Biblatex、authoryear-comp 和超链接

Biblatex、authoryear-comp 和超链接

回答这个问题奥黛丽提出一个答案与该authoryear选项配合得很好。

(上下文：我试图让引文中的超链接包含作者姓名，而不仅仅是年份。奥黛丽提供了一个适用于 的解决方案authoryear，我正在尝试使其适应authoryear-comp。)

我正在尝试调整答案以使其与 兼容authoryear-comp。以下是我尝试的方法（它不起作用---我收到一条错误消息：Latex Error: ./biblatex.tex:96 Argument of \@secondoftwo has an extra }. Runaway argument?）：

\renewbibmacro*{cite}{%
\printtext[bibhyperref]{% Enclose cite macro output in hyperlink
    \global\togglefalse{cbx:hyperref}% Prevent nested hyperlinks
  \iffieldundef{shorthand}
    {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
       {\usebibmacro{cite:label}%
    \setunit{\addspace}%
    \usebibmacro{cite:labelyear+extrayear}%
        \usebibmacro{cite:reinit}}
       {\iffieldequals{namehash}{\cbx@lasthash}
          {\ifthenelse{\iffieldequals{labelyear}{\cbx@lastyear}\AND
                       \(\value{multicitecount}=0\OR\iffieldundef{postnote}\)}
             {\setunit{\addcomma}%
              \usebibmacro{cite:extrayear}}
             {\setunit{\compcitedelim}%
              \usebibmacro{cite:labelyear+extrayear}%
              \savefield{labelyear}{\cbx@lastyear}}}
          {\printnames{labelname}%
       \setunit{\nameyeardelim}%
           \usebibmacro{cite:labelyear+extrayear}%
           \savefield{namehash}{\cbx@lasthash}%
           \savefield{labelyear}{\cbx@lastyear}}}}
    {\usebibmacro{cite:shorthand}%
     \usebibmacro{cite:reinit}}%
\global\toggletrue{cbx:hyperref}}
  \setunit{\multicitedelim}}

我不完全了解\cite在 下是如何工作的authoryear-comp，所以也许有人知道可以做到这一点？（我认为这是可能的，因为这是在 BibTeX 中实现超链接的方式。）

编辑（关于 Marco 的评论）：这是一个最简单的例子：

\documentclass{article}

    {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
       {\usebibmacro{cite:label}%

                       \(\value{multicitecount}=0\OR\iffieldundef{postnote}\)}
             {\setunit{\addcomma}%

我正在使用biblatex-example数据库中的引用。我得到的错误是：Paragraph ended before \@secondoftwo was complete.

我更喜欢另一种解决方案：

\makeatletter
%Works without the last bracket ;-)
\let\abx@macro@citeOrig\abx@macro@cite
\renewbibmacro{cite}{%
   \bibhyperref{%
   \let\bibhyperref\relax\relax%
   \abx@macro@citeOrig%
   }%
}
\let\abx@macro@textciteOrig\abx@macro@textcite
\renewbibmacro{textcite}{%
   \bibhyperref{%
   \let\bibhyperref\relax\relax%
   \abx@macro@textciteOrig%
   }%
}%
\makeatother

您可以将它用于每个 cite 命令。

\documentclass{article} 
\usepackage[utf8]{inputenc} 
\usepackage[style=authoryear-comp,backend=biber,hyperref]{biblatex} 
\usepackage[colorlinks]{hyperref} 
\bibliography{biblatex-examples} 

\makeatletter
%Works without the last bracket ;-)
\let\abx@macro@citeOrig\abx@macro@cite
\renewbibmacro{cite}{%
   \bibhyperref{%
   \let\bibhyperref\relax\relax%
   \abx@macro@citeOrig%
   }%
}
\let\abx@macro@textciteOrig\abx@macro@textcite
\renewbibmacro{textcite}{%
   \bibhyperref{%
   \let\bibhyperref\relax\relax%
   \abx@macro@textciteOrig%
   }%
}%
\makeatother


\begin{document} 
A reference to \parencite{kastenholz,sigfridsson} and~\cite{sigfridsson}. 
\printbibliography 
\end{document}

编辑：

我改变了上面例子的代码。

\makeatletter
   \patchcmd{\blx@citeprint}%
           {\blx@loopcode}%
           {\blx@imc@bibhyperlink{#1}‌​‌​{\blx@loopcode}}%
           {}{}
\makeatother

问题：最后一个括号不是链接的一部分。

答案2

\cite和都在的参数内\textcite使用。如果您只是在 中包装（或和书目宏），链接将包含标点符号。此外， 的打印被推迟到下一个或命令。因此很难确保这种方法会创建指向书目中正确项目的链接。\setunit<loopcode>\DeclareCiteCommand<loopcode>citetextcite\bibhyperref\setunit\print*\bibstring

以下补丁将在适当的情况下为/和+cite生成单个链接。补丁将在缺少和时在+周围添加括号。否则将应用单独的链接，类似于使用 natbib 获得的引用链接。labelnamelabellabelyearextrayeartextcitelabelyearextrayearprenotepostnote

这是使用 biblatex 2.6 或更早版本时应获得的输出。这些补丁也适用于更高版本，其中\textcite和朋友将and字符串合并到最终的引用分隔符中。
