RE: GNUStep parsing OSX binary plist changed?

[L Zee]

Hi,

Thanks for responding and clarifying it is printing the class of the object. I am expecting the object to be a NSDicrionary object.
I have attached the History.plist file, and additional info on the the results using this file.


The below code on Linux w/GNUStep (native Ubuntu 9.04)
$>md5sum ~/Desktop/History.plist
656ce0c8705d8c38b95a22356b6cfd9a

$> ./test ~/Desktop/History.plist

2010-01-29 13:15:26.594 safari_hist[3276] WebHistoryFileVersion
2010-01-29 13:15:26.604 safari_hist[3276] Detected format as GSCBufferString
Aborted


The same code (below) on OSX with the same History.plist file

maccy$ md5 ~Desktop/History.plist
MD5 (History.plist) = 656ce0c8705d8c38b95a22356b6cfd9a

maccy$ ./test ~/Desktop/History.plist
2010-01-29 13:17:30.132 test[1019] {
    WebHistoryDates = (
        {
            "" = "http://www.apple.com/startpage/";
            D = (2);
            lastVisitedDate = "286477969.8";
            title = "Apple - Start";
            visitCount = 2;
        }
    );
    WebHistoryFileVersion = 1;
}
2010-01-29 13:17:30.133 test[1019] Detected format as NSCFDictionary
2010-01-29 13:17:30.133 test[1019] 1

Thanks for your help.
