I have an article divided into sections and subsections. I need to insert a subsection "5.2a" between "5.2" and "5.3". What is the easiest way to do this?

Hi, you can find the answer to your question in this topic stackoverflow.com/questions/2839647/…. Only small adaptation would be required to get the result you want.– MythioMar 22, 2013 at 12:27

I removed the sections-paragraphs tag because your question could also be useful for modifying chapter numbers.– lockstepMar 22, 2013 at 12:59

If it is just for just one time, the easies way would be to redefine the representation for the subsection counter, and then revert to the original definition:
\documentclass{article}
\begin{document}
\section{Test Section}
\subsection{Test Subsection One}
\addtocounter{subsection}{-1}
\renewcommand\thesubsection{\thesection.\arabic{subsection}a}
\subsection{Test Subsection One A}\label{sec:test}
\renewcommand\thesubsection{\thesection.\arabic{subsection}}
\subsection{Test Subsection Two}
\end{document}
-
instead of re-resetting after the changed
subsection
, one could precede the initial\addtocounter
by\begingroup
and replace the second\renewcommand\thesubsection
by\endgroup
. the changed heading will go into the table of contents. (and yes, i know these are "plain" tex commands, not latex, but they're more visible than braces, which could also be used.) Mar 22, 2013 at 13:52 -
Thanks, as this is a one-off I think I'll go for the quick and dirty solution!– ajdMar 23, 2013 at 5:51
A more general solution is to do the redefinition without any assumption about what \thesubsection
expands to.
\documentclass{article}
%\usepackage{hyperref} % uncomment for testing with it
\makeatletter
\newcommand{\specialsubsection}[1]{%
\def\@specialsubsectionsuffix{#1}%
\@dblarg\@specialsubsection
}
\def\@specialsubsection[#1]#2{%
\begingroup
\expandafter\def\expandafter\thesubsection\expandafter{%
\thesubsection\@specialsubsectionsuffix}%
\@ifundefined{theHsubsection}%
{}%
{\expandafter\def\expandafter\theHsubsection\expandafter{%
\theHsubsection\@specialsubsectionsuffix}}%
\addtocounter{subsection}{-1}%
\subsection[#1]{#2}%
\endgroup
}
\makeatother
\begin{document}
\section{Test Section}
\subsection{Test Subsection One}
\specialsubsection{a}{Test Subsection One A}\label{sec:test}
\specialsubsection{b}[For toc]{Test Subsection One B}
\subsection{Test Subsection Two}
\end{document}
This allows also for a different TOC entry, with the usual optional argument (after the suffix).
The \theHsubsection
bit is to make the code work with hyperref
.
