[Savonet-users] interpolate string in output.file filename

[Tony M. <mcf...@gm...>]

Hi,

I'm trying to interpolate a ref "" in the filename for output.filename:

output.file(%mp3,
"/mnt/wat/datafruits-#{current_dj}-%d-%m-%Y-%H:%M:%S.mp3",
live_dj,fallible=true)

which gets set in my auth function for input.harbor:

def dj_auth(user,password) =
  u = get_user(user,password)
  p = get_password(user,password)
  #get the output of the php script
  ret = get_process_lines("bundle exec ./dj_auth.rb #{u} #{p}")
  #ret has now the value of the live client (dj1,dj2, or djx), or
"ERROR"/"unknown"
  ret = list.hd(ret)
  #return true to let the client transmit data, or false to tell
harbor to decline
  if ret == "true" then
    title_prefix := "LIVE NOW ♫✩ -- #{u} ✩♪"
    current_dj := "#{u}"
    true
  else
    false
  end
end

live_dj = input.harbor("datafruits",port=9000,auth=dj_auth,on_disconnect=on_disconnect)

But when I see the filename its simply this:
  datafruits-ref("")-08-09-2013-20:08:45.mp3

I'm guessing the string is only interpolated at the beginning of the
script being run, or its interpolated before the dj_auth function is
run. Any ideas?

Also I noticed this in the docs for output.file:
(unlabeled) (string): Filename where to output the stream. Some
strftime conversion specifiers are available: %SMHdmY. You can also
use $(..) interpolation notation for metadata.

What does it mean by $(..), was that supposed to be #{..} ?

Thanks again,
