我需要提交我的作品。出版商有以下要求。使用作者年份引用法。
对于有 2 位作者的作品，所有引用均包含两位作者；对于有 3 至 5 位作者的作品，在第一次引用时包含所有作者，并在后续引用中使用第一作者姓名和“et al.”：对于有 6 位或更多作者的作品，所有引用均使用第一作者姓名和“et al.”。
在我的文档中
我有以下设置。
\usepackage[style=authoryear-comp, giveninits, hyperref=auto, uniquename=mininit, maxbibnames=99, maxcitenames=5, url=false, doi=false, backend=biber,sortcites, sorting=nyt]{biblatex}
\DeclareNameAlias{author}{last-first}
\DefineBibliographyStrings{english}{
page = {\ifbibliography{}{\adddot}},
pages = {\ifbibliography{}{\adddot}},
}
我意识到 maxcitenames=5 应该是这样的
\如果第一次遇到则大于 2 且小于 6 则为 5 但如果不是第一次遇到则为 1 但如果只有 2 则始终为 2 等等
我还需要将页面格式化为（第 3-4 页），除非这是参考书目中的最后一个字段，否则请保持原样
我对 if 语句感到困惑，并且不理解语法结构
我没有创建标签 pagination、maxcitenames 和 if 的代表。这些可能与这个问题相关。
感谢您的帮助
答案1
选项的值(min|max)(bib|cite)?names只能是大于或等于一的整数，它们不能包含条件，并且您不能有条件地设置选项（不过，您可以手动设置相应的计数器，该选项的作用也仅限于此，但它会将值传递到后端，在后端，该值可能与唯一性和标签计算相关）在文档内（此时您知道您是第一次引用还是后续引用）。您必须在没有这些选项帮助的情况下实现该行为。
一个自然的方法是apa.cbx，第 98-177 页
% Can't do this with the built-in printnames format as APA requires truncation
% and disambiguation only after first cite
% We either use uniquelist or minnames for truncation. If uniquelist isn't
% defined, we fall back on minnames
%
% \printnames does different things depending on whether the format you are
% calling is the default for the name field or is a custom format:
%
% max/minnames truncation is done before calling the format so we have
% to do \printnames[format][-\value{listtotal}]{field} to ensure we get
% all of the names in the list to work on here
%
% Explicit "and others" is dealt with in labelname:doname via a custom name:andothers
\DeclareNameFormat{labelname}{%
% First set the truncation point
\ifthenelse{\value{uniquelist}>1}
{\numdef\cbx@min{\value{uniquelist}}}
{\numdef\cbx@min{\value{minnames}}}%
% Always print the first name and the second if there are only two since
% "et al" must always be plural
\ifboolexpr{test {\ifnumcomp{\value{listcount}}{=}{1}}
or test {\ifnumcomp{\value{listtotal}}{=}{2}}}
{\usebibmacro{labelname:doname}%

{\namepartprefixi}%

% We are looking at name >=3
% If the list is 6 or more names or we have seen citation before, potential truncation
{\ifboolexpr{test {\ifnumcomp{\value{listtotal}}{>}{5}}
or test {\ifciteseen}}
% Less than the truncation point, print normally

本质上，样式确保始终调用\printnames{labelname}as\printnames[labelname][-\value{listtotal}]{labelname}以始终获取所有名称，而不管任何maxnames截断。然后，名称格式会遍历不同的情况，并且仅在您希望看到的情况下在列表中打印名称。它还考虑到该uniquelist功能并确保等指的是多位作者，因此它比人们最初想象的要复杂一些。
一个更简单的版本可以忽略这些细微差别，并与 一起工作，authoryear-comp如下所示。与默认版本相比，cite和bibmacros 的修改仅在于的交换。宏保留名称格式的原始定义，而不包含 的代码textcite\printnames{labelname}\printnames[labelname][-\value{listtotal}]{labelname}labelname:indivlabelname等。

但是，您对所需输出的描述完全符合 APA 规则，并且您的其余设置也让我怀疑您想要非常接近（即使不是完全符合）的 APA 样式。因此，也许您最好使用
\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[style=apa, backend=biber]{biblatex}

一个警告：biblatex-apa尽可能接近地实现 APA 样式biblatex（可能甚至与 LaTeX 总体而言，APA 样式的另一种 LaTeX 实现是基于 BibTeX 的apacite），这意味着它非常复杂，不像标准样式那样容易定制。因此，如果您不需要 APA 样式，您可以将其用作biblatex-apa基础，但根据您的需求，实现所需的修改可能比在标准样式中更棘手。
