3 summary:: The concrete instance of Process
4 related:: Classes/StartUp
8 Main is the concrete instance of link::Classes/Process:: (the runtime environment for the virtual machine and interpreter).
9 Main overrides some methods of Process. There are two methods of interest. One is named startup and is
10 called after the class library has been compiled. The other is called shutdown which gets called when the library gets re-compiled.
13 The singleton instance of Main is available through the special keyword thisProcess.
14 For example, to find out what platform you're on:
17 thisProcess.platform; // --> e.g. "an OSXPlatform", "a LinuxPlatform", ...
22 subsection:: SuperCollider version
23 These class methods tell you which version of SuperCollider you are running and whether that version complies to your required minimum / maximum settings:
27 returns:: the current version as a human readable string
29 method::versionAtLeast
30 check if we are running at least version maj.min
32 Main.versionAtLeast( 3, 1 );
34 returns:: true or false
37 check if we are running version maj.min or older
39 Main.versionAtMost( 3, 1 );
41 returns:: true or false
45 private::prArgv, prOpenUDPPort
49 Called after the class library has been compiled.
52 This calls the superclass' startup, which among other things initializes the link::Classes/AppClock:: and the top-level link::Classes/Environment::.
54 Main's startup then stores Server.default in the interpreter variable s, sets the platform default's link::Classes/GUI:: kit, initializes the link::Classes/GeneralHID:: system, calls a link::Classes/Platform:: specific startup method (for example OSXPlatform's startup opens the server windows), and finally invokes StartUp.run.
56 To add your own startup functionalities, you could either edit the special startup-file (discussed in link::Reference/StartupFile::), or use StartUp.add as discussed in the link::Classes/StartUp:: help file.
60 Called after SuperCollider is quit or the class library is about to be re-compiled.
63 This will quit all audio link::Classes/Server:: instances, perform a platform specific shutdown (e.g. on Mac OS X, the HID service is released), finally Process' shutdown method is called, resulting successive calls to UI.shutdown, NetAddr.disconnectAll, File.closeAll, and Archive.write. To register your own shutdown code, use a call like this:
66 UI.registerForShutdown({ "Good bye!!".postln });
71 Override this to do whatever you want, e. g. add a class extension file like this to the class library:
75 run { "myPatch.rtf".load }
81 Get or set a custom link::Classes/Function:: in this field that gets called whenever SuperCollider language (the client) receives an OSC message.
83 warning::Generally speaking users should not use this setter, but instead should use link::#-addOSCFunc:: and link::#-removeOSCFunc:: to avoid overwriting any functions added by system objects.::
86 A link::Classes/Function:: or similar object to be set. When evaluated, this function will be passed the arguments time, replyAddr, recvPort, and message, corresponding to the time the message was sent, the link::Classes/NetAddr:: of the sender, the port on which the message was received, and the message itself as an link::Classes/Array::.
90 Register a link::Classes/Function:: to be evaluated whenever SuperCollider language (the client) receives an OSC message. This will not overwrite any previously registered functions.
93 A link::Classes/Function:: or similar object to be added. When evaluated, this function will be passed the arguments time, replyAddr, recvPort, and message, corresponding to the time the message was sent, the link::Classes/NetAddr:: of the sender, the port on which the message was received, and the message itself as an link::Classes/Array::.
96 // post all incoming traffic except the server status messages
97 // basically the same as OSCFunc.trace
99 f = { |time, replyAddr, recvPort, msg|
100 if(msg[0] != '/status.reply') {
101 "At time %s received message % from %\n".postf( time, msg, replyAddr, recvPort )
104 thisProcess.addOSCFunc(f);
108 thisProcess.removeOSCFunc(f);
111 method::removeOSCFunc
113 Remove a link::Classes/Function:: from the list of those evaluated whenever SuperCollider language (the client) receives an OSC message. This will leave any other registered functions in place.
116 A link::Classes/Function:: or similar object to be removed.
118 method::replaceOSCFunc
120 Replace a link::Classes/Function:: in the list of those evaluated whenever SuperCollider language (the client) receives an OSC message with a different one. This will leave any other registered functions in place.
123 The link::Classes/Function:: or similar object to be replaced.
126 A link::Classes/Function:: or similar object to be replace the one being removed. When evaluated, this function will be passed the arguments time, replyAddr, recvPort, and message, corresponding to the time the message was sent, the link::Classes/NetAddr:: of the sender, the port on which the message was received, and the message itself as an link::Classes/Array::.
129 Attempt to open a new UDP port for receiving OSC traffic. If another application has already bound to the requested port this will fail. Once opened, ports remain bound until SC is recompiled.
132 An link::Classes/Integer:: indicating the port to attempt to bind.
134 returns::A link::Classes/Boolean:: indicating whether the attempt was successful.
137 thisProcess.openUDPPort(3000); // will return true or false.
138 thisProcess.customPorts; // returns all working custom ports
142 Get a collection of all active custom UDP ports.
144 returns::An link::Classes/Array::.
148 Returns:: The operating system's pid (process ID) for the process.
150 method::preferencesAction
152 A function to evaluate when the SuperCollider preferences menu is selected.
155 thisProcess.preferencesAction = { arg process; SCWindow.new.front; }
160 Recompiles the class library. This is equivalent to restarting SC. Currently OSX (SuperCollider.app) only.
163 Get the current link::Classes/Platform::
166 Get the command-line arguments passed to sclang.
