Add compiler option to pass parameters to a Faust program through shell invocation #398

Open dariosanfilippo opened 4 years ago

dariosanfilippo commented 4 years ago

In many cases, I need to test my networks just by changing one single constant and see the results for different values of that variable. That implies that I open the Faust file, I edit it, I save it, and then I compile it.

Would it be possible to have a compiler option so that, similarly to Gnuplot 5 and its -c option, parameters can be passed to a Faust program through the shell?

This would be handy for the example that I described above, but it would also be useful when a Faust program is used as a program generator. In my specific case, I am planning on turning a software library of mine into a music software that is piloted through very few essential parameters to generate different standalone audio networks. Hence, it would be great if the user could generate different networks from the shell just by changing such parameters rather than editing a file, saving, and then compiling.

Thank you for your time.

Hi Dario,

Are you aware that you can set Faust GUI parameters on the command line? Example: https://ccrma.stanford.edu/~jos/aspf/Offline_Processing_Soundfiles_FAUST.html

Cheers,

Thanks, Julius. I wasn't aware of that.

But could you, for example, change the size of a Hadamard matrix?

Best, Dario

Two remarks here:

josmithiii commented 4 years ago

Yes, for hadamard matrices, I would compile all the sizes I wanted to try (only powers of 2), and switch among them at run time.

Is it straightforward to include some Faust architecture header file in your architecture file to give it options support?

Yes something like:

#include "faust/gui/console.h"

and this line in int main(int argc, char* argv[])

CMDUI interface(argc, argv, true);

Perfect!

That that would be a solution for small DSP processes, though I often need to change one parameter, say the feedback coefficient, of large networks, hence I wouldn't have enough CPU to switch among several.

I guess that what Stéphane suggests is an ad-hoc fix, though other users would be able to do the same without the modification.

Other than the ease of changing a parameter from the shell, it would make a Faust program more encapsulated following a black-box approach.

For example, using a Faust program to generate Kauffman's Boolean networks: the number of nodes and the topology is fixed, though the function in each node is selected randomly.

The user could enter a seed in the shell to trigger several pseudo-random generators in the .dsp code and flash a different network each time the seed changes.

Similarly to Gnuplot, something like this:

faust2caqt -double -parameter kauffman.dsp 0.0022993

The value after the .dsp would replace a special identifier inside the .dsp file, such as ARG1.

There is no mechanism right now to easily give compile time arguments to DSP programs. Have you tried the more dynamic approach using the embedded compiler as in faustgen~ either for PureData https://github.com/CICM/pd-faustgen or Max/MSP https://github.com/grame-cncm/faust/releases ?

dariosanfilippo commented 4 years ago

Hi, Stéphane. No, I haven't tried those.

I don't mind opening a file and saving it but, as I said, it would be great if you could separate the user from editing the file completely so that a Faust program can be an autonomous environment used by the user to generate a set of programs.

Please take this feature into account for future developments if you all think is feasible and useful.

Thanks for your time, Dario
