Create a new tree-sitter tree for a JSONC document — ts_tree_new.ts_language

The result is a ts_tree object. A ts_tree object may be queried, edited, formatted, written to file, etc. using ts_tree methods.

Usage

# S3 method for class 'ts_language_jsonc'
ts_tree_new(
  language,
  file = NULL,
  text = NULL,
  ranges = NULL,
  fail_on_parse_error = TRUE,
  options = NULL,
  ...
)

Arguments

language: Language of the file or string, a ts_language object,e.g. the return value of tsjsonc::ts_language_jsonc().
file: Path of a file to parse. Use either file or text, but not both.
text: String to parse. Use either file or text, but not both.
ranges: Can be used to parse part(s) of the input. It must be a data frame with integer columns start_row, start_col, end_row, end_col, start_byte, end_byte, in this order.

A ts_tree object representing the parse tree of the input. You can use the single bracket `[` operator to convert it to a data frame.
