TeX 中是否有类似于 \emptyauthor 和 \emptyaffil 的符号？

Question

我尝试使用包在 TeX 文档中实现 2 个标题titling。

类似的事情发生在如何重置作者列表？，但此解决方案仅适用于每个标题有 1 位作者和 1 个隶属关系的情况。相反，我每个标题有 2 位作者和 2 个隶属关系。由于代码原因，我得到第二个标题有 4 位作者和 4 个隶属关系，这并不合适！

\emptythanks正如您在 WE 中看到的，包中有一个功能对我来说很好，找到类似和的titling功能会很棒。但也许还有另一种方法可以解决这个问题……\emptyauthor\emptyaffil

有人能帮帮我吗？！

Answer 1

您应该能够使用以下命令重置作者和所属机构：

\renewcommand\AB@authlist{}
\renewcommand\AB@affillist{}
\renewcommand\AB@authors{}
\renewcommand\AB@affilsep{\protect\Affilfont}
\renewcommand\AB@blk@and{\protect\Authfont\protect\AB@setsep}

前三行用于清空存储作者和所属关系的宏。最后两行是必需的，因为这些宏在第一次使用后将被设置为其他内容。因此，如果我们想重新使用它们，我们需要将它们重置为初始状态。

将此方法应用到您的示例中：

\documentclass[12pt]{article}
%\usepackage[cp1251]{inputenc}
\usepackage[english]{babel}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amsthm}
\usepackage{dsfont}
\usepackage{amssymb}
\usepackage{csquotes}
\usepackage{titling}
\usepackage{letltxmacro}
\usepackage{xparse}
\usepackage[blocks]{authblk}

\makeatletter 

\newcommand{\emptyauthoraffil}{
  \renewcommand\AB@authlist{}
  \renewcommand\AB@affillist{}
  \renewcommand\AB@authors{}
  \renewcommand\AB@affilsep{\protect\Affilfont}
  \renewcommand\AB@blk@and{\protect\Authfont\protect\AB@setsep}
}

\LetLtxMacro\@uthorfrom@uthblk\author

\RenewDocumentCommand{\author}{+o+m}{%
  \ifnum0=\value{authors}%
  \def\AB@authors{}%
  \fi
  \IfValueTF{#1}{%
    \@uthorfrom@uthblk[#1]{#2}%
  }{%
    \@uthorfrom@uthblk{#2}%
  }%
}

\def\@maketitle{%
    \begin{center}%
      \let \footnote \thanks
      {\LARGE \@title \par}%
      \vskip 1.5em%
      {\large
        \lineskip .5em%
        \begin{tabular}[t]{c}%
          \@author%
        \end{tabular}\par}%
        \vskip 1em%
        % {\large \@date}%
      \end{center}%
      \par
      \vskip 1.5em%
      % reset counters for possible next \author macro
      \setcounter{authors}{0}%
      \setcounter{affil}{0}%
    }
    
\makeatother
