Function ErrorRecoveryLookaheadTokenLimit

parser/options.go:55–63

ErrorRecoveryLookaheadTokenLimit limits the number of lexer tokens that may be considered during error recovery. Error recovery often involves looking ahead in the input to determine if there's a point at which parsing may successfully resume. In some pathological cases, the parser can look through

(limit int)

		return nil

}
