Adobe ExtendScript debugging

There's a dearth of info in the supporting PDFs and on the web. I happened to come across a post in a blog that ment开发者_如何学运维ioned that $.write() or $.writeln() will write a string to the javascript console. Quite useful. Does anyone know if this $ object has any additional properties or methods?

I just answered my own question. JavaScript Tools Guide CS4.pdf. Chapter 8 ExtendScript Tools and Features has all I need. Just getting started with Adobe scripting and I'm a bit overwhelmed with the huge array of elements in a CS4 install.

Bits of Photoshop are implemented in ExtendScript. If you look in the folder

[apps folder]/Adobe Photoshop CS4/Presets/Scripts/

You'll find several scripts that may be useful as sample code.
