Working on AppleScriptabilty of my Colloquy and ChatCore project I was in dire need of a way to take an object specifier AEDesc and resolve it. AEResolve didn’t help, as it only works with applications that have dozens of assessors installed, not based on key-value coding.

I needed a way to pass object specifiers to an AppleScript subroutine and get object specifiers from a script’s result.

After hours of painful searches I found nothing helpful. Time for class-dump I said.

Doing a dump of the Foundation framework (class-dump -s -C NSScriptObjectSpecifier /System/Library/Frameworks/Foundation.framework/Foundation), I found my answer!

@interface NSScriptObjectSpecifier (NSPrivate)

A quick test on my script proved my joyous find. I don’t know what inCommandConstructionContext is, and passing nil to it worked.

This really needs to be public, methinks. �TimothyHatcher

As of Leopard it is public: +[NSScriptObjectSpecifier objectSpecifierWithDescriptor:] and -[NSScriptObjectSpecifier descriptor]. Slowly, slowly, Apple exposes to us the APIs they know are needed to write working code… :) —WimLewis
