Method Query

tree.go:374–380

Query executes a tree-sitter query on a specific Node. Nodes captured by the query are passed one at a time to the provided callback function. See https://tree-sitter.github.io/tree-sitter/using-parsers#pattern-matching-with-queries for query syntax documentation.

(query string, fn func(*Node))

// See https://tree-sitter.github.io/tree-sitter/using-parsers#pattern-matching-with-queries
// for query syntax documentation.
func (n *Node) Query(query string, fn func(*Node)) {
	n.QueryMulti(query, func(qr QueryResult) {
		for _, n := range qr {
			fn(n)
		}
	})
}

// QueryResult is a map of capture names to the corresponding nodes that they matched
type QueryResult map[string]*Node
