export a .swf from the command line

using Flash MX 2004's new JSFL authoring-tool scripting language, you can now export a .swf file directly from the command line. unfortunately, the authoring tool will launch to do the export, but you can quit it automatically once it's done. here's a quickie code sample to show how it works:

Code in exportPetSupplies.jsfl:
// Open the .fla file.
var doc = fl.openDocument("file:///c|/data/projects/pet/petsupplies.fla");
// Export the .swf file.
doc.exportSWF("file:///c|/data/projects/pet/petsupplies.swf", true);
// Quit the Flash MX 2004 authoring tool (optional).

Command issued on command-line from /pet/ directory:
"c:\program files\macromedia\flash mx 2004\flash.exe" exportPetSupplies.jsfl

now that's darn cool. it lets you add .swf compilation into a build tool like Apache Ant. sweet.

For Mac users can you translate for a unix terminal?

nice...BUT, it takes a while for the authoring tool to open...

how about specifying the swf and fla from commandline also? and put all of it in a batch file to get rid of the jsfl call

Does not seem to work if MX04 is already open but if it is closed works like a charm. Getting closer to Generator every day.
