Hello Nick!
YES! Thanks a lot! That was exactly what I was looking for.
I'll follow up with my finished script in a few days as others mithg
find it instructive. :)
Just wanted to let you know things work fine now!
Best regards,
René

Hi Rene,
I think your problem is how to reference variables defined outside a
function OCAML handles scope.
To increment a number inside a function should be done like that.
timesplayed = ref 1
def bumpcounter () =
timesplayed := !timesplay + 1
end
Note the 'ref' when you define the variable in the main program
Then to use that variable inside the function, you need to prefix it
with !
and to set it, you use := instead of just =
Hope this helps.

Hello Everyone,
Sorry for re-bothering you with this,
But I'm still stuck at the problem I described a few months ago.
Back then, I've been trying to set up a "song counter"
(which would enable me to switch the source to unavailable after
having played like 15 items from playlist / source).
But whatever I tried, I could not get a simple thing like
songsplayed = songsplayed+1
to work.
Now, I just discovered that in latest LiquidSoap, there is the
"time" function, which I think might do the trick just fine.
However, I don't get this one to work either.
Could someone try helping me out once more?
What I try to do:
As soon as my live source goes offline, music should be played for
about 15 minutes.
After 15 minutes, the "music" should become unavailable and
instead, a single file should be played (telling the listeners
that no broadcast is going on).
What I get:
Currently, the line {time - musictime < 300} results in:
this value (referring to: musictime) has type
()->float
but it should be a subtype of
something that is a number type
These are the important lines:
#The stream should start with music
musictime = time
#Transition to live source
def GoLive (old, new) =
source.skip(old)
sequence([old,new])
end
#Transition away from live
def ComeHome(old,new) =
musictime = time
sequence(old,, new)
end
#The soures
offairloop = mksave(playlist("/home/pi/radio/loop"))
themusic = playlist("/mnt/storage/radio/music")
#The switch, where the magic is supposed to happen
nonliveradio = switch (track_sensitive = true, [
({time - musictime < 300}, themusic),
({true}, offairloop)
])
#Later, I'll add the live source, and do a fallback: When live
goes off, switch to nonliveradio...
#But that I think is not important just yet :-(
So once more, I'd appreciate any pointers.
Thanks so much!
And best regards,
René
