Fatal:misdefined:LaTeXML::Package::Pool::pgfmathparse Can't call method 'expr' on an undefined value

luclaurent opened this issue · comments

I am currently using LateXML installed using homebrew (using brew install latexml --HEAD).
I have the following error on lateXML which is due to pgfmathparse (tikz):

Fatal:misdefined:LaTeXML::Package::Pool::pgfmathparse Can't call method 'expr' on an undefined value

Versions:

$latexml --VERSION
latexml (LaTeXML version 0.8.4; revision 7fe716a)

$ tex --version

$ pdflatex --version
pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020)

Thank you for the excellently organized issue @luclaurent ! I'm tagging it as a texlive regression for now, as the latest latexml master does well on your example on an older texlive ( as can be seen at https://latexml.mathweb.org/editor ). Will take a look!

If I am seeing correctly, this example is now processed correctly with the latest latexml, on texlive 2019:

example-texlive2020-latestlatexml

I still see some issues with texlive 2015, but there are no errors (just subtle interpretation bugs for tikz), so we may consider closing here?

I have tried again with the last version (LaTeXML version 0.8.4; revision 456c715) and I have the same errors. Are you sure you use TeXlive 2020?

Command: latexml test.tex

Ugh. Sorry for the false positive. I'm indeed looking at a texlive 2019, which I wrongly believed to be 2020. And thanks again for the log!

no problem.

After investigating, I have update all the Perl modules using cpan -u. Now latexml runs well on tikz example. I am not sure about the actual module(s) that need to be updated. In conclustion, the issue is not due directly to TeXLive 2020 but seems to be due to mixed conflict between Texlive 2020 and outdated perl configuration...

Currently I use perl version: (v5.18.4).

Modules versions:
Parse::RecDescent: 1.967015
XML::LibXML: 2.0205
XML::LibXSLT: 1.99

Alright, so in summary it's a shame it took us this long to troubleshoot this properly. The pgf-related bits are some of the more fragile bits of code we have, and they are definitely used differently between different texlive versions.

Great to hear that texlive 2020 behaves well with all dependencies sufficiently up-to-date, and thanks to Bruce for testing and spotting the problem. We can close here and move on I think? Hopefully we keep getting better in using the raw pgf tex as we move forward.
