Custom sorting using the matched indices

[TzeroOcne]

I have this custom sorting function from my nvim-cmp config and I want to migrate it to blink.cmp

---@param entry cmp.Entry
function M.expand_matches(entry)
  ---@type (integer|nil)[]
  local position_list = {}
  for _, value in ipairs(entry.matches) do
    for i = value.word_match_start, value.word_match_end do
      position_list[#position_list+1] = i
    end
  end

  return position_list
end

---@type cmp.ComparatorFunction
function M.positions(entry1, entry2)
  local matches1 = M.expand_matches(entry1)
  local matches2 = M.expand_matches(entry2)

  for index = 1, math.min(#matches1, #matches2) do
    local pos1 = matches1[index]
    local pos2 = matches2[index]
    if not pos1 or not pos2 then
      if pos1 then
        return true
      end
      if pos2 then
        return false
      end
      return nil
    end

    if pos1 ~= pos2 then
      return pos1 < pos2
    end
  end

  if #matches1 ~= #matches2 then
    if #matches1 == 0 or #matches2 == 0 then
      return #matches1 ~= 0
    end

    local line1 = entry1.context.cursor_before_line
    local line2 = entry2.context.cursor_before_line
    local line = #line1 > #line2 and line1 or line2
    local offset = math.min(entry1.source_offset, entry2.source_offset)
    local word = string.sub(line, offset)

    if #matches1 == #word then
      return true
    end
    if #matches2 == #word then
      return false
    end

    return #matches1 > #matches2
  end

  return nil
end

the problem is I need the matched indices but it's not available in blink sort item, is it possible to add matched indices on sorting item? or is it already there and I just don't realize it?

@TzeroOcne I'm not quite sure, but you might be referring to this Sorting.

I know about custom sorting in blink but when I try to implement my own custom sorting it doesn't have what I need which is matched indices
