如何使用 biblatex 获得完全超链接的作者年份引用？

Question

我想结合@moewe 的答案，这里和@lockstep，这里，使用 biblatex 获取完全超链接的作者年份引用，如下所示。

\documentclass{memoir}

\usepackage{xcolor}

\usepackage[backend=biber, defernumbers=true, bibstyle=authoryear,style=ext-authoryear]{biblatex}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
    @misc{A01,
        author = {Author, A.},
        year = {2001},
        title = {Alpha},
    }
\end{filecontents}

\bibliography{\jobname.bib}

%to be put citations in brackets
\DeclareOuterCiteDelims{parencite}{\bibopenbracket}{\bibclosebracket}

%%% To make author hyperlink, just like year, in citations
\DeclareCiteCommand{\parencite}[\mkbibparens]
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
    \printtext[bibhyperref]{\usebibmacro{citeyear}}}
{\multicitedelim}
{\usebibmacro{postnote}}

\usepackage[colorlinks=true, urlcolor=blue, linkcolor=violet, citecolor=violet]{hyperref}                   

\begin{document}

\parencite{A01}

\printbibliography
    
\end{document}

结果是完全超链接，尽管周围的元素是圆括号而不是方括号。

我怎样才能解决这个问题？

Answer 1

biblatex-ext通常\DeclareOuterCiteDelims通过 cite 命令的包装器定义来实现。即\parencite在标准中定义authoryear.cbx为

\DeclareCiteCommand{\parencite}[\mkbibparens]
  {\usebibmacro{prenote}}%
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

但ext-authoryear.cbx有

\DeclareCiteCommand{\parencite}[\mkouterparencitedelims]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

因此，如果你重新定义，\parencite你需要保留\mkouterparencitedelims。因此，

\DeclareCiteCommand{\parencite}[\mkbibparens]
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
    \printtext[bibhyperref]{\usebibmacro{citeyear}}}
{\multicitedelim}
{\usebibmacro{postnote}}

必须是

\documentclass{memoir}
\usepackage{xcolor}
\usepackage[backend=biber, style=ext-authoryear]{biblatex}
\usepackage[colorlinks=true, urlcolor=blue, linkcolor=violet, citecolor=violet]{hyperref}

\DeclareOuterCiteDelims{parencite}{\bibopenbracket}{\bibclosebracket}

\DeclareCiteCommand{\parencite}[\mkouterparencitedelims]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \printtext[bibhyperref]{\usebibmacro{citeyear}}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\addbibresource{biblatex-examples.bib}

\begin{document}
\parencite{sigfridsson}

\printbibliography
\end{document}

不过，这里有些不对劲。 的定义\parencite只打印年份 ( \usebibmacro{citeyear})。 它看起来更像是 的定义\parencite*。 要获得完整引文，您需要\usebibmacro{cite}。

请注意，如果你只是说，你可能会遇到双链接目标的问题

\DeclareCiteCommand{\parencite}[\mkouterparencitedelims]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \printtext[bibhyperref]{\usebibmacro{cite}}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

就像是

\documentclass{memoir}
\usepackage{xcolor}
\usepackage[backend=biber, style=ext-authoryear]{biblatex}
\usepackage[colorlinks=true, urlcolor=blue, linkcolor=violet, citecolor=violet]{hyperref}

\DeclareOuterCiteDelims{parencite}{\bibopenbracket}{\bibclosebracket}

\DeclareFieldFormat{citehyperref}{%
  \DeclareFieldAlias{bibhyperref}{noformat}% Avoid nested links
  \bibhyperref{#1}}

\DeclareCiteCommand{\parencite}[\mkouterparencitedelims]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \printtext[citehyperref]{\usebibmacro{cite}}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\addbibresource{biblatex-examples.bib}

\begin{document}
\parencite{sigfridsson}

\printbibliography
\end{document}

在这方面更安全（见超链接名称与 biblatex 作者年份 (biblatex 1.4b)）。
