E:\texlive\2021\bin\win32\runscript.tlu:915: command failed with exit code 1:. How to solve this error?

I have using Windows and TeXLive2021.

elife is available here: https://github.com/zhoupc/eLife_submission/blob/master/elife.cls

Answer 1

The main problem is that the elife class loads Unicode-math package, which is not supported by TeX4ht. It even causes fatal error. To fix that, we need to create a special file that will prevent Unicode-math from loading, and define dummy version of \setmathfont.

Here is the file, unicode-math-hooks.4ht:

\:dontusepackage{unicode-math}
\RequirePackage{fontspec}
\NewDocumentCommand \setmathfont { O{} m O{} }{}

\endinput

We need to register this file in TeX4ht, using usepackage.4ht:

With this fix, you will not get a fatal error, but you will still get a compilation error caused by elife's additions to \maketitle. We can fix this issue with elife.4ht file:

\def\:tempa{%
     \a:themetadata%
     \textbf{*For correspondence:}  \@correspondence\par
     \ifx\empty\@contribution\else
     \c:themetadata\bigskip\@contribution\d:themetadata\fi
     \ifx\empty\@presentaddress\else
     \e:themetadata\textbf{Present address: }\@presentaddress\f:themetadata\fi
     \bigskip
     \ifx\empty\@deceased\else\g:themetadata\@deceased\h:themetadata\fi
     \b:themetadata%
}

\HLet\themetadata\:tempa

% redefine \@author to include affiliations and other information
\def\:tempa{\a:authlist\ifx\AB@affillist\AB@empty\AB@author\else
      \ifnum\value{affil}>\value{Maxaffil}\def\rlap##1{##1}%
    \c:authlist\AB@authlist\d:authlist\themetadata\e:authlist\AB@affillist\f:authlist
    \else  \AB@authors\fi\fi\b:authlist}
\HLet\@author\:tempa

\NewConfigure{themetadata}{8}

\NewConfigure{authlist}{6}

\renewenvironment{abstract}{%
   \textcolor{eLifeLightBlue}{\large\bfseries\abstractname\space}
}{%   
}

\Hinput{elife}
\endinput

It inserts some configurable hooks that can be used to insert HTML code. Yu can configure these hooks in a .cfg file:

\Preamble{xhtml}

% configure environments in \maketitle
\Configure{authlist}
{\ifvmode\IgnorePar\fi\EndP\HCode{<div class="authlist">}}
{\ifvmode\IgnorePar\fi\EndP\HCode{</div>}}
{\HCode{<div>}}{\HCode{</div><div>}}{\HCode{</div><div>}}{\HCode{</div>}}

\Configure{themetadata}
{\ifvmode\IgnorePar\fi\EndP\HCode{<div class="themetadata">}}
{\ifvmode\IgnorePar\fi\EndP\HCode{</div>}}
{\HCode{<div>}}{\HCode{</div><div>}}{\HCode{</div><div>}}
{\HCode{</div><div>}}{\HCode{</div><div>}}{\HCode{</div>}}
\Css{.themetadata{font-size:0.8rem;}}

\def\IgnoreRule{\special{t4ht@\string_}}
\def\EndIgnoreRule{\special{t4ht@\string_\string_}}

\ConfigureEnv{abstract}
{\ifvmode\IgnorePar\fi\EndP\HCode{<section role="doc-abstract" class="abstract">\Hnewline}\IgnoreRule}
{\ifvmode\IgnorePar\fi\EndP\HCode{</section>\Hnewline}\EndIgnoreRule}{}{}

\Css{.authlist span{font-size:0.8rem;}}
\begin{document}
\EndPreamble

It should compile correctly now:
