iOS doesn't have hover, so the tooltip only ever showed on desktop —
where the share-arrow glyph is universally recognised anyway. Aria-
label stays for screen readers.
Web Share fails silently when iOS' share sheet refuses the payload,
typically because the file exceeds the platform's soft size limit
(~50–100 MB depending on iOS version). The previous patch logged to
the console but the user saw nothing — staring at a button that
'does nothing' is poor UX.
Adds two layers of feedback:
1. Pre-flight size check (SHARE_SIZE_WARN_BYTES = 80 MB, conservative
relative to iOS' actual limit) with a confirm() dialog before the
fetch. Avoids spending bandwidth pulling a 150 MB blob into the
browser only for navigator.canShare to reject it.
2. Surfaces canShare-rejection AND share()-failure as a visible
alert() suggesting the user fall back to the download link next
to the share button.
Tested locally with files from 0.7 MB up to 150.7 MB: small files
share unchanged, the 150 MB file now produces a pre-flight warning
the user can dismiss, and any subsequent rejection produces a clear
alert instead of silently no-op'ing.
Adds a share button to the completed-list action row that hands the
downloaded file off to the platform share sheet via navigator.share().
On iOS Safari/Chrome this surfaces the native Save-to-Photos / Save-to-
Files / AirDrop options for videos and images, and Files / 3rd-party
app targets for audio. On platforms without Web Share support (Desktop
Firefox/Chrome/Safari) the button hides itself; the existing download
link remains the universal fallback.
Implementation notes:
- canShareDownloads() requires both navigator.share AND navigator.canShare
(Desktop Safari has the former without the latter; we always intend
to share a file, not a URL)
- shareDownload() fetches the file via the existing buildDownloadLink()
helper, wraps it in a File, then runs canShare() before share() so we
can bail out cleanly on platforms that reject the MIME type
- AbortError (user dismisses sheet) is silenced; other errors logged
- Tooltip on the button explains the iOS behaviour briefly
Refs alexta69/metube#582 — addresses the 'add to Photos.app' request
without depending on the iOS Shortcut, which has had reliability issues
(cf #763).
P1 fixes:
- _subtitle_lang_list now extracts base language from qualified tags
(e.g. zh-Hans → zh base) so regional variants are still added as
fallbacks. Original input is preserved as first priority.
- DownloadInfo.__init__ now explicitly initializes filename=None and
chapter_files=[] to avoid AttributeError on dynamic attribute access.
- __setstate__ adds filename=None migration for old persistent data.
- Frontend Download interface gains subtitle_files field; completed
downloads show each subtitle file with download link and CC icon.
P2 improvements:
- _LANGUAGE_REGION_VARIANTS expanded from 10 to 30 languages covering
it/ja/ko/hi/th/vi/id/pl/uk/ru/cs/sv/da/no/fi/tr/el/he/hu/bn/ta.
- Languages with no regional variants use empty tuple (they still get
-orig suffix when include_orig=True).
- Reset download_phase when transitioning to paused (pause(), update_status(),
_post_download_cleanup()) so UI shows 'Paused' instead of stale phase label
- Reset download_phase when starting/resuming download (start() preparing state)
- Count 'postprocessing' as active download in updateMetrics() so dashboard
shows accurate counts during ffmpeg post-processing
- Add missing completedDownload Subject to DownloadsServiceStub in app.spec.ts
- Add Download type import to app.spec.ts
Fixes: TypeError Cannot read properties of undefined (reading 'pipe')
at app.ts:300 (completedDownload not in test stub)
- Removed shadow from URL entry wrap in app.html for a cleaner look.
- Updated various icon files to improve visual consistency across the application.
- Add suffix to identify different files of same video
- Fixed invisible download for short link
