Chapter redefinition

Question

For a system userguide, I have to follow a style guide.

This style guide imposes me to have :

• Chapters title in TOC without number neither word 'chapter' (in TOC and in the text)
• In the text I have to place a little symbol (marketing stuff) before the chapter name
• Section without the chapter number (I tryed \renewcommand{\thechapter}{} but the result on the section is :

.1 Section 1

.2 Section 2

I think I need to redefinine the chapter command (or create a new one) but I don't know how to do it.

Answer 1

One option using titlesec to change the chapter title formatting, titletoc to change the format for chapter entries in the ToC. \renewcommand\thesection{\arabic{section}} redefines the representation for the section counter to suppress the chapter counter. I used \S as the symbol before the chapter title but any other symbol can be used instead.

\documentclass{book}
\usepackage{titlesec,titletoc}

\titleformat{\chapter}[display]
  {\normalfont\huge\bfseries}{}{0pt}{\Huge\S}
\titleformat{name=\chapter,numberless}[display]
  {\normalfont\huge\bfseries}{}{0pt}{\Huge}
\titlecontents{chapter}
  [0pt]{\addvspace{10pt}\bfseries}{}{}
  {\hfill\contentspage}
\renewcommand\thesection{\arabic{section}}

\begin{document}

\tableofcontents
\chapter{Test chapter one}
\section{Test section one one}
\section{Test section one two}
\chapter{Test chapter two}
\section{Test section two one}
\section{Test section two two}

\end{document}
