use_parser_error_recovery

Enable error recovery in the SQL parser.

When this option is enabled, postgresql-cst-parser attempts to recover from certain syntax errors and continues formatting.

Internally, this feature relies on the parse_2way function of postgresql-cst-parser. You can refer to the original source code and documentation here.

Options

  • true (default): Enable parser error recovery and format even when the SQL has syntax errors.
  • false: Disable parser error recovery. If a parse error occurs, the formatter returns an error without modifying the SQL.

Example

With error recovery enabled, SQL like the following can be formatted without raising a parse error.

SELECT
,	/*foo*/
,	/*bar*/
FROM
,	/*#baz*/
,	/*#qux*/
WHERE
AND	1	=	1
AND	2	=	2
ORDER BY
,	1
,	2
;
