bibleref/indextools: undefined control sequence: \indexspace ->idx:item

[hanetzer]

Got another one for ya.
Per the documentation on bibleref, Sec 3.3,
I've put together this mwe. Compiles fine with lualatex.

% vim: spell spelllang=en ft=tex
\documentclass[14pt,a4paper,english]{memoir}

\usepackage{bibleref}
\usepackage{indextools}

\makeindex[title=List of Scriptures,name=\jobname.scr]
\renewcommand{\biblerefindex}{\index[\jobname.scr]}
\begin{document}

\tableofcontents

\mainmatter

\chapter{Gen}
\ibibleverse{Gen}(1:1)
\ibibleverse{Exo}(1:1)
\printindex[\jobname]

\end{document}

Attempting to build with tex4ebook errors out on the index, with the error mentioned above,
but does eventually produce an epub file.
However, I must manually hit 'q' to continue the build at this point three times.

Thanks for the report. The main issue here is that indextools are not supported by TeX4ht. There are several issues:

• the \index command must write some additional info to the .idx file
• the theindex environenment must not be redefined
• the automatic index generation needs to be suppressed

It should be fixed using this file, indextools.4ht:

\def\:tempa[#1]#2{\html:addr%
\hbox{\Link-{}{dx\last:haddr
}\EndLink}%
%\@wrindex\:indexfile
\expandafter\protected@write\csname#1@idxfile\endcsname{}%\:indexfile{}%
{\string\beforeentry{\RefFileNumber\FileNumber}{dx\last:haddr
}{\a:makeindex}}%
\o:@index:[#1]{#2}%
}
\HLet\@index\:tempa%

\ifx \a:makeindex\:UnDef
\NewConfigure{makeindex}{1}\Configure{makeindex}{}
\fi
\Configure{@begin}{theindex}{\ind:defs}

% disable redefiniton of \theindex in \AtBeginDocument
\indtl@originaltrue

% prevent automatic compilation of the index
\let\KV@indtl@noautomaticfalse\KV@indtl@noautomatictrue
\KV@indtl@noautomatictrue
\indtl@disableautomatictrue


\Hinput{indextools}
\endinput

With this file, you shouldn't get errors. Then, you need to compile the index yourself, using this build file, build.lua:

if mode == "draft" then
  Make:htlatex{}
else
  Make:htlatex{}
  Make:xindex {idxfile="sample.scr.idx"}
  -- Make:xindex {}
  Make:htlatex{}
end

Unfortunately, I've found an error in the indexing script, so you will need also this file from make4ht.

With these changes, it should be possible to run:

$ tex4ebook -e build.lua -lf epub3 sample.tex

sorry for the delay in response, but the above works. regarding the make4ht file replacement, will that make its way upstream or is it a specific fix for my particular situation?

[michal-h21]

The indextools.4ht file is already included in TeX Live, so you shouldn't need it. You need just the build file.
