Page Layout ⇒ Period after section number

[ditrans]

Hello everyone,

could someone please tell me how I can put a period after section numbers (without then having two periods between a section and a subsection number)?

Thanks!!

Hi,

for the standard document classes you can use the titlesec package. Take a look at the following example:

Code: Select all

\documentclass{article}
\usepackage{titlesec}

\titleformat{\section}
  {\normalfont\Large\bfseries}{\thesection.}{1em}{}

\begin{document}

\section{Test section}
\subsection{Test subsection}

\end{document}

Addendum: of course, my previous response will place a period after section numbers only (as originally requested). If the period must appear after every sectional unit (from sections down), then a redefinition of \@seccntformat would be a better choice:

Code: Select all

\documentclass{article}

\makeatletter
  \renewcommand\@seccntformat[1]{\csname the#1\endcsname.\quad}
\makeatother

\begin{document}

\section{Test section}
\subsection{Test subsection}
\subsubsection{Test subsubsection}

\end{document}

In fact, the previous code can be modified to allow the period to appear only on certain sectional units (without using additional packages); the following example code will produce a perior after the section and subsubsection numbers, but not after the subsection numbers:

Code: Select all

\documentclass{article}

\makeatletter
  \renewcommand\@seccntformat[1]{%
    \@ifundefined{#1@cntformat}%
    {\csname the#1\endcsname\quad}%
    {\csname #1@cntformat\endcsname}}
  \newcommand\section@cntformat{\thesection.\quad}
  \newcommand\subsubsection@cntformat{\thesubsubsection.\quad}
\makeatother

\begin{document}

\section{Test section}
\subsection{Test subsection}
\subsubsection{Test subsubsection}

\end{document}

Thank you a lot for your indepth response. I tried your first solution and just added commands for subsection etc., but your second solution seems cleaner so I think I'll use that.

Thanks again!
