How to use cross.simple?

[rrolla]

Im trying to use cross.simple with no luck

OS: ubuntu:20.04 on docker
Liquidsoap versions: 2.0.0 - 2.0.1 installed from deb package

def transition(a,b)
  if b.metadata["source"] != "music" then
    cross.smart(fade_in=0.5, fade_out=0.1, a, b)
  else
    # Else, apply the standard fade
    # cross.smart(fade_in=7., fade_out=3., a, b)
    cross.simple(fade_in=7., fade_out=3., a, b)
  end
end

Error:

At /home/liquidsoap/config/radio-to-icecast.liq, line 95, char 27-37:
Error 5: this value has type
(_.{source : source(_), db_level : _, metadata : _}, ...) -> _ (inferred at /home/liquidsoap/config/radio-to-icecast.liq, line 82 char 0 - line 92 char 3)
but it should be a subtype of
(_.{source : unit}, ...) -> _

I tried also give a little nudge to the typechecker cross.simple(fade_in=7., fade_out=3., (a:source), (b:source)) but the same error

Interesting that for example above cross.smart works without any tricks

Still, no answers, looks like hard to solve :(

I think it should be:

def transition(a,b)
  if b.metadata["source"] != "music" then
    cross.smart(fade_in=0.5, fade_out=0.1, a, b)
  else
    # Else, apply the standard fade
    # cross.smart(fade_in=7., fade_out=3., a, b)
    cross.simple(fade_in=7., fade_out=3., a.source, b.source)
  end
end

cross.simple takes only transition sources while cross.smart takes the whole source/db level/metadata as it might use any of that.

Huge thanks will try.
