var Annotations []Mapping

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

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/github.com/bblfsh/sdk/v3/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{
	{Mappings(Preprocessors...)},
}...)

var PreprocessCode = []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 Preprocessors = []Mapping{

	ObjectToNode{
		InternalTypeKey: "kind",
		OffsetKey:       "pos",
		EndOffsetKey:    "end",
		LineKey:         "line",
		ColumnKey:       "col",
	}.Mapping(),
}

Preprocessors is a block of AST preprocessing rules rules.

var Transforms = driver.Transforms{
	Namespace:      "typescript",
	Preprocess:     Preprocess,
	PreprocessCode: PreprocessCode,
	Normalize:      Normalize,
	Annotations:    Native,
