I am using Journal in the Paper environment but need to change format of \JournalContents. How do I do this?

Question

This is my main.tex document

\documentclass[journal,12pt]{paper}
\begin{document}
\journalcontents
\include{./paper_1}
\end{document}

The paper_1.tex document is as follows

\title{Title}
\subtitle{Subtitle}
\author{Author name}
\shorttitle{Short title}
\shortauthor{Short author name}
\maketitle

The problem is that the \journalcontents macro prints the Short author name in bold and dots to the page number, and then on the next line it shows the short title for paper 1 and any other papers I include.This is shown here

What I want is for the \journalcontents to print the Shorttitle then the dots to the line number with the Subtitle on the next line which can be multiple lines.

How do I edit the \journalcontents macro to do this ?

Answer 1

I am not sure if this is what you want. Because I am not familiar with the paper document. However by checking the source code, the \journalcontents entries are added though \maketitle command. You could patch the \maketitle command to have extra subtitle entry after the short title. I assume you want it to use the full text width and without any indent.

\documentclass[journal,12pt]{paper}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\maketitle}{\if@twoside}{\addtocontents{jou}{\noindent\@subtitle\par}\if@twoside}{}{}
\makeatother

\begin{document}
\journalcontents
\title{Title}
\subtitle{A super super super super super super super super super super super super super super super super super super super super super super super super Subtitle}
\author{Author name}
\shorttitle{Short title}
\shortauthor{Short author name}
\maketitle
\end{document}
