Hi.
I just upgraded from v1.1 to 1.4.1 and adjustments need to be made to the
script.
I can't figure out how to update the script in the following case:
*def metadata_playlists(playing_metadata)*
*#on_metadata function *
server_execute_output =
server.execute("#{playing_metadata[\"source\"]}.next")
log("server execute output = "^string_of(server_execute_output))
#the expected output: a list of strings with 12 elements
next_tracks_head = list.hd(server_execute_output)
log("exec output= "^string_of(list.hd(server_execute_output)))
*#the output is <fun>*
Why is the output of list.hd <fun>? I can't figure out what I'm doing wrong.
Thanks.
P.S. Even if I have programming skills, I find it difficult to get used
with liquidsoap and ocaml specific language. What should I read to better
understand it?
