[Tex/LaTex] glossaries: list of symbols, first appearence in text

acronymsglossariesliststext;

I followed this answer to add a seperate list of symbols, besides my acronym list and general glossary:
glossaries: How to customize list of symbols with additional column for units?

As a first appearence in text I would like to see Absolute Humidity (AH), and the next appearences only AH, but when I add

    first={Absolute Humidity (AH)}

to the code, it just ignores it. Adding text={Absolute Humidity (AH)} works, but then all my references are in this long variant. I refer to it as in the code below in my main.tex

\documentclass[a4paper,10pt,twoside]{report}
\usepackage[acronym,nopostdot,toc,section=chapter]{glossaries}
\newglossary[slg]{symbolslist}{syi}{syg}{Symbolslist} % create symbolslist
% Glossary settings
\glsaddkey{unit}{\glsentrytext{\glslabel}}{\glsentryunit}{\GLsentryunit}{\glsunit}{\Glsunit}{\GLSunit}
\makeglossaries
\loadglsentries{glossary}
\newglossarystyle{symbunitlong}{%
\setglossarystyle{long3col}% base this style on the list style
\renewenvironment{theglossary}{% Change the table type --> 3 columns
    \begin{longtable}{p{2cm}p{10.92cm}p{2cm}}}%
    {\end{longtable}}%
\renewcommand*{\glossaryheader}{%  Change the table header
    \bfseries Sign & \bfseries Description & \bfseries Unit \\
    \hline
    \endhead}
\renewcommand*{\glossentry}[2]{%  Change the displayed items
    \glstarget{##1}{\glossentryname{##1}} %
    & \glossentrydesc{##1}% Description
    & \glsunit{##1}  \tabularnewline
    }
}

\begin{document}
In text reference of first appearance of the term \gls{AH}, second appearence \gls{AH}.
    %Print the glossary
    \glsaddall
    %\printglossaries % print all in default values
    \printglossary[type=\acronymtype, style=list, nonumberlist] % prints just the list of acronyms
    \printglossary[type=symbolslist, style=symbunitlong]   % list of symbols
    \printglossary[style=altlist,nonumberlist ] % if no option is supplied the default glossary is printed.

\end{document}

my glossay.tex file looks like this

    \newglossaryentry{AH}{type=symbolslist,
    name={AH},
    description={Absolute Humidity.},
    unit={$g/m^3$}}

How can I solve this?

Best Answer

This is the simplest method (given that AH is essentially an abbreviation):

\documentclass[a4paper,10pt,twoside]{report}

\usepackage[acronym,nopostdot,toc,section=chapter,acronymlists={acronym,symbolslist}]{glossaries}

\newglossary[slg]{symbolslist}{syi}{syg}{Symbolslist} % create symbolslist

% Glossary settings

\glsaddkey{unit}{\glsentrytext{\glslabel}}{\glsentryunit}{\GLsentryunit}{\glsunit}{\Glsunit}{\GLSunit}

\makeglossaries

\setacronymstyle{long-short}

\newglossarystyle{symbunitlong}{%
\setglossarystyle{long3col}% base this style on the list style
\renewenvironment{theglossary}{% Change the table type --> 3 columns
    \begin{longtable}{p{2cm}p{10.92cm}p{2cm}}}%
    {\end{longtable}}%
\renewcommand*{\glossaryheader}{%  Change the table header
    \bfseries Sign & \bfseries Description & \bfseries Unit \\
    \hline
    \endhead}
\renewcommand*{\glossentry}[2]{%  Change the displayed items
    \glstarget{##1}{\glossentryname{##1}} %
    & \glossentrydesc{##1}% Description
    & \glsunit{##1}  \tabularnewline
    }
}

\newacronym[type=symbolslist,unit={$g/m^3$}]{AH}{AH}{Absolute Humidity}


\begin{document}
In text reference of first appearance of the term \gls{AH}, second
appearence \gls{AH}.

