  };
  const lines = rawLines.split(NEWLINE);
  const { start, end, markerLines } = getMarkerLines(loc, lines, opts);
  const hasColumns = loc.start && typeof loc.start.column === "number";

  const numberMaxWidth = String(end).length;

  const highlightedLines = highlighted ? highlight(rawLines, opts) : rawLines;

  let frame = highlightedLines
    .split(NEWLINE)
    .slice(start, end)
