Tree accessors

Description

• tree_text() retrieves the tree's text that it was parsed with.

• tree_language() retrieves the tree's language that it was parsed with.

• tree_included_ranges() retrieves the tree's included_ranges that were provided to parser_set_included_ranges(). Note that if no ranges were provided originally, then this still returns a default that always covers the entire document.

Usage

tree_included_ranges(x)

tree_text(x)

tree_language(x)

Arguments

x	⁠[tree_sitter_tree]⁠ A tree.

Value

• tree_text() returns a string.

• tree_language() returns a tree_sitter_language.

• tree_included_ranges() returns a list of range() objects.

Examples

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

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

tree_text(tree)
tree_language(tree)
tree_included_ranges(tree)
