縮寫 biblatex 中顯示的作者 + 年份，不超過 1 行

Question

我正在為我的論文設定我的biblatex論文，並意識到簡單地將顯示的作者限制為參考書目中的某個值（例如\maxbibnames=5& \minbibnames=5）。然而，我希望實現包括（年份）在內的作者行限制為 number=X （假設 5 個顯示的作者），但也不超過第一行。因此，如果「authors incl.（year）」在文件中需要超過 1 行，biblatex 會簡單地剪切比最初用\maxbibnames/定義的更多的書目名\minbibnames（但當然僅適用於這個條目）。

現在的例子：

愛因斯坦，A.、特斯拉，N.、瓊斯，I.、傑佛遜，T. 和胡德，R.

等人。 （1980）。一篇非常好的論文。自然 1：100-150。

新縮寫範例：

愛因斯坦，A.，特斯拉，N.，瓊斯，I. 和傑斐遜，T. 等人。 （1980）。

一篇非常好的論文。自然 1：100-150。

以下程式碼只是計算名稱數量並檢查它們是否適合一行。

巨集的原始定義取自authoryear.bbx，我們只添加一個薄包裝器來倒數計時並測量輸出長度。
