Layout for longer chapter title in Memoir class

Question

I am using \chapterstyle{section} with \Huge\sffamily font. This means that some longer chapter titles spread over two lines. I get (a larger version of!)

2 A long title splitting as illustrated here
over two lines

with the second line starting at the left margin, when I'd like the second line to be indented to start under the first word of the title.

This must be easy to effect (without cheating and putting in an \hspace!), but I'm not seeing how from the memoir manual.

Answer 1

It is not that simple. One might get by by using a hanging paragraph, here is another solution, which though has the disadvantage that one has to use \newline to force a line break

\documentclass[a4paper]{memoir}
\usepackage{calc}
\makechapterstyle{section}{%
  \chapterstyle{default}
  \renewcommand{\printchaptername}{}
  \renewcommand{\chapternamenum}{}
  \renewcommand{\chapnumfont}{\normalfont\Huge\bfseries}
  \renewcommand{\printchapternum}{}%\chapnumfont \thechapter\space}
  \renewcommand{\afterchapternum}{}
  \renewcommand\printchaptertitle[1]{%
    \begin{tabular}{@{} p{1cm} >{\raggedright\arraybackslash}p{\textwidth-1cm}}
      \chapnumfont\thechapter & \chaptitlefont ##1
    \end{tabular}
  }
}
\chapterstyle{section}
\begin{document}
\chapter{Some very long title that hopefully span two lines}
\end{document}

Edit: Looking though the memoir sources, it turns out this is very easy, have a look at the reparticle style, so this is enough

\makeatletter
\makechapterstyle{section}{%
  \chapterstyle{default}
  \renewcommand{\printchaptername}{}
  \renewcommand{\chapternamenum}{}
  \renewcommand{\chapnumfont}{\normalfont\Huge\bfseries}
  \renewcommand{\printchapternum}{}%\chapnumfont \thechapter\space}
  \renewcommand{\afterchapternum}{}
  \renewcommand*{\printchapternum}{%
       \@hangfrom{\chapnumfont \thechapter\quad}}%
}
\makeatother
