Biblatex：更改“prenote”字段的顺序

Question

我正在尝试更改仅针对特定 的\footcite使用顺序。例如，如果我尝试对 执行此操作，我该如何实现。我想要以下顺序：biblatexentrytype\ifentrytype{commentary}

shorthand，，prenote​postnote

\usebibmacro{prenote}我的想法是战争来改变\DeclareCiteCommand{\footcite}

参见附件示例：

The idea was to just change the position of \verb|\usebibmacro{prenote}|
\footcite[Armbrüster][§ 138 Rn. 11]{citekey}\\
But sadly it doesn't change anything.


\printbibliography[title=Bibliography]
\end{document}

知道如何实现如图所示的顺序吗？

Answer 1

实际上不起作用\AtEveryCite，因为您无法在已经执行引用命令的位置重新定义它。因此重新定义必须在 之外进行\AtEveryCite。

另一方面，\ifentrytype必须在知道所处理条目的条目类型时执行。如果我们只是执行，情况就不是这样了\ifentrytype{commentary}{...redefine \footcite here...}{...keep the original definition...}，所以这也行不通。一个可能的解决方案是

\DeclareCiteCommand{\footcite}%
  {\ifentrytype{commentary}{}{\usebibmacro{prenote}}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}%
   \ifentrytype{commentary}{\usebibmacro{prenote}}{}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

但这样你就无法为类型添加真正的预注。所以我认为以这种方式@commentary滥用论点的想法在概念上是有缺陷的。prenote

相反，你可以考虑类似的解决方案biblatex \cite 中另一个可选参数内的可选参数。这个想法不是滥用参数，而是可以通过圆括号prenote将另一个可选值传递给命令： 。postnote\autocite[(Armbrüster)§ 138 Rn. 11]{citekey}
