YAML.framework for Objective-C

Based on C LibYAML library (http://pyyaml.org/wiki/LibYAML) by Kirill Simonov.

YAML.framework provides support for YAML (de/)serialisation similarly to standard NSPropertyListSerialization.

It's fast and compatible with iOS.

Example usage

NSInputStream *stream = [[NSInputStream alloc] initWithFileAtPath: @"yaml/items.yaml"];
// or [[NSInputStream alloc] initWithURL: ...]

// You can use objectsWithYAMLStream:options:error instead to get all YAML documents.
//
// Alternativelly object(s)WithYAMLData:options:error or object(s)WithYAMLString:options:error.
id yaml = [YAMLSerialization objectWithYAMLStream: stream
                                          options: kYAMLReadOptionStringScalars
                                            error: nil];

// Dump Objective-C object description.
printf("%s", [[yaml description] UTF8String]);

For input YAML file:

items:
  - name: Foo
  - name: Bar

Should print dump string similar to:

(
  {
    items = (
      {
        name = Foo;
      },
      {
        name = Bar;
      }
    );
  }
)

API

The following class methods are defined on YAMLSerialization class.

Reading YAML

// Returns all document objects from parsed YAML stream.
+ (NSMutableArray *) objectsWithYAMLStream: (NSInputStream *) stream
                                   options: (YAMLReadOptions) opt
                                     error: (NSError **) error;

// Returns all document objects from parsed YAML data.
+ (NSMutableArray *) objectsWithYAMLData: (NSData *) data
                                 options: (YAMLReadOptions) opt
                                   error: (NSError **) error;

// Returns all document objects from parsed YAML string.
+ (NSMutableArray *) objectsWithYAMLString: (NSString *) string
                                   options: (YAMLReadOptions) opt
                                     error: (NSError **) error;

// Returns first object from parsed YAML stream.
+ (id) objectWithYAMLStream: (NSInputStream *) stream
                    options: (YAMLReadOptions) opt
                      error: (NSError **) error;

// Returns first object from parsed YAML data.
+ (id) objectWithYAMLData: (NSData *) data
                  options: (YAMLReadOptions) opt
                    error: (NSError **) error;

// Returns first object from parsed YAML string.
+ (id) objectWithYAMLString: (NSString *) string
                    options: (YAMLReadOptions) opt
                      error: (NSError **) error;

Writing YAML

// Returns YES on success, NO otherwise.
+ (BOOL) writeObject: (id) object
        toYAMLStream: (NSOutputStream *) stream
             options: (YAMLWriteOptions) opt
               error: (NSError **) error;

// Caller is responsible for releasing returned object.
+ (NSData *) createYAMLDataWithObject: (id) object
                              options: (YAMLWriteOptions) opt
                                error: (NSError **) error NS_RETURNS_RETAINED;

// Returns autoreleased object.
+ (NSData *) YAMLDataWithObject: (id) object
                        options: (YAMLWriteOptions) opt
                          error: (NSError **) error;

// Caller is responsible for releasing returned object.
+ (NSString *) createYAMLStringWithObject: (id) object
                                  options: (YAMLWriteOptions) opt
                                    error: (NSError **) error NS_RETURNS_RETAINED;

// Returns autoreleased object.
+ (NSString *) YAMLStringWithObject: (id) object
                            options: (YAMLWriteOptions) opt
                              error: (NSError **) error;
