How to reset the author list?

Question

I am using titling package and authblk to manage multiple articles in a single file. Below is the code for example

\documentclass[11pt,openany]{article}
\usepackage{amsmath,amsfonts,amsthm,dsfont,amssymb,csquotes}
\usepackage{titling}

\usepackage[blocks]{authblk}


\usepackage{geometry}
\geometry{
    headheight=4ex,
    includehead,
    includefoot
}

\geometry{
    %   paper=a4paper, % Change to letterpaper for US letter
    paperheight=25cm,paperwidth=18cm,
    inner=1cm, % Inner margin
    outer=2cm, % Outer margin
    bindingoffset=1cm, % Binding offset
    top=1cm, % Top margin
    bottom=1cm, % Bottom margin
    %   showframe,% show how the type block is set on the page
}


\makeatletter
\newcommand\receivedon[1]{\renewcommand\@receivedon{#1}}
\newcommand\@receivedon{}
\newcommand\acceptedon[1]{\renewcommand\@acceptedon{\underline{\hspace{1.7cm}}#1}}
\newcommand\@acceptedon{}
\newcommand\uniqueid[1]{\renewcommand\@uniqueid{\text{#1}}}
\newcommand\@uniqueid{}
\newcommand\category[1]{\renewcommand\@category{\text{#1}}}
\newcommand\@category{}
\setlength{\droptitle}{-5cm}

\def\@maketitle{%
    \begin{minipage}{.5\textwidth}
        %       \raggedright
        $\begin{array}{lcl}
        \text{Unique Id} & :& \@uniqueid  \\
        \text{Category} & : & \@category  \\
        \end{array} $
    \end{minipage}
    \begin{minipage}{.5\textwidth}
        \raggedleft
        Received on : \@receivedon \\
        Accepted on : \@acceptedon
    \end{minipage}
    \vskip 1.5em%
    \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}

Thanks in advance.

Answer 1

I focused on resetting the author list of authblk package.

The list of authors is stored in \AB@authors which can be reset manually by defining it to be empty before each new title of an article is used.

Another way is to grab the \author definition, use a \RenewDocumentCommand and check whether the number of authors is 0, then redefine \AB@authors, then use the original \author inside.

\@maketitle sets the author and affil counter values to 0 at its end.
