General ⇒ [glossaries] output depending on definition of a userkey

[redted]

edited:Added minimal example and desired output vs generated output

Hi,
since i have not found a more suiting subforum i'll post this in general.

I use the glossaries package and would like to have different output in the glossarie depending on wether the user1-key (key the package provides as options for the entries) has been defined or not.

I am trying to do this by putting the following into a style definition (for a tabular style thats why there are ampersands and double backslashes):

Code: Select all

\renewcommand*{\glossaryentryfield}[5]{\bfseries{\glstarget{##1}{##2}} & ##3 \\
\ifempty{\glsentryuseri{##1}}
    it & is very empty \\
\else
    & \glsentryuseri{##1} \\%
\fi}

which however results in the following error(s):

Code: Select all

! Undefined control sequence. \ifempty l.49 \setentrycounter{page}\glsnumberformat{a}}} % The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., \hobx'), typeI' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined.

I assume it has something to do with the order of the expansion/evaluation.

Greetings ted

Minimal example (almost), the part with "\renewcommand*{\glossaryentryfield}" is the important one:

Code: Select all

\documentclass{scrreprt}
\usepackage[latin1]{inputenc}
\usepackage[toc,nomain]{glossaries}
\newglossarystyle{acronymAndExplanation}{%
\glossarystyle{long}
% put the glossary in a longtable environment:
\renewenvironment{theglossary}{\begin{longtable}{lp{\glsdescwidth}}}{\end{longtable}}%
\renewcommand*{\glossaryheader}{}%
\renewcommand*{\glsgroupheading}[1]{}%
\renewcommand*{\glossaryentryfield}[5]{\bfseries{\glstarget{##1}{##2}} & ##3 \\
\ifempty{\glsentryuseri{##1}}
	it & is very empty \\
\else
& \glsentryuseri{##1} \\%
\fi
}
\renewcommand*{\glossarysubentryfield}[6]{\glossaryentryfield{##2}{##3}{##4}{##5}{##6}}%
\renewcommand*{\glsgroupskip}{& \\}%
}

\newglossary[abkuerzungen]{abk}{abkin}{abkout}{Abkürzungsverzeichnis}
\makeglossaries

\newacronym[type=abk]{abc}{abc}{Alphabet}
\newacronym[type=abk,user1={my longer description}]{abba}{abba}{Band}

\glsaddall

\begin{document}

\printglossary[type=abk,nonumberlist,style=acronymAndExplanation]

\begin{longtable}{lp{\glsdescwidth}}
\bfseries{abba} & Band \\
 & my longer description \\
\bfseries{abc} & Alphabet \\
\end{longtable}

\end{document}

\ifempty isn't defined in standard LaTeX, which is what's causing the error message. You can use the ifmtarg package, which provides the internal command \@ifmtarg. For example:

Code: Select all

\documentclass{article}

\usepackage{ifmtarg}
\usepackage[style=long]{glossaries}

\makeglossaries

\makeatletter
\newcommand*{\ifuseriempty}[3]{%
  \protected@edef\tmp{\glsentryuseri{#1}}%
  \expandafter\@ifmtarg\expandafter{\tmp}{#2}{#3}%
}
\makeatother

\renewcommand*{\glossaryentryfield}[5]{\bfseries{\glstarget{#1}{#2}}
& #3 \\
\ifuseriempty{#1}%
  {it &is very empty}%
  { &\glsentryuseri{#1}}%
\\%
}

\newglossaryentry{sample}{name=sample,%
  description={sample without user 1 key}}

\newglossaryentry{sample2}{name=sample2,%
  description={sample with user 1 key},
  user1={User1 Value}}

\begin{document}
\gls{sample}, \gls{sample2}.

\printglossaries
\end{document}

Thank you very much Nicola, the solution works just fine. I stumbled briefly over the fact that i have to use two '#' instead of one '#' if I want too use that in the definition of a new \newglossarystyle enviornment

For my purposes the glossaryentryfield has to look like this:

Code: Select all

\renewcommand*{\glossaryentryfield}[5]{\bfseries{\glstarget{#1}{#2}}
& #3 \\
\ifuseriempty{#1}%
  {}%
  { &\glsentryuseri{#1}\\}%
}

thus only creating rows if the field has been defined.

Thanks again ted

Struggling with exactly the same problem. However, the example by Nicola Talbot gives me a single line of output, with just "sample, sample2." Is this supposed to be a working example?
