var Annotations = []Mapping{
	AnnotateType("internal-type", nil, role.Incomplete),
}

Annotations is a list of individual transformations to annotate a native AST with roles.

var Code = []CodeTransformer{
	positioner.FromOffset(),
}

Code is a special block of transformations that are applied at the end and can access original source code file. It can be used to improve or fix positional information.

var Native = Transformers([][]Transformer{

	{Mappings(Annotations...)},
	{

		RolesDedup(),
	},
}...)

Native is the of list `transformer.Transformer` to apply to a native AST. To learn more about the Transformers and the available ones take a look to: https://godoc.org/gopkg.in/bblfsh/sdk.v2/uast/transformer

var Normalize = Transformers([][]Transformer{

	{Mappings(Normalizers...)},
}...)

var Normalizers = []Mapping{}

Normalizers is the main block of normalization rules to convert native AST to semantic UAST.

var Preprocess = Transformers([][]Transformer{
	{

		ResponseMetadata{
			TopLevelIsRootNode: false,
		},
	},
	{Mappings(Preprocessors...)},
}...)

var PreprocessCode = []CodeTransformer{}

PreprocessCode is a preprocessor stage that can use the source code to fix tokens and positional information.

var Preprocessors = []Mapping{

	ObjectToNode{
		InternalTypeKey: "...",
	}.Mapping(),
}

Preprocessors is a block of AST preprocessing rules rules.
