if condition add line or not

[caf2022]

Hi, is posible to add a if codition to if variable has not empty then add the normalize line, something like this:

streaming_normalizador_gain_min = -16.0
streaming_normalizador_gain_max = 0.

if(streaming_normalizador_gain_min != "") then
playlist = normalize(target = 0., window = 0.03, gain_min = streaming_normalizador_gain_min, gain_max = streaming_normalizador_gain_max, playlist)
end

Hi.
I'm not sure what's the default value of the streaming_normalizador_gain_min variable and how you will modify it.
I can assume that it can be null or float - float?.

Let's define functions that will return actual gain values.
They will return float or null because of random.

def get_gain_min()
  if random.bool() then
    0.
  else
    null()
  end
end

def get_gain_max()
  if random.bool() then
    0.
  else
    null()
  end
end

Then I have to do something with source.
Let's name it r and make it play sine.

r = sine()

The I'll get the gain values

gain_min = get_gain_min()
gain_max = get_gain_max()

Probably this is what you asking about.
If gain_min is not null and gain_max is not null then return normalize.
Else return itself.

r = if (null.defined(gain_min) and null.defined(gain_max)) then
  normalize(gain_min=null.get(gain_min), gain_max=null.get(gain_max), r)
else
  r
end

After that I want to get r.id().
If it was normalized, then I'll see amplify_*, else sine_*

print(r.id())
output.dummy(r)

You could share a more detailed code sample so we could discuss it further.
