feat(ipc): report live radio metadata in status - #319
Merged
Conversation
A stream's playlist entry only carries the station name, so status reported that with no artist while the TUI showed the actual song. Stations broadcast now-playing text inline as ICY metadata (the StreamTitle field of the SHOUTcast/Icecast protocol), which the UI polls but never reached the IPC response. Apply the UI's own resolution in both the TUI and daemon status handlers, and add TrackInfo.StreamTitle (the raw StreamTitle value) plus TrackInfo.Station so a client can show station, artist/song, and progress together. Resolved at the status handlers rather than in ipcTrackInfo/trackInfo, since only the now-playing track has stream context.

A StreamTitle of "Artist - " cuts to an empty title, which blanked the display instead of falling back to the station name. Guard the split in resolveTrackDisplay (fixing the TUI and Lua events too, not just status) and in the daemon, and derive Station from the resolved title so both paths agree. Also handle a stream title with no artist in the docs jq example. Addresses review feedback on bjarneo#319.

Extract the daemon's stream branch into applyStreamTitle so the test exercises the real implementation rather than a copy of it, and cover the "Artist - Title", "Artist - ", title-only, no-metadata, and non-stream cases. statusResponse needs a live player, so the helper is the seam. Also guard the docs jq example against a missing .track, which printed a literal "null" when nothing was loaded. Addresses review feedback on bjarneo#319.

Summary
For a radio stream,
cliamp statusreported only the station name and no artist, while the TUI displayed the actual song playing. Stations broadcast their now-playing text inline in the audio stream as ICY metadata (theStreamTitlefield of the SHOUTcast/Icecast protocol), and the UI already polls it — but it never reached the IPC response, because the status handlers buildTrackstraight from the playlist entry, and a stream's entry only knows the station name. Any client on the IPC socket (status bars, Waybar, scripts) had no way to show what was playing.This applies the UI's own resolution (
resolveTrackDisplay) in both status handlers and adds twoTrackInfofields:stream_title— the rawStreamTitlevalue, unsplit, for clients that would rather parse it themselvesstation— the playlist entry's own name, kept becausetitle/artistget overwritten by the live values, so a client can show station and songcliamp status, before and after, on the same station:The same fields in
status --json, after:Resolution happens at the status handlers rather than inside
ipcTrackInfo/trackInfo, since only the now-playing track has stream context — search results and queue listings share those helpers and must keep their stored titles. Both the TUI (ui/model/update.go) and the headless daemon (daemon.go) had the same gap, so both are fixed.Existing fields are unchanged and the new ones are
omitempty, so this is additive for existing clients.Providers marked
Stream: trueRadio is not the only source flagged as a stream. Navidrome, Plex, Jellyfin, Emby, Qobuz, NetEase, and Audiobookshelf all set
Stream: true, so they take the same branch. They are unaffected:m.streamTitleis cleared on every track change (ui/model/playback.go) and the override requires a non-empty value, so their own title, artist, and album come through untouched. A test pins that.Local files, Spotify, SoundCloud, and YouTube Music do not set the flag and never enter the branch at all.
