Dear Francis,
ah I see. It seems that I was wrong, mjcli uses MathML by default. When
you use the "mathjax" option, it uses the LaTeX math syntax for the
command line MathJax, but it doesn't remove the MathJax <script> element
from the HTML file. You can remove the MathJax <script> using following
.mk4 build file:
--------------------------------------
local domfilter = require "make4ht-domfilter"
local process = domfilter {
function(dom)
for _, el in ipairs(dom:query_selector("#MathJax-script")) do
el:remove_node()
end
return dom
end
}
Make:match("html$", process)
------------------------------------
Then there is the issue with MathML. It seems that there is an issue
with the LaTeX to MathML conversion in your case, so several things
fail.
First, make4ht process MathML and fixes some common issues. It fails, as
it reports the issue "Unbalanced Tag (/mstyle)". I suppose that the
mjcli error is caused by the invalid MathML too.
Could you try to make a MWE that runs into this issue? As I said, there
can be some issues that need to be fixed in the LaTeX source in the
worst cases.
Best regards,
Michal
I didn't explicitly use the "mathml" option. I wanted to use LaTeX
input to MathJax (because I've had problems with the MathML generated
by TeX4ht before), so I originally used the mathjax option, but that
included MathJax <script> elements in the generated HTML files, so you
advised me not to use it. I assumed that make4ht would then use MathML
because your document "The make4ht build system", Version v0.3g, says
in section 7.6 that:
-----
mjcli detects whether to use MathML or LATEX input by use of the mathjax
option for make4ht. By default, it uses MathML. LATEX input can be required
using:
make4ht -f html5+mjcli filename.tex "mathjax"
-----
I used the command
make4ht -f html5+mjcli manual reduce,3,xhtml " -cunihtf -utf8" -cvalidate
At the end of the run, make4ht reported several errors that all have this form:
-----

Each of the HTML files referenced in a similar message is empty and the other
messages reference the tags /msup, /mrow, and /munderover, which all look to me
like MathML tags.
On the non-empty output pages, some of the maths looks fine but some if it is
rendered noticeably differently from the version rendered by MathJax running in
a browser. The maths all looks slightly bigger, some brackets are too tall, and
the calligraphic font looks very different. In fact, I'm wondering whether the
browser is picking up the wrong font files. I haven't investigated further yet.
