A Script that Rules the World

2010-11-21 01:26:17 supercollider

clean-up #6:

This is a hack from 2007. It was done in CocoaCollider, but now I updated it using the standard SCNSObject in SuperCollider. It works by talking to Google Earth via AppleScript.

Some notes:

There are two ways to run AppleScripts from within SuperCollider. One is to construct a string with osascript -e and a unixCmd, the other is creating a cocoa NSAppleScript object with the SCNSObject cocoa binding class. The later method is slightly more involved but runs way faster.

//--unixCmd version
"osascript -e 'tell application \"Finder\" to activate'".unixCmd;
"osascript -e 'tell application \"TextEdit\" to activate'".unixCmd;
//--NSObject version - this only work on old OSX SuperCollider versions
a= SCNSObject("NSAppleScript", "initWithSource:", ["tell application \"Finder\" to activate"]);
a.invoke("executeAndReturnError:", [nil], true);
a.release;

SCNSObject.dumpPool;  //should be 0
SCNSObject.freePool;  //free stray objects if any left

Also, I've attached a simple class that wraps the functionality. It's called RedEarth.
