ok, thanks, got the basic concept.
def agent() =
# myscript returns one line with an URI or nothing
r = list.hd(get_process_lines("myscript"))
# Create and return a request using this result
request.create(r)
end
dyn = request.dynamic(agent)
radio = [dyn, playlist, secure]
this works as long as myscript returns an URI. how to deal with null
output, i.e. no URI available? execution of myscript then results in
a complaint: [request:3] Nonexistent file or ill-formed URI ""!
what should happen is that the dynamic request source simply fails and
playlist takes over. must be something simple... tips appreciated,
thanks, udo
