[Feature request]: Watch changes in a remote playlist

[iSerganov]

At the moment reload_mode="watch" is not supported by remote playlists.

And it would be super nice feature to have!

Until it is implemented, the workaround is to put a script like this into your Liquidsoap container:

while [ true ]
do
    if test -e "$PLAYLIST_PATH"
    then zflag="-z $PLAYLIST_PATH"
    else zflag=
    fi
    curl -o /playlist.pls $zflag $PLAYLIST_URL
    sleep $INTERVAL_SECONDS
done

And my .liq file contains playlist definition as follows:

myplaylist = playlist(environment.get("PLAYLIST_PATH"),reload_mode="watch")

My suggestion is to make reload_mode="watch" working with remote playlist by periodically fetching it and reloading when the newer version is available. Periodic fetching interval can be defined through a parameter, e.g. refresh_interval=10 (fetch remote playlist every 10 seconds).

Hi!

Thanks for submitting. While we should probably add this to the operator, you can always implement it by using the reload method of the playlist source:

s = playlist("...")
# Check on the remote playlist
s.reload()

Yes and no.
Yes - it will reload the playlist, no - it won't do it every time a change happens to the remote playlist.

You can always use thread.run to run a recurrent check inside your own liquidsoap script.
