Biblatex：动态引用命令中的 vgl. 和编号问题

Question

您可能喜欢以下修改

问题 1 可以通过重新定义multicite multiprenotebibmacro 来解决。如果遇到这种prenote情况，我们会重新定义multiprenote添加“vgl”注释，并重新定义prenote不这样做的正常情况。

问题 2 可以通过禁用用于评估文本长度的框中的脚注命令来解决。该命令cquotation会在其参数中对文本进行两次排版：一次是不可见的，以检查其长度（以决定如何处理文本），另一次是正确排版；不可见的排版也会增加脚注编号，因此您会得到双倍步骤。

\renewbibmacro*{multiprenote}{%
  \renewbibmacro*{prenote}{%
    \iffieldundef{prenote}
      {}
      {\printfield{prenote}%
       \setunit{\prenotedelim}}}%
  \iffieldundef{multiprenote}{%
    \ifbool{withintextquote}{%
    }{%
      \bibstring{compare}\addspace
    }%
    }
    {\printfield{multiprenote}%
     \setunit{\prenotedelim}}}

\renewbibmacro*{prenote}{%
  \iffieldundef{prenote}{%
    \ifbool{withintextquote}{%
    }{%
      \bibstring{compare}\addspace
    }%
    }
    {\printfield{prenote}%
     \setunit{\prenotedelim}}}

\makeatletter
\newcommand{\cquotation}[1]{%
    \begingroup
    \booltrue{withintextquote}%
    % \settowidth doesn't like paragraphs
    \setbox\@tempboxa\hbox{%
        \def\par{\hspace{3\linewidth}}% If a paragraph is included force long form
        %\let\par\space  % Ignore paragraphs
        \let\footnote\@empty% make sure autocite does not do anything here; this is new
        \let\autocite\@empty
        #1}%
    \ifdim\wd\@tempboxa>3\linewidth
        \begin{quote}
            \itshape
            #1
        \end{quote}
    \else
        {\itshape #1}%
    \fi
    \endgroup}
\makeatother

然后我们的 MWE 得出

在此处输入图片描述

如果您使用，csquotes您可能想看看blockquote，这是一个非常复杂的内联/段落切换实现。

我们还可以借用内部宏来实现我们的目的：\blockquote@parsehook禁用 LaTeX 代码中所有不需要的脆弱部分，例如脚注、边注、标签和索引命令savebox。甚至还有一个命令供用户添加要在blockquote评估中禁用的命令：\BlockquoteDisable{}。

命令\cquotation则变成。

\makeatletter
\newcommand{\cquotation}[1]{%
    \begingroup
    \booltrue{withintextquote}%
    % \settowidth doesn't like paragraphs
    \setbox\@tempboxa\vbox{%
        \def\par{\hspace{3\linewidth}}% If a paragraph is included force long form
        %\let\par\space  % Ignore paragraphs
        %\let\blx@thecheckpunct\@gobble
        \blockquote@parsehook
