Subject: [tex4ht] Question on using .cfg and \DeclareGraphicsExtensions
Message-ID: <c46845a3-caec-cc5e-e2fa-923e63ab17f1@12000.org>

Hello;

In my tex4ht .cfg file, which I use for all the builds, it
has the following

--------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\DeclareGraphicsExtensions{.svg,.png}
\Configure{Picture}{.svg}
etc....
---------------------

The use of \DeclareGraphicsExtensions{.svg,.png} is needed
to allow the code below it to work.

The above works well, as long as I make sure to
add

\usepackage{graphicx}

in each Latex file which is being compiled by make4ht,
otherwise will get an error

! Undefined control sequence.
l.4 \DeclareGraphicsExtensions

So in all my latex files, I include the graphics package
even though it might not be used, just to avoid this error.

Is there a way around this? I can't include the graphics
package itself in the .cfg, and I need to use the
command \DeclareGraphicsExtensions in .cfg file.

If you like to see the full .cfg I am using
and the full commands, they are listed here

https://www.12000.org/my_notes/faq/LATEX/htch4.htm#x5-680004.1

Thanks

you can use \@ifpackageloaded{graphicx} for test of its presence. The
full configuration file is bellow:

-----------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}

\makeatletter
\@ifpackageloaded{graphicx}{%
\DeclareGraphicsExtensions{.svg,.png}

%this below to make it resize the SVG image, if it is there, to

            \space style="width:\CalcRem{\Gin at req@width}em;"
            }%
            \special{t4ht+ at File: \csname Gin at base\endcsname.svg}

The command \@ifpackageloaded{graphicx} worked great, I did
not know about it.

Subject: [tex4ht] new problem with tex4ht and matjax,
 table of content with math in section titles
Message-ID: <715727b5-8ab1-3f4a-d1a8-beeea67bff6f@12000.org>

Hello;

I am not sure if this is a mathjax issue or tex4ht. It
only shows up when using mathjax with tex4ht.

Here is the MWE first

--------------------------------
\documentclass[11pt]{article}%
\begin{document}
\tableofcontents
\section{$u(0)=0,u^{\prime}(L)=0$}
test1

\section{$u(0)=0, u\left(L \right) +u^{\prime}(L)=0$}
test 2
\end{document}
-------------------------------

The problem is in the table of content that shows up. It looks
like this

https://www.12000.org/tmp/101018/toc.jpg

The command used to compile it is

make4ht -ulm draft  -c ./nma_mathjax.cfg foo.tex
     "htm,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

Where nma_mathjax.cfg is (using the minimal version)

----------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
-------------------

The file mathjax-latex-4ht.sty was downloaded from

https://raw.githubusercontent.com/michal-h21/helpers4ht/master/mathjax-latex-4ht.sty

It seems related to mathjax, since when I compile
the same file using my old .cfg file, which does
not use mathjax but uses svg, the TOC looks fine and
math in the section title is not corrupted.

Also the PDF is ok when compiling using lualatex foo.tex.

Any hints or ideas when the TOC is messed up when using
mathjax? Is one not supposed to use math in section titles
with mathjax?

Using texlive 2018.

Thanks

It seems that \left and \right commands are expanded once when written
to TOC. I've fixed this issue in the MathJax support file, but it is
possible that such issues may happen again. TOC business is quite huge
in tex4ht and it is hard to debug.

Hello there,
I'm unable to install the "install-tl" file from the command line.
What I'm doing is:
# perl install-tl

it returns:
# cannot contact mirror.ctan.org, returning a backbone server!
Loading http://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb
install-tl: TLPDB::from_file could not download
http://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb;
install-tl: maybe the repository setting should be changed.


I already tried using "rsync" or wget to change the repository http
though the problems remain. I use proxy to navigate. As said in the
subject, I run CentOS7 and the installation from their repo gives lot
of package errors after installing. Therefore I downloaded the
install-tl file to install by myself.

Thanks for any help.

Thanks again Michal.

I downloaded your style file from

https://github.com/michal-h21/helpers4ht

And it worked very well. TOC looks OK now with mathjax.

I hope in texlive 2019 these style files will become part of
texlive.

I will add it eventually, even in TL 2018. I have just too long ToDo list :(

You are asking on the wrong mailing list.  Ask here:

  http://tug.org/mailman/listinfo/tex-live

BTW, it's quite unusual that mirror.ctan.org is inaccessible.  You can
use the -repository option in order to try another repository, see

  http://tug.org/texlive/doc/tlmgr.html#OPTIONS

  Reinhard

Subject: [tex4ht] Another problem compiling tex4ht to HTML using mathjax

Message-ID: <6a084cf5-a553-7516-7371-b20796c0c891@12000.org>

I've found another issue using mathjax mode with make4ht.

The following MWE compiles OK using lualatex and when using
svg and when using default png. But when using mathjax it gives
strange error:

------------------------------------
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html5.4ht)) (./foo.aux))
(/usr/local/texlive/2018/texmf-dist/tex/latex/lm/ot1lmtt.fd)
Runaway argument?
\int _{0}^{1}x\ J_{p}\left ( ax\right ) \ J_{p}\left ( bx\right ) \ d\ETC.
! Forbidden control sequence found while scanning use of \AltMathOne.
<inserted text>
\par
l.8 0 &
       if\ a\neq b\\
? x
-------------------------

This code comes from auto-generated Latex code. But as I said
above, it compiles OK, except when using mathjax. So it seems
some conflict with may be the style file used or something
mathjax does not like?

I am using the same command:

make4ht -ulm default  -c ./nma_mathjax.cfg
         foo.tex "htm,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

Where nma_mathjax.cfg is (using the minimal version)

----------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
-------------------

The file mathjax-latex-4ht.sty was downloaded from

https://github.com/michal-h21/helpers4ht/blob/master/mathjax-latex-4ht.sty

When I remove the mathjax, it compiles OK, i.e. using this command

make4ht -ulm default foo.tex
        "htm,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

No error.

