MakeIndex, Nomenclature, Glossaries and Acronyms ⇒ glossaries / retrieve occurences between delimiters

[arobase]

Let's say I'm writing a play involving characters X, Y and Z. I'd like, at the beginning of each scene, to list the characters that included. Is that possible?

Example:

Code: Select all

\newglossaryentry{x}{name={X}, description={Role:  Played by: }}
\newglossaryentry{y}{name={Y}, description={Role:  Played by: }}
\newglossaryentry{z}{name={Z}, description={Role:  Played by: }}

%First scene

Cast %desired : x, y

Dialogue between \gls{x} and \gls{y}.

%Second scene

Cast %desired : z

Monologue by \gls{z}.

[nlct]

This assumes you're using makeindex. The code will have to be modified for xindy. (You'll need to change \scene to whatever's appropriate for your document.)

Code: Select all

\newglossaryentry{z}{name={Z}, description={Role:  Played by: }}

Hello,

I tried your solution in my document where I'm using an acronym-type glossary and a list of symbols that I defined myself using

\newglossary[slg]{symbols}{sym}{sbl}{List of Symbols}

I don't have any "main" glossary. In my case your code displays the acronyms used inside the cast but I would like to display the symbols from List of symbols used inside the cast instead. How is it possible? Also, I would like that the printed list be an unnumbered section named 'List of Symbols'.

Thank you,

Thomas

Can you provide a minimal example showing what you've tried and how the output differs from what you want. (I'm sorry it's not clear to me exactly what you require.)

\end{document}

The code above displays the acronyms used inside chapter 1 and 2. However, I would like it to display the symbols used inside chapter 1 and 2, each time with the command \symbolsChap.

I noticed that the use of the command \printglossary influences what is printed by \symbolsChap. For instance, if I use \printglossary[type=symbols] as well before the chapters, the symbols will be printed as well by \symbolsChap.

--> My problem: How to print only the symbols inside the chapters with \symbolsChap independently of the use of the command \printglossary?

Also, if possible, I would like the List of symbols printed in each chapter to be an unnumered section with the title 'List of symbols' instead of a list without title.

Thanks for your help!

Yes that's what i wanted, thanks a lot!

I still have a last issue, I cannot figure out how to align properly the columns of the lists printed with \symbolsChap. I tried something (see my previous code) but it doesn't go to the line when the text is too long. Also, it would be nicer to be able to center the last column (\glssymbol{}). The tab character & would do the work in a proper environment but here it doesn't.

Thanks for the help and for the great package!

Perhaps use \makebox and \parbox:

Code: Select all

    \newcommand{\itab}[1]{\makebox[.2\textwidth][l]{#1}}
    \newcommand{\taba}[1]{\parbox[t]{.6\textwidth}{#1}}
    \newcommand{\tabb}[1]{\makebox[.05\textwidth][c]{#1}}

        \bgroup
         \activatecast
         \renewcommand{\do}[1]{\noindent

Hello,

If I use the same code as above to retrieve the symbols used inside a chapter, the symbols that are used in exactly 2 chapters don't appear in the list anymore. If they are used in more than 2 chapters, then they appear in all the lists of symbols.

Here is a MWE where "Pdc" is used in both chapters and thus disappears for the symbol lists.

Would you know how to solve this problem?

Thank a lot

Thomas Geury

[nlct]

I think the implicit range formation applied by makeindex is causing the problem. You can disable it using the -r option, but only for the symbol list since the acronym list displays the page numbers:

Code: Select all

makeindex -s "test.ist" -t "test.alg" -o "test.acr" "test.acn"
makeindex  -r -s "test.ist" -t "test.slg" -o "test.sym" "test.sbl"

(where test.tex is the filename.)

The MWE was missing the siunitx package, and it needs a slight modification to \scansymbollist to ensure it works with the latest version of glossaries. Here's the modified version:
