Well I think it would be of great benefit to Pd if we all stopped doing it in
our own once off, implementation specific, half-arsed way and did it properly
and robustly and submitted the code back to Miller. I already submitted some
half-arsed code for this to him (see the attached patch against Makefile.in),
but I think my chances aren't that great for getting it accepted, since it
stinks! :)
Damien, if you want you can try with that patch and something like this:
void* launchpd(void* arg)
{
char* args[2] = {"pd", "-nogui"};
sys_printhook = (t_printhook)my_printhook;
sys_main(2, args);
}
I think a lot of people dream of a libpd which is independent of all the GUI
code and the driver-specific audio code. It would be awesome if I could go:
t_pd* mypd = launchpd();
while (1) {
mypd->getBuffer(mybuffer);
}
It would certainly make it easier to make stuff like browser plugins. I dream
of a day when we post the libpd code to the whatwg list and it gets accepted by
all the major browsers, and then we have in-browser procedural audio for our
web apps.
Chris.
