Channel sync

A channel you follow does not want re-listing from the beginning every time. The channels tab of S keeps the ones you want, with the day each was last synced:

key	does
N	add a channel, type its url
Enter	edit the url
D	edit the last sync date, 2024-01-31 or 20240131
X / Del	drop the channel
S	sync this channel and pick from what it finds
Shift+S	sync every channel

Shift+S works in the main view too, without opening the panel.

Syncing lists everything the channel uploaded between its last sync and today, into the queue you are looking at, and then moves the last sync to today, whether or not you queue what comes back, so nothing is listed twice by accident. A channel that has never been synced has no lower bound, so the first sync is the whole channel. Set its date by hand with D to start from a day you choose.

One channel opens the picker, so you see the entries before they are queued. Shift+S does not: one picker cannot show several channels at once, so every entry found is queued. Either way the cutoff is honoured exactly, and the two-pass listing in the playlist picker is what keeps that cheap.

The list is ~/.config/muxget/channels, in the same small TOML subset the rules file uses, and hand-editing it works as well as the panel:

# ~/.config/muxget/channels

[[channel]]
url = "https://www.youtube.com/@veritasium"
last_sync = "20260601"

The date is a day, not a moment: a video uploaded later on the day of a sync is listed again by the next one. yt-dlp's --download-archive, set in the yt-dlp options, is what stops it downloading twice.

Next: queues and schedules.
