& and % in tblr cause an error despite verb option #358

Closed ysalmon closed 1 year ago

The following code causes an error \verb ended by end of line. \end.

\documentclass{scrartcl}

\usepackage{tabularray}

\begin{document}
\begin{tblr}{verb,colspec={c}}
\verb!&!
\end{tblr}
\end{document}

The same happens with %.

This is with tabularray 2022D and a freshly update texlive 2022, compiling with lualatex.

This is related to the tricky \catcode system in TeX and almost nothing can be done in the side of tabularray at present (see #13 for a future plan).

For % characters in \verb commands, you will also get an error if you use them inside a classical tabular environment. See #104 for a workaround for tabularray.

For & characters in \verb commands, you will also get an error if you use them inside a classical tabularx environment.

I am planning to add \fakeverb command to my codehigh package (see https://github.com/lvjr/codehigh/issues/11). Hopefully with the next release of codehigh package, you could easily write \fakeverb{&\%} to get &% in tabularray tables and other LaTeX commands.

I have uploaded a new version of codehigh package (with \fakeverb command) to CTAN.

Since version 2023A, verb option was obsolete. Please use \fakeverb command instead.
