tabularray's cmidrule causes the conflict between "modifyLineBreaks" and "lookForAlignDelims"

[tatsy]

It seems that when I use \cmidrule command in tblr environment (of tabularray), the "lookForAlignDelims" does not work properly due to the conflict with "modifyLineBreaks".

I got the following output with the command:

latexindent main.tex -l -m -r

The versions of Perl and latexindent in my environment are:

• Perl: v5.36.0
• latexindent: 3.20.1, 2023-01-07

Thank you in advance for your kind assistance.

anything else

When I remove \cmidrule from the above code, I could get the proper output as the following. Also, when I removed -m switch from my command, the table was formatted properly, though consecutive lines were not condensed into one.

\usepackage{tabularray}
\UseTblrLibrary{booktabs}

\begin{document}

\title{Hello}
\author{Hello}

\section{Table}

Hello world! Hello world!

\begin{table}[t]
  \begin{tblr}{colspec={Q[c]Q[c]Q[c]Q[c]}}
    \toprule
    aaaaaa & bbbbb & ccc & dd \\
    11 & 2  & 33 & 4          \\
    5  & 66 & 7  & 8          \\
    \bottomrule
  \end{tblr}
\end{table}

\end{document}

[cmhughes]

Thanks for this. I can confirm the behaviour. This is not intended.

I'll look into it and report back.

[cmhughes]

I think it's the combination of the dontMeasure and the -m switch.

[tatsy]

I agree with you that a bug is on the dontMeasure feature and think other features of lookForAlignDelims work fine as far as I checked. Thank you very much for your kind help.

[cmhughes]

Thanks again.

This is fixed and released as of https://github.com/cmhughes/latexindent.pl/releases/tag/V3.20.4. I'll get it uploaded to ctan next.

@cmhughes Thank you very much for your kind help! I look forward to the new release.
