Package causets (TikZ based)

[c-minz]

Thanks for the nice work.
I'm the maintainer of the LaTeX package causets, which is based on TikZ. I have been asked for support with the experimental arXiv feature that converts submissions to HTML using LaTeXML (issue tracker: c-minz/LaTeX-causets#3). While I had encountered errors in version 0.8.6, these are now resolved in LaTeXML version 0.8.8.
Here is an update.

Log files of test runs

The following logs are from test runs of the file test_causets.tex with latexmlc --dest=test_causets.html --includestyles test_causets.tex:

In LaTeXML v0.8.6: test_causets.latexml.log --- previous run with errors

In LaTeXML v0.8.8: test_causets.latexml.log --- updated run without errors

The PDF and HTML files (for the last run) are included in the package repo.

Remaining minor issues

The alt-text for diagrams

The latest package version v1.5 of causets has a new key-value alt={description} which stores a "description" of a diagram in the macro \causetAltText. The key (and the value stored in the macro) is for future support of alternative text with LaTeXML. To my knowledge, this key-value is currently not implemented in TikZ either.
The package version v1.5 has been released (and is available on CTAN) so that package users may already start utilizing the alt keyword. If the package needs to be updated to work with LaTeXML, then I will release a patch or new version. Let me know if there are changes to be implemented.

Baseline adjustment

The diagrams are rendered sufficiently well in HTML, but their alignment within inline text and mathematical expressions is not perfect. This seems to be solved (at least partially) with the TikZ baseline bugfix.

Spacing in mathematical expressions

When diagrams are used in mathematical expression (see example 5 in the test file), the generated figures are not treated as symbols --- i.e. the leading and trailing whitespace may have to be adjusted. Since this should also affect other TikZ-based packages (and TikZ in general), I could open a new issue for that.

[c-minz]

Since the run on version 0.8.8 finished with "No obvious problems", I prepared a bindings file in the package repo. If this file is sufficient, should I create a pull request?

Cool!

Please prepare a pull request, it would be great to have it contributed officially from your github account.

But when you open the PR, it would be nice if you could link us to a couple of examples using the binding -- and mention which texlive you tested with -- so that we can verify things are workable.

[c-minz]

I added a pull request (#2737) for lib/LaTeXML/Package/causets.sty.ltxml. The test files are in the package repository (https://github.com/c-minz/LaTeX-causets), which I all tested with bin/latexmlc --strict:

The main test file runs without issues*: test_causets.tex

The example files show some warning (coming from other packages), but run also without issues* otherwise:
causets_example1.tex
causets_example2.tex

My pdfTeX version is: 3.141592653-2.6-1.40.28 (TeX Live 2025), which includes causets v1.5.

(* except for some text label alignment and spacing issues that are rather TikZ issues --- see above)

[c-minz]

Since the minor issues about the rendering of text nodes is a general problem with TikZ, I opened a new issue #2738.
