[Tex/LaTex] scrbook – How to place chapter to the left edge and section to the right edge on single-sided (!) documents

header-footerkoma-script

Let's create a single-sided (!) document made in scrbook-class (e.g. scientific work) by setting \documentclass[twoside=false]{scrbook}.

Working minimum-example:

\documentclass[twoside=false]{scrbook}

\usepackage{blindtext}

\begin{document}

    \blinddocument

\end{document}

Consequently, the chapter will be placed in the middle of the head (on non-plain-pages).

But now how is it possible to place the chapters name to the left edge and the sections name to the right edge?

In a two-sided layout it would be really simple by typing…

\automark[section]{chapter}       % chapter in \leftmark; section in \rightmark

\lehead[]{\leftmark}{\leftmark}   % \leftmark placed in even-side left-edges
\rohead{\rightmark}               % \rightmark placed in odd-side right-edges

… into the preambel. But how does it work for single-sided documents (with declaration twoside=false)?

It is a well known fact that popular KOMA-classes like…

\lehead[content plain.scrheadings]{content scrheadings}
\rehead[content plain.scrheadings]{content scrheadings}

… only will work fine in double-sided layouts.

Thank you very much for your help, I'm curious about your solutions! 🙂

Best Answer

If you want to use both \leftmark and \rightmark in a one-sided document with package scrlayer-scrpage you have to set the option autooneside=false

\documentclass[twoside=false]{scrbook}
\usepackage{blindtext}

\usepackage[
  automark,
  autooneside=false % <- 
]{scrlayer-scrpage}
\clearpairofpagestyles
\ihead{\leftmark}
\ohead{\rightmark}
\cfoot*{\pagemark}

\begin{document}
\blinddocument
\end{document}

enter image description here

Note that option automark does the same as \automark[section]{chapter} and \cfoot*{\pagemark} is a short version of \cfoot[\pagemark]{\pagemark}.

Update

To avoid identical entries in left and right header you can change the definition of \ohead to 

\ohead{\ifstr{\rightmark}{\leftmark}{}{\rightmark}}

enter image description here

Code:

\documentclass[twoside=false]{scrbook}
\usepackage{blindtext}
\usepackage[
  automark,
  autooneside=false 
]{scrlayer-scrpage}
\clearpairofpagestyles
\ihead{\leftmark}
\ohead{\ifstr{\rightmark}{\leftmark}{}{\rightmark}}
\cfoot*{\pagemark}

\begin{document}
\blinddocument
\chapter{Chapter}
\Blindtext
\end{document}
