% Make the name field in the glossary use a font changing command

% The following doesn't have the category explicitly set, so it
% defaults to "general":

\newglossaryentry{loremipsum}{name={lorem ipsum},
 description={dummy text}}

% The following set the category to "unit":

\newglossaryentry{ohm}{name=ohm,symbol={\si{\ohm}},
category=unit,
description=unit of electrical resistance}

\newglossaryentry{angstrom}{name={\aa}ngstr\"om,
category=unit,
symbol={\si{\angstrom}},sort=angstrom,
description={non-SI unit of length}}

% The selected style doesn't display the symbol
% so add it to the post-name hook:
\newcommand*{\glsxtrpostnameunit}{ (\glsentrysymbol{\glscurrententrylabel})}

% Insert the symbol after commands like \gls but only on first use
% (and only for the "unit" category):

\newcommand*{\glsxtrpostlinkunit}{%
 \ifdefempty\glscustomtext{\glsxtrpostlinkAddSymbolOnFirstUse}{}}
% The above "post-link" hook occurs after the link-text produced by 
% \gls so it's place outside the \unitfont argument.

% Mathematic constants need the "sort" key set because the "name"
% field contains commands:
\newglossaryentry{pi}{name={\ensuremath{\pi}},
sort=pi,
category=constant,
user1=pi,
description={ratio of a circle's circumference to its diameter}}

% Insert the description and "user1" text after commands like \gls but only on first use
% (and only for the "constant" category):

\newcommand*{\glsxtrpostlinkconstant}{%
 \ifdefempty\glscustomtext
 {\glsxtrifwasfirstuse{ (\glsentryuseri{\glslabel},
  \glsentrydesc{\glslabel})}{}}%
 {}}

% Insert the "user1" text after the description in the glossary
% but only for the "constant" category:
\newcommand*{\glsxtrpostdescconstant}{\space
 (\glsentryuseri{\glscurrententrylabel})}

% \newacronym sets the category to "acronym" by default. The
% "short-em" style makes it a regular entry.
\setabbreviationstyle[acronym]{short-em}

\newacronym{laser}{laser}{light amplification by
stimulated emission of radiation}

\newacronym{scuba}{scuba}{self-contained underwater breathing
apparatus}

% \newabbreviation sets the category to "abbreviation" by default.
% The "long-short-sc" style sets the regular attribute to false.
\setabbreviationstyle{long-short-sc}

\newabbreviation{html}{html}{hypertext markup language}

\newabbreviation{svg}{svg}{scalable vector graphics}

% The optional argument can be used to set a different category:
\setabbreviationstyle[bacteria]{long-em-short-em}
%\setabbreviationstyle[bacteria]{short-em}

% An alternative approach that uses \bacteriafont in the document
% and in the glossary is to provide a custom style:
%\newabbreviationstyle{bacteria}%
%{%
%  \GlsXtrUseAbbrStyleSetup{long-short}%
%}%
%{%
%  \GlsXtrUseAbbrStyleFmts{long-short}%
%  \renewcommand*{\glsabbrvfont}[1]{\bacteriafont{##1}}%
%  \renewcommand*{\glsfirstlongfont}[1]{\bacteriafont{##1}}%
%  \renewcommand*{\glslongfont}[1]{\bacteriafont{##1}}%
%}
% (the definition of \bacteriafont would need to be adjusted to
% include \emph)
%\setabbreviationstyle[bacteria]{bacteria}

\newabbreviation[category=bacteria]%
 {cbot}% label
 {C.~botulinum}% short
 {Clostridium botulinum}% long

\newabbreviation[category=bacteria]%
 {putida}% label
 {P.~putida}% short
 {Pseudomonas putida}% long

% Abbreviations that have translations. These put the translated
% text in the "user1" field. The "-user" abbreviation styles
% insert this field (if present) into the parenthetical material
% when used with \gls.

