使用分割框架对投影仪中的引文进行编号

使用分割框架对投影仪中的引文进行编号

我对 beamer 中分割帧中的命令编号有疑问\footfullcite{}。我想增加每个引用命令的引用计数器，即使这些命令不在同一显示页面上。如果标题已被引用，它应该获得与第一个引用相同的编号。在最后一页，\printbibliography应该按引用顺序对引用进行排序，并将相应的编号设置为项目。我知道，脚注引用与普通引用有所不同，无论如何，我希望脚注引用的行为与标准引用在样式上具有类似的行为biblatex numeric。

这是一个示例代码，我在其中评论了所需的行为。

\documentclass[aspectratio=169]{beamer}
\usepackage[language=english, backend=biber, style=authoryear]{biblatex}
\usepackage{filecontents}

\begin{filecontents*}{exampleReferences.bib}
@book{foo1,
  year = {2001},
  title = {Example title 1},
  author = {John One}
}

@book{foo2,
  year = {2002},
  title = {Example title 2},
  author = {John Two}
}
\end{filecontents*}

\addbibresource{exampleReferences.bib}

\begin{document}
\begin{frame}{Example frame 1}
Text on frame that doesn't change.\\

%This citation should be marked with a 1
\only<1>{Special text foo1 to be cited \footfullcite{foo1}}

%This citation should be marked with a 2, as it is the second citation and different from the first citation
\only<2>{Another special text to be cited \footfullcite{foo2}}

%This should be marked once again with 1, as it was already cited before.
\only<3>{Another passage of special text foo1 to be citeted \footfullcite{foo1}}
\end{frame}

\begin{frame}{Example frame 2}
%The reference on a new frame should get the same marker if it was already cited (here it should get a 2)
New frame with reference to already referenced text \footfullcite{foo2}
\end{frame}

\begin{frame}{Bibliography}
%The bibliography of all cited texts. 
%It should be sorted in citation-order and have a citation-number item instead of the image [e.g. [1]~\cite{foo1}].
\printbibliography
\end{frame}
\end{document}

有什么建议么？

最简单的方法似乎是基于该风格numeric并supercite用两遍结构进行修改，这样我们就可以为每个引用获得单独的脚注。

\documentclass[aspectratio=169]{beamer}
\usepackage[backend=biber, style=numeric, sorting=none]{biblatex}

\setbeamertemplate{bibliography item}{\insertbiblabel}

\makeatletter
\newcommand*{\mkblankfootnote}[1]{%
  \begingroup
    \renewcommand\thefootnote{}%
    \footnotetext{\bibfootnotewrapper{#1}}%
  \endgroup
}

\newcommand*{\mkbibsupercite}[1]{%
  \def\cbx@savedcites{\cbx@footfullcite}%
  \mkbibsuperscript{\mkbibbrackets{#1}}%
  \cbx@savedcites}

\DeclareCiteCommand{\supercite}[\mkbibsupercite]
  {\gdef\cbx@savedkeys{}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}%
     {}%
   \xappto\cbx@savedkeys{\thefield{entrykey},}}
  {\supercitedelim}
  {\protected@xappto\cbx@savedcites{%
     [\thefield{prenote}][\thefield{postnote}]{\cbx@savedkeys}}}

\DeclareCiteCommand{\cbx@footfullcite}
  {}
  {\mkblankfootnote{%
     \printtext[labelnumberwidth]{%
       \usebibmacro{cite}%
     }%
   \setunit{\addspace}%
   \usedriver
     {\DeclareNameAlias{sortname}{default}}
     {\thefield{entrytype}}}}
  {}
  {}
\makeatother

\usepackage{filecontents}
\begin{filecontents*}{exampleReferences.bib}
@book{foo1,
  year = {2001},
  title = {Example title 1},
  author = {John One}
}

@book{foo2,
  year = {2002},
  title = {Example title 2},
  author = {John Two}
}
\end{filecontents*}

\addbibresource{exampleReferences.bib}

\begin{document}
\begin{frame}{Example frame 1}
Text on frame that doesn't change.

%This citation should be marked with a 1
\only<1>{Special text foo1 to be cited \supercite{foo1}}

%This citation should be marked with a 2, as it is the second citation and different from the first citation
\only<2>{Another special text to be cited \supercite{foo2}}

%This should be marked once again with 1, as it was already cited before.
\only<3>{Another passage of special text foo1 to be citeted \supercite{foo1}}
\end{frame}

\begin{frame}{Example frame 2}
%The reference on a new frame should get the same marker if it was already cited (here it should get a 2)
New frame with reference to already referenced text \supercite{foo2}
\end{frame}

\begin{frame}{Bibliography}
%The bibliography of all cited texts. 
%It should be sorted in citation-order and have a citation-number item instead of the image [e.g. [1]~\cite{foo1}].
\printbibliography
\end{frame}
\end{document}

这只是一个简单的技巧，缺点请参见moewes 评论。

\documentclass[aspectratio=169]{beamer}

  author = {John One}

@book{foo2,
  year = {2002},
  title = {Example title 2},
  author = {John Two}
}
\end{filecontents*}

\addbibresource{exampleReferences.bib}
\setbeamertemplate{bibliography item}[text]

\makeatletter
\DeclareCiteCommand{\cite}[\mkbibsuperscript]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%

\renewbibmacro*{cite}{%

    \printfield{labelnumber}%
    \ifbool{bbx:subentry}{%

    }{}%
  }%
  \footnotetext[\thefield{labelnumber}]{%
    \usedriver{\DeclareNameAlias{sortname}{default}}{\thefield{entrytype}}

\begin{frame}{Example frame 2}
%The reference on a new frame should get the same marker if it was already cited (here it should get a 2)
New frame with reference to already referenced text \cite{foo2}

\begin{frame}{Bibliography}
