Thanks for the quick reply!
Let's say i want to produce this patch:
#N canvas 404 128 765 600 10;
#X obj 10 10 osc~ 440;
#X obj 10 40 dac~;
#X connect 0 0 1 0;
#X connect 0 0 1 1;
I save somewhere an empty.pd containing only:
#N canvas 404 128 765 600 10;
I load it using:
libpd_openfile("empty.pd", ".");
Then I call something like:
libpd_symbol( "pd-empty.pd", ";\nobj 10 10 osc~ 440" );
libpd_symbol( "pd-empty.pd", ";\nobj 10 40 dac~;" );
// definition of libpd_symbol in z_libpd.h
// EXTERN int libpd_symbol(const char *recv, const char *sym);
And so on?

You probably can't build up a patch from nothing at all, but at least you can
add objects to an empty canvas - read the canvas from a file (say, "x.pd")
and send messages to "pd-x.pd" to add objects to it, connect them, etc.

Hello to all,
I'm currently bridging puredata and ogre3d via libpd. The whole project is a
game engine called polymorph (http://polymorph.cool)
I have a question regarding patch generation.
I can't find a way to send a patch to pd through a buffer. The only method i
found "libpd_openfile" but that requires creating an actual file on the
harddrive and passing the path to pd. I would need something like
"libpd_newpatch(char*)"...
The idea is to be able to build a patch programmatically, on the c++ side,
and send it to pd without saving it as a file.
Did anyone ever done something like that?
Thank in advance!
