# Hiding chapter headings and including chapter name in section headings

I would like chapter names to not be printed but to appear in each section heading. For example:

\chapter{Mychapter}
\section{}
\blinddocument
\section{}


Would print something like

Mychapter 1
Mychapter 2


How can I achieve that? I've tried titlesec with \chaptertitle in \titleformat, like:

\titleformat{\section}[display]
{\normalfont\Large}
{\chaptertitle\ \thesection}{10pt}
{\normalfont}


but \chaptertitle seems to be only defined inside \sethead and \setfoot.

To hide chapters and number sections properly, I've used:

\renewcommand{\thechapter}{}
\renewcommand{\thesection}{\arabic{section}}


but I'm sure there must be something better...

-

Try the following. It would not work for all the options of memoir, because it has two optional arguments for the \chapter command.

\documentclass{book}

\makeatletter
\let\oldchapter\chapter

\renewcommand\chapter{%
\@afterindentfalse
\secdef\@mychapter\@schapter}

\def\@mychapter[#1]#2{%
\chaptermark{#1}%

\def\chaptermark#1{%
\markboth {\MakeUppercase{#1}}{}}%

\def\sectionmark#1{%
\markright{\MakeUppercase{%
\ifnum \c@secnumdepth >\z@
\arabic{section}. \ %
\fi
#1}}}


Thank you. This does what I am looking for as far as sections go, but it doesn't hide the chapter headings. How would I make it so that chapter headings don't appear in the document? I guess I could do a \renewcommand{\chapter}{something to adapt chapter} ? – ℝaphink Apr 11 '11 at 8:47
@Raphink: I have changed the code to retain the \chapter* command and chapter marks, but has removed the normal chapter heading. Note that the table of contents (if you are using it) is now a mess and also needs some redefinitions – Danie Els Apr 11 '11 at 9:57
