debussy
CLI emitting json when song changes on Linux. Uses MPRIS and dbus to receive events
demo
In the example below, I'm using the Gnome application Shortwave to listen to internet radio. The app is detected, and then each track change is received, and logged, and a json payload generated:
$ RUST_LOG=info debussy
INFO debussy > Found Shortwave (on bus org.mpris.MediaPlayer2.de.haeckerfelix.Shortwave)
INFO debussy > Radio Paradise (320k)::::Mark Knopfler - Don't You Get It
{"player":"Radio Paradise (320k)","artist":"Radio Paradise (320k)","title":"Mark Knopfler - Don't You Get It"}
The logs go to stderr, but the json goes to stdout. This means that output can be received by other tools in a unix pipeline. For example, streaming the json data to the program jq:
$ debussy | jq