Here is the latex file
-----------------
\documentclass[11pt]{article}%
\usepackage{amsmath}
\begin{document}
\begin{tabular}[c]{|l|p{5.5in}|}\hline
Orthogonality & $\int_{0}^{1}x\ J_{p}\left(  ax\right)  \ J_{p}\left(

\frac{1}{2}J_{p+1}^{2}\left(  a\right)  =\frac{1}{2}J_{p-1}^{2}\left(
a\right)  =\frac{1}{2}J_{p}^{^{\prime}2}\left(  a\right)   & if\ a=b
\end{array}
\right.  \ a,b$ are zeros of $J_{p}$\\\hline

\ \ $\frac{d}{dx}\left[  \frac{1}{x^{p}}J_{p}\right]  =-\frac{1}{x^{p}}%

-J_{p+1}=2J_{p}^{\prime}$\\\hline
\end{tabular}

\end{document}
----------------------------------

In case the above gets messed up in the email, I've also put a copy
here

https://www.12000.org/tmp/10142018/foo.tex

Thanks for any hints on what the problem is.  This mathjax seems
like a tricky thing integrate with tex4ht. I am only using it
becuase it makes compiling with tex4ht very fast.

the issue is with & characters in your inline math. It is not
MathJax's fault, it is issue with TeX parsing. I don't know how to fix
that, playing with catcodes didn't help. Only solution I've found is
to use { } around the problematic math element (not every one, just
the problematic ones). So your example may look like this:

\documentclass[11pt]{article}%
\usepackage{amsmath}
\begin{document}
\begin{tabular}[c]{|l|p{5.5in}|}\hline
Orthogonality &{$\int_{0}^{1}x\ J_{p}\left(  ax\right)  \ J_{p}\left(
bx\right)  \ dx=\left\{
\begin{array}[c]{ll}%
0 & if\ a\neq b\\
\frac{1}{2}J_{p+1}^{2}\left(  a\right)  =\frac{1}{2}J_{p-1}^{2}\left(
a\right)  =\frac{1}{2}J_{p}^{^{\prime}2}\left(  a\right)   & if\ a=b
\end{array}
\right.  \ a,b$} are zeros of $J_{p}$\\\hline
recursive formula & $\frac{d}{dx}\left[  x^{p}J_{p}\right]  =x^{p}J_{p-1}$,
\ \ $\frac{d}{dx}\left[  \frac{1}{x^{p}}J_{p}\right]  =-\frac{1}{x^{p}}%
J_{p+1},$ \ \ $J_{p-1}+J_{p+1}=\frac{2p}{x}J_{p},$ \ \ \ $J_{p-1}%
-J_{p+1}=2J_{p}^{\prime}$\\\hline
\end{tabular}

\end{document}

If anybody know a better solution, I would be happy :)

Thanks Michal for looking at this. I've just changed the code
as you showed in the file I have, (there were more cases
like the one in the example above). So I added {} around all of them
and now it compiles ok with mathjax.

But what I do not understand, is that you say it is a tex parsing
issue.  But why it only happen when using mathjax mode?

Thanks,

Fine :)

Because the math contents are being passed to a TeX macro that
converts it to a plain text that is written to the HTML code. This
normally doesn't happen in MathML or picture math output.

Best,

Posted at 

https://tex.stackexchange.com/questions/455994/tex4ht-fails-with-scrartcl-class-when-defining-rm-command-argument-of-popthre

This MWE compiles OK with lualatex and pdflatex but fails with tex4ht. Why?
And this happens only when using scrartcl and not with article.

---------------------
\documentclass[11pt]{scrartcl}%{article}
\DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}

\begin{document}
test
\end{document}
------------------

Now

------------------
 make4ht -ulm draft foo.tex
 ....
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html5.4ht))
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/scrartcl.4ht
! Argument of \popthree has an extra }.
<inserted text>
\par
l.33 \:temp{rm}
?
------------------------

I also tried

 \documentclass[11pt,enabledeprecatedfontcommands]{scrartcl}

But make4ht still gave same error.

Follow-up Comment #1, bug #403 (project tex4ht):

tex4ht patches the old font commands in the code for basic classes.
configuration for scrartcl class duplicates this code, otherwise the
compilation fails. 

I don't really understand this patching in the first place, I cannot see any
difference when it is removed, other than that Nasser's code can compile
without error. It seems like a really old hack that isn't useful any more.
I've removed the patching from the .4ht files, but kept them in the sources,
so it can be returned back if it causes any issues.

Follow-up Comment #1, bug #172 (project tex4ht):

I can't confirm the behaviour for \ref{} and \cite{} but only for \footnote{}
and \footcite{}.

In those cases, there is a possibility for a dirty workaround:

$ cat /usr/share/texmf/tex4ht/base/unix/tex4ht.env | sed -E
"s:(4oo.+)(mv):\1sed -E 's/( )\{2,\}(<t4htlink)/\\\\2/g':g"  >
~/texmf/tex4ht/base/unix/tex4ht.env && mktexlsr

This changes the "packing" behaviour of "-coo" to not just move the generated
content.xml, but to replace the unwanted whitespaces first. For my usecase
this seems to work. (Make sure the paths are correct and exist on your system
and that you don't override already existing custom settings on your system!)


This workaround is based on some assumptions:

1. The Bug seems to be fixed for \ref and \cite
2. But it is still present for footnotes
3. A single whitespace before a link tag is valid and there because the
TeX-Author wanted it
4. Multiple Spaces are Bug-induced code that is completely unwanted.

Follow-up Comment #2, bug #172 (project tex4ht):

Thank you for the report, the original issue indeed seems to be fixed. 

The footnote issue can be fixed without need to use sed. I cannot find the
source of the spurious spaces, but tex4ht can be instructed to ignore spaces
using the \special{t4ht@)} command. I've added this command to the footnote
configuration in the ooffice configuration file and it seems to fix the issue.


BTW, it is better to use 

   make4ht -f odt filename.tex

instead of the old mk4ht oolatex, it fixes lot of issues with file names,
Unicode and it also supports filtering of the XML files before the xt-pipes
processing. See https://tex.stackexchange.com/a/447968/2891 for example.

The additional information about tex4ht \special commands can be found for
example here: https://www.kodymirus.cz/src4ht/tex4ht-moz18.html

    _______________________________________________________

Details:

When using \label{} and \ref{} (or \pageref{} in TeX, the opendocument output
seems to be broken. The referenced Label is just not rendered visibly.

I've attached a MWE and the generated .odt file.

I'm using:

htxelatex test-labelref.tex "xhtml,ooffice" "ooffice/! -cmozhtf" "-coo
-cvalidate"

to generated that file.
When running xelatex to generate a pdf file, everything works fine.

The TeX-Code line
<pre>
Something about Section \ref{sec:1} and --\ref{sec:2}-- to show something else
on p.~\pageref{sec:1}.
</pre>

results in 
<pre>
<!--l. 22--><text:p text:style-name="Text-body">Something about Section
<t4htlink 
 href="#x1-10001">1<!--tex4ht:ref: sec:1 --></t4htlink> and &#x2013;<t4htlink

 href="#x1-20002">2<!--tex4ht:ref: sec:2 --></t4htlink>&#x2013; to show
something else on p.<text:s/><t4htlink 
 href="#x1-10001">3</t4htlink>.
    </text:p>
</pre>

So, in summary, the reference is rendered, but not in the correct way. (Btw,
shouldn't it be text:reference-ref instead of t4htlink? See
http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part1.html#element-text_reference-ref)

If you need any further information to reproduce the behaviour, please let me
know.

