Parser adjustments

Description

• parser_set_language() sets the language of the parser. This is usually done by parser() though.

• parser_set_timeout() sets an optional timeout used when calling parser_parse() or parser_reparse(). If the timeout is hit, an error occurs.

• parser_set_included_ranges() sets an optional list of ranges that are the only locations considered when parsing. The ranges are created by range().

Usage

parser_set_language(x, language)

parser_set_timeout(x, timeout)

parser_set_included_ranges(x, included_ranges)

Arguments

x

⁠[tree_sitter_parser]⁠

A parser.

language

⁠[tree_sitter_language]⁠

A language.

timeout

⁠[double(1)]⁠

A single whole number corresponding to a timeout in microseconds to use when parsing.

included_ranges

⁠[list_of<tree_sitter_range>]⁠

A list of ranges constructed by range(). These are the only locations that will be considered when parsing.

An empty list can be used to clear any existing ranges so that the parser will again parse the entire document.

Value

A new parser.

Examples

language <- treesitter.r::language()
parser <- parser(language)
parser_set_timeout(parser, 10000)
