OSCresponderNode client side network responder

Register a function to be called upon receiving a specific command from a specific OSC address.

same interface like OSCresponder, but allows multiple responders to the same command.

Note that OSCresponderNode evaluates its function in the system process.

In order to access the application process (e.g. for GUI access ) use { ... }.defer;

Other applications sending messages to SuperCollider should distinguish between sending messages to the server or the language. Server messages are documented in the Server-Command-Reference and should be sent to the server's port - s.addr.port - which is 57110 by default. Messages sent to the server will not be processed by any OSCresponder in the language.

Messages from external clients that should be processed by OSCresponders must be sent to the language port, 57120 by default. Use NetAddr.langPort to confirm which port the SuperCollider language is listening on.

See OSC_communication for more details.

Setting up OSCresponder for listening to a remote application

// example: two SuperCollider apps communicating

// application 1:

n = NetAddr("127.0.0.1", 57120); // the url should be the one of computer of app 2 (or nil)

o = OSCresponder(n, '/chat', { |t, r, msg| ("time:" + t).postln; msg[1].postln }).add;

// application 2:

m = NetAddr("127.0.0.1", 57120); // the url should be the one of computer of app 1

m.sendMsg("/chat", "Hello App 1");

// sending bundles (including timestamps)

(

m.sendBundle(2.0, ["/chat", "Hello App 1"], ["/chat", "Hallo Wurld"]);

m.sendBundle(0.0, ["/chat", "Hello App 1"], ["/chat", "Hallo Wurld"]);

)

// end application 2:

m.disconnect;

// end application 1:

n.disconnect; o.remove;

Sending data from server to client

// example from SendTrig

(

s = Server.local;

s.boot;

s.notify;

)

(

SynthDef("help-SendTrig",{

SendTrig.kr(Dust.kr(1.0), 0, 0.9);

}).send(s);

// register to receive this message

a = OSCresponderNode(s.addr, '/tr', { arg time, responder, msg;

[time, responder, msg].postln;

}).add;

b = OSCresponderNode(s.addr, '/tr', { arg time, responder, msg;

"this is another call".postln;

}).add;

)

x = Synth.new("help-SendTrig");

a.remove;

b.remove;

x.free;

Watching for something specific

// end of group message

s.boot;

a = OSCresponderNode(s.addr,'/n_end',{ arg time,responder,msg;

[time, responder, msg].postln;

if(msg[1] == g.nodeID,{

"g is dead !".postln;

// g = Group.new;

});

}).add;

g = Group.new;

g.free;

a.remove;

Watching for errors

// example from ServerErrorGui in crucial lib

f = OSCresponderNode(s.addr, '/fail', { arg time, responder, msg;

{

var mins,secs;

mins = (time/60).round(1);

secs = (time%60).round(0.1);

if(secs<10,{ secs = "0"++secs.asString; },{ secs=secs.asString;});

// put this on a gui

//errors.label = "% % (%:%)".format(msg[1], msg[2], mins, secs);

//errors.stringColor = Color.white;

"% % (%:%)".format(msg[1], msg[2], mins, secs).postln;

}.defer

});

f.add;

// cause a failure

Synth("gthhhhppppppp!");

f.remove
