    hey,

    i have airtime 2.0.3 and on silence i want liquidsoap to start broadcasting. 
    only that i want it to play from a certain folder between certain hours. i have folders for each of the shows and adapted a script for the ls_script.liq
    still, it seems i have something wrong (i don't know to code). could someone tell me where? 


    #default = amplify(0.00001, noise())
    #default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)

    playlist1 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst1/")
    playlist2 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst2/")
    playlist3 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst3/")
    playlist4 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst4/")
    playlist5 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst5/")
    playlist6 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst6/")
    playlist7 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst7/")
    playlist8 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst8/")
    playlist9 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst9/")
    playlist10 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst10/")
    playlist11 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst11/")
    playlist12 = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/plst13/")


    default=fallback([ 
    switch([
    ({ 0h-2h}, playlist1),
    ({ 2h-3h}, playlist2),
    ({ 3h-4h}, playlist3),
    ({ 4h-5h}, playlist4),
    ({ 5h-8h}, playlist5),
    ({ 8h-10h}, playlist6),
    ({ 10h-11h}, playlist7),
    ({ 11h-13h}, playlist8), 
    ({ 13h-14h}, playlist9),
    ({ 14h-17h), playlist10),
    ({ 17h-19h}, playlist11),
    ({ 19h-20h}, playlist12),
    ({ 20h-22h}, playlist10),
    ({ 22h-0h}, playlist13)
    ])
    ])

    You shouldn't need to have the switch statement nested in a fallback. Just remove the fallback part. Also you should probably try running 

    "sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap"

    from the command-line so you can see any error messages.

    Any time I modify ls_script.liq, I like to run:

    sudo tail -f /var/log/airtime/pypo-liquidsoap/ls_script.log

    and watch for problems. I like Martin's suggestion too because it let's you see everything liquidsoap is doing, although the amount of information can be a little overwhelming because it's generated so quickly.

    hey,

    thanks for your answers. 
    @martin: when removing the fallback part, you suggest smth like this
    default= switch([
    ({ 0h-2h}, playlist1),
    ({ 2h-3h}, playlist2),
    ({ 3h-4h}, playlist3),
    ({ 4h-5h}, playlist4),
    and so on...?

    i'll try this out and keep you posted.

    thanks a lot!

    stefan@station-1501:~$ sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoapLine 55, char 3 before "(": Parse error!


    line 55 is the second one after the switch function
        ({ 2h-3h}, plst2)

    and this is the final script:

    default=switch([
        ({ 0h-2h}, plst1)
        ({ 2h-3h}, plst2)
        ({ 3h-4h}, plst3)
        ({ 4h-5h}, plst4)
        ({ 5h-8h}, plst5)
        ({ 8h-10h}, plst6)
        ({ 10h-11h}, plst8)
        ({ 11h-13h}, plst9)
        ({ 13h-14h}, plst10)
        ({ 14h-17h), plst11)
        ({ 17h-19h}, plst12)
        ({ 19h-20h}, plst13)
        ({ 20h-22h}, plst14)
        ({ 22h-0h}, plst15)
    ])

    what's wrong?

    hey I'm not a liquidsoap expert, but I think you just need commas after each item, I'm checking the example switch on liquidsoaps documentation and they write it like this

    switch([ 
    	({0h-7h}, night), <-- commas separating items before the end
    	({7h-24h}, day) 
    ])

    try this:

    default=switch([ 
        ({ 0h-2h}, plst1) ,
        ({ 2h-3h}, plst2) ,
        ({ 3h-4h}, plst3) ,
        ({ 4h-5h}, plst4) ,
        ({ 5h-8h}, plst5) ,
        ({ 8h-10h}, plst6), 
        ({ 10h-11h}, plst8), 
        ({ 11h-13h}, plst9) ,
        ({ 13h-14h}, plst10), 
        ({ 14h-17h), plst11) ,
        ({ 17h-19h}, plst12) ,
        ({ 19h-20h}, plst13) ,
        ({ 20h-22h}, plst14) ,
        ({ 22h-0h}, plst15) 
    ])

    @ naomi: i tried the commas as you suggested but no chance. liquidsoap still encounters a problem and won't work :/

    Is there another error you are getting now?

    what does your new script look like now? I saw you used to name playlists like this above "playlist1", but now it's "plst1"

    well, the only changes i made to the script are the folder names and the playlist titles. 
    some folders are named unu, doi, trei, patru, cinci, sase and the rest are plst1, plst2 (just testing-purposes)

    but the rule will apply from now on: 'playlistX' is the name of the playlist while plstX is the folder assigned to it.

    You should run the script and post the errors Liquidsoap points out. Only that will help debug the problem

    Ok, so you simply need to look at line 55 and post that here. Otherwise we can't help you :)

    now i get this:

    sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap

    At file /etc/airtime/liquidsoap.cfg, line 46, character 19: The variable
      dj_live_stream_mp defined here is not used anywhere in its scope.
      Use ignore(...) instead of dj_live_stream_mp = ... if you meant
      to not use it. Otherwise, this may be a typo or a sign that your script
      does not do what you intend.

    Reply to @stefan+s:

    Exactly as the error message says, there is a variable that isn't being used, and so Liquidsoap is refusing to start.

    Did you remove a part of the code that uses this variable?

    yes, i managed to make it work.
    it seems that the script didn't work because i used a playlist twice from 12h to 14h and then again from 15h to 17h. i wanted it to be this way but liquidsoap didn't like it so i renamed it (still, it plays music from the same folder under a different name).
    thanks everyone!
