Package broken on current TeX Live

[ArchangeGabriel]

After upgrading my TeX Live install today, which included https://tug.org/svn/texlive?revision=69870&view=revision, I’m facing an error compiling any document that use tabularray:

Since the issue came with the l3kernel update, I’ve also reported it at latex3/latex3#1458.

[josephwright]

As I've commented in the matching latex3/latex3 issue, this is because e.g. \prop_gset_from_keyval:Nn is being used with a variable that's not been declared first.

[cpierquet]

Same here, I hope there's be a fix for it :-)

[davidcarlisle]

Same here, I hope there's be a fix for it :-)

you just need to pre-declare the prop's, this is enough (I think)

\documentclass{article}


\ExplSyntaxOn
\prop_new:N\g__tblr_defined_hdash_styles_prop
\prop_new:N\g__tblr_defined_vdash_styles_prop
\prop_new:N\g__tblr_initial_table_prop
\prop_new:N\g__tblr_initial_rows_prop
\prop_new:N\g__tblr_initial_columns_prop
\prop_new:N\g__tblr_initial_cells_prop
\prop_new:N\g__tblr_initial_hlines_prop
\prop_new:N\g__tblr_initial_vlines_prop
\ExplSyntaxOff
\usepackage{tabularray}
\begin{document}

\end{document}

[cpierquet]

\ExplSyntaxOn
\prop_new:N\g__tblr_defined_hdash_styles_prop
\prop_new:N\g__tblr_defined_vdash_styles_prop
\prop_new:N\g__tblr_initial_table_prop
\prop_new:N\g__tblr_initial_rows_prop
\prop_new:N\g__tblr_initial_columns_prop
\prop_new:N\g__tblr_initial_cells_prop
\prop_new:N\g__tblr_initial_hlines_prop
\prop_new:N\g__tblr_initial_vlines_prop
\ExplSyntaxOff

Yes, obviously, tks for tip :-)

Edit : it's working ;-)

[lvjr]

There will be a new release soon. At this time please download the latest package file
https://github.com/lvjr/tabularray/raw/main/tabularray.sty
and replace the old one with it.

[lvjr]

Recently I discovered that there is Hyrum's Law:

With a sufficient number of users of an API,
it does not matter what you promise in the contract:
all observable behaviors of your system
will be depended on by somebody.

So maybe tabularray is not the only broken package.

[dbitouze]

So maybe tabularray is not the only broken package.

Indeed, e.g. acro is affected as well.

[josephwright]

Indeed, but this are definitely bugs in the relevant packages not in expl3

[lvjr]

@josephwright Is it a good idea to add test files for most maintained packages (only check whether these packages can be loaded with no error when a new latex release is made) to latex3 (also latex2e) repository so that these crashes could be fixed before users discover them?

[josephwright]

@lvjr We've considered that before but it's not workable: changes in packages would lead to breakage we can't track, etc.
