\nameref of hyperlink package

[danielezambelli]

Hi!

Is it possible to implement "\nameref" of the "hyperlink" package?

Mini-example:

%--8<-------------------------------------
`
\documentclass[10pt,a4paper]{memoir}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{lipsum}

\ifdefined\HCode % compilazione htlatex
\def\pgfsysdriver{pgfsys-dvisvgm4ht.def}
\newcommand{\url}[1]{\Link[#1]{}{} #1 \EndLink}
\newcommand{\href}[2]{\Link[#1]{}{} #2 \EndLink}
\newcommand{\hypertarget}[2]{\Link[]{}{#1} #2 \EndLink}
\else % compilazione pdflatex
\RequirePackage[colorlinks=true]{hyperref}
\fi

\newcommand{\numnameref}[1]{\ref{#1} \nameref{#1}}

\begin{document}

\chapter{Primo capitolo}

\section{Sezione a}
\label{sec:pri_a}

\lipsum[1-2]

\section{Sezione b}
\label{sec:pri_b}

\lipsum[3-6]

\section{Sezione c}
\label{sec:pri_c}

\lipsum[7-9]

\section{Esercizi}

\subsection{Esercizi dei singoli paragrafi}

\subsubsection*{\numnameref{sec:pri_a}}

\subsubsection*{\numnameref{sec:pri_b}}

\subsection{Esercizi di riepilogo}

\end{document}

Thank you very much!

It works, but it seems that inside sectioning commands, referencing commands don't produce links. But it still produces correct text. But when you use it in normal text, it produces even link. Try this:

\documentclass[10pt,a4paper]{memoir}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{lipsum}

% \ifdefined\HCode % compilazione htlatex
% \def\pgfsysdriver{pgfsys-dvisvgm4ht.def}
% \newcommand{\url}[1]{\Link[#1]{}{} #1 \EndLink}
% \newcommand{\href}[2]{\Link[#1]{}{} #2 \EndLink}
% \newcommand{\hypertarget}[2]{\Link[]{}{#1} #2 \EndLink}
% \else % compilazione pdflatex
\RequirePackage[colorlinks=true]{hyperref}
% \fi

\newcommand{\numnameref}[1]{\ref{#1} \nameref{#1}}

\begin{document}

\chapter{Primo capitolo}

\section{Sezione a}
\label{sec:pri_a}

\lipsum[1-2]

\section{Sezione b}
\label{sec:pri_b}

\lipsum[3-6]

\section{Sezione c}
\label{sec:pri_c}

\lipsum[7-9]

\section{Esercizi}

\subsection{Esercizi dei singoli paragrafi}

\subsubsection*{\numnameref{sec:pri_a}}

\subsubsection*{\numnameref{sec:pri_b}}

In text: \numnameref{sec:pri_b}

\subsection{Esercizi di riepilogo \url{https://google.com/}}

\end{document}

See the difference between \subsubsection*{\numnameref{sec:pri_b}} and In text: \numnameref{sec:pri_b}.

It works, but when I compile with:
make4ht numnameref.tex -c md_make4ht -l -u -s -d dist "mathjax"

I get the following error
[ERROR] htlatex: Compilation errors in the htlatex run
[ERROR] htlatex: Filename Line Message
[ERROR] htlatex: ./md_make4ht. 4 LaTeX Error: Missing \begin{document} in `md_make4ht.cfg'.:

My config file is:
md_make4ht.txt

Where is the error?

Thanks.

[michal-h21]

You can try to run make4ht with the -a debug option to get context of the error. In this case, your configuration file contains configurations for the ulem package, but your document don't use it, so all \Configure commands got interpreted. So adding \usepackage{ulem} to your document should fix it. But you also need updated TeX Live, as it needs the correct version of ulem.4ht.

[danielezambelli]

The command:

make4ht numnameref.tex -l -u -s "mathjax"

make4ht does not compile your text correctly.

It does not display \nameref correctly.

Why?

Thank you for your attention.

[michal-h21]

Thanks for the report. This seems to be caused by Memoir, it redefines \nameref somehow. I will need to investigate it and try to find a fix for that.

[michal-h21]

This file, memhfixc.4ht should fix this issue:

\Hinput{memhfixc}
\endinput

[danielezambelli]

If the file memhfixc.4ht is in the same directory as the file to be compiled , it works, but if I copy it to the dir

/usr/share/texlive/texmf-dist/tex/generic/tex4ht/

it has no effect.

ll /usr/share/texlive/texmf-dist/tex/generic/tex4ht/mem*.*
Permissions Size User Group Date Modified Name
.rw-r--r-- 934 root 19 Mar 18:55 /usr/share/texlive/texmf-dist/tex/generic/tex4ht/memhfixc.4ht

What am I doing wrong?

Thank you.

[michal-h21]

Does the kpsewhich memhfixc.4ht command find the file? Maybe you need to run the texhash command, it should update the file database, and it may work then.

[danielezambelli]

No, he can't find it.
Isn't it sufficient to copy the file to the directory?

[michal-h21]

I think it isn't, as TeX uses database of files for faster access. At least it used to do, I am not sure if it still does that. You can also can try to put the file in ~/texmt/tex/generic/tex4ht (and validate if it is accessible with kpsewhich).

[danielezambelli]

Unfortunately, our project is quite complex also uses tcolorbox, and this complicates things.

I modified the minimal example to make it more like the document in production.

The references are stoned.

Thank you for your attention and competence.

This example seems to work with TeX4ht sources, but TeX Live 2023 wasn't updated yet.
