PS. Don't forget to download the sound
file! DS.
Remember the discussion where I said the computer
should be silent? Only the huge fan of the
nearby industrial plant, or the lazy buzz of
the starship engine, should make for a pleasant
trip to the oldest galaxies of the universe...
Anyway, I think it was I that came up with the
rule, that there isn't a rule without an
exception, so I decided to play a sound from
Emacs whenever I use a function to check the
integrity of the system, if the check turns
out OK!
So far, what happens is, it calls a shell
function. I actually happen to know, that that
is a fine way of doing it. Even so, it would be
interesting to hear of other ways and/or
interfaces that you are familiar with!
Here is the code:
(shell-command "omx-play-sound ~/bo/up.mp3")
;; Here is the sound file (89K) - bonus points
;; if you can identify the two parts :)
;;
;; http://user.it.uu.se/~embe8573/sounds/up.mp3
;; Here is the zsh function, in a file that is
;; 'source'd from ~/.zshenv to be visible from
;; Emacs:
;; omx-play-sound () {
;; local -a files
;; files=($@)
;;
;; check-files $files # error checking, never mind it
;; (( $? == 1 )) && return 1
;;
;; local vol=200
;;
;; for f in $files; do
;; sudo omxplayer \
;; --adev local \
;; --vol $vol \
;; $f \
;; > /dev/null # no verbose option in omxplayer(1)
;; done
;; }