Message-ID: <d8b48824-9275-aef6-e92c-f06f87fda0b6@12000.org>

Hello;

This MWE only fails to compile when using make4ht in mathjax mode.

It is snippet from old code. May be not well written. But
this used to compile OK and still compiles OK when not using
mathjax mode in make4ht.

--------------------------------
\documentclass[11pt]{article}
\usepackage{amsmath,mathtools,amssymb}

\begin{document}
\begin{tabular}[c]{|l|l|}\hline
$
   \begin{tabular}[c]{l}%
     $i\in C(J)$\\
     $j\notin C(J)$
\end{tabular}
$ & $f_{ij}=0$\\\hline
\end{tabular}
\end{document}
------------------------------------

Now when I compile it with mathjax, it gives this error

-------------------------------------
(/usr/local/texlive/2018/texmf-dist/tex/latex/amsfonts/umsb.fd)
(/usr/local/texlive/2018/texmf-dist/tex/latex/lm/ot1lmtt.fd)
! Missing $ inserted.
<inserted text>
$
l.10     $j\notin
                 C(J)$
? x
----------------------------------

command used

make4ht -ulm default  -c  ./nma_mathjax.cfg foo.tex
        "htm,0,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

Where nma_mathjax.cfg is

--------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
-------------

And mathjax-latex-4ht.sty is

https://github.com/michal-h21/helpers4ht/blob/master/mathjax-latex-4ht.sty

Why does it fail only in mathjax mode? It compiles OK in lulatex,
and svg.

I think it is more serious than whether or not mathjax is used.

Why place "tabular" inside math, especially inline math?

This cannot sensibly become HTML because one cannot put a block element
-- <table> -- inside an inline element -- <math display="inline">.

Making use of a suitable LaTeX profile should trap problems of this
type.

(I find that simply removing the '$' markup in the first
cell of the outer tabular surrounding the inner tabular will
fix it.)

I use Scientific word. This is very old document for a HW. May be
10 years old. I must have selected the table in the GUI and then
pressed math mode button. This made SW put a $$ around the table.

The point is, this compiles with no problem. I've compiled this folder
many times before when I run make on the source tree, It only gives
now since I am using mathjax mode.

Agree, I would not select math mode now when making table like this
in SW. I will try to change it in SW.

Yes. Removing $$ from outside inner table removes the error.
But again, if this is an invalid latex, then lualatex should give
an error. But it compiles it with no error. Using TL 2018.

lualatex maybe isn't complaining, but it really doesn't make sense to
use tabular inside inline math. I don't think that it would work for
MathML either. Even if you managed to compile it and keep the table as
LaTeX code, MathJax doesn't support tabular, so it cannot render it.

Best,
Michal

Follow-up Comment #1, bug #404 (project tex4ht):

It seems that post-processing by Xtpipes haven't been executed on the
content.xml file, because it should replace <t4htlink> tags with valid
OpenDocument elements.

Anyway, on my machine Xtpipes replace only some links, they doesn't replace
the destinations in section titles. I also think text:a element should be used
for links to get the hyperlink functionality.

I've created Lua filter for make4ht that replaces the link handling in
xtpipes. The links produced by it are clickable.

The modified xtpipes file, make4ht build file and sample ODT file are
attached.

The command used for the compilation is

     make4ht -uf odt test-labelref.tex "TocLink"

It is necessary to use the development version of make4ht[1], because I fixed
some bugs while working on this example.

Subject: [tex4ht] big problem with table of content when section titles
 contain math using mathjax
Message-ID: <9bd20b8f-8b36-9006-9488-0438cbb5e20c@12000.org>

Hello, I found a really big problem using mathjax with tex4ht.

When a section or subsection title contain math, the table of content
that shows in HTML is all corrupted. This is only when using mathjax
mode.  Add \cprotect{} around the section of subsection title that
contains math had no effect.

These files were compiled fine as is for years with no problem before
when using svg for math.

I made a MWE to show the problem.
============
\documentclass[12pt]{article}
\usepackage{amsmath,mathtools,amssymb}
\usepackage{graphicx}

\begin{document}
\title{MWE showing the pronblem}
\maketitle

\tableofcontents

\section{Listing of integrals}
\subsection{\quad $\int e^x \left(1-x^3+x^4-x^5+x^6\right) \, dx$}
test
\subsection{\quad $\int \frac{e^{\frac{x}{2+x^2}} \left(2-x^2\right)}{2 x+x^3} \, dx$}
test2
\end{document}
===================

Here is a screen shot showing the result

https://www.12000.org/tmp/102918/screen_shot_mathjax.jpg

The HTML for toc is
==================
<div class="tableofcontents">
<span class="sectionToc" >1 <a
href="#x1-20001" id="QQ2-1-2">Listing of integrals</a></span>
<br />    <span class="subsectionToc" >1.1 <a
href="#x1-30001.1" id="QQ2-1-3">
\(\DOTSI \intop \ilimits@ e^x \left (1-x^3+x^4-x^5+x^6\right ) \tmspace +\thinmuskip{.1667em} dx\)</a></span>
<br />    <span class="subsectionToc" >1.2 <a
href="#x1-40001.2" id="QQ2-1-4">
\(\DOTSI \intop \ilimits@ \frac{e^{\frac{x}{2+x^2}} \left (2-x^2\right )}{2 x+x^3} \tmspace +\thinmuskip{.1667em} dx\)</a></span>
</div>
===============================

Compiled the above using same command I used in earlier examples,
which is

make4ht -ulm default  -c ./nma_mathjax.cfg report.tex
      "htm,0,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

Where nma_mathjax.cfg is

-------------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
-------------------

And mathjax-latex-4ht.sty is from

https://github.com/michal-h21/helpers4ht/blob/master/mathjax-latex-4ht.sty

If I compile the same file using svg for math or just using default
setting for make4ht , then the TOC is correct.

      make4ht -ulm default  report.tex

No issue. Again, this from large files that always used to compile
OK and TOC with math in it had no issue showing in HTML before.

Does one need to modify something in the mathjax-latex-4ht.sty to
make the TOC show OK? Do I need to modify something in my Latex to
make it work with mathjax?

TL 2018.

Thank you

This is the same issue as you had with \left and \right in TOC some
time ago. The \int and \, commands must be redefined to not expand in
TOC. I've updated mathjax-latex-4ht and created new command:
\fixmathjaxtoc. It takes command name as an argument and redefines it
so it doesn't expand.  You can use it in your .cfg file in this way:
\fixmathjaxtoc\int. But you should let me know about unsupported
commands anyway, as I should fix the sources as well.

