Build Cleanup & Release Packaging

Date: 2026-09-22 13:39 Commits: 4bf6545..1ea7f19 (5 commits)

Task Description

Resolved all build warnings/errors across the frontend (svelte-check, Vite) and backend (cargo), fixed a failing test, and implemented a release build script that produces a distributable GUI Video Clipper.app bundle.

Changes Made

Task 1: TypeScript Error Fixes (3eebe01)

• Installed @types/node as dev dependency
• Added "types": ["node"] to tsconfig.json
• Changed defineConfig import in vite.config.ts from vite to vitest/config (extends config type with test property)
• Result: 4 TS errors → 0

Task 2: Svelte A11y Warning Fixes (9d1f1cf)

• CaptionSettingsPanel.svelte: 9 label/control association fixes (id/for pairs and wrapping)
• ClipList.svelte: Added tabindex="0" and keyboard handler to listbox container
• PreferencesPanel.svelte, ExportDialog.svelte, AboutDialog.svelte: Added tabindex="-1" to dialog divs, keyboard handlers on overlays
• VideoPlayer.svelte: Added <track kind="captions" /> to <video> element
• App.svelte: Added keyboard support to resize handle (role="slider", arrow keys, aria-value attrs)
• Result: 19 a11y warnings → 0

Task 3: Rust Dead Code Annotations (d85fbda)

• Added #[allow(dead_code)] with comments on 6 items across 4 files:
  • ExportEvent::Error, DownloadEvent::Error (reserved for future use)
  • sanitize_vtt_for_ffmpeg, opacity_to_ass_back_colour, caption_style_to_force_style (caption burn-in pipeline)
  • SubtitleFormat.ext/.url (serde deserialization fields)
• Result: 6 warnings → 0

Task 4: Test Fix (30b04b4)

• Changed markInPoint(5) to markInPoint(12) in clips.test.ts
• Time 5 was outside EDIT_TOLERANCE (0.5s) of clip boundary (10-20), so isTimeInsideClip returned false and the edit path didn't execute
• Result: 1 failing test → 31/31 pass

Task 5: Release Build Script (1ea7f19)

• Created scripts/build-release.sh: builds, ad-hoc signs, copies to dist/release/
• Changed tauri.conf.json bundle targets from "all" to ["app", "dmg"]
• Added dist/ to .gitignore
• Added "release" npm script
• Updated README with Release Build section
• Script parses tauri build output for .app/.dmg paths (handles custom CARGO_TARGET_DIR)
• Result: npm run release → GUI Video Clipper.app (6.2M) + .dmg (2.8M)

Verification Results

• npm run check: 0 errors, 0 warnings
• npm test: 31/31 pass
• cargo build: 0 warnings
• npm run release: produces signed .app + .dmg

Lessons Learned

• Cursor sandbox CARGO_TARGET_DIR: The Tauri build outputs to a sandboxed cache directory, not src-tauri/target/. The build script must parse the actual output paths from npx tauri build output rather than hardcoding the expected location.
• Svelte a11y linter strictness: role="separator" with keyboard support still triggers a11y_no_noninteractive_element_interactions. Using role="slider" satisfies the linter for resize handles.
• Dialog overlay keyboard patterns: Adding onkeydown + tabindex="-1" to overlays and e.stopPropagation() to inner dialogs satisfies the click-needs-keyboard-equivalent rule, but the stopPropagation means Escape from inside the dialog won't bubble to the overlay handler. Not a regression since dialogs previously had no keyboard close.
• Test EDIT_TOLERANCE awareness: When testing functions that use proximity checks (isTimeInsideClip), test values must account for tolerance thresholds. Values outside tolerance trigger different code paths.

Follow-up Items

• Push new commits to remote: git push origin master
• Consider re-tagging v0.1.0 to include these cleanup commits, or tag as v0.1.1
• Dialog Escape-from-inside behavior could be improved in a future pass (add Escape handler on the dialog div itself, not just the overlay)
