declare name	"Sirius_5h5p_allrad";

leads to this error in Supercollider once the server is booted and the UGen is instantiated:

exception in GraphDef_Recv: UGen 'Sirius5h5pallrad' not installed.
*** ERROR: SynthDef temp__0yo-1600951377_1008 not found

While trying to get this to work, I found my python version was outdated. Apparently python 3.8 is needed for the shutil.copytree commands to work (more specifically the dirs_exist_ok argument).

So a fix would be to either document that python 3.8 is needed, or make a workaround to support older versions. Here's a discussion about how to work around this pre-3.8 limitation of copytree: https://stackoverflow.com/questions/1868714/how-do-i-copy-an-entire-directory-of-files-into-an-existing-directory-using-pyth

Hi Mads

Would you like me to change the "%s" % variable format by f"{variable}" along the code? It would be more concise and readable code. I already did that while trying to change the use of os.path to make path to work on Windows, but Faust generated paths themselves aren't scaped or converted to that platform (and generated code don't check libraries availability and alternatives).

I'm not sure if this is me doing something wrong, but I can't get the generated class files to include the inputs to the faust process. The faust file below generates *ar/*kr-methods with only one argument, cutoff. The faust2supercollider script from the faust distribution prepends an in1 argument. What can be the problem here?

Faust file:

import("stdfaust.lib");
freq=vslider("cutoff",500,20.0,20000,1);
process= _: ve.wah4(freq) : _;

Generated class file:

Wah4 : UGen {
    *ar{|cutoff(500)| 
      ^this.multiNew('audio', cutoff)
    }

    *kr{|cutoff(500)|
      ^this.multiNew('control', cutoff)
    }
...
}