Best regards,
Michal

Thanks Michal;

Your new style file fixed some of the problems in the TOC,
but I see few other entries in the TOC still have problems
when I run it on my main file (not the MWE I gave)

I guess these needs to be added to \fixmathjaxtoc.

btw, I did not have to do anything to my .cfg? I just needed to
download your new style file which has this command in it.

I now running the full build and will make list of all
these commands that needs to be added.

There is over 70,000 entries in the TOC spreads of hundreds of
web pages anbd it takes days to compile, so it will take me
sometime to make a list of all of them and give it to you.

For example on one file, I get now this TOC in HTML (using
your new updated style file). You can see some still needs
to be fixed

https://www.12000.org/tmp/102918/screen_shot_mathjax_2.jpg

While the same file using svg looks like this

https://www.12000.org/tmp/102918/screen_shot_svg.jpg

Thanks again for your help.

Hello Michal;

There were lots of errors, but the good thing it seems they
all are related to the latex math names not working in toc.

So I edited your mathjax-latex-4ht.sty file on my PC
and added these entries to what you allready have there:

\fixmathjaxtoc\sin
\fixmathjaxtoc\cos
\fixmathjaxtoc\tan
\fixmathjaxtoc\arcsin
\fixmathjaxtoc\arccos
\fixmathjaxtoc\arctan
\fixmathjaxtoc\csc
\fixmathjaxtoc\sec
\fixmathjaxtoc\cot
\fixmathjaxtoc\sinh
\fixmathjaxtoc\cosh
\fixmathjaxtoc\tanh
\fixmathjaxtoc\coth
\fixmathjaxtoc\log

To the section where it says

     % fixes for tables of contents

I've rebuild few files and I longer see the problems in the TOC.

I still need to rebuild all the files and check each visually just in
case I missed some other math name not listed above.

This will take few more days since there are hundreds of files
to build and check.

If I found one I missed, will email you so you can add it to you
master style file on git.

Thank you
--Nasser

Subject: [tex4ht] Automatic HTF file generation
Message-ID: <CAOCj1OfLMux-j3Fx1UZPt141gbAHEjY6eAu-444X9NMYgcfOwA@mail.gmail.com>

Hi all,

I've finally finished the Htfgen project [1]. It's objective is to
automatize the creation of the HTF font mapping files. These files are
used by tex4ht to map character codes in the DVI files to Unicode.

There are two new scripts: scanfdfile and dvitohtf. The first one
searches for declared fonts in the FD files, the other generates
literate TeX file for HTF generation. Sample usage is as follows:

   cat /usr/local/texlive/2018/texmf-dist/tex/latex/ebgaramond/*.fd |
scanfdfile | dvitohtf > ebgaramont-htf.tex
   tex ebgaramont-htf.tex

This will create HTF files for all detected fonts defined in FD files
for EB Garamond.

dvitohtf can also generate HTF files for missing fonts in the DVI
file. So if tex4ht reports missing HTF files, it can be used directly
on the DVI file:

   dvitohtf sample.dvi > missing.tex
   tex missing.tex

dvitohtf supports both virtual and tfm fonts. It looks for virtual
fonts first, the tfm file is used only when no vf is found. It looks
for all fonts referenced in the virtual font and tries to look for
corresponding .enc files in pdftex.map. The .enc files contain glyph
lists, which are then mapped to Unicode.

It also parses the .pfb file for font family name and tries to detect
style (italic, bold, small caps) from the font full name saved in the
.pfb file.

It computes hashes for the font tables, so duplicate font tables
aren't written, the fonts with same characters just link to the first
used font.

If no .enc file is found, then the font cannot be supported. There can
be also missing mappings between glyphs and Unicode. The missing
mappings are reported in the TeX file.  Htfgen contains large mapping
files, but some fonts just use some custom glyphs which doesn't have
Unicode equivalent. For example Q_u ligatures etc. In this case the
mapping must be added by hand to glyphlists/glyphlist-fixes.txt.

It works reasonably well for fonts generated by Fontinst, because they
usually use standard glyph names, contains .enc files, etc. For
complex virtual fonts, especially math, it fails. HTF files for such
fonts still needs to be created by hand.

What to do now? There are some wrong HTF files in tex4ht sources, for
example Linux Libertine support is wrong for some ligatures. I am sure
there will be more examples, especially fonts with large number of
ligatures. Their support has been added few years ago, but only in T1
font encoding. We should remove HTF generation for these files from
the huge literate sources for fonts and create smaller literate TeX
file for each of these fonts. This should speed up the tex4ht build
and it should be easier to manage.

Any volunteers are welcomed.

Best regards,
Michal

It's awesome.

Encoding vector is always embedded in Type1 font. If encoding vector is
not specified in map file, you can get it from pfb/pfa file.

I'm not sure about this. Probably it is the way to go (if it makes maintenance easier).
We are talking here about hundreds of smaller literate sources and thousands of htf files, right?
IMHO literate sources are good for manual editing and documentation.
Auto-generated literate sources would not be meant for manual editing, would it be?

Did you consider generating htf files directly?
How do you test these htf fonts?


I'm sorry, I have too many lame questions...

You are right, I did't know about that. It should fix most of the
problems. It shouldn't be hard to write parser for the /Encoding
array.

We can of course generate the htf fonts directly, the literate sources
are just easier to maintain and to keep in SVN. They are not meant for
editing, althouth some mechanism for hand crafted HTF should be
invented.

> Did you consider generating htf files directly?

Just some test documents, we should create a proper testing framework
for fonts (and other files of course too, but this is another
question)

These were good questions :)

Usually the /Encoding vector in a given Type 1 is only a subset of the
characters available in the font. The only way to know what is there is
to parse the entire file. But there are lots of utilities in this area;
I suspect something out there will dump a list of characters from a pfb. -k

I will parse the .pfb files only when no enc is available. We will see
how it is useful. Worse thing is large number of non-standard glyph
names used in TeX fonts. We need to map each glyph to Unicode, it is
not always easy to find a correct mapping.

Michal

It turned quite well, it works even for complex math and symbol fonts.
The only issue is that these fonts often use custom glyphs which I
cannot find Unicode equivalent for. For example, it works for this old
issue, which prompted me to create Htfgen in the first place:

https://puszcza.gnu.org.ua/bugs/?236

The attached file contains literate source file for fonts required for
the DVI file used by Nasser's sample. Note that it contains huge
number of "Missing glyph" messages. These won't work until glyph to
unicode mapping is added to Htfgen.

Michal

Subject: [tex4ht] problem using \sl and \sc in tex4ht when using matghjax
	mode
Message-ID: <98de60b3-f7bc-1667-1e79-5824a85a342e@12000.org>


There is problem translating Latex code to HTML when using
mathjax mode when latex uses the old \sl and \sc commands.

This is code generated by Maple Latex so it is not possible
to change it and not practical to edit it by hand each time
since this is autogenerated each time the files are compiled.

