Setting the header to include only the page number, chapter #, and chapter title (in memoir)

Question

I want to set the header with the page number and the chapter number on the even pages and the chapter title and the page number on the odd pages. That is, as is shown in this image:

Here is as far as I've gotten. This gives me the chapter title in the right place, but not the chapter number.

\documentclass[10pt]{memoir}
\usepackage{lipsum}

\makepagestyle{myheadings}
\makepsmarks {myheadings}{
\nouppercaseheads
\createmark {chapter} {left} {nonumber}{\@chapapp\ }{. \ }
%\createmark {chapter} {right} {notitle}{\@chapapp\ }{ }

\createplainmark {toc} {both} {\contentsname}
\createplainmark {lof} {both} {\listfigurename}
\createplainmark {lot} {both} {\listtablename}
\createplainmark {bib} {both} {\bibname}
\createplainmark {index} {both} {\indexname}
\createplainmark {glossary} {both} {\glossaryname}
}
\makeoddhead{myheadings}{\footnotesize\sffamily\leftmark}{}{\footnotesize\sffamily\thepage}
\makeevenhead{myheadings}{\footnotesize\sffamily\thepage}{}{\footnotesize\sffamily\rightmark}
\pagestyle{myheadings}

\begin{document}
\chapter{Chapter title}
\section{Introduction}
\lipsum[1-5]
\section{Section title}
\lipsum[6-10]
\end{document}

I have been trying to include something like this: \createmark {chapter} {right} {notitle}{\@chapapp\ }{ }, but that hasn't worked.

I've also tried \makeevenhead{myheadings}{\footnotesize\sffamily\thepage}{}{\footnotesize\sffamily{Chapter~\thechapter}}. That works for most of the book, but not for the toc, preface, and appendices (which become Chapter 0, Chapter A, and Chapter B in the header).

Answer 1

Here's how I'd solve it

\documentclass[10pt]{memoir}
\usepackage{lipsum}
\makeatletter
\makepagestyle{myheadings}
\makepsmarks{myheadings}{
  \nouppercaseheads
  % remove any marks for sections (might be left over from default pagestyle)
  \clearmark{section}
  \clearmark{subsection}
  \clearmark{subsubsection}
  % hand code \chaptermark, the code is taken from the definition of
  % \createmark for the 'both' version, and cleaned a little
  \renewcommand\chaptermark[1]{
    \@setclcnt{chapter}{@memmarkcntra}%
    \advance\c@@memmarkcntra\m@ne
    \markboth{%
      \memUChead{%
        \ifnum\c@secnumdepth > \c@@memmarkcntra
          \if@mainmatter
            \@chapapp\ \thechapter
          \fi
        \fi
      }%
    }{%
      \memUChead{%
        ##1%
      }%
    }%
  }%
  \createplainmark{toc}     {both}{\contentsname}
  \createplainmark{lof}     {both}{\listfigurename}
  \createplainmark{lot}     {both}{\listtablename}
  \createplainmark{bib}     {both}{\bibname}
  \createplainmark{index}   {both}{\indexname}
  \createplainmark{glossary}{both}{\glossaryname}
}
\makeatother
\makeoddhead{myheadings}{\footnotesize\sffamily\rightmark}{}{\footnotesize\sffamily\thepage}
\makeevenhead{myheadings}{\footnotesize\sffamily\thepage}{}{\footnotesize\sffamily\leftmark}
\pagestyle{myheadings}

\begin{document}
\chapter{Chapter title}
\section{Introduction}
\lipsum[1-5]
\section{Section title}
\lipsum[6-10]
\end{document}