    %Print the glossary

    \glsaddall
    %\printglossaries % print all in default values
    \printglossary[type=\acronymtype, style=list, nonumberlist] % prints just the list of acronyms
    \printglossary[type=symbolslist, style=symbunitlong]   % list of symbols
    \printglossary[style=altlist,nonumberlist ] % if no option is supplied the default glossary is printed.

[Tex/LaTex] Manually set first-use flag using glossaries

The package glossaries defines a boolean flag for every entry. If you call \ac the boolean flag is set to true. That means next time you know that the entry was used.

To set this flag manual the package provides the command \glsunset.

The documentation describes the command at page 105 (glossaries-user.pdf).

When using \gls, \glspl and their uppercase variants it is possible that you may want to use the value given by the first key, even though you have already used the glossary entry. Conversely, you may want to use the value given by the text key, even though you haven’t used the glossary entry. The former can be achieved by one of the following commands:

...

while the latter can be achieved by one of the following commands:
\glsunset{⟨label⟩}

Related to your example do:

\documentclass{scrreprt}

\usepackage[xindy, shortcuts]{glossaries}

\newacronym{TA}{TA}{Test Acronym}
    \makeglossaries

\begin{document}

\printglossary[type=\acronymtype]

\begin{description}
    \item[\acf{TA}\glsunset{TA}] This is an explanation of the item…
         The first use flag should be set after this!
         But it does!, and will display Test Acronym (TA) again… Which is not intended!
\end{description}

When using \ac{TA} here like this, it should not reproduce the entire entry again.

\printglossary

[Tex/LaTex] Glossaries : list only page number of the first occurrence

I suspect the reason why this question has remained unanswered for two years is because it's actually more than one question which doesn't fit in with the way this site works, but it needs to be either answered or closed to get it off the unanswered list.

Your first question (and the question title) you have already answered in a comment. The package option indexonlyfirst will only add the first use to the location list.

MWE:

\documentclass{article}

\usepackage[nopostdot,% remove dot after description
  indexonlyfirst,% only index first use
  nomain,acronym,xindy,toc,numberline]{glossaries}

\makeglossaries

\newacronym{MC}{MC}{Monte Carlo}
\newacronym{L}{L}{bond length}

\begin{document}

\printglossaries

\newpage
This is the first use of \gls{MC}.
\newpage
This is the first use of \gls{L}.
\newpage
This is the second use of \gls{MC}.
\newpage
This is the second use of \gls{L}.

\end{document}

Your second question (which really ought to be a separate post) is a little confusing.

For all the comumns, I need to add column names:

Symbol ....... Name and Units ....... First used on Page No.

The dots means white space.

This suggests a 3-column tabular layout, but your example code has six columns. Assuming that you're storing the unit in the user1 field and by "Symbol" you mean the short form (such as L) and by "Name" you mean the long form (such as bond length) then the following will produce a three column style (I've just used \AA for the ångström sign for simplicity, but it would be better to use siunitx to deal with the units):

\documentclass{article}

\usepackage[nopostdot,% remove dot after description
  indexonlyfirst,% only index first use
  nomain,acronym,xindy,toc,numberline]{glossaries}

\makeglossaries

\newacronym[user1={\AA}]{L}{L}{bond length}

\newglossarystyle{myunitstyle}{%
 \setglossarystyle{long3col}% base it on the long3col style
  \renewenvironment{theglossary}%
    {\begin{longtable}{llc}}%
    {\end{longtable}}%
 \renewcommand*{\glossaryheader}{%
  \bfseries Symbol&\bfseries Name and Units&
  \bfseries First used on Page No.\tabularnewline\endhead}%
  \renewcommand{\glossentry}[2]{%
    \glsentryitem{##1}\glstarget{##1}{\glossentryname{##1}} &
    \glossentrydesc{##1} \glsentryuseri{##1} & ##2\tabularnewline
  }%
}

\setglossarystyle{myunitstyle}

\begin{document}

\printglossaries

\newpage
This is the first use of \gls{L}.
\newpage
This is the second use of \gls{L}.

\end{document}
