[sc-users] fifos

[Till Bovermann]

Hey list,

still on this python-accessing problem... (thanx to all helping hands)

why doesn't this work?
any help appreciated

-------------- code -----------------

q = ();
q.path = "/tmp/";
q.sclang2AppName = "%/fifo_SC2App_%".format(q.path, this.hash);
q.fifos = [];

(
q.addFifo = {|fifoPath|
	("mkfifo -m 700 %").format(fifoPath).systemCmd;
	//"echo hahahaha >> %".format(fifoPath).systemCmd;
	q.fifos = q.fifos ++ [fifoPath];
};
q.openFifoForRead = {|fifoPath|
  	q.in = File(fifoPath, "r").open
};
q.read = {
	var line, result = "";
	line = q.in.getLine;
	while({line.notNil}, {
		result = result + line;
		line = q.in.getLine;
	});
	result;
};
q.write = {|str|
  		q.out.write(str); q.out.flush;
};
q.closeFifoForRead = {|fifoPath|
  	q.in.close
};
q.cleanUp = {
	q.fifos.do{|path|  "rm %".format(path).systemCmd };
	q.fifos = [];
};
)

q[\addFifo].value(q.sclang2AppName)
q.in = q[\openFifoForRead].value(q.sclang2AppName)
//  echo "hahahah" >> fifo_SC2App_<hasValue> will help to get sc out  
of hybernation
