fancyhdrheader-footer
How can I set different header for different sections. In this example I am looking for replacement of \SomeCommand
\documentclass{article}
\begin{document}
\SomeCommand{Header 1 define here} %this sets header for all pages until another \SomeCommand found
This is multi-page text
\newpage
\SomeCommand{Header 2 define here} %this changes the header to new
This is multi-page text
\end{document}
My document is NOT arranged in \section and not a book. It is just plane text.
It would be better not to use the package fancyhdr with KOMA classes like scrreprt.
One of the dedicated packages scrpage2 or scrpage-scrlayer should be used instead.
In your case, it suffices to load the latter and use the page style scrheadings with the following modifications:
\renewcommand*\chaptermarkformat{\thechapter\autodot\enskip}
\automark[chapter]{chapter}
The first line is to eliminate the word "Chapter" from the header and the latter is to place the chapter mark both in even and odd pages.
If you don't want chapter numbers replace the first line with
\renewcommand*\chaptermarkformat{}
MWE:
\documentclass[twoside,openright,chapterprefix=true]{scrreprt}
\usepackage{lipsum} % only for the example
\usepackage{scrlayer-scrpage}
\renewcommand*\chaptermarkformat{\thechapter\autodot\enskip}
\automark[chapter]{chapter}
\pagestyle{scrheadings}
\begin{document}
\chapter{Test}
\lipsum[1-5]
\section{A section}
\lipsum[1-5]
\end{document}
Output:
If you want the header line load scrlayer-scrpage with the option headsepline:
\usepackage[headsepline]{scrlayer-scrpage}
Instead, if you want to swap the sides where headers are printed, you have to define an own style, like this:
\defpagestyle{mystyle}{%
{\hfill\headmark}{\headmark\hfill}{\hfill}
}{%
{\hfill}{\hfill}{\hfill}
}
and use \pagestyle{mystyle} instead of \pagestyle{scrheadings}.

\documentclass[twoside,openright,chapterprefix=true]{scrreprt}
\usepackage{lipsum} % only for the example
\usepackage{scrlayer-scrpage}
\renewcommand*\chaptermarkformat{\thechapter\autodot\enskip}
\automark[chapter]{chapter}
\defpagestyle{mystyle}{%
{\hfill\headmark}{\headmark\hfill}{\hfill}
}{%
{\hfill}{\hfill}{\hfill}
}
\pagestyle{mystyle}
\begin{document}
\chapter{Test}
\lipsum[1-5]
\section{A section}
\lipsum[1-5]
\end{document}
Output:
Use \leftmark in the header. There is also a \rightmark. However, here in book-class, with default options, \leftmark would hold the chapter-name, with some formatting. This can be changed of course.
A few places throughout your document, you need to change what is in the header, as you haven't yet defined a non-starred \chapter. Then we can update \rightmark with \markkright, but there is no \markleft-command available. A shame really, could be useful. \markboth{left}{right} could be used here, though.
\pagestyle for when you want a single page to be different. Use \thispagestyle, which only changes the style for that one page. Have the first/main \pagestyle in the preamble, keeps it a bit tidier. Content and settings should in my opinion be separated as much as possible.\clearpages. In book-class, the default option is openright, which means that every chapter will start at only right-hand sides.Code
\documentclass[12pt, a4paper]{book}
\usepackage{tocbibind}
\usepackage{lipsum}
\usepackage{emptypage}
%%%%% Header
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[CE]{Me}
\fancyhead[CO]{\leftmark}
\fancyfoot[CE,CO]{\thepage}
\renewcommand{\headrulewidth}{0pt}
\pagestyle{fancy}
\begin{document}
\thispagestyle{empty}
{\renewcommand\addcontentsline[3]{}
\tableofcontents}
\clearpage
\chapter*{Introduction}\markboth{Introduction}{}
\lipsum[1-9]
\clearpage
\part{Thing} \markboth{Part thing}{}
\lipsum[1-10]
\chapter{Thing thing}
\lipsum[1-7]
\chapter{thingthingthing}
\lipsum[1-8]
\end{document}
Best Answer
If there are no special layout requirements you can use the pagestyle
myheadings. Then\SomeCommandhas to set\markright{<text>}or maybe better\markboth{<text>}{<text>}. The second works also if your document istwoside.
