writeAsPlist

Object method

object.writeAsPlist(path);

Write the object to disk as a PropertyList.  It is used commonly in OS X to store data.  

This is an XML format that may be read from easily from Objective-C, Java or any language that uses the CoreFoundation(Cocoa) framework.  

Objective-C:

id rootObject = [NSKeyedUnarchiver  unarchiveObjectWithFile: path ];

The file may be double-clicked to open it in Property List Editor.

When opening the PropertyList:

your SC objects are converted to Foundation objects in this fashion:

SimpleNumber -> NSNumber.

SequenceableCollections -> NSArray with each item converted

Strings -> NSString

Symbols -> NSString

Char -> NSString

Nil -> NSNull

Boolean ->NSNumber (numberWithBool:) equivalent to a CFBoolean

Dictionary ->NSDictionary (each item converted)

Other objects  -> NSNull

Most commonly the root object is an NSDictionary or NSArray.
