Different style for acronyms

Question

In 1 I had the answer on how to put the translation of an acronym and used both English and Spanish version.

The issue now is that I have acronyms that are only Spanish, others only English without translation and English with translation. The format for the document mandates that English is written emphasized while Spanish is in normal.

Is there any way of automating it? I was thinking on having 2 list, English acronyms and only Spanish, then load them, assigning a different style and then merging them so in the list of acronyms they appear in order.

The other solution I have found is on my acronym's list create two styles:

\newcommand{\engstyle}[1]{\emph{#1}}
\newcommand{\espstyle}[1]{#1}
\newacronym{ENG}{ENG}{\engstyle{English acronym}} %
\newacronym{ESP}{ESP}{\espstyle{Spanish acronym}} %

But then in the list of acronyms they appear with the assigned style. And I want them without any style.

Any suggestion?

Edit: What I want as exit.

Within the test English acronym (ENG) is displayed and the Spanish one this way, Spanish acronym (ESP).

List of Acronyms

ENG English acronym

ESP Spanish acronym

Edit 2: I didn't realize that Nicola updated the package. Now the question is: Is it possible to set multiple setacronymstyle within the same doc?

Answer 1

It's not possible to use multiple acronym styles (one will usually override another). However, here's a possible solution that uses the user1 key to store the font style to use when you define an acronym:

% arara: pdflatex
% arara: makeglossaries
% arara: pdflatex
% arara: pdflatex

\documentclass{article}

\usepackage[acronym]{glossaries}

\makeglossaries

\newcommand*{\engstyle}[1]{\emph{#1}}
\newcommand*{\espstyle}[1]{#1}

\newcommand*{\newengacronym}[4][]{%
  \newacronym[user1=\protect\engstyle,#1]{#2}{#3}{#4}%
}

\newcommand*{\newespacronym}[4][]{%
  \newacronym[user1=\protect\espstyle,#1]{#2}{#3}{#4}%
}

\newacronymstyle{lang}
{%
  \GlsUseAcrEntryDispStyle{long-short}%
}%
{%
  \GlsUseAcrStyleDefs{long-short}%
  \renewcommand*{\genacrfullformat}[2]{%
   \glsentryuseri{##1}{\glsentrylong{##1}}##2\space
   (\glsentryshort{##1})%
  }%
  \renewcommand*{\Genacrfullformat}[2]{%
   \glsentryuseri{##1}{\Glsentrylong{##1}}##2\space
   (\glsentryshort{##1})%
  }%
  \renewcommand*{\genplacrfullformat}[2]{%
   \glsentryuseri{##1}{\glsentrylongpl{##1}}##2\space
   (\glsentryshortpl{##1})%
  }%
  \renewcommand*{\Genplacrfullformat}[2]{%
   \glsentryuseri{##1}{\Glsentrylongpl{##1}}##2\space
   (\glsentryshortpl{##1})%
  }%
}

\setacronymstyle{lang}

\newengacronym{ENG}{ENG}{English Acronym}
\newespacronym{ESP}{ESP}{Spanish Acronym}

\begin{document}

First use : \gls{ENG}, \gls{ESP}.

Next user: \gls{ENG}, \gls{ESP}.

\printglossaries

\end{document}

This produces:

Edit:

If you want to redefine \glsentrylong, you'll also need to redefine \Glsentrylong otherwise you'll cause a problem for \makefirstuc:

% arara: pdflatex
% arara: makeglossaries
% arara: pdflatex
% arara: pdflatex

\documentclass{article}

\usepackage[acronym]{glossaries}

\makeglossaries

\newcommand*{\engstyle}[1]{\emph{#1}}
\newcommand*{\espstyle}[1]{#1}

\newcommand*{\newengacronym}[4][]{%
  \newacronym[user1=\protect\engstyle,#1]{#2}{#3}{#4}%
}

\newcommand*{\newespacronym}[4][]{%
  \newacronym[user1=\protect\espstyle,#1]{#2}{#3}{#4}%
}

\makeatletter
\newacronymstyle{lang}
{%
  \GlsUseAcrEntryDispStyle{long-short}%
}%
{%
  \GlsUseAcrStyleDefs{long-short}%
  \renewcommand*{\glsentrylong}[1]{%
    \glsentryuseri{##1}{\@gls@entry@field{##1}{long}}}%
  \renewcommand*{\glsentrylongpl}[1]{%
    \glsentryuseri{##1}{\@gls@entry@field{##1}{longpl}}}%
  \renewcommand*{\Glsentrylong}[1]{%
    \glsentryuseri{##1}{\@Gls@entry@field{##1}{long}}}%
  \renewcommand*{\Glsentrylongpl}[1]{%
    \glsentryuseri{##1}{\@Gls@entry@field{##1}{longpl}}}%
}
\makeatother

\setacronymstyle{lang}

\newengacronym{ENG}{ENG}{English Acronym}
\newespacronym{ESP}{ESP}{Spanish Acronym}

\begin{document}

First use : \gls{ENG}, \gls{ESP}.

Next user: \gls{ENG}, \gls{ESP}.

Long form: \acrlong{ENG}, \acrlong{ESP}.

Long form (first UC): \Acrlong{ENG}, \Acrlong{ESP}.

Plural long form: \acrlongpl{ENG}, \acrlongpl{ESP}.

Plural long form (first UC): \Acrlongpl{ENG}, \Acrlongpl{ESP}.

\printglossaries

\end{document}

However if you do the above, you'll no longer be able to use \glsentrylong in PDF bookmarks.
