[Tex/LaTex] Customize \chaptermark for \mainmatter

fancyhdrheader-footersectioning

Hey guys it's me again,

I tried to add \leftmark to my header, but I want to change it from Chapter 1. Introduction to 1 Introduction. My MWE:

\documentclass[12pt, oneside, a4paper]{book}
\usepackage{titlesec}
\titleformat{\chapter}{\huge\bfseries}{\thechapter}{20pt}{\huge}
\usepackage{fancyhdr}
\fancypagestyle{plain}
{
    \fancyhf{}
    \fancyhead[L]{\rightmark}
    \fancyfoot[R]{\thepage}
    \renewcommand{\headrulewidth}{0.5pt}
    \renewcommand{\footrulewidth}{0pt}
}

\begin{document}
    \frontmatter
        \tableofcontents
    \mainmatter
        \chapter{Introduction}
        \chapter{Blablabla}
\end{document}

I googled a lot a found \renewcommand{\chaptermark}[1]{\markboth{#1}{}} and other variations and inserted it at different places of the preamble, but it doesn't work.

Am I missing something important again? Guess so, but I couldn't point it out.

\chaptermark can be redefined the following way:

\makeatletter
\if@twoside
  \renewcommand*{\chaptermark}[1]{%
    \markboth{%
      \ifnum\value{secnumdepth}>-1 %
        \thechapter\ %
      \fi
      #1%
    }{}%
  }%
\else
  \renewcommand*{\chaptermark}[1]{%
    \markright{%
      \ifnum\value{secnumdepth}>-1 %
        \if@mainmatter  
          \thechapter\ %
        \fi
      \fi
      #1%
    }%
  \fi
}
\makeatother

It prints the headers:

CONTENTS
1 Introduction
2 Blablabla

The upper casing of CONTENTS can be removed by the redefinition of \tableofcontents:

\usepackage{etoolbox}
\patchcmd{\tableofcontents}{\MakeUppercase\contentsname}{\contentsname}{}{}
\patchcmd{\tableofcontents}{\MakeUppercase\contentsname}{\contentsname}{}{}

That removed \MakeUppercase from the definition of \tableofcontents (twice).

[Tex/LaTex] Fancyhdr, chaptermark and table of contents

I still can't reproduce your problem as you've stated it. I'm now extrapolating what you might be trying to do: I'm assuming you're using a manual \markboth command for the table of contents, such as something similar to:

\tableofcontents
\markboth{Index}{}

and then the \markboth command only takes effect on the last page of the table of contents, as one can expect.

So, not sure now if I'm answering your question, but speculating: if you don't want the header to be upper cased, you can use the following code:

{
  \renewcommand{\MakeUppercase}[1]{#1}
  \tableofcontents
}

LaTeX uses \MakeUppercase when defining the marks for e.g. the table of contents (you can check in book.cls source), so the \renewcommand makes it now ineffective. The braces ensure that \MakeUppercase will continue to behave normally in the rest of the document.

Also, with the book document class, I get Contents in the header, not Index as you describe. If you want to change that, you can use

\renewcommand\contentsname{Index}

But I'd expect Index is usually rather used for a lookup index at the end of the book, with keywords and pages where those terms appear.

[Tex/LaTex] How to make pages after the first come out correctly with fancyhdr

If you don't set a proper head height, fancyhdr reports the following:

Package Fancyhdr Warning: \headheight is too small (XX.Xpt): 
 Make it at least YY.YYYYpt.
 We now make it that large for the rest of the document.
 This may cause the page layout to be inconsistent, however.

As such, the newly-set \headheight will be the same throughout the document. To avoid this, I've created the following minimal document that sets a consistent head height, adding a vertical space (gap) on the first page to simulate a larger header:

\end{document}

I've used geometry to adjust the page layout - it's just easier/more convenient.
