;;; playall --- Play everything in my music collection in random order
;;; Commentary:
;; Uses `systemctl' to determine if MPD is active, and if so uses
;; `mpc' to clear the current playlist, add all the songs in MPD's
;; database to the current playlist, shuffle it and then start
;; playing.
;;; Code:
(define mpd-state
(let ((raw-state
(run/string (systemctl --no-pager -p ActiveState show mpd))))
(substring raw-state
(+ (string-index raw-state #\=) 1) ; After the `='
(- (string-length raw-state) 1)))) ; Before the `\n'
(if (string<> mpd-state "active")
(begin
(format
#t "MPD is not active, state is reported as \"~a\".~%" mpd-state)
(exit 1)))
(run (mpc clear))
(fork/pipe (lambda () (run (mpc listall))))

(mpc shuffle)
