Hi
I've been trying off and on for a couple of days to run a script that
requires parameters. The first problem I found was that NSAppleScript
has a bug that wipes out QuarkXPress's event dictionary when loading
scripts containing Quark commands. Someone pointed me to the OSAScript
framework which doesn't have this bug, but I'm getting -1708
(errAEEventNotHandled) errors.
My code is running as a Quark XTension so I may be setting up the
"targetAddress" incorrectly. Could someone take a look at the
following snippet and point out where I'm messing up?
Thanks in advance
Here's what the NSLogs print to the console
> targetAddress: <NSAppleEventDescriptor: 'kpid'("QuarkXPress")>
> event: <NSAppleEventDescriptor: 'ascr'\'snam'{ '----':
[ 'utxt'("Thursday, November 20, 2008") ] }>
> subroutineDescriptor: <NSAppleEventDescriptor:
'utxt'("replacefoliodates")>
> argsDescriptor: <NSAppleEventDescriptor: [ 'utxt'("Thursday,
November 20, 2008") ]>
> result: (null)
> error: {
OSAScriptErrorNumber = -1708;
} running script: AA_01-05
And here's the code:
Note: the "aeDescriptor" method in the line [inArguments aeDescriptor]
is a category that coerces common types like NSArray, NSDictionaries,
NSNumbers etc... into AEDescriptors.
// NOTE this method is a category on OSAScript
- (NSAppleEventDescriptor *) executeHandler: (NSString *) inHandler
withArguments: (id) inArguments
errorInfo: (NSDictionary **) inErrorInfo
{
int pid
= [[NSProcessInfo processInfo]
processIdentifier];
NSAppleEventDescriptor *targetAddress = [[NSAppleEventDescriptor
alloc] initWithDescriptorType: typeKernelProcessID
bytes: &pid
length: sizeof(pid)];
NSAppleEventDescriptor *event = [[NSAppleEventDescriptor alloc]
initWithEventClass: typeAppleScript
eventID: keyASSubroutineName
targetDescriptor: targetAddress
returnID: kAutoGenerateReturnID
transactionID:
kAnyTransactionID],
*subroutineDescriptor = [NSAppleEventDescriptor
descriptorWithString: [inHandler lowercaseString]],
*argsDescriptor
= [inArguments aeDescriptor];
NSAppleEventDescriptor *result;
NSLog(@"------------- targetAddress: %@", targetAddress);
NSLog(@"------------- event: %@", event);
NSLog(@"------------- subroutineDescriptor: %@", subroutineDescriptor);
NSLog(@"------------- argsDescriptor: %@", argsDescriptor);
// Set up an AppleEvent descriptor containing the subroutine
(handler) name
[event setParamDescriptor: subroutineDescriptor forKeyword: 'snam'];
// Add the provided arguments to the handler call
[event setParamDescriptor: argsDescriptor forKeyword: keyDirectObject];
// Execute the handler
result = [self executeAppleEvent: event error: inErrorInfo];
[targetAddress release];
[event release];
NSLog(@"------------- result: %@", result);
return result;
}
