--- phase: 18-batch-edit plan: 02 subsystem: ui tags: [lit, batch-edit, track-details, three-state, progress, wails] # Dependency graph requires: - phase: 18-batch-edit/01 provides: BatchWriteTrackTags method, CancelBatchWrite, BatchWriteProgress event, BatchResult types - phase: 17-single-track-edit provides: Track-details dialog, single-track edit flow, cover art editing, WriteTrackTagsByPath pipeline provides: - Batch edit mode in track-details component (showBatch API) - Three-state field model (keep/set/clear) via dirty-tracking editValues - Confirmation dialog with change summary before batch save - Live progress bar with "N of M" counter during batch writes - Batch cancel button wired to CancelBatchWrite - Results view with success/failure counts and expandable failure details - Batch cover art pick/clear for all selected tracks - All 4 view components (track-list, cover-grid, queue-panel, playlist-details) dispatch to showBatch for multi-select affects: [19-ogg-vorbis] # Tech tracking tech-stack: added: [] patterns: [getMergedFields for batch field aggregation, three-state implicit dirty tracking, confirmation overlay pattern, Wails EventsOn/Off for progress streaming] key-files: created: [] modified: - frontend/src/components/track-details/track-details.ts - frontend/src/components/track-list/track-list.ts - frontend/src/components/cover-grid/cover-grid.ts - frontend/src/components/queue-panel/queue-panel.ts - frontend/src/components/playlist-details/playlist-details.ts key-decisions: - "Three-state field model via implicit editValues dirty tracking — untouched fields not in editValues (keep), typed fields in editValues (set), cleared fields in editValues with empty string (clear)" - "Confirmation overlay within dialog rather than separate dialog — simpler implementation, consistent UX" - "Field labels added to all track-details states for consistency (single/batch, read/edit)" patterns-established: - "showBatch(tracks, coverArt, coverArtMixed) as public batch entry API alongside existing show()" - "getMergedFields() for computing shared vs mixed values across N tracks" - "openBatchTrackDetails(filePaths) method pattern on each view component" requirements-completed: [BATCH-01, BATCH-02, BATCH-03, BATCH-04] # Metrics duration: ~30min completed: 2026-03-18 --- # Phase 18 Plan 02: Frontend Batch Edit UI Summary **Batch edit mode in track-details dialog with three-state field editing, merged value display, confirmation guard, live progress bar, partial failure reporting, and batch cover art — wired from all 4 view context menus** ## Performance - **Duration:** ~30 min (across checkpoint session) - **Started:** 2026-03-18T17:02:40Z - **Completed:** 2026-03-18T18:30:00Z - **Tasks:** 3 (2 auto + 1 checkpoint:human-verify) - **Files modified:** 5 ## Accomplishments - Track-details component extended with full batch mode: showBatch() API, merged field summary, three-state editing, confirmation dialog, progress bar with Wails event streaming, results view with failure details, batch cover art - All 4 view components (track-list, cover-grid, queue-panel, playlist-details) branch on selection count — 1 track → single mode, 2+ tracks → batch mode via openBatchTrackDetails - Field labels added to all track-details states (single/batch, read/edit) for consistency - Human verification confirmed all batch edit flows work: summary view, editing, confirmation, progress, results, cover art, and single-track regression ## Task Commits Each task was committed atomically: 1. **Task 1: Add batch mode to track-details component** - `6dab32b` (feat) 2. **Task 2: Update all view context menu handlers for batch mode** - `656985a` (feat) 3. **Task 3: Verify complete batch edit flow** - checkpoint:human-verify (approved) Additional fix commits during verification: - `9df2d67` — fix(18-02): add field labels above title/artist/album inputs in batch edit mode - `d430ad8` — fix(18-02): add field labels to all track-details states (single/batch, read/edit) ## Files Created/Modified - `frontend/src/components/track-details/track-details.ts` — Batch mode: showBatch(), getMergedFields(), three-state editing, confirmation overlay, progress bar, results view, batch cover art, field labels - `frontend/src/components/track-list/track-list.ts` — openBatchTrackDetails with album-based cover art resolution - `frontend/src/components/cover-grid/cover-grid.ts` — openBatchTrackDetails with album-based cover art resolution - `frontend/src/components/queue-panel/queue-panel.ts` — openBatchTrackDetails resolving queue tracks to library tracks - `frontend/src/components/playlist-details/playlist-details.ts` — openBatchTrackDetails with album-based cover art resolution ## Decisions Made - Three-state field model implemented via implicit dirty tracking in editValues map — no explicit "state" enum needed; the existing onEditInput handler naturally creates the keep/set/clear distinction - Confirmation dialog implemented as an overlay within the existing dialog rather than spawning a second dialog — simpler DOM management and consistent visual context - Field labels added across all track-details rendering states (not just batch edit) during verification for visual consistency ## Deviations from Plan ### Auto-fixed Issues **1. [Rule 1 - Bug] Added field labels to batch edit inputs** - **Found during:** Task 3 (human verification checkpoint) - **Issue:** Batch edit mode inputs lacked field labels, making it unclear which field was which - **Fix:** Added visible labels above title/artist/album inputs in batch edit mode - **Files modified:** frontend/src/components/track-details/track-details.ts - **Verification:** Visual inspection in running app - **Committed in:** `9df2d67` **2. [Rule 1 - Bug] Added field labels to all track-details states** - **Found during:** Task 3 (human verification checkpoint) - **Issue:** After adding labels to batch edit, single-track mode also lacked consistent labels - **Fix:** Added field labels to single-track read and edit modes for consistency - **Files modified:** frontend/src/components/track-details/track-details.ts - **Verification:** Visual inspection confirming labels appear in all 4 states (single read, single edit, batch read, batch edit) - **Committed in:** `d430ad8` --- **Total deviations:** 2 auto-fixed (2 bugs — missing UI labels) **Impact on plan:** Both fixes improve usability. No scope creep — labels were implicit in the plan's field display requirements. ## Issues Encountered None ## User Setup Required None - no external service configuration required. ## Next Phase Readiness - Phase 18 complete — all batch edit requirements (BATCH-01 through BATCH-04) fulfilled - Phase 19 (OGG Vorbis Tag Writing) can proceed independently — depends on Phase 16 backend, not Phase 18 ## Self-Check: PASSED All 5 key files verified on disk. All 4 task/fix commits (6dab32b, 656985a, 9df2d67, d430ad8) verified in git log. --- *Phase: 18-batch-edit* *Completed: 2026-03-18*
