There are lots of options. The existing logging facility (in the File
menu) writes to a file with an arbitrary name, and can be configured
to write arbitrary properties at an arbitrary. You can make this file
a named pipe or a socket if you want to receive it by another process.
If you want it on stdout, you can use a really simple Nasal script
like this one (colon separated, with a terminal colon on the line
because I'm lazy):
outputProperties = ["/orientation/pitch-deg", ... ];
dumpOutput = func {
msg = "";
foreach(prop; outputProperties) {
msg = msg ~ getprop(outputProperties) ~ ":";
}
print(msg);
settimer(dumpOutput, 0.1); # Schedule to run again
}
settimer(dumpOutput, 0.1); # Schedule to the first time
There's also a TCP property interface about which I don't know as
much, which can be accessed by an external script which could poll at
whatever frequency you want.
