Usage

Arguments

`x`	`⁠[tree_sitter_tree]⁠` A tree.

Value

A TreeCursor object.

Examples


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

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

cursor <- tree_walk(tree)

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