctly invoke the appropriate methods.
133-133: More descriptive menu text.Changing from "About" to "Key Bindings" accurately describes the dialog content, improving user experience.
141-173: Key Bindings dialog properly themed and updated.The dialog correctly adopts the application theme with appropriate background and text colors. The increased height and updated content improve usability.
175-193: The code is correctly implemented; no changes needed.Verification confirms
get_stack_summaryis properly decorated with@Property(str, notify=metadataChanged)on line 95 of provider.py, anduiStateis correctly exposed to QML viasetContextProperty. The usage in Main.qml line 188 (text: uiState.get_stack_summary) is the correct pattern for accessing PyQt properties in QML—no method call parentheses are needed.Likely an incorrect or invalid review comment.
