Hi Vitus, list.
My memory is quite fuzzy on this and I won't have a chance to take a
deep look until later, but I will try to share the information I have.

3. Any LaTeX environment name foo is changed to foo* (except it already ends
with an
asterisk). For example, \begin{tabular} is changed to \begin{tabular*}; same
for
\end{tabular}. But tabular* differs from tabular in needing an extra
width-argument, so
the export won’t work properly.
I had submitted a patch trying to address this
(https://list.orgmode.org/87h7ok3qi2.fsf@dell-desktop.WORKGROUP/, I have
attached a new version rebased on main to this message). It never made
it in and I failed to follow-up. This patch (or something similar)
could help with this issue. It basically only adds the star for math
environments (using org-html--math-environment-p)

Now the newline commands \n before and after %s are exported as whitespace.
Just replacing
\n%s\n by %s (that is, leaving the newlines out) solves the problem. HTML
ignores newlines
anyway.
This seems to work better indeed; the \n's were just cosmetic.

1 Create a new variable ox-html-latex-environments-no-number of the form
("foo"
"bar" "baz" ...), which contains all environments that should not receive
equation
numbers.
I don't know whether org-html--math-environment-p (as used in the
attached patch) is sufficient to determine whether we need to add a star
to the environment or if we need another variable (in my use cases,
testing for a match environment is sufficient but it may not be the case
in general).

I don’t know how to express in elisp what is in brackets, though. Does this
make sense to you? I
am a beginner with elisp, so I can only state the ideas I have but not
implement them (yet).
This can be made to work if there is a consensus that we want to add a
ox-html-latex-environments-no-number variable (I can try to help with
that if needed, even though my elisp isn't great)

(let ((formula-link
(org-html-format-latex
(org-html--unlabel-latex-environment latex-frag)
processing-type info)))
The patch should address that, I would be curious to see if you
encounter additional problematic cases after applying it.
Thanks for resurrecting this and for your help detecting and fixing the issues.
Best,
thibault

Subject: [PATCH] lisp/ox-html.el: Fix automatic numbering of non-math
environment
* ox-html.el (org-html-latex-environment): Prevent addition of * to
non-math environments. Added * is used for math environments to
replace latex equation numbering by org labels for html linking.
