How to move a symlink to the trash? - cocoa

Question

I don't see any options for the FSPathMoveObjectToTrashSync() function for not following links.
Here is what I have tried
Create a link and a file
[ 21:32:41 /tmp ] $ touch my_file
[ 21:32:45 /tmp ] $ ln -s my_file my_link
[ 21:32:52 /tmp ] $ la
total 8
drwxrwxrwt 12 root wheel 408 17 Maj 21:32 .
drwxr-xr-x# 6 root wheel 204 9 Sep 2009 ..
-rw-r--r-- 1 neoneye wheel 0 17 Maj 21:32 my_file
lrwxr-xr-x 1 neoneye wheel 7 17 Maj 21:32 my_link -> my_file
Move the link to the trash
OSStatus status = FSPathMoveObjectToTrashSync(
"/tmp/my_link",
NULL,
kFSFileOperationDefaultOptions
);
NSLog(#"status: %i", (int)status);
Output is
status: 0
However the file got removed and not the link
[ 21:32:55 /tmp ] $ la
total 8
drwxrwxrwt 11 root wheel 374 17 Maj 21:33 .
drwxr-xr-x# 6 root wheel 204 9 Sep 2009 ..
lrwxr-xr-x 1 neoneye wheel 7 17 Maj 21:32 my_link -> my_file
[ 21:33:05 /tmp ] $
How can I move move symlinks to the trash?
The Solution.. thanks to Rob Napier
NSString* path = #"/tmp/my_link";
OSStatus status = 0;
FSRef ref;
status = FSPathMakeRefWithOptions(
(const UInt8 *)[path fileSystemRepresentation],
kFSPathMakeRefDoNotFollowLeafSymlink,
&ref,
NULL
);
NSAssert((status == 0), #"failed to make FSRef");
status = FSMoveObjectToTrashSync(
&ref,
NULL,
kFSFileOperationDefaultOptions
);
NSLog(#"status: %i", (int)status);

Answer 1

Use FSPathMakeRefWithOptions() to generate an FSRef to the link. Then use FSMoveObjectToTrashSync() to delete it.

Answer 2

The other way would be to tell the NSWorkspace to “recycle” it, by sending it either a performFileOperation:source:destination:files:tag: message with the NSWorkspaceRecycleOperation operation or a recycleURLs:completionHandler: message.
I don't know how well either one of these would work on symlinks, but it's worth trying if you'd rather not deal with FSRefs.

Answer 3

my retro-futuristic approach
https://github.com/reklis/recycle
//
// main.swift
// recycle
//
// usage: recycle <files or directories to throw out>
//
import Foundation
import AppKit
var args = NSProcessInfo.processInfo().arguments
args.removeAtIndex(0) // first item in list is the program itself
var w = NSWorkspace.sharedWorkspace()
var fm = NSFileManager.defaultManager()
for arg in args {
let path = arg.stringByStandardizingPath;
let file = path.lastPathComponent
let source = path.stringByDeletingLastPathComponent
w.performFileOperation(NSWorkspaceRecycleOperation,
source:source,
destination: "",
files: [file],
tag: nil)
}
