Vivienne

macOS Spotify (and maybe not only Spotify) scrobbler for a self-hosted Last.fm-compatible instance

listens to Spotify playback notifications and pushes now playing + scrobble to the instances' Last.fm 2.0 API

how it even works

• reads track metadata directly from Spotify.app playback notifications via NSDistributedNotificationCenter
• authenticates once with auth.getMobileSession (your instance username + password), caches the session key in .vivienne_session
• sends track.updateNowPlaying when a track starts
• sends track.scrobble once per play, using the standard Last.fm threshold: track longer than 30s, played to half its length or 4 minutes (whichever comes first)

setup

cp config.example.toml config.toml   # then edit username/password
cargo build --release
./target/release/vivienne

config is looked up in this order: $VIVIENNE_CONFIG, ./config.toml, ~/.config/vivienne/config.toml

install

cargo install --path .
