[Tex/LaTex] Is it possible to change the appearance of a \ref

cross-referencingpunctuationsectioning

I am using article class, and by default, the numbers of the sections, subsections appear like 1 section, 2 section in time I want them to appear like 1. section, 2. section (with dots).

I have redefined the format of my section, subsection, etc. as follows:

\renewcommand\thesection{\arabic{section}.}
\renewcommand\thesubsection{\arabic{section}.\arabic{subsection}.}

because I wanted . after the number of the section and the subsection. Fortunately, I got the format that I want, but now I have another problem, when I use the cross-reference to the section or the subsection, I got extra . after the reference, like: as we have seen in section 1.., or section 2.. it is unwanted. How can I get rid of this extra .? Is there anyway to change or redefine the appearance of the \ref?

My answer to can i change refs output can be adjusted for this:

\documentclass{article}

\renewcommand\thesection{\arabic{section}.}
\renewcommand\thesubsection{\thesection\arabic{subsection}.}
\renewcommand\thesubsubsection{\thesubsection\arabic{subsubsection}.}

\makeatletter
\renewcommand{\p@section}{\arabic{section}\expandafter\@gobble}
\renewcommand{\p@subsection}{\thesection\arabic{subsection}\expandafter\@gobble}
\renewcommand{\p@subsubsection}{\thesubsection\arabic{subsubsection}\expandafter\@gobble}
\makeatother

\begin{document}

\section{test}\label{test}
\subsection{subtest}\label{subtest}
\subsubsection{subsubtest}\label{subsubtest}


See section~\ref{test} and subsection~\ref{subtest} and subsubsection~\ref{subsubtest}!

\end{document}

Note that this is a little bit of a hack.

You could also adjust the sectioning commands using titlesec instead.

[Tex/LaTex] How to make \ref display only subsection

A \label to some counter like subsection is normally constructed as \p@subsection\thesubsection . In most cases the "prefix" command \p@... doesn't typeset anything and thus the result is the same what is produced by \the.... Such "prefix" commands are only used by the standard classes to construct references like 1.a in enumerations when the items there are labeled 1 and the subitem a.

The revtex4.cls however is using the \p@...commands also for heading counters:

\def\thesection       {\Roman{section}}
\def\p@section        {}
\def\thesubsection    {\Alph{subsection}}
\def\p@subsection     {\thesection\,}
\def\thesubsubsection {\arabic{subsubsection}}
\def\p@subsubsection  {\thesection\,\thesubsection\,}

So if you change \thesubsection as you did you end up with the following:

\thesection\,\thesection.\arabic{subsection}

In other words you need to also change all the corresponding \p@...commands to expand to nothing. I the document preamble place:

\makeatletter
\def\p@subsection{}
\makeatother

[Tex/LaTex] Remove period when cross-referencing a section

The class does \renewcommand\thesection {\@arabic\c@section.} and this is causing the undesired period in cross-references; this seems a bad design choice by the class author. If you want to avoid this, you can redefine \thesection to suppress the period and then you need to make some changes to \thesubsection, to the section entries in the ToC and to the section headings:

\documentclass[12pt]{IET02}

\usepackage{tocloft}
\usepackage{titlesec}
\titleformat{\section}
  {\normalfont\bfseries}{\thesection.}{0.5em}{}
\renewcommand\cftsecaftersnum{.} 
\renewcommand\thesection{\arabic{section}}
\renewcommand\thesubsection{\thesection.\arabic{subsection}}

\begin{document} 
\tableofcontents
\section{Introduction}
This is the introduction, Section \ref{sec:methods} is the methods section. Some conclusions are given in Section \ref{sec:conclusions}.

\section{Methods}\label{sec:methods}
This is the methods section. Section \ref{sec:method1} discusses the first result.

\subsection{Method 1}\label{sec:method1}
This is method 1.

\section{Conclusions}\label{sec:conclusions}
Something profound.

\end{document}

I don't know however if you are allowed to use these packages. You should inform the conference organizers about this problem with the class.