Maplesoft seems to have abandoned working maintaining its
Latex export for some other exotic math rendering software
so no chance this will fixed by them.

I do not know what I need to change in mathjax-latex-4ht.sty
to fix this.

Here is a MWE

----------------
\documentclass[11pt]{article}

\usepackage{amsmath,mathtools,amssymb}

\begin{document}
\begin{align*} %code below is copied from part of Maple's Latex
u  &= s{{\sl I}_{0}} \\
    &= s{{\sc I}_{0}} \\
    &= s{{\rm I}_{0}}
\end{align*}

\end{document}
------------------------

When compiled using mathjax mode, it gives

https://www.12000.org/tmp/11182018/screen_shot.jpg

I also tried using this class istead

\documentclass[11pt,enabledeprecatedfontcommands]{scrartcl}%this also fail

I also tried adding

\makeatletter
\DeclareOldFontCommand{\sl}{\normalfont\slshape}{\@nomath\sl}
\DeclareOldFontCommand{\sc}{\normalfont\scshape}{\@nomath\sc}
\makeatother

But had no effect on resulting HTML.

This seems to affect only \sl and \sc commands, but there
might be more.

Is it possible to change mathjax-latex-4ht.sty to work around this?

The command I used to compile is the same as before and described
here

===================
make4ht -ulm default  -c ./nma_mathjax.cfg report.tex
       "htm,0,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

Where nma_mathjax.cfg is

-------------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
-------------------

And mathjax-latex-4ht.sty is from

https://github.com/michal-h21/helpers4ht/blob/master/mathjax-latex-4ht.sty

========================

This problem only shows with mathjax. No problem when using SVG.

Thank you for any help.

This needs to be fixed in the MatJax configuration, the definitions on
TeX side don't have any effect on MathJax.

The configuration may look like this:

------------------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\Configure{@HEAD}{\HCode{
<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    TeX: {
      Macros: {
        \unexpanded{
        sc : "\\small\\rm",
        sl: "\\it",
      }
    },
    }
  });
</script>
}}
\begin{document}
\EndPreamble
-------------------------

MathJax doesn't seem to support small caps, so we must fakt it a bit.
You may need to add more command definitions to the macros section in
the config file. Note that you can use only command supported by
MathJax. I am not sure if it is a good idea to to add these
definitions to mathjax-latex-4h.

Michal

The above worked very well. I've added it to my .cfg file.

Now I just have to remember there are 2 places with MathJax.Hub.Config
setting. One in the personal .cfg and another place in the
mathjax-latex-4h.sty file.

Thank you for the help as always.

Message-ID: <9957dd1a-9716-bcfb-e7ef-2d850e54abb6@12000.org>


I just found a new problem that I can't resolve.

I had to use

\newcommand{\LommelS}[1]{\operatorname{LommelS#1}}

To correctly compile code in Latex generated by Maple.

I could not use \DeclareMathOperator{\LommelS1}{LommelS1}

since a number can't be at end of operator. I posted question
about this here

https://tex.stackexchange.com/questions/460667/declaremathoperator-not-working-on-some-math-names-with-a-number-at-the-end

And the answer given is what I am using. So the following MWE
works fine in lualatex and pdf

=====================
\documentclass[11pt]{article}

\usepackage{amsmath,mathtools,amssymb}
\newcommand{\LommelS}[1]{\operatorname{LommelS#1}}

\begin{document}
\[
  \LommelS1 x + \LommelS2 y
\]
\end{document}
=========================

However, when compiled using make4ht with mathjax mode
it does not work. It gives this

https://www.12000.org/tmp/11182018/screen_shot_2.jpg

I tried to do same Trick like Michal showed and changed my .cfg
to use

\Configure{@HEAD}{\HCode{
<script type="text/x-mathjax-config">
   MathJax.Hub.Config({
     TeX: {
       Macros: {
         \unexpanded{
         sc : "\\small\\rm",
         sl: "\\it",
	LommelS1: "\\LommelS1 ",
	LommelS2: "\\LommelS2 "
       }
     },
     }
   });
</script>
}}

Tried few other things above, but nothing is working.
I do not understand what mathjax wants me to type above.

There is no issue when compiling with SVG.

Is command such as \newcommand{\LommelS}[1]{\operatorname{LommelS#1}}
not supported in the translation to HTML using mathjax?

I used sthe ame command to compile this as I just showed in last email.
But for completion, here they are

make4ht -ulm default  -c ./nma_mathjax.cfg report.tex
        "htm,0,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

Where nma_mathjax.cfg is

-------------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
-------------------

Any workaround with this issue?

Thank you

You must provide declaration for the \LommelS macro:

\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\Configure{@HEAD}{\HCode{
<script type="text/x-mathjax-config">
   MathJax.Hub.Config({
     TeX: {
       Macros: {
         \unexpanded{
         sc : "\\small\\rm",
         sl: "\\it",
        LommelS: ["\\operatorname{LommelS\#1}",1],
       }
     },
     }
   });
</script>
}}
\begin{document}
\EndPreamble


You can use the same declaration as Egreg provided, it is just
necessary to declare it to have a parameter. See the MathJax
documentation for this:

https://docs.mathjax.org/en/latest/tex.html#defining-tex-macros

Michal

 mathjax mode, why?
Message-ID: <234dfb14-3c27-2dee-e63c-20700d6fb7c5@12000.org>


Maple generates wrong Latex code. It generates \tauL  when it should
be \tau L.

As a workaround until Maplesoft fixes its latex code (which will never
happen), I defined a command to change \tauL to \tau L and
added it to the preample.

This solution works OK in pdf and also when compiling to HTML in SVG.

But when compiling using mathjax mode, the \newcommand is not having
any effect, as the generated HTML still shows \tauL.

Here is a MWE

===================================
\documentclass[11pt]{article}
\usepackage{amsmath,mathtools,amssymb}

%\newcommand{\tauL}{\tau L} %Another option to use

\usepackage{xspace}
\newcommand{\tauL}{\ensuremath{\tau L}\xspace}

\begin{document}
\[
    {\rm d}\tauL \sin(x) %bad code generated by Maple.
\]
\end{document}
====================================

Here is how the HTML looks in mathjax vs. svg

https://www.12000.org/tmp/11202018/screen_shot.png

As a workaround, I used the method given by Michal and add this
configuration

%thanks to Michal Hoftich. Added Nov 18, 2018 to handle Maple Latex export problem
\Configure{@HEAD}{\HCode{
<script type="text/x-mathjax-config">
   MathJax.Hub.Config({
     TeX: {
       Macros: {
         \unexpanded{
         sc : "\\small\\rm",
         sl: "\\it",
	LommelS: ["\\operatorname{LommelS\#1}",1],
	tauL: "\\tau L"    <----- add this, now error is gone
       }
     },
     }
   });
</script>
}}


And now it works in mathjax.

