Functions

func Rewrite

func Rewrite(n syntax.Node, f func(syntax.Node) NodeAction) syntax.Node

Rewrite traverses a syntax tree in depth-first order. It starts by calling f(n); n must not be nil. f then returns whether to Rewrite itself recursively or to replace n. Rewrite then calls f(nil).

Types

type NodeAction

type NodeAction struct {
	Recurse   bool
	Replace   bool
	ReplaceBy syntax.Node
}