\setabbreviationstyle[foreign]{short-long-user}

% The fonts used by this style can be adjusted:
\renewcommand*{\glsabbrvuserfont}[1]{\textsf{\color{red}#1}}% short-form font
\renewcommand*{\glslonguserfont}[1]{\textsf{#1}}% long-form font

\newabbreviation[category=foreign,user1={French \TeX\ user group}]
 {gutenberg}{GUTenburg}{Groupe francophone des utilisateurs de \TeX}

% Insert the translation (user1) text after the description 
% in the glossary but only for the "foreign" category:
\newcommand*{\glsxtrpostdescforeign}{\space
 (Translation: \glsentryuseri{\glscurrententrylabel})}

% Now we have an awkward one that ends with a period:
\setabbreviationstyle[foreignenddot]{short-long-user}

% Need to discard the end of sentence period for the
% entries in this category.

\glssetcategoryattribute{foreignenddot}{discardperiod}{true}

% But not on first use (the user1 text doesn't end with a
% period):
\glssetcategoryattribute{foreignenddot}{retainfirstuseperiod}{true}

\newabbreviation
 [user1={German Speaking \TeX\ User Group},category=foreignenddot]
 {dante}{DANTE e.V.}{Deutschsprachige Anwendervereinigung \TeX\ e.V.}

% Insert the translation (user1) text after the description 
% in the glossary but only for the "foreignenddot" category:

% Insert page/pages tag before location list:

\chapter{Samples in the Main Document Text}

\section{All Entries}

First use (\verb|\gls|): \forglsentries{\thislabel}{\gls{\thislabel}. }

Next use (\verb|\gls|): \forglsentries{\thislabel}{\gls{\thislabel}. }

Using \verb|\glsfirst|: \forglsentries{\thislabel}{\glsfirst{\thislabel}. }

Using \verb|\glstext|: \forglsentries{\thislabel}{\glstext{\thislabel}. }

\section{Abbreviations only}
Abbreviations that have the \verb|regular| attribute set are
hybrids and can have odd results. In this example, the hybrid
entries are: 
\forglsentries{\thislabel}{%
 \ifglshasshort{\thislabel}%
 {% is an abbreviation
   \glsifregular{\thislabel}%
   {% is regular
     \texttt{\thislabel}.
   }%
   {}%
 }
 {}%
}

Using \verb|\glsxtrfull|: 
\forglsentries{\thislabel}{%
 \ifglshasshort{\thislabel}{\glsxtrfull{\thislabel}.  }{}}

Using \verb|\glsxtrshort|: 
\forglsentries{\thislabel}{%
 \ifglshasshort{\thislabel}{\glsxtrshort{\thislabel}.  }{}}

Using \verb|\glsxtrlong|: 
\forglsentries{\thislabel}{%
 \ifglshaslong{\thislabel}{\glsxtrlong{\thislabel}.  }{}}

\section{Symbols}

Using \verb|\glssymbol|:
\forglsentries{\thislabel}{%
 \ifglshassymbol{\thislabel}{\glssymbol{\thislabel}.  }{}}

\section{User Field}

Using \verb|\glsuseri|:
\forglsentries{\thislabel}{%
 \ifglshasfield{useri}{\thislabel}{\glsuseri{\thislabel}[.]  }{}}

(The full stop in the above is placed inside square brackets
to prevent the \verb|discardperiod| attribute from discarding it
since the \verb|useri| field doesn't end with a dot.)

\chapter{Math Mode}
Inline: $\gls{pi} = \frac{C}{d}$, display:

\[
 \gls{pi} = \frac{C}{d}
\]

\chapter{Samples in Headings}

Don't use commands like \verb|\gls| in section headings, but you can
use commands like \verb|\glsfmttext| or \verb|\glsfmtshort|.

\forglsentries{\thislabel}{%
 \ifglshasshort{\thislabel}%
 {\section{\glsfmtshort{\thislabel}}}%
 {%
% the constant entry "pi" can't be used in the PDF bookmarks,
% so use the user1 text for the bookmark
   \glsifcategory{\thislabel}{constant}
   {%
     \section{\texorpdfstring{\glsfmttext{\thislabel}}{\glsentryuseri{\thislabel}}}%
   }%
   {%
     \section{\glsfmttext{\thislabel}}%
   }%
 }%
 \Glsdesc[noindex]{\thislabel}.