But my question is: Why \newcommand inside Latex had no effect
when compiling to mathjax but it work in SVG?

Hi Nasser,

> But my question is: Why \newcommand inside Latex had no effect

Because the \newcommand isn't included in HTML so MathJax cannot see
it. Moreover, it is quite possible that you will need different
command declarations for LaTeX and MathJax.

In the SVG mode, part of rendered DVI file is converted to image, the
DVI file contains result of full macro expansion, so it doesn't suffer
from such issues. MathML output also contains all commands expanded.

Best,
Michal

Message-ID: <CAOCj1OcUumZOHb1w2RsXGqc0OMq1UoJ+iB_eDOAToAoLCu3iJQ@mail.gmail.com>

Hi all,

I've added some new features to tex4ht. They are available in the HTML
output mode.

The first feature is simpler way to include external CSS and
JavaScript files. Two new configurations are available: AddJs and
AddCss. They can be used as follows:

\Configure{AddJs}{hello.js}
\Configure{AddCss}{hello.css}

These commands just insert the correct HTML tags to the document and
register these files for post-processing, so they can be copied to a
output directory or post-processed using filters.

The second feature is webfonts support. Again, it just inserts some
CSS instructions and registers the font files for a post-processing. I
think the main use case for this feature is in ebooks, where fonts can
be bundled.

More information can be found here:
https://github.com/michal-h21/tex4ht-doc/blob/master/sections/webfonts.tex

This MWE (which from auto-generated by Scientific word when asking it
to align one very wide equation on multiple lines, so
I have no control on avoiding using multline since that
is what SW choose to do it internally when it generates
the Latex code.

-------------------------------

\end{multline*}

\end{document}
----------------------------

The above compiles OK in lualatex and in tex4ht using SVG for math,
but in mathjax mode the HTML is empty:

</body>
</html>

command used is

make4ht -ulm default  -c ./nma_mathjax.cfg foo.tex
    "htm,0,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

and nma_mathjax.cfg  is

------------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble
------------------------

I googled multiline and mathjax and can't decided if it supports it
or not so far.

If mathjax does not support multiline environment, is there a way
to configure this using mathjax-latex-4ht.sty somehow? any other
suggestions what to do?

It was a bug in mathjax-latex-4ht, I didn't know that images are
requested for these environments, so the \VerbMath{multline*} wasn't
enough. It should be fixed now.

Best regards,
Michal

Follow-up Comment #1, bug #405 (project tex4ht):

I've posted an answer on TeX.sx. I will copy it here as well:



You are right, small piece of CSS can fix that:

\Preamble{xhtml}

\Css{li img{vertical-align:middle;}}
\begin{document}
\EndPreamble

tex4ht doesn't try to match visual appearance of the PDF version in HTML, so
it is necessary to style it according to your needs sometimes.

Hi all,

I've just added new literate source to tex4ht,  tex4ht-mathjax.tex. It
is a modified version of mathjax-latex-4ht.sty from the Helpers4ht
project [1]. I've also added the "mathjax" option to `html4-math.4ht`,
so it should be possible to require the MathJax rendering of math
using this option. I need to add this option also for the MathML
output.

Anyway, with this option it will be possible to use MathJax directly using

    make4ht filename.tex "mathjax"

without need to use Helpers4ht and configuration files.

Best regards,
Michal

Thanks Michal.

But I can't get it to work. Is this supposed to be in the source now?
I just did now _full_ update for TL 2018.

Two issues
===========
1) when I compile a file, it generates png images and do not do mathjax.

2) when I use my main .cfg, now I get error

make4ht -ulm default -c ~/nma_mathjax.cfg foo.tex "htm,mathjax"
=================================
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html4-math.4ht)
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html5.4ht)) (./foo.aux)
! Undefined control sequence.
l.184 \ExplSyntaxOn

?
======================================
  
Because in my main .cfg file, I am using \ExplSyntax on.


But lets stay with the first issue for now. Using this MWE

==================================
\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{graphicx}
\begin{document}

\begin{multline*}
A \sin x+\\
\cos x=0
\end{multline*}

\end{document}
=========================

Compiled using

make4ht -ulm default -c ./nma_mathjax.cfg foo.tex "htm,mathjax"

Where the local .cfg above is this:

=========================
>cat nma_mathjax.cfg
\Preamble{xhtml}
\begin{document}
\EndPreamble
>
=====================

So I removed the first line that was there which was

\RequirePackage{mathjax-latex-4ht}

Becuase you said it is no longer needed?

But now it generaes png for images. Looking at the HTML,
there is no mathjax configuration at all in it.


Same thing if I use

     make4ht foo.tex "htm,mathjax"

Am I doing something wrong? Or may be the updates are not
there yet?

Thanks

It is only in the source, I think Karl will say when it is available
in TL. It may take few days.

Thank you again and to Karl also.

I updated TL just now and it look like sources are in now.

Hi Nasser,

I've forgot to anounce that I updated also latex.4ht, which contains
\NewConfigure{MathjaxSource}. It cannot work without this definition.
The correct version of latex.4ht is attached to this email.

Another issue is that you probably require mathjax-latex-4ht.sty in
your .cfg file. You need to remove it, because it clashes with the
code defined in tex4ht now.

Best regards,
Michal

Thanks Michal.

I overwrote

/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/latex.4ht

with the file you attached and now make4ht foo1.tex "htm,mathjax" using
the example latex I posted in my last email does _not_ give an error
any more.

But I found another syntax error testing it more.

This MWE

=====================================
\documentclass[12pt]{article}
\usepackage{graphicx}
\usepackage{amsmath}

\begin{document}

\begin{align*}
\overrightarrow{\sum}F_x  &= Mx'' \\
F(t) -kx -H               &= Mx'' \tag{1}%
\end{align*}

\end{document}
=========================================

Gives an error compiling using make4ht foo1.tex "htm,mathjax"

=====================
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html4-math.4ht)
(/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html5.4ht)) (./foo1.aux)
! Misplaced \cr.
\math at cr@@@ ->\cr

l.11 \end{align*}

? x
==================

It compiles OK using  make4ht foo1.tex "htm" and compiles OK
with lualatex and compiles OK with SVG for math. Only in mathjax
mode it gives error.

Any idea why this now fails in mathjax mode? I am sure this
compiled OK  in mathjax before the latest updates.

Thank you for your help.

Yes, it seems that configurations for math environments didn't take a
place. Try the attached fixed version of mathjax-latex-4ht.4ht.

Best,

Thanks Michal. I replaced

/usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/mathjax-latex-4ht.4ht

with the file you attached and now the error went away.

