如何将参考书目中的姓氏变为小写，除了当关键字为“primary”时，如何为“author”添加注释？是的，我知道我可以全部使用 \textsc{…}，但我希望这个过程可以自动化。
我认为我的问题的答案将衍生自https://tex.stackexchange.com/a/29862/60686。

我想要的是，“Roehrs”和“Mertens”将采用小写字母，而“von Aue”将采用普通字体（忽略“von Aue”就像“da Vinci”一样，严格来说不是姓氏，但无论如何）。
答案1
我们可以使用\ifkeyword内部\mkbibnamelast
\renewcommand*{\mkbibnamelast}[1]{%
\ifkeyword{primary}
{#1}
{\textsc{#1}}}
仅检查primary，但你可以将它与更复杂的解决方案结合起来将作者姓氏设置为小写，但编辑、翻译等使用 biblatex 时应避免使用到
\def\ifmknamesc{%
\ifboolexpr{ test {\ifcurrentname{labelname}}
or test {\ifcurrentname{author}}
or ( test {\ifnameundef{author}} and test {\ifcurrentname{editor}} ) }}
\renewcommand*{\mkbibnamelast}[1]{%
\ifboolexpr{test {\ifkeyword{primary}} and test {\ifmknamesc}}
{#1}
{\textsc{#1}}}
您可以将相同的方法应用于\mkbibnameprefix“von”部分、\mkbibnamefirst名字和\mkbibnameaffix“junior”部分。在 MWE 中，我们更改了姓氏和“von”部分，但其余部分保持不变。
