自定义作者列表格式

自定义作者列表格式

我想修改 BibLaTeX 的引用宏以便：

  1. 对于第一次引用，如果作者数量少于 5 人，则不管作者数量如何，都将其全部打印出来。
  2. 在所有其他情况下，请遵循正常的 APA 引用样式。

这是我目前所拥有的。它通过第一次打印出所有作者部分起作用，但似乎\ifthenelse总是评估为真并执行第一个分支（即，无论如何都打印出所有作者）

\documentclass[stu, 12pt, biblatex]{apa7}
% APA citation style
\usepackage{csquotes}
\usepackage{hyperref}
\addbibresource{cite.bib}

\usepackage{xpatch}
\xpatchbibmacro{cite}{\printnames{labelname}}%
{%
    \ifciteseen{%
        \printnames{labelname}%
    }{%
        \ifthenelse{\value{listtotal} < 6}{%
            \printnames[][-\value{listtotal}]{labelname}%
        }{%
            \printnames{labelname}%
        }%
    }%
}
{}{}

这是 Bib 文件

@book{6Authors,
  title = {6 authors},
  author = {Cao, Mina and Anish, Pruitt and Lulu, Douglas and Zahra, Sing and Wesley, Smith and Anish, Pruitt},
}

@book{5Authors,
  title = {5 authors},
  author = {Mina, Goyal and Anish, Pruitt and Lulu, Douglas and Zahra, Sing and Wesley, Smith},
}

@book{4Authors,
  title = {4 authors},
  author = {Lulu, Douglas and Anish, Pruitt and Mina, Goyal and Zahra, Sing},
}

@book{3Authors,
  title = {3 authors},
  author = {Wesley, Smith and Anish, Pruitt and Mina, Goyal},
}

@book{2Authors,
  title = {2 authors},
  author = {Zahra, Sing and Mina, Cao},
}

@book{1Author,
  title = {1 author},
  author = {Anish, Pruitt},
}

文档biblatex中提到listtotal（在第 189 页的描述中\printnames，重点是我的）：

每当\printnames处理\printlist列表时，可以通过四个计数器访问有关当前状态的信息：计数器listtotal保存当前列表中的项目总数，[...]。这些计数器旨在用于列表格式化指令。也可以在和的listtotal第二个可选参数中使用。\printnames\printlist请注意，这些计数器是列表格式指令的本地计数器，在其他地方使用时不会保存有意义的值。对于每个列表，还有一个同名的计数器，用于保存相应列表中的项目总数。例如，计数器author保存列表中的项目总数author。这些计数器与 listtotal 类似，但它们也可以独立于列表格式指令使用。

因此，在\ifthenelse（这不是列表格式指令）中listtotal，计数器没有有意义的值。相反，您必须使用计数器labelname来获取中的条目数labelname：

    }%
