Review Change Stack

📝 Walkthrough

Walkthrough

Adds configurable synced lyrics downloading. The renderer sends lyrics and song metadata through IPC. The backend formats and saves an .lrc file, then reports success, cancellation, or errors.

Changes

Synced Lyrics Download

Layer / File(s) Summary
Download configuration and menu
src/plugins/synced-lyrics/types.ts, src/plugins/synced-lyrics/index.ts, src/i18n/resources/en.json, src/plugins/synced-lyrics/menu.ts
Adds enableDownload, enables it by default, and adds a localized download checkbox.
LRC formatting and IPC save flow
src/plugins/synced-lyrics/backend.ts
Formats timed or plain lyrics, opens an .lrc save dialog, writes UTF-8 content, validates IPC payloads, and cleans up the handler.
Renderer download control
src/plugins/synced-lyrics/renderer/components/LyricsPicker.tsx, src/plugins/synced-lyrics/style.css
Adds the conditional download button, metadata forwarding, result toasts, corrected navigation styling, and shared button styling.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 869ed

The new lyrics download feature can create a metadata-only .lrc file and omit plain lyrics when synced-lyrics data contains an empty line list, while some download messages remain English in non-English interfaces. The PR is mergeable with explicit owner follow-up for these bounded issues.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Treat an empty line array as no timed lyrics.

An empty lines array is truthy. The renderer then shows the save button, and the backend selects the timed branch. This produces an LRC file with only metadata, and it also drops available plain lyrics.

  • src/plugins/synced-lyrics/backend.ts#L27-L35: use data.lines?.length before formatting timed lines so empty arrays fall back to data.lyrics.
  • src/plugins/synced-lyrics/renderer/components/LyricsPicker.tsx#L351-L355: require currentLyrics().data?.lines?.length before showing the button for timed lyrics.

Localize the new save messages and tooltip.

Move these strings to translation resources and retrieve them through t(). The related menu is localized, but the success, cancellation, failure, and button tooltip text remain English in non-English interfaces.
