This is useful for players (e.g mpDris2) that don't regularly update the position. +* `--replace`: By default, new instances will attach to the existing one so that the output is identical. This lets this instance replace any others running. It isn't recommended. * `--send` sends commands to an already running waybar-mpris instance via a unix socket. Commands: * `player-next`: Switch to displaying and controlling next available player. * `player-prev`: Same as `player-next`, but for the previous player. @@ -4,5 +4,9 @@ go 1.15 require ( github.com/godbus/dbus/v5 v5.0.3 + github.com/hpcloud/tail v1.0.0 github.com/spf13/pflag v1.0.5 + golang.org/x/sys v0.0.0-20200928205150-006507a75852 // indirect + gopkg.in/fsnotify.v1 v1.4.7 // indirect + gopkg.in/tomb.v1 v1.0.0-20141024135613-dd632973f1e7 // indirect ) @@ -1,4 +1,12 @@ github.com/godbus/dbus/v5 v5.0.3 h1:ZqHaoEF7TBzh4jzPmqVhE/5A1z9of6orkAe5uHoAeME= github.com/godbus/dbus/v5 v5.0.3/go.mod h1:xhWf0FNVPg57R7Z0UbKHbJfkEywrmjJnf7w5xrFpKfA= +github.com/hpcloud/tail v1.0.0 h1:nfCOvKYfkgYP8hkirhJocXT2+zOD8yUNjXaWfTlyFKI= +github.com/hpcloud/tail v1.0.0/go.mod h1:ab1qPbhIpdTxEkNHXyeSf5vhxWSCs/tWer42PpOxQnU= github.com/spf13/pflag v1.0.5 h1:iy+VFUOCP1a+8yFto/drg2CJ5u0yRoB7fZw3DKv/JXA= github.com/spf13/pflag v1.0.5/go.mod h1:McXfInJRrz4CZXVZOBLb0bTZqETkiAhM9Iw0y3An2Bg= +golang.org/x/sys v0.0.0-20200928205150-006507a75852 h1:sXxgOAXy8JwHhZnPuItAlUtwIlxrlEqi28mKhUR+zZY= +golang.org/x/sys v0.0.0-20200928205150-006507a75852/go.mod h1:h1NjWce9XRLGQEsW7wpKNCjG9DtNlClVuFLEZdDNbEs= +gopkg.in/fsnotify.v1 v1.4.7 h1:xOHLXZwVvI9hhs+cLKq5+I5onOuwQLhQwiu63xxlHs4= +gopkg.in/fsnotify.v1 v1.4.7/go.mod h1:Tz8NjZHkW78fSQdbUxIjBTcgA1z1m8ZHf0WmKUhAMys= +gopkg.in/tomb.v1 v1.0.0-20141024135613-dd632973f1e7 h1:uRGJdciOHaEIrze2W8Q3AKkepLTh2hOroT7a+7czfdQ= +gopkg.in/tomb.v1 v1.0.0-20141024135613-dd632973f1e7/go.mod h1:dt/ZhP58zS4L8KSrWDmTeBkI65Dw0HsyUHuEVlX15mw= @@ -15,6 +15,7 @@ import ( "time" "github.com/godbus/dbus/v5" + "github.com/hpcloud/tail" flag "github.com/spf13/pflag" ) @@ -48,18 +49,21 @@ const ( MATCH_PC = "type='signal',path='/org/mpris/MediaPlayer2',interface='org.freedesktop.DBus.Properties'" SOCK = "/tmp/waybar-mpris.sock" LOGFILE = "/tmp/waybar-mpris.log" + OUTFILE = "/tmp/waybar-mpris.out" POLL = 1 ) var ( - PLAY = "▶" - PAUSE = "" - SEP = " - " - ORDER = "SYMBOL:ARTIST:ALBUM:TITLE:POSITION" - AUTOFOCUS = false - COMMANDS = []string{"player-next", "player-prev", "next", "prev", "toggle", "list"} - SHOW_POS = false - INTERPOLATE = false + PLAY = "▶" + PAUSE = "" + SEP = " - " + ORDER = "SYMBOL:ARTIST:ALBUM:TITLE:POSITION" + AUTOFOCUS = false + COMMANDS = []string{"player-next", "player-prev", "next", "prev", "toggle", "list"} + SHOW_POS = false + INTERPOLATE = false + REPLACE = false + WRITER io.Writer = os.Stdout ) // NewPlayer returns a new player object. @@ -310,7 +314,7 @@ func (pl *PlayerList) Remove(fullName string) { if !found { pl.current = 0 pl.Refresh() - fmt.Println(pl.JSON()) + fmt.Fprintln(WRITER, pl.JSON()) } } // ls[len(ls)-1], ls[i] = ls[i], ls[len(ls)-1] @@ -384,8 +388,10 @@ func main() { flag.BoolVar(&AUTOFOCUS, "autofocus", AUTOFOCUS, "Auto switch to currently playing music players.") flag.BoolVar(&SHOW_POS, "position", SHOW_POS, "Show current position between brackets, e.g (04:50/05:00)") flag.BoolVar(&INTERPOLATE, "interpolate", INTERPOLATE, "Interpolate track position (helpful for players that don't update regularly, e.g mpDris2)") + flag.BoolVar(&REPLACE, "replace", REPLACE, "replace existing waybar-mpris if found.
