If you don't need PD for anything else you maybe use something lighter.
See https://stackoverflow.com/questions/28137559/can-someone-explain-wavwave-file-headers to know your file header size, replace 44 below if needed.
hexdump --skip 44 --no-squeezing --format '2/2 "%3d "' 'file.wav' show decimal signed int

Some file format description if someone need it:

Hi,
combine the message first

Hi,

sudo apt install gem

do the stuff.

Hi,
next step is learning abstractions and [send] and [receive] usage.

Here is your path unknotted.

@whale-av Thank you.
I think the GUI has to be created once and saved, it doesn't need dynamic patching. That's why I like python.

Doesn't exist a python module to parse pd files ?

Hi,
does anybody know a solution to auto generate an on-parent-gui for abstractions ?

My first idea is to python-parse the pd file to find the nearest comment for each in/outlets in order to create the gui.

How can I show creation arguments in the canvas label ?
Another question is the icon integration : which object to use ? how to deal with size and placement ?

You can implement a loopback to choose a new number if nothing is sent.

NB : this example stack-overflows if nothing is open.

@jumeca You can send "open fileName dirName" to pd
