Description

node_walk() creates a TreeCursor starting at the current node. You can use it to "walk" the tree more efficiently than using node_child() and other similar node functions.

Usage

node_walk(x)

Arguments

x	⁠[tree_sitter_node]⁠ A node.

Value

A TreeCursor object.

Examples

language <- treesitter.r::language()
parser <- parser(language)

text <- "1 + foo"
tree <- parser_parse(parser, text)
node <- tree_root_node(tree)

cursor <- node_walk(node)

cursor$goto_first_child()
cursor$goto_first_child()
cursor$node()
cursor$goto_next_sibling()
cursor$node()
