hi everybody,

i want to find out about the favorites someone set. neither nsuserdefaults nor nsfilemanager nor nsworkspace offer me a simple list of favorites.

so i thought that it might be in some .plist. doesn't seem to be.

then i thought that i'd just resolve the aliases in ~/library/favorites.

the question is: how do i resolve aliases? resolving symlinks is easily done with nsfilewrapper, but aliases?

i have an idea for a workaround, but i'm not sure it'll work and also it would be very ugly.

any ideas?

edit: i'm aware of the carbon alias manager. don't tell me there's no way to do that from cocoa.

You are welcome to use this method I wrote (as a category on NSString). It's from my JPEGDeux program. Make sure to #import <Carbon/Carbon.h> as well.

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>

<font color = brown>//returns a path to the file pointed at by self if self is an alias, self otherwise</font>
<font color = brown>//yes, we do follow chains of aliases</font>
<font color = brown>//returns nil if self cannot be resolved. Does not attempt to mount volumes.</font>
<font color = brown>//if isDir is not nil, returns whether or not the resolved file is a directory</font>
- (NSString*)resolveAliasesIsDir BOOL*)pIsDir {
Boolean isDir, wasAlias;
FSRef ref;
OSStatus result;
result=FSPathMakeRef([self UTF8String], &ref, &isDir);
if (result != noErr) return nil;
if (isDir) {
if (pIsDir) *pIsDir=YES;
return self;
}
result=FSResolveAliasFileWithMountFlags(&ref, YES, &isDir, &wasAlias, kARMNoUI | kARMSearch);
if (pIsDir) *pIsDir=isDir;
if (result != noErr) return nil;
if (wasAlias) {
unsigned char pathBuff[<font color = blue>512</font>];
result=FSRefMakePath(&ref, pathBuff, sizeof pathBuff);
if (result != noErr) return nil;
return [NSString stringWithCString athBuff];
}
return self;
}

</font>[/code]

Beware: while looking back over my code, I think it may have issues with aliases that refer to files with non-ASCII characters in their names.

Oh, to answer your second question, there's no way to do it from Cocoa. Yet.

carbon really is something i haven't yet discovered, but i'll see what i can make of it.

your help is really appreciated, thank you very much!
