带有自定义超链接的 BibLaTeX 自定义引用字符串

我想要一种自定义的引用样式，其中引用看起来像期刊和年份的简称，并超链接到 DOI 或期刊网站，而不是参考列表（参考书目）。

一种接近的方法是使用style=alphabetic并指定shorthand我想要的引用格式。

下面是一个尚未实现我想要的功能的 MWE：

\documentclass[english]{article}
\usepackage[style=alphabetic,maxnames=999,minalphanames=3,firstinits=true]{biblatex}
\usepackage{hyperref}
\begin{filecontents*}{\jobname.bib}
@book{tabmet,
  author    = {Ulrich Fischer and Max Heinzler and Roland Kilgus and Friedrich Näher and Stefan Oesterle and Heinz Paetzold and Werner Röhrer and Andreas Stephan and Ralf Winkow},
  title     = {Tabellenbuch Metall},
  edition   = {42},
  year      = {2002},
  publisher = {Verlag Europa-Lehrmittel},
  location  = {Haan-Gruiten},
  shorthand={Verlag 2002}
}
@article{fakeart,
  author    = {Walter Schnell and Dietmar Gross and Werner Hauger},
  title = {Technische Mechanik},
  volume    = {2},
  title     = {Elastostatik},
  edition   = {4},
  publisher = {Springer},
  date      = {2002},
  location  = {Berlin},
  journal={Journal of BibTeX examples},
  shorthand={J Bib Examp 2002}
}
\end{filecontents*}
%shorthand={\href{http://doi.org/10.1257/jep.23.1.221}{J Bib Examp 2002}}

\DeclareLabelalphaTemplate{
  \labelelement{
    \field[final]{shorthand}
    \field[strwidth=4,strside=left,ifnames=1]{labelname}
    \field[strwidth=2,strside=left,ifnames=2]{labelname}
    \field[strwidth=1,strside=left]{labelname}
  }
}
%            \field{usera}
\addbibresource{\jobname.bib}
\begin{document}
Citing these   \cite{tabmet,fakeart}
  \printbibliography
\end{document}

这会产生一个自定义的（实际上是在数据库中单独指定的，因此并不理想）引用格式，但它不允许我链接到外面。

也就是说，我想写

  shorthand={\href{http://doi.org/10.1257/jep.23.1.221}{J Bib Examp 2002}}

代替

  shorthand={J Bib Examp 2002}

但这样做会产生错误。我真正想要的是不使用 来做到这一点shorthand。我可以定义一种样式，使用url数据库中的字段和journal数据库中的字段，使引用表现得像

(\href{url}{journal year})

答案1

我认为最好将shorthand和 链接 分成不同的字段。这样你就不必费心处理\href，也不必执行不必要的格式化命令。

如果我们不想重复使用现有字段（如url等doi），则需要定义一个新字段来保存引用标签的链接。在下面的示例中，我将其称为。需要在文件中shorthandlink声明新字段（在下面的 MWE 中，文件是使用 生成的，在实际应用程序中，只需生成一次文件并将其放在 LaTeX 可以找到的地方）。biblatex.dbx.dbxfilecontents

有了shorthandfield可用的东西，就可以像更改负责将引文链接到参考书目的字段格式一样简单。

\documentclass[english]{article}

\begin{filecontents*}{shorthandlink.dbx}
\ProvidesFile{shorthandlink.dbx}[2020/11/15 arbitrary links for shorthands]
\DeclareDatamodelFields[type=field, datatype=uri]{shorthandlink}
\DeclareDatamodelEntryfields{shorthandlink}
\end{filecontents*}

\usepackage[style=alphabetic,
  maxnames=999, minalphanames=3, giveninits=true,
  datamodel=shorthandlink]{biblatex}

\usepackage{hyperref}

\DeclareFieldFormat{bibhyperref}{%
  \iffieldundef{shorthandlink}
    {\bibhyperref{#1}}
    {\ifhyperref
       {\href{\thefield{shorthandlink}}{#1}}
       {#1}}}

\begin{filecontents*}{\jobname.bib}

链接简写引用。

如果要重用现有的doi和url字段，则不需要该.dbx文件，但bibhperref字段格式需要稍微复杂一些。

\documentclass[english]{article}

\usepackage[style=alphabetic,
  maxnames=999, minalphanames=3, giveninits=true]{biblatex}

\usepackage{hyperref}

\DeclareFieldFormat{bibhyperref}{%
  \iffieldundef{doi}
    {\iffieldundef{url}
       {\bibhyperref{#1}}
       {\ifhyperref
          {\href{\thefield{url}}{#1}}
          {#1}}}
    {\ifhyperref
       {\href{https://doi.org/\thefield{doi}}{#1}}
       {#1}}}
