仅引用同上引用的第一作者

Question

authoryear-icomp当使用BibLaTeX，我想仅引用多作者著作中的第一作者，即使这并不独特，当引用是重复的（例如 ibidem）时。我的理由是，ibidem 无论如何都可以唯一地标识参考文献。

我还没有找到办法，但考虑到 BibLaTeX 令人难以置信的灵活性，我怀疑这是可能的（我最近开始使用它，到目前为止很喜欢它）。 有可能实现上述目标吗？

考虑以下 MWE：

\documentclass{article}

\usepackage{filecontents}

\usepackage{csquotes}
\usepackage[%
    backend = biber,
    style = authoryear-icomp,
    giveninits = true,
    ibidpage = true,
    maxbibnames = 99,
    maxcitenames = 2,
    uniquename = init,
    useprefix = true
  ]{biblatex}
% always have first name, last name in bibliography
\DeclareNameAlias{sortname}{given-family}
\addbibresource{references.bib}

\begin{filecontents}{references.bib}
  @misc{keyA,
    title = {Title A},
    author = {First, Author and Second, Author and Third, Author},
    year = 2019,
  }

  @misc{keyB,
    title = {Title B},
    author = {First, Author and Fourth, Author and Fifth, Author},
    year = 2019,
  }
\end{filecontents}


\begin{document}

  We first note that~\textcite{keyA} and~\textcite{keyB} did a lot of work.
  The latter wrote \enquote{important stuff}, so we quote~\textcite{keyB} again.

  \printbibliography

\end{document}

渲染结果如下：

而不是渲染第一、第四等（同上）对于最后一个引用，我希望它能够呈现First 等人（同上）。然后读者只需找到前面的引用，就能唯一地识别正确的参考文献。使用 BibLaTeX 可以做到这一点吗？在此先感谢任何指点和帮助。

Answer 1

它不是特别漂亮，但是是可能的。

我们可以通过替换来获得所需的效果

\printnames{labelname}

在textcitebibmacro 中

\ifthenelse{\ifciteibid\AND\NOT\iffirstonpage}
  {\printnames[][1-1]{labelname}}
  {\printnames{labelname}}%

由于textcite宏authoryear-icomp很长，结果可能看起来有点令人生畏。

不幸的是，像我最初希望的那样，简单地maxnames在引用中注入一个不同的值是不够的，因为值可以被后端计算的-值覆盖（对于选项），这发生在很晚的阶段，因此标准钩子没有提供干扰的方法。\AtEveryCitekeymaxnameuniquelistmaxnameunqiuelist

如果你不喜欢长时间的重新定义，你当然可以使用xpatch来修补宏

\usepackage{xpatch}
\xpatchbibmacro{textcite}
  {\printnames{labelname}}
  {\ifthenelse{\ifciteibid\AND\NOT\iffirstonpage}
     {\printnames[][1-1]{labelname}}
     {\printnames{labelname}}}
  {}{}
