adding '\usepackage{cleveref}' erroneously changes minted output

[alder711]

Hi, Michal.

I am encountering a peculiar issue. Let's say I have the following in main.tex:

\documentclass{article}
        \usepackage{minted}
        \usepackage{xcolor}

        \definecolor{light-gray}{gray}{0.85}
        \setminted{
                numbers=none,
                showspaces=false,
                breaklines=true,
                fontfamily=tt,
                frame=single,
                obeytabs=false,
                stripall=true,
                tabsize=8,
                bgcolor=light-gray
        }

\begin{document}
        \begin{minted}{bash}
int main() {
        int val = 0;
        val++;
        return val;
}
        \end{minted}
\end{document}

and I compile with make4ht --format html5+latexmk_build --backend tex4ht --loglevel info --shell-escape main.tex, I get the following rendition:

All looks well to me here. However, if I add a \usepackage{cleveref} like so in main.tex:

\documentclass{article}
        \usepackage{minted}
        \usepackage{xcolor}
        % Added Here
        \usepackage{cleveref}

        \definecolor{light-gray}{gray}{0.85}
        \setminted{
                numbers=none,
                showspaces=false,
                breaklines=true,
                fontfamily=tt,
                frame=single,
                obeytabs=false,
                stripall=true,
                tabsize=8,
                bgcolor=light-gray
        }

\begin{document}
        \begin{minted}{bash}
int main() {
        int val = 0;
        val++;
        return val;
}
        \end{minted}
\end{document}

I get some extra space on the first line like so: and I see the extra space in the HTML (note the two spaces in between the <pre> and <a> tags):

...
   <div class='minted-color-box' style='background-color:#D9D9D9'>
   <pre class='fancyvrb' id='fancyvrb1'>  <a id='x1-8r1'></a>
...

Software versions:

• make4ht: v0.3l
• texlive: TeX Live 2022/Arch Linux

Am I missing something here? Any help would be greatly appreciated. Thanks in advance!

Thanks for the report. It is caused by non-commented end lines in some definitions in cleveref.4ht. This version should fix that:

Awesome, that change worked. Thanks for your active development, @michal-h21 !
