使用 biblatex 和 moderncv 创建参考书目-年份仅显示一次

Question

按照问题答案使用 biblatex 和 moderncv 创建参考书目，我想在出版物上显示年份，但每年只显示一次。

此示例打印每个年份

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@ARTICLE{a1,
 author = {Author},
 title = {Title},
 journaltitle = {Superjournal},
 year = {2003},
}
@article{a4,
 author = {Author4},
 title = {Title4},
 journaltitle = {Superjournal},
 year = {2003},
}
@article{a2,
 author = {Buthor},
 title = {Ztitle},
 journaltitle = {Superjournal},
 year = {2000},
}
@article{a3,
 author = {Duthor},
 title = {Ztitle},
 journaltitle = {Superjournal},
 year = {2002},
}
@InProceedings{p1,
 author = {Author},
 title = {Title},
 Booktitle = {conference xy},
 year = {2003},
}
@InProceedings{p4,
 author = {Author4},
 title = {Title4},
 Booktitle = {conference xy},
 year = {2003},
}
@InProceedings{p2,
 author = {Buthor},
 title = {Ztitle},
 Booktitle = {conference xy},
 year = {2000},
}
@InProceedings{p3,
 author = {Duthor},
 title = {Ztitle},
 Booktitle = {conference xy},
 year = {2002},
}

\end{filecontents*}

\documentclass{moderncv}

\usepackage[sorting=ydnt,

\begin{refsection}

我想删除每个子书目中的第二个 2003。

有人可以帮忙吗？

尝试

\makeatletter
\InitializeBibliographyStyle{\global\undef\bbx@lastyear}

\defbibenvironment{bibliography}
  {\list
     {\iffieldequals{year}{\bbx@lastyear}
       {}
       {\printfield{year}\savefield{year}{\bbx@lastyear}}}
     {\setlength{\topsep}{0pt}
      \setlength{\labelwidth}{\hintscolumnwidth}%
      \setlength{\labelsep}{\separatorcolumnwidth}%
      \leftmargin\labelwidth%
      \advance\leftmargin\labelsep}%
      \sloppy\clubpenalty4000\widowpenalty4000}
  {\endlist}
  {\item}
\makeatother

其灵感来自于如何authoryear以及怎样authortitle实现他们的dash选择\bbx@lasthash。

我们定义一个新的宏\bbx@lastyear来保存最后一条记录的年份，如果year当前记录的字段和\bbx@lastyear年份相符，我们就不必打印年份，否则我们打印年份​​并更新\bbx@lastyear。这是在

\iffieldequals{year}{\bbx@lastyear}
  {}
  {\printfield{year}\savefield{year}{\bbx@lastyear}}
