[sauvage]

According to the content of <symbol>, I would like to print it in italic followed by a comma, or not. I used the following redefinition (before \begin{document}), but it doesn't work, the symbol (eventually empty) and the comma are always printed. Where am I wrong? The acronym definition form is:

\newacronym[symbol={Symbol1}]{key1}{Acro1}{Definition1}

or

\newacronym{key2}{Acro2}{Definition2}

Code: Select all

   \renewcommand*{\glossaryentryfield}[5]{%
      \glsentryitem{##1}%                    %% Counter increment
      \glstarget{##1}{##2} &%                %% The acronym
      \ifx\@glo@symbol\@empty%               %% If present, the symbol
         \relax
      \else
         \textit{##4}, %
      \fi
      ##3 \\%                                %% The definition
   }

The symbol defaults to \relax rather than \@empty, so you need to test for \relax:

Code: Select all

   \renewcommand*{\glossaryentryfield}[5]{%
      \glsentryitem{##1}%                    %% Counter increment
      \glstarget{##1}{##2} &%                %% The acronym
      \ifx\relax##4%               %% If present, the symbol
         \relax
      \else
         \textit{##4}, %
      \fi
      ##3 \\%                                %% The definition
   }%
