Have you looked at OSAKit? It has methods for executing subroutines of
scripts without having to do that "initWithSource" hack.
You can find the header files here: "/System/Library/Frameworks/
OSAKit.framework/Versions/A/Headers/"
A couple of caveats about using it though. Subroutine names have to be
all lowercase when you call them and parameters you feed to the script
MUST be enclosed in an NSArray, even if your script only takes one
parameter. So, for example if the subroutine name in the script is
"DoSomethineNifty" you have to call it as "dosomethingnifty"
Here's a sampling of what you'll find in the OSAKit->script header
file (Note the "executeHandlerWithName" method)
// Construction
- (id)initWithSource:(NSString *)source;
- (id)initWithSource:(NSString *)source language:(OSALanguage
*)language;
- (id)initWithContentsOfURL:(NSURL *)url error:(NSDictionary
**)errorInfo;
- (id)initWithContentsOfURL:(NSURL *)url language:(OSALanguage
*)language error:(NSDictionary **)errorInfo;
- (id)initWithCompiledData:(NSData *)data error:(NSDictionary
**)errorInfo;
// Accessors
- (NSString *)source;
- (NSURL *)url;
- (OSALanguage *)language;
- (void)setLanguage:(OSALanguage *)language;
- (BOOL)isCompiled;
// Operations
- (BOOL)compileAndReturnError:(NSDictionary **)errorInfo;
- (NSAppleEventDescriptor *)executeAndReturnError:(NSDictionary
**)errorInfo;
- (NSAppleEventDescriptor *)executeAppleEvent:(NSAppleEventDescriptor
*)event error:(NSDictionary **)errorInfo;
- (NSAppleEventDescriptor *)executeAndReturnDisplayValue:
(NSAttributedString **)displayValue error:(NSDictionary **)errorInfo;
- (NSAppleEventDescriptor *)executeHandlerWithName:(NSString *)name
arguments:(NSArray *)arguments error:(NSDictionary **)errorInfo;
- (NSAttributedString *)richTextSource;
- (NSAttributedString *)richTextFromDescriptor:(NSAppleEventDescriptor
*)descriptor;
- (BOOL)writeToURL:(NSURL *)url ofType:(NSString *)type error:
(NSDictionary **)errorInfo;
- (BOOL)writeToURL:(NSURL *)url ofType:(NSString *)type
usingStorageOptions:(OSAStorageOptions)storageOptions error:
(NSDictionary **)errorInfo;
- (NSData *)compiledDataForType:(NSString *)type usingStorageOptions:
(OSAStorageOptions)storageOptions error:(NSDictionary **)errorInfo;
Also, Have you looked into AppleScript Studio? You can call built-in
and custom Cocoa classes directly from your scripts which might be
useful if you just need to use Cocoa classes in certain spots to speed
things up.
For example:
To load an NSDictionary:
set dict to call method "dictionaryWithContentsOfFile:" of class
"NSDictionary" with parameter "/path/to/a/plist/file"
set x to (|some key| of dict) as string -- as list -- as record
log x
log dict
To split a string at a delimiter
set testString to "Homer says Doh!"
set parts to call method "componentsSeparatedByString:" of testString
with parameter " "
log parts

We have a lot of code in libraries in Applescript. Now starting to
look at using Cocoa to move forward, as we are really using
Applescript to pretty much its limit.
But it is not a short term solution to rewrite all our Applescript
libraries in Objective-C. We need to be able to use Objective-C
programs to load and execute our Applescripts.
I've managed to get a program to execute an Applescript and to
execute a handler in an Applescript.
But most of our libraries are saved as Script Objects. Please could
someone point me in the right direction for executing a subroutine
inside a script object in an Applescript.
I'm guessing I could do something like:
NSApplescript *scriptObject = [[NSAppleScript alloc]
initWithSource: @"set scriptObject to (scriptObjectName of (load
script file scriptPath))
tell scriptObject to doHandler()"];
and execute it, but that seems to be quite klunky. There must be a
neater way to do it.
Any advice, hints and links will be gratefully received.
Thank you
Karen
