Errors in structured form?

[mmontone]

Hi. Is it possible to get errors in a structured form? Similar to here: https://stackoverflow.com/a/26919119/4249433

{
  "message": "Expected \"AND\", \"ORDER BY\" or end of input but \"A\" found.",
  "expected": [
    {
      "type": "literal",
      "value": "AND",
      "description": "\"AND\""
    },
    {
      "type": "literal",
      "value": "ORDER BY",
      "description": "\"ORDER BY\""
    },
    {
      "type": "end",
      "description": "end of input"
    }
  ],
  "found": "A",
  "offset": 9,
  "line": 1,
  "column": 10,
  "name": "SyntaxError"
}

I'm considering using Peggy for auto-completion and would need this to implement.

Thanks!

Emm?? Errors always was in structured form:

peggy/lib/peg.d.ts

Lines 639 to 675 in 4036dab

	/** Thrown if the grammar contains a syntax error. */
	class SyntaxError extends Error {
	/** Location where error was originated. */
	public location: LocationRange;
	/**
	* List of possible tokens in the parse position, or `null` if error was
	* created by the `error()` call.
	*/
	public expected: Expectation[] | null;
	/**
	* Character in the current parse position, or `null` if error was created
	* by the `error()` call.
	*/
	public found: string | null;
	/**
	* Format the error with associated sources. The `location.source` should have
	* a `toString()` representation in order the result to look nice. If source
	* is `null` or `undefined`, it is skipped from the output
	*
	* Sample output:
	* ```
	* Error: Expected "!", "$", "&", "(", ".", "@", character class, comment, end of line, identifier, literal, or whitespace but "#" found.
	* --> my grammar:3:9
	* |
	* 3 | start = # 'a';
	* | ^
	* ```
	*
	* @param sources mapping from location source to source text
	*
	* @returns the formatted error
	*/
	public format(sources: SourceText[]): string;
	}
