using \include for unnumberred chapters and sections ->tableofcontent mess?

Question

I want to have a document with the following preconditions:

• sections in separate files -> \include{}

• chapters and sections are unnumbered -> using \addchap{} and \addsec{}

• chapter headings should only appear in tableofcontents

For the not appearing chapter headings I adopted and modified a brilliant solution by user egreg:

Chapter without heading

Removing any one of the preconditions gives a sensible table of contents. All three make a mess. It's like a reverse borromean ring. My main document looks something like this:

\documentclass[english, a4paper, 12pt]{scrbook}
\usepackage[english]{babel}
\usepackage{blindtext}      


\begin{document}
\makeatletter
 \newcommand\nochap[1]{%
  \begingroup
  \let\@makeschapterhead\@gobble % make \@makechapterhead do nothing
  \addchap{#1}
  \endgroup
  }
\makeatother

\tableofcontents

\nochap{That'n'those}
\include{alottatext}
\include{alottamoretext}
\end{document}

with alottatext looking like:

\addsec{alottatext}
\blindtext

With this option the table of contents looks like:

alottatext

That'n'Those

alottamoretext

whereas the expected result would've been:

That'n'Those

alottatext

alottamoretext

So it always moves the Chapter one position down. hyperref would still work right.

I know it's quite a puzzle but maybe anyone can help getting the order right.

Answer 1

If you are using KOMA-Script version 3.17 or older you have to replace \include{...} by \clearpage\input{...}. If you do not want that the content of the loaded file starts on a new page then use only \input{...}.

With KOMA-Script version 3.18 or newer there is no problem with the order of the TOC entries. But the code that removes the chapter heading does not work anymore. So you have to change the defintion of \nochap to

\newcommand\nochap[1]{%
  \cleardoublepage
  \addchaptertocentry{}{#1}%
}

Note that this code also works with older KOMA-Script versions.

\begin{filecontents*}{alottatext.tex}
\addsec{alottatext}
\blindtext
\end{filecontents*}

\begin{filecontents*}{alottamoretext.tex}
\addsec{alottamoretext}
\blindtext
\end{filecontents*}

\documentclass[english, a4paper, 12pt]{scrbook}
\usepackage[english]{babel}
\usepackage{blindtext}

\newcommand\nochap[1]{%
  \cleardoublepage
  \addchaptertocentry{}{#1}%
}

\begin{document}
\tableofcontents
\nochap{That'n'those}

\clearpage\input{alottatext}

\clearpage\input{alottamoretext}
\end{document}

---

To ensure that it works with hyperref use \phantomsection in the definition of \nochap:

\newcommand\nochap[1]{%
  \cleardoublepage
  \ifundefinedorrelax{phantomsection}{}{\phantomsection}%
  \addchaptertocentry{}{#1}%
}

Example (without \clearpage before \input):

\begin{filecontents*}{alottatext.tex}
\addsec{alottatext}
\Blindtext[10]
\end{filecontents*}

\begin{filecontents*}{alottamoretext.tex}
\addsec{alottamoretext}
\Blindtext[10]
\end{filecontents*}

\documentclass[english, a4paper, 12pt]{scrbook}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{hyperref}

\newcommand\nochap[1]{%
  \cleardoublepage
  \ifundefinedorrelax{phantomsection}{}{\phantomsection}%
  \addchaptertocentry{}{#1}%
}

\begin{document}
\tableofcontents
\nochap{That'n'those}

\input{alottatext}
\input{alottamoretext}
\end{document}
