Hi, Your code is equivalent to
if '$(if $(display_title),"$(display_title)","blank")' == "blank" then source2 = drop_metadata(source) end and you don't use source2 in the following. In your script, the name "source2" just happens to be "source" but the orginial source isn't changed: a new source, without metadata is createad, and you don't use it. Thus the (justified) error. So, I don't think that your approach can be made to work. In your case, I would use map_metadata with something like (untested): def drop_blank_title(m) = if m["title"] == "" then [] else m end source = map_metadata(drop_blank_title, source) The metadata are always mapped. They just happend not to be changed when the title is not "". ++ Sam. 2011/10/30 KJ Koning <[email protected]>: > In my Liquidsoap script, I am using map_metadata to send the title and > artist from annotate instead of ID3 tags.
