I found a lot of information on this forum about how to present the entries into a glossary (uppercase, lowercase, first letter capitalized); but I don't understand how to have two different styles for the acronyms list and the glossary, and present the entries differently. Here is the code I use to capitalize the first letter into the glossary; but this affects the acronym list and the glossary. It's OK for the glossary, but I want the acronym entries in uppercase for the whole words...

Here is a full MWE...




%% Capitalize the first letter of the entry %%%%%%%%%



  \seq_clear:N \l_capitalize_words_seq
  \seq_use:Nn \l_capitalize_words_seq { ~ }
  \capitalize_word:n { #1 }

  \cs_set_eq:Nc \capitalize_tl_set:Nn { protected@edef }
  \cs_set_eq:NN \capitalize_tl_set:Nn \tl_set:Nn

\cs_new_protected:Nn \capitalize_word:n
  \capitalize_tl_set:Nn \l_capitalize_word_tl { #1 }
  \seq_if_in:NfTF \g_capitalize_exceptions_seq { \tl_to_str:n { #1 } }
   % exception word
   { \seq_put_right:Nn \l_capitalize_words_seq { #1 } } % exception word
   % to be uppercased
   { \seq_put_right:Nx \l_capitalize_words_seq { \tl_mixed_case:V \l_capitalize_word_tl } }
\cs_generate_variant:Nn \tl_mixed_case:n { V }
  \clist_map_inline:nn { #1 }
    \seq_gput_right:Nx \g_capitalize_exceptions_seq { \tl_to_str:n { ##1 } }
\cs_generate_variant:Nn \seq_if_in:NnTF { Nf }
\seq_new:N \l_capitalize_words_seq
\seq_new:N \g_capitalize_exceptions_seq

\newacronym{gcd}{GCD}{Greatest Common Divisor}

\newacronym{lcm}{LCM}{Least Common Multiple}


The \Gls{latex} typesetting markup language is specially suitable 
for documents that include \gls{maths}. \Glspl{formula} are 
rendered properly an easily once one gets used to the commands.

Given a set of numbers, there are elementary methods to compute 
its \acrlong{gcd}, which is abbreviated \acrshort{gcd}. This 
process is similar to that used for the \acrfull{lcm}.



  • Please provide a full MWE. From what you have written in question, I guess you are looking for commands \setglossarystyle, \setacronymstyle and such. If so, they are described in package docs. And thumbs up for using ExplSyntax ;) Commented Sep 21, 2020 at 14:43
  • Thanks ; I edited my previous message providing a full MWE. \setacronymstyle{short-sc-long} doesn't work for me with \usepackage[style=tree]{glossaries-extra} ? Commented Sep 24, 2020 at 20:28
  • Well, the part with Expl3 definition is too complex for me, but you might look at this question: tex.stackexchange.com/questions/562957/… where some else had similar requirement, but he just created new abbreviation (acronym) style. I think you could reuse most of the code there, and have different style for your main glossary. All the same you could translate that to Expl3 if you like. Commented Sep 25, 2020 at 7:09

Finally, the solution is when you call the acronyms: you have to modify you glsnamefond command like this: \renewcommand{\glsnamefont}[1]{#1} \printglossary[type=\acronymtype] It works now: acronyms are in uppercase, only the first letter is capitalized in the glossary.
