I would like to add a new item to the Finder sidebar. I found out that the Finder keeps the list of \"places\" in `~/Library/Preferences/com.apple.sidebarlists.plist. I was

Take a look here:

The Shared File List API is new to Launch Services in Mac OS X Leopard. This API provides access to several kinds of system-global and per-user persistent lists of file system objects, such as recent documents and applications, favorites, and login items. For details, see the new interface file LSSharedFileList.h.

You want to look for the key kLSSharedFileListFavoriteItems, which handles the items under "Places" in the Sidebar. I guess you could try to do something similar to this, using LSSharedFileListCreate to create kLSSharedFileListFavoriteItems.

Or you could use the applescript posted here, which would be way easier, but not the "Right Way"©

@Asmus : By default 'command + T' is the shortcut to add a folder to sidebar in finder. Applescript pointed by u is working fine when keyboard shortcut key 'command + T' is assigned manually to other tasks.

The applescript fails if executed after setting 'command + T' as the shortcut key to show my other desktop in osx lion(10.7)

Update for 2015

The LSSharedFileList header says this has moved to the CoreServices framework. In fact, if you Cmd-Shift-O (in Xcode) and type LSSharedFileList, then navigate to the only result, you'll see in the jump bar that the header is indeed now contained within CoreServices.framework. In any case, the key is still kLSSharedFileListFavoriteItems.

Example:

+ (BOOL)appendFavoriteItemWithURL:(NSURL *)url {

  // Pessimism ...
  BOOL result = NO;

  // Do we have a file URL?
  if (url.isFileURL) {

    // Ask CoreServices for the favorite items list 
    // (kLSSharedFileListFavoriteItems)
    LSSharedFileListRef list = LSSharedFileListCreate(NULL, kLSSharedFileListFavoriteItems, NULL);
    if (list) {

      // We've got the list, so try to append our item
      // (use kLSSharedFileListItemBeforeFirst vs. 
      // kLSSharedFileListItemLast if desired)
      LSSharedFileListItemRef item = LSSharedFileListInsertItemURL(list,
                                     kLSSharedFileListItemLast,
                                     NULL,
                                     NULL,
                                     (__bridge CFURLRef)url,
                                     NULL,
                                     NULL);

      // Did it work?
      if (item) {

        // Release the item and flag success
        CFRelease(item);
        result = YES;

      }

      // Release the list
      CFRelease(list);

    }

  }

  return result;
}

Usage:

// Create the path to the favorite item to add
NSString * itemPath = [@"~/Music" stringByExpandingTildeInPath];
NSURL * itemURL = [NSURL fileURLWithPath:itemPath];

// Insert the item
[WhateverClassTheAboveFunctionIsIn appendFavoriteItemWithURL:itemURL];
