[Tex/LaTex] Adding “\exists !” to the nomenclature

nomenclature

I get several errors on trying to add "\exists !" to the nomenclature.

Does someone can help?

Here my MWE (sorry for the makeindex, I don't want to change my build-command and without changing it, it completely fails)

\documentclass{article}
\usepackage{makeidx}
\usepackage{nomencl}

\makeindex

\makenomenclature

\begin{document}
dummy
\nomenclature{$\exists$}{exists}
%\nomenclature{$\exists !$}{exists exactly one} %error
%\nomenclature{$\exists!$}{exists exactly one} %error
\nomenclature{$\exists$!}{exists exactly one} %no effect

\printnomenclature
\end{document}

Solution:

\nomenclature{$\exists"!$}{exists exactly one}

Best Answer

Some characters are special for MakeIndex:

! @ | ( ) "

and they should be quoted when in an index entry; it doesn't matter whether it is \nomenclature, because it uses the same framework as \index. Quoting is obtained by prefixing the special character with ". Thus

\nomenclature{$\exists"!$}{exists exactly one}

should do.

[Tex/LaTex] Adding extra columns to the usnomencl nomenclature package

The usnomencl is a very simple nomenclature package that I have added to the University of Stellenbosch thesis (usthesis) bundle. It uses a list (description type) environment to set the nomenclature and would be difficult to add additional columns.

I would recommed a tabular type environment if you want more columns or a tabbing environment. Below is a proof of concept for a tabbing environment:

\documentclass{article}
\usepackage{sistyle} % or siunitx
\newcommand\bSI[1]{{\small[\SI{}{#1}]}}

\makeatletter
\newlength\unitwdth
\newlength\numwdth
\settowidth\unitwdth{\quad\bSI{m^3.kg^{-1}.s^{-2}}~}
\settowidth\numwdth{\quad 99}
\newlength\tdima
\newcommand\SIdescr[3]{%
    \setlength\tdima{\linewidth}%
    \addtolength\tdima{\@totalleftmargin}%
    \addtolength\tdima{-\dimen\@curtab}%
    \addtolength\tdima{-\unitwdth}%
    \addtolength\tdima{-\numwdth}%
    \parbox[t]{\tdima}{%
        #1
        \leaders\hbox{$\m@th\mkern \@dotsep mu\hbox{\tiny.}\mkern \@dotsep mu$}%
        \hfill
        \ifhmode\strut\fi
        \makebox[0pt][l]{%
            \makebox[\unitwdth][l]{\quad\bSI{#2}}%
            \makebox[\numwdth][l]{\quad #3}}}}
\makeatother

\begin{document}
\begin{tabbing}
    \parbox[t]{\linewidth}{\small      \hfill Pages\par              % Added
                                       \hfill where\par              % Added
                                 Symbol\hfill defined\par            % Added
                          \rule[.5\baselineskip]{\linewidth}{.5pt}}\\% Added

    \hspace*{1em}\=\hspace*{2em}\=\kill
    \>$x$ \> \SIdescr{coordinate in $x$ direction and a
             lot of other information to make it wrap}{m}{10}\\[1ex]
    \>$y$ \> \SIdescr{coordinate in $y$ direction}{m}{11}\\[1ex]

\end{tabbing}
\end{document}

[Tex/LaTex] Nomenclature duplicates

The nomencl package has a different purpose than what you're using it for.

The package's purpose is to write a list of symbols or abbreviation used, with a reference to the place where they're defined or first used (at the user's choice). So it's not meant to place multiple reference to a nomenclature.

For acronyms the best package around is glossaries, but the simpler acronym is often used.