But I am little confused. Even though the file compiles ok now using
make4ht foo.tex "htm,mathjax"  the math does not display at all.

I looked at the HTML generated and see no place where it loads mathjax.

ie. I see no

\Configure{@HEAD}{\HCode{ <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-AMS-MML_HTMLorMML"></script> \Hnewline}}

like you had in the old mathjax-latex-4ht.sty file (which I no longer use).

Is a user now supposed to add the above line to their .cfg manually? If so,
no problem, I can do this but it was not clear.

thanks

It should be included in html4-math.4ht, in the configuration for
MathjaxSource. Does the attached version work?

hi Michal,

It is allready in html4-math.4ht

>grep -i  cdnjs /usr/local/texlive/2018/texmf-dist/tex/generic/tex4ht/html4-math.4ht
\Configure{MathjaxSource}{https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-AMS-MML_HTMLorMML}

I found why it does it now work on my end.

When I use my .cfg, the above line does not show in the HTML.

I did remove the old require mathjax-latex-4ht.sty from my .cfg.

But I think the reason is that my .cfg has additional mathjax
configurations I needed which you said to add it to .cfg before,
since I could not add it to mathjax-latex-4ht.sty. It uses
your

\ExplSyntaxOn
\regex_replace_all:nnN{ \x{23}\x{23}}{\x{23}}{\mymathjaxconf}
\ExplSyntaxOff

trick.

May be the order is now messed up from before when it worked?

Because I am doing additional MathJax.Hub.Config({ in my .cfg,
which does show in HTML, something now went wrong? This all worked
before. I need these additional fixes in my .cfg.

I am attaching my .cfg file. Can you please try on your end?

THis is how I called it

make4ht -c ./nma_mathjax.cfg foo1.tex "htm,mathjax"

Now mathjax do _not_ load in HTML, but when I do

make4ht foo1.tex "htm,mathjax"

Then it loads. Any work arounds?

Getting Mathjax to work is hard!

Thank you,

The issue is that you use \Configure{@HEAD}{} in your configuration
file. It removes all configurations that goes to the HTML header,
including MathJax loading. In fact, I don't think you need to
configure VERSION, DOCTYPE, HTML and first three @HEAD (for charset,
generator and css file). You should just remove it, make4ht already
produces HTML 5 file.

Best regards,
Michal

hi Micahl;

But this is severe restriction now that users can no longer
use \Configure{@HEAD} in their .cfg files?

I need to use \Configure{@HEAD} to add javascript code

\Configure{@HEAD}{\HCode{<SCRIPT TYPE="text/javascript">
etc...

For many other things I need not related to mathjax, which
I did not show in the file I send since it was not related.

I load lots of other Javascript libraries etc... using HEAD. One
such example is

\Configure{@HEAD}{\HCode{
     <script type="text/javascript" src="/scripts/gifffer-master/lib/gifffer.js"></script>\Hnewline
<script>
    window.onload = function() {
    Gifffer();
    }
</script>\Hnewline	
}}

and others like it.

How else would one do these things if one can't do them using HEAD in
my common site .cfg file?

Is it posssible to design your mathjax configuration without this restriction
on users .cfg not being able to use \Configure{@HEAD}
by any chance? In the way you had it before, this was not an issue
and it worked well.

Thank you,

You can use \Configure{@HEAD}{some code}, just not
\Configure{@HEAD}{}, because it removes all additions to @HEAD before
that point. This is also why you use all those
\Configure{@HEAD}{\HCode{<meta charset="UTF-8" />\Hnewline}}. It is
not necessary anymore. I think this comes from a old configuration
file for MathJax which predates the HTML5 support in tex4ht.

Thanks Michal;

Sorry I miss-understood you. I removed \Configure{@HEAD}{}
and now it works, but kept the other ones.

All this initial \Configure{@HEAD}{} code I had there for ever, for
many years now. But I removed it now for mathjax to work.

Will now test your new set up more in my main build and will report
any problems I find since things seems to have settled OK now
to use it.

Message-ID: <bf00f06b-1309-9767-b4d8-14dcaf484451@12000.org>


Hello;

eqnarray does not work in mathjax mode.

I do not use eqnarray myself explicitly any more, but
this is from old latex files and noticed it does not work in mathjax:

=======================================
\documentclass[12pt]{article}

%test for eqnarray in mathjax
%\usepackage{amsmath}%not needed for eqnarray

\begin{document}

\begin{eqnarray*}
   \rightarrow\sum F&=& M x''   \\
   F \left( t \right)  + k R \theta + b R \theta' + H &=& M x''
\end{eqnarray*}

\end{document}
========================================

Compiled with

make4ht foo.tex "htm,mathjax"

The generated image in png for some reason, and not mathjax rendered.

=============================
</head><body >
    <div class="eqnarray">
    <center class="math-display" >
<img src="fo0x.png"
alt="  &#x2211;             &#x2032;&#x2032;
        &#x2192;     F   =   M x
F \lef t(t\right) + kR &#x03B8; + bR &#x03B8;&#x2032; + H  =   M x&#x2032;&#x2032;
" class="math-display"  /></center>
</div>
=========================

It looks like this

https://www.12000.org/tmp/1292018/screen_shot.png

The question is, is eqnarray supposed to work in mathjax?
googling around I see examples where it works in mathjax on
the net.

Thank you,

The following MWE does not compile OK in mathjax mode.
It works in lualatex and in default mode and in SVG mode.

=============================
\documentclass[12pt]{article}

\usepackage{amsmath}
\begin{document}
\def\st{\sin\theta(t)}
\begin{align*}
\dot{\theta}(t)  &  = \st
\end{align*}
\end{document}
================================

Compiled using

make4ht foo.tex "htm,mathjax"

It gives

https://www.12000.org/tmp/1292018/screen_shot_2.png

The problem is in the use of \def\st{\sin\theta(t)}

The latex code might not be the best, but it works
in the other systems.

Workaround for mathjax is easy, change it to

========================
\begin{document}
\begin{align*}
\dot{\theta}(t)  &  = \sin\theta(t)
\end{align*}
\end{document}
=======================

is \def not supposed to work in mathjax mode?

Thanks

Just add the macro definition to the MathJax configuration as in

Message-ID: <6b3da467-417d-4e6e-5fb6-1c35ba5848db@12000.org>

This is probably the weirdest problem I found using mathjax.

I am having hard time understanding how to work around this
problem.
  
The same HTML generated using mathjax mode looks Ok on my computer
but does not look OK after ftp'ed up to the the server then looking
at it in the browser there.

Here is a MWE

-------------------------------------
\documentclass[11pt]{article}%
\usepackage{amsmath}
\begin{document}
Therefore
\[
A=0\
\]
Hence
\end{document}
----------------------------------

Any one notice any problem with the above code? It is
valid latex and compiles OK with all systems.

