参考书目右侧有二维码吗？

Question

我已设法获取biblatex并biber包含包含 URL 的参考书目项目的二维码 - 如下所示：

\documentclass{scrartcl}

\begin{filecontents*}[overwrite]{\jobname.bib}
@book { texlive-home,
  shorthand = {TLD1},
  author    = {The TeX User Group},
  title     = {TeX Live},
  note      = {some text to make the entry appear more voluminous},
  url       = {https://www.tug.org/texlive/}
}
\end{filecontents*}

\begin{filecontents*}[overwrite]{biblatex.cfg}
\DeclareFieldFormat
  [book]
  {url}{\par{\scriptsize\ttfamily\url{#1}}\par\vspace{1.5mm}\qrcode{#1}\vspace{3mm}}
\end{filecontents*}

\usepackage{qrcode}
\usepackage[style=alphabetic]{biblatex}
\appto{\biburlsetup}{\renewcommand*{\UrlFont}{\scriptsize\ttfamily}}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}

这可行，但浪费了大量空间：

我希望二维码位于条目的右侧，如下所示：

在文档中我可能会使用一个简单的tabular环境来实现这一点，但我所能创建的只是令人印象深刻的错误消息。有人能给我指明正确的方向吗？

如果你更喜欢真正的表格书目，你可能想看看biblatex-ext-tabular我的biblatex-ext捆。

使用表格的优点是您将始终有足够的空间放置二维码。

\documentclass{scrartcl}

\usepackage{qrcode}
\usepackage[style=alphabetic]{biblatex}
\usepackage{biblatex-ext-tabular}

\usepackage{longtable}
\usepackage{array}
\newcolumntype{L}[1]{%
  >{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}

\DeclareFieldFormat{qrurl}{%
  \raisebox{\dimeval{-\height+\ht\strutbox}}{\qrcode{#1}}}

\defbibtabular{bibtabular}
  {\setlength{\LTpre}{0pt}%
   \setlength{\LTpost}{0pt}%
   \renewcommand*{\arraystretch}{2}%
   \begin{longtable}{%
   @{}
   L{\labelalphawidth}
   L{\dimexpr0.7\textwidth-0.7\labelalphawidth\relax}
   L{\dimexpr0.3\textwidth-0.3\labelalphawidth\relax}
   @{}}}
  {\end{longtable}}
  {\anchorlang{%
     \printtext[labelalphawidth]{%
       \printfield{labelprefix}%
       \printfield{labelalpha}%
       \printfield{extraalpha}}} &
   \driver{} &
   \plain{\printfield[qrurl]{url}}
    \\}

\begin{filecontents*}{\jobname.bib}
@book{texlive-home,
  shorthand = {TLD1},
  author    = {The TeX User Group},
  title     = {TeX Live},
  note      = {some text to make the entry appear more voluminous},
  url       = {https://www.tug.org/texlive/}
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\addbibresource{biblatex-examples.bib}

\begin{document}
\nocite{texlive-home,sigfridsson,worman,geer,nussbaum,ctan}
\printbibtabular
\end{document}

您将必须调整尺寸，但是这样的方法应该可以起作用。

\documentclass{scrartcl}

\usepackage{qrcode}
\usepackage[style=alphabetic,url=false]{biblatex}
\appto{\biburlsetup}{\renewcommand*{\UrlFont}{\scriptsize\ttfamily}}
\addbibresource{biblatex-examples.bib}
\usepackage{lipsum}
\DeclareFieldFormat
  {qrurl}{\qrcode{#1}}

\renewbibmacro{begentry}{\makebox[0pt][l]{\hspace*{\linewidth}\quad\raisebox{\dimeval{-\height+\ht\strutbox}}[0pt][0pt]{\printfield[qrurl]{url}}}}

\defbibenvironment{bibliography}
  {\list
     {\printtext[labelalphawidth]{%
        \printfield{labelprefix}%
        \printfield{labelalpha}%
        \printfield{extraalpha}}}
     {\setlength{\labelwidth}{\labelalphawidth}%
      \setlength\rightmargin{3cm}% %<------- adapt ...
      \setlength{\leftmargin}{\labelwidth}%
      \setlength{\labelsep}{\biblabelsep}%
      \addtolength{\leftmargin}{\labelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\parsep}{\bibparsep}}%
      \renewcommand*{\makelabel}[1]{##1\hss}}
  {\endlist}
  {\item}    
\begin{document}
\lipsum[1]

\cite{ctan,doody}
\printbibliography
\end{document}
