Any idea what i'm doing wrong?
You're using an alias file; that's what you're doing wrong. As I
said, only Carbon and certain AppKit classes resolve aliases. BASH
doesn't use Carbon or AppKit; it uses lower level stuff that
doesn't resolve aliases. You'll have to use links (hard or
symbolic) instead.
From the looks of it, it doesn't sound like she's trying to use an
alias in bash; more likely, she's trying to create an alias file
that she would double-click in the Finder, but she's doing it
incorrectly in such a manner that LaunchServices is guessing that
the file is an executable and thus trying to open it with the
Terminal.
Thats exactly what i'm trying to accomplish, and bye the way i am
"he" :)
Whoops, my apologies.
I think this code should do what you want:
- (BOOL)makeAliasFile:(NSString *)destPath originalFile:(NSString
*)originalPath {
NSMutableString *source = [NSMutableString
stringWithString:@"tell application \"Finder\"\n"];
[source appendFormat:@"set theAlias to make alias at POSIX file
\"%@\" to POSIX file \"%@\"\n", NSTemporaryDirectory(), originalPath];
[source appendFormat:@"get POSIX path of (theAlias as string)\n"];
[source appendFormat:@"end tell"];
NSAppleScript *script = [[[NSAppleScript alloc]
initWithSource:source] autorelease];
NSDictionary *error = nil;
NSAppleEventDescriptor *desc = [script
executeAndReturnError:&error];
if(desc == nil) {
return NO;
} else {
return [[NSFileManager defaultManager] movePath:[desc
stringValue] toPath:destPath handler:nil];
}
}
It would also be possible to use the resource-fork method described
earlier in this thread, but the method above is probably the method
that is least likely to break (for example, if Apple ends up switching
to a new file system that uses something other than the resource fork
to store its aliases, then building them yourself in that fashion
could conceivably stop working).
HTH,
Charles
