tabulary broken after the June 2024 array package update.

[davidcarlisle]

All use of the package, for example

\documentclass{article}

\usepackage{tabulary}

\begin{document}

\begin{tabulary}{1.0\linewidth}{L}
  x
\end{tabulary}
\end{document}

Produce the error message

! Missing \cr inserted.
<inserted text> 
                \cr 
l.9 \end{tabulary}

? 

This should be fixed in the current head of this repository, but opening the issue for the record.

@jfbu @u-fischer @FrankMittelbach I think this is done and rollback is working I'll push to ctan at lunctime today unless anyone spots anything

[jfbu]

My test document passes but right now on a big document I get

! Missing # inserted in alignment preamble.
<to be read again> 
                   &
l.10648 \end{tabulary}

This is wih

(/Users/zzz/Library/texmf/tex/latex/tabulary/tabulary.sty
Package: tabulary 2024/06/04 v0.11 tabulary package (DPC)

I will need some minutes to try to provide a mwe. The above document may have one or two hack, I have to check and see if I can reproduce with nothing extra.

[davidcarlisle]

@jfbu if it's easier, you don't need to make a minimised example you could send a zip to me by email and I would have a look

[jfbu]

Error definitely involves external context from Sphinx, I am closing in on which of the hacks done on tabulary is now broken.

[jfbu]

This was a very complicated process for me because Sphinx does hack tabulary and some of it I do not have in my head anymore... (some of it is very complicated with \multicolumn and I got lost for half-an hour trying to understand it despite dozens of comment lines) but it turns out that the reason causing that crash is simply that Sphinx does \RequirePackage{colortbl}.

\documentclass{article}

\usepackage{colortbl}
\usepackage{tabulary}

\begin{document}
\begin{tabulary}{\linewidth}{J}
    Language
\end{tabulary}
\end{document}

[davidcarlisle]

@jfbu Thanks, You might hope that packages by the same author might work in combination... I'll see what I can do.... Now I wonder how come the testfile ty001-colortbl here works as that loads both packages.

[davidcarlisle]

@jfbu should work after 1428319 (thanks @u-fischer)

[FrankMittelbach]

while it is not yet on ctan ... you don't need the \cr if you unconditionally do \crcr afterwards

\cs_set:Npn \tbl_crcr:n #1 {
     \int_compare:nNnT \g__tbl_col_int > 0
         {
           \tbl_count_missing_cells:n {#1}
         }
     \crcr
   }

Not that it matters much

[davidcarlisle]

Ah true I may as well change that and then we should push same change to the format @FrankMittelbach

[davidcarlisle]

v0.11 submitted to ctan

[jfbu]

Thanks. My big document where the problem with colortbl surfaced after the first fix now compiles with the version in place at time of writing (2024/06/04 v0.11).

The MWE:

\documentclass{article}

\usepackage{tabulary}

\begin{document}

\begin{tabulary}{1.0\linewidth}{L}
  x
\end{tabulary}
\end{document}

still fails to compile with the update: tabulary (34368 -> 71455):

[...]
! Missing \cr inserted.
<inserted text> 
                \cr 
l.9 \end{tabulary}

@dbitouze Check your log, I think you will find you are still using v0.10. v0.11 with the update is on ctan but something went wrong with the integration to texlive