Compiled this using

       make4ht foo1.tex "htm,mathjax"

And there is _NO_ problem, when I view it on my computer, running
windows 10, via localhost: URL using my local apache web server running
on windows.

Here comes the issue. I ftp the above HTML file to my hosting server
and then view it there, now it is no longer working.

The same exact HTML file and .css.
   
Here is screen shot side by side. Both views are using Chrom browser.
One on local PC and one on the server.

https://www.12000.org/tmp/122018/screen_shot.png

When I view source of the page on screen, it looks the same as on my PC

</html>
====================================

The web hosting server runs Linux Apache. So it could be some encoding
issue.

The problem goes away when changing

\[
A=0\
\]

to

\[
A=0
\]

Now you might ask, when I wrote A=0\ there instead of A=0? I did not.
This is fragment of code generated by Scientific word. SW tends to add
lots of \ for spacing everywhere.

Next, I went to this file DIFF free site, which does byte by byte difference.

I copied the HTML on my PC and the HTML on the server and compared them
side by side.

It turned out that on the server the _carriage return_ after A\ was
stripped out!, so the code on the server actually is A\\]  while on the PC
the CR is still there, so it actually like this

      A=0\
      \]

Here is screen shot side by side the file difference. Left
screen shot is on the server, and right side is same HTML on the PC

https://www.12000.org/tmp/122018/diff.png

note that there is no issue with the code as is compiled in latex or SVG for
math. Only issue is with mathjax and only when ftp'ing it to the Linux server.

Any suggestion what one should do to avoid this problem? Is problem this to
be expected?

luckily this problem does not show in many places. For now, I can manually
remove the \ after the A. But SW will put it back next time
I edit the file. And this problem could be there in many
other places also but I have not noticed it before.

I am using TL 2018

>make4ht --version
make4ht version v0.2c

Problem solved.

I use filezilla FTP software. Been using it for years with
Its default for AUTO for file type transfer.

I now changed the file type to be explicit BINARY
and now when I upload the HTML generated, the carriage return
is not stripped. It is there.

So mathjax is happy and now it looks the same as it does
locally.

This is first time I had issue with the setting for FTP,
may be because before I was using images for math and this
was never an issue.

The default was AUTO, but now will make sure to change to binary
next time I install fillezilla. Even though transfering text
files between different OS's using binary can be a problem due
to different end of line encoding, but I compile everything
on Linux on the local PC even though the deskstop itself is
windows, so using binary for transfer should be OK.

Case seems to be closed.
Thank you

That's great that you found a solution, this particular issue would be
hard to track otherwise.

Best regards,

Details:

I will reproduce a report from the tex4ebook issue tracker [1]

---
The \chapter takes two parameters: in curly brackets (more common) and square
brackets (less common). If just curly brackets are used, that text is used for
both the TOC and chapter header. If curly and square are used, then the text
in square brackets are used by LaTeX for the TOC and the text in curly
brackets are used for the chapter header. Tex4ebook appears to ignore the
square brackets and use whatever's in the curly brackets for both TOC and
chapter headers. This is a problem for my current project because I have
newlines in the chapter names where they appear at chapter headers, but this
is ugly in the TOC.

In the context of this bug report, if only square brackets are used, it is
legal for demons to fly out of the author's nose.

 
\documentclass{memoir}
\begin{document}
\tableofcontents*
\chapter[First Chapter]{First\\
Chapter}
\chapter[Second Chapter]{Second\\
Chapter}
\chapter[Third Chapter]{Third\\
Chapter}
\end{document}

---

I don't know how to fix this yet.

Hi all,

The `svg` package can be used for inclusion of the SVG graphics in the LaTeX
documents. It uses Inkscape for conversion from the source file to EPS or PNG.
Since `tex4ht` and HTML supports SVG, this conversion step is unnecessary and
we can just include the picture directly (except for the ODT output, because
it doesn't support SVG). The basic support should be as simple as
`\renewcommand\includesvg[2][]{\includegraphics{#2}}`. 

There is one issue though. We already have a `svg.4ht` file, it is used by the
`tex4ht.4ht` for the `svg` option. I guess it should be safe to rename this
file to something like `svg-option.4ht` and use the `svg.4ht` for
configurations for the `svg` package.

Best,
Michal

I've renamed the svg.4ht file to svg-option.4ht and added basic support for
the Svg.sty package. I hope everything works.

Best, M.

Subject: [tex4ht] problems using mathjax mode with siunitx package
Message-ID: <982e3410-9c35-5c19-7775-b35ab8fecd3f@12000.org>

Hello;

I am trying the new mathjax mode with some old latex files
that make heavy use of \usepackage{siunitx}

None of the siunitx code works in mathjax but works OK
in lualatex and in png or svg for math with make4ht.

Here is a MWE

--------------------------------
\documentclass[11pt]{article}%
\usepackage{amsmath}
\usepackage{siunitx}
\DeclareSIUnit\ft{ft}

\begin{document}

\begin{align*}
  S  &=  \SI{2775}{\square\ft}
\end{align*}

\end{document}
----------------------

Compiled using

make4ht foo1.tex "htm,mathjax"

It looks like this in HTML

https://www.12000.org/tmp/122818/mathjax.png

The HTML generated is

--------------------------------------
<!DOCTYPE html>
<html lang="en-US" xml:lang="en-US" >
<head><title></title>
<meta  charset="iso-8859-1" />
<meta name="generator" content="TeX4ht (http://www.tug.org/tex4ht/)" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<link rel="stylesheet" type="text/css" href="foo1.css" />
<meta name="src" content="foo1.tex" />
  <script type="text/x-mathjax-config"> MathJax.Hub.Config({ 'fast-preview': {disabled: true},
TeX: { extensions: ["color.js","AMSmath.js"], equationNumbers: { autoNumber: "AMS" } },
extensions: ["tex2jax.js"], tex2jax: {  inlineMath: [ ["\\\(","\\\)"] ],
displayMath: [ ['$$','$$'], ["\\[","\\]"] ], processEscapes: true, processEnvironments: true } });
</script>
  <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-AMS-MML_HTMLorMML"></script>
</head><body>
<!--l. 10--><p class="noindent" >\begin{align*} S &amp;= \SI{2775}{\square \ft } \end{align*}
</p>
</body>
</html>
---------------------------

So mathjax does not know about siunitx.  Other than rewriting all the
latex code so not to use this package, which I really do not want
to do, is there a way to work around this? Is new
configuration needed somewhere? I have other\DeclareSIUnit macros
in the code such as

\DeclareSIUnit\ft{ft}
\DeclareSIUnit\deg{deg}
etc...

Using TL 2018
Thank you for any hints how to handle this.
