Now... I have to put all of this into a conditional :)
I was thinking of:
s0 =
if source_device == "pulse" then
input.pulseaudio(client='#{stream_name}')
else
input.alsa(device="#{source_device}")
end
s =
if stream_metasource != "disabled" then
# Attach metadata insertion hooks
x = insert_metadata(s0)
insert = fst(x)
s = snd(x)
# A reference to the latest metadata
latest_meta = ref []
#list.append(["coucou"], !latest_meta)
# A function to update metadata
def update_meta() =
data = http.get("http://martin-virtualbox/titles";)
m = [("title", snd(data))]
print(m)
if m != !latest_meta then
latest_meta := m
insert(m)
print("new metadata !")
end
# Restart in 10. seconds
10.
end
# Start polling now
add_timeout(0., update_meta)
s
else
s0
end
(...)
# The output
output = out(id="#{stream_id}", host="#{stream_host}",
port=int_of_string("#{stream_port}"), password="#{stream_password}",
genre="#{stream_genre}", url="#{stream_url}", s)
The problem is the iteration part where I return "s", else s0 ... which
leads to the error:
this value has type
(...)->source(_)
but it should be a subtype of
(...)->active_source(_)
Am I close to it ?
