Just schedule one daily show from 00:00 to 24:00 and link the show. (max length of a show currently is 24hrs)
Then create a playlist with the 300 files looped in it. And add this content to the show.
ready-to-go, with correct Metadata.

so why messing around in liquidsoap for that? or do you have any further reasons to do this by fallback?

cheers

Let me Answer Question Two First

The information is in this post http://forum.sourcefabric.org/discussion/15949/icecast-current-song-unknown
that I replied to.

All you have to do is

#default = rewrite_metadata([("title", !ref_off_air_meta)], default)

default = rewrite_metadata([(!ref_off_air_meta,"artist" ),("-","title" )], default)

And Now for Question 1
You can get the information from the logs for each song by tailing the liquidsoap logs

sudo airtime-log -t liquidsoap

A song is played out like this

10 seconds before its start The song is decoded
Then its played Prepared
Then its finished

Here is a synopsis of my log

2013/10/04 19:31:10 [decoder:3] Method "MP3" accepted "/srv/backup/music/K.Rich - Wine Back .mp3".

2013/10/04 19:31:20 [music:3] Prepared "/srv/backup/music/K.Rich - Wine Back .mp3" (RID 13).

2013/10/04 19:35:55 [music:3] Loading playlist...

2013/10/04 19:35:55 [music:3] Playlist is a directory.

2013/10/04 19:36:06 [music:3] Prepared "/srv/backup/music/Bunji We Ready For De Road.mp3" (RID 18).

Look at the ones I highlighted and notice the next one we ready

You could use one of the many log viewer , but for security purpose use on localhost,behind a firewall or not at all.

In old days I used to Use EBOX,I donot know if it still exist .and I do not know how compatible they are with airtime

Json can also be used I will look at that code and hope you will too

To achieve randomness you could use Smart Blocks.
First create a few smartblocks containing your tracks.
Then create a 24-hour-playlist and drag the smartblocks into this playlist.
You could also combine different smartblocks in this playlist.
Then add this Playlist to a 24hr-Show-Slot and don't forget to link this show.

Then you should be fine.

If you won't take advantage of Airtimes functions and want to hack ls_script.liq, you could also use Liquidsoap standalone.

btw - this info should answer both of your questions ;-)

Voisses Tech

@homax queried;

"i need to play random file every day it's "HIT RADIO" "
if you use the simple script but put your songs in different sub folders below your main music folder and set the reload paramaters to a lower value
I also put more elaborate scripts to switch at different time of the day or day of the week (there are many others in this forum also)

@homax queried also;
"what's "New client: localhost "?"
thats the connect between liquidsoap and the server,its the way they communicates,so thats perfectly ok

@hoerich suggested;

"If you won't take advantage of Airtimes functions and want to hack ls_script.liq,"

on the contrary it does,but it does not take advantage of the interfaces
The fallback is one way,if you also use the input script I wrote you can also make it interacts totally with s3 input for stream.That is why I say put it at the bottom cause it can be modify.

@hoerich futher suggested;

"you could also use Liquidsoap standalone."

Why would you?,Airtime has done all the watchdog script and many other python scripts you can leverage on. With a standalone you would literally have to do all your error handling on your own.
And how would a newbie do this and have it fall back to Airtime schedules etc?

One other thing I am keen on,How would a newbie place a Standalone Liquidsoap on a Airtime Machine?.
Most people who suggest that is saying put it between Airtime and Icecast.This total waste of time,If you have to do that Just Use butt or any other and then you could use Itunes etc as playout.

Scripts Are An ever functional part of radio Automation,like Pal for Sams,Rml for rivendell,python and perl for many others and people should use it to enhance what they want.

Take for instance,the seek function [play and stop] is limited (t have to be specific) but customisable in Liquidsoap but you can script it and use it in the fallback

My contention is that scripts should never be a substitute for the Software.

Ps.
by the way there is a way to use the fallback externally that should Airtime ls script change it does not smash the fallback {soon post it)

I think, homax could achieve his goal without messing around in ls_script.liq
So I suggested to try it with Airtime's buitl-in-functions (linked Smart-Blocks)
Or maybe use Liquidsoap alone, since he seems not to have a lot demands.
I don't know about his skills. These were just advices he should think of...

You Know I am always trying that multiple quotes thing.I need to try harder.
:bz
You know originally I thought about just putting a Standalone script,but I like Airtime and that is why I tried and integrate the scripts to fit it.
I felt Airtime is constantly changing and it gives greater opportunities if I had an integrated approach
Here is Where I am

I now only put 4 lines in the Ls_script
I can now change my fallback playlist and schedules on the fly ( I tested it 10062013)
with my new found skills in python,I can shut down and restart the script without the listener hears the change
I can seek,restart ,pause and rewind a song ,just need to test this more

Developers at Airtime will make changes if Our expectation Gap meets the Reality Gap of the software.

Airtime especially Lisa and the team listen a lot and that is why Airtime version Changes are so rapid.

Many developers just ignore you.like RED5. I now use a different server but I would have like to use REd

Thanks for your Suggestion and I hope @homax will enjoy Airtime
